Exchange Rate Factors: What Global Events Mean for Savvy Investors

When Russia invaded Ukraine in 2022, it created ripples in all financial markets, including currency markets. The Euro weakened while the dollar surged and emerging market currencies wobbled. Global factors can quickly affect financial markets and shake established trends. Apart from such rare events, currencies tend to change their price because of interest rates, inflation, and overall investor confidence. For investors managing money abroad, understanding these movements is critical to avoid losses and mitigate risks.

Below, we will break down how global political, economic, and cultural events influence exchange rates, with insights for savvy investors.

Economic factors

There are several key exchange rate factors with a consistent history of shaking financial markets. These factors include inflation, interest rates, trade balances, employment rates, and so on. Since economic factors are shaping markets almost daily, we start with those.

Inflation and interest rates

Inflation and interest rates are closely connected as one can easily affect the other. When inflation rises, central banks step in and raise interest rates to reduce inflation, and when inflation is lower, central banks can lower interest rates to make borrowing money cheaper. As a result, investors closely monitor these two metrics to anticipate changes in interest rates. Higher inflation makes currencies weaker, and whenever banks change the rates, the changes are immediately reflected in global currency rates. In the United States, the Federal Reserve is the central bank that sets interest rates in the country.

Trade balances and economic growth

A country that exports more than it imports has a stronger demand for its currency. More demand equals a stronger currency. However, the Japanese yen was always weaker against the dollar because the BOJ of Japan tends to have super low rates near 0 to support its exporters. Economic growth also increases demand for local currency as more investors try to invest in the country’s economy. Long-term investors often track this data to detect early signs of any changes in currency strength.

Political and geopolitical factors

Elections, sanctions, and overall political stability are also crucial factors. If the country gets under sanctions, its economy crumbles and its currency becomes inflationary, losing its value quickly. Elections are also crucial for a currency’s strength. Geopolitical events can have a serious impact on the currency as well. The most obvious example is the 2016 Brexit events that made GBP lose its value rapidly and violently. Global conflicts, such as wars, can seriously impact global financial assets, especially currency markets. When tensions are high, safe-haven currencies like USD and CHF (Swiss Franc) become very popular among investors as they seek a safe place to protect their capital.

Cultural and social factors

People like tourists, workers, and diaspora communities can shape currencies as well. Tourism usually drives seasonal demand, and countries that are popular destinations during certain seasons experience their currency appreciation as demand spikes. The perception matters as countries seen as safe and opportunity-rich tend to attract more investors, solidifying their currency strength.

Technology and innovation

Technology is seriously affecting everything, especially the financial sector. Digital payment systems, blockchain technology, and fintech startups have made it easy and swift to move money around. Cryptos and stablecoins enable investors to protect their capital using stablecoins during volatile times. The latest trend among banks is to work on CBDCs, which signals a new era where national currencies are blended with technology and blockchain. Despite this, currencies, even in their crypto form, will continue to be influenced by all major factors mentioned above, and knowing how these factors impact your currency is key to keeping your capital safe from risks.

Practical lessons for savvy investors

So, what do all these factors teach us about global currency rates and investing strategies? The key lies in proper preparations and anticipation. Monitoring macro trends, policy announcements, and major geopolitical and political developments is critical.

Diversify

The number one method which is used by professional investors is diversification. This simply means to spread your risks across a basket of assets. By not investing all your capital in one instrument, you can mitigate risks. If one asset experiences a loss, other ones will counter it with returns. Building a diversified portfolio is key to properly diversifying. For example: divide your capital to buy stocks, commodities, currencies, and cryptos so that if one fails to perform, others will counter it. This ensures a stable income without unnecessary losses in the long run.

Hedge

Forex options and ETFs are great hedging assets. Forex options let investors lock in an exchange rate for a future date, which is very useful if you expect volatility but want stability. Currency ETFs, on the other hand, track specific currencies or a basket of currencies and allow easy trading or protection without trading forex directly, but they are still risky.

Monitor the economic calendar

Economic calendar is a free online tool that aggregates important macroeconomic news data such as interest rate decisions, CPI, inflation, employment rates, central bank announcements and speeches, and other crucial information. By monitoring them, investors can always know when important news data will be released, and they can postpone their investment decisions to avoid volatile times and only invest after the main trend is determined.

The Canadian Dollar is on a slow decline. Should you save in euros or US dollars instead?

The Canadian dollar has been losing its value against the dollar this year. For Canadians, this raises a simple question: if your CAD is losing ground, is it better to move savings into euros or U.S. dollars, especially bonds, stocks, or a carry-trade strategy? Carry-trade strategy in this context means to borrow in CAD and invest it in the USA or the EU zone. This is a complex matter, and to understand where the CAD is, how attractive other currencies might be, we need to analyze these currencies more deeply. Below, we will walk you through the data, practical costs, and risks so you can reach a usable conclusion after reading this guide.

Quick snapshot – What the markets say right now

Recently, the Canadian dollar has hit multi-month lows due to weaker oil prices and a post-Fed (U.S. Federal Reserve) market reaction (which raised the rates, making the CAD weaker against the dollar). Canada’s central bank has cut its policy rate to 2.25%, while the Fed’s fund rate remains notably higher at about 3.75-4%. The ECB (European Central Bank) main interest rates are lower than the Fed’s and near the low-to-mid 2% range. While the Euro currency to USD rates remain mostly predictable, due to higher US bond yield rates, the EUR remains stronger, still. The U.S. 10-year Treasuries are around 4.1%, Canada’s 10-year near 3.2%, and Germany’s 10-year around 2.7%, meaning that today the USD-denominated bonds have the highest nominal yield among the three. As a result, the dollar seems much more attractive when it comes to bond yields and stocks.

Bonds – Which currency is the best for fixed income?

The short answer is: USD bonds. When it comes to nominal yield alone, US bonds beat almost all other competitors. U.S. government bond yields (10-year) are noticeably higher than Canadian and German/Eurozone bond yields right now. As a result, US bond buyers have more income potential than Canada and the EU. Euro-area core yields are lower, meaning they are paying less than the USA.

However, nominal yield does not mean it is guaranteed real return, and metrics like inflation, currency rates, and hedging costs can impact potential returns directly. If you buy USD bonds but the dollar falls against the CAD, currency losses will most likely wipe out the higher yield rate. If the Fed lowers its rates, it will make the dollar weaker against the CAD and EUR.

Another challenge is that, if you live and spend in Canada, you are using CAD, and when exchanging it for dollars, you get exposed to foreign currency rate risks, which must not be underestimated.

Stocks – Euro or dollar?

Both the EUR and USD have their advantages. USD has strong liquidity and strong long-term performance, while EUR equities offer valuation opportunities and recent relative strength.

Why USD?

The U.S. market remains the most liquid stock market with strong earnings for many tech and large companies. This makes USD stocks very attractive for long-term-oriented investors. S&P has been rising historically, and even after crashes, it often recovers its value relatively quickly.

Why EUR?

European indexes have performed well this year and in many cases cost less than their U.S. counterparts. While cheaper does not always mean better, these indexes still have some growth potential. Some major banks in the EU zone, together with industries, have recovered strongly with a recent focus on military manufacturing, making many EU stocks very attractive, together with local indexes.

However, here is a caveat: if you are using CAD daily and it loses its value against the euro, the returns from euro holdings might shrink, exposing you to greater currency risks.

Carry-trade analysis – Is it viable to borrow CAD and invest it in USD or EUR?

The basic promise of carry-trade is simple yet powerful: you borrow cheaper currency and invest it in currencies with higher yields. In our case, is it lucrative to borrow in CAD and invest in either EUR or USD? To answer this question, we need to look at numbers. BoC policy rate is 2.25%, Fed funds from 3.75%, U.S 10-yr is 4.1%, Canada 10-yr is 3.2%. If we deduct Canadian rates from the U.S. rates, we get around 1.8% positive before costs. So, in theory, it could be lucrative to invest CAD in USD assets using a carry trade. Since the ECB has around 2%, it is not profitable to use a carry-trade strategy for the euro.

The bottom line

While the CAD has been weakening lately, it is still not cheap enough to naively invest in USD or EUR. However, if you want a pure yield and can tolerate foreign exchange rate risks, USD bonds are more attractive today. When it comes to stocks, USD equities provide stable and liquid markets. If you want valuation potential and diversification, then euro equities have become more attractive this year. When it comes to carry-trade strategies, the USD remains more lucrative than the euro, but on paper, traders and investors should evaluate all the risks and costs before investing in any currency.

In the end, Canadians who have CAD for their daily costs should be careful when trying to get exposure to other markets. US bonds, US stocks, US carry-trade, and EU stocks remain attractive choices for experienced investors.

Why Reading Online Reviews Matters Before Making a Purchase

People usually pause before purchasing to read reviews from other customers. It’s become part of everyday online life, a quick way to see how something really performs before making a decision. According to the Pew Research Center, most internet users read reviews to get a better idea of what they’re buying. The feedback from actual users becomes more reliable than marketing statements because it comes from everyday consumers instead of sales-oriented corporate messages. 

Reading reviews also helps spot patterns. If the same comment, good or bad, appears again and again, it usually means there’s truth to it. People now use this collective feedback as their main method to evaluate online products and services for quality and reliability. 

When There Are Too Many Options, Reviews Narrow the Field

Shopping online can be overwhelming and a bit of an adventure. There are always more options than anyone needs, hundreds of gadgets, countless household tools, endless entertainment subscriptions. All listings present themselves as excellent value propositions with operational excellence, yet it remains a bit of a challenge when it comes to verifying which ones deliver actual results. 

Reviews become useful at this point. Real users provide information about product details, which marketing content fails to show, by sharing their experiences about delivery speed and setup ease and product durability after several months of use. The product details show its operational behavior when used in regular business activities. 

Users tend to begin with reviews. For instance, a tech product might have amazing packaging but fall short on battery life or integration. Maybe a new game or casino platform might sound promising, and reviews on trusted choices can confirm whether it includes flexible payment options, a wide content library, and responsive support. When feedback keeps mentioning strong points like clear instructions or helpful customer service, it shows consistency. The product or service delivers its expected results because customers have personally seen its performance. 

Reviews Build Faith Through Shared Experience

Reviews gain their strength from the emotional bonds which readers find with each other. Reading about someone else’s experience feels familiar, even if you don’t know them. It’s basic word-of-mouth marketing, like receiving recommendations from a neighbor who has already purchased the item you are considering. 

This shared experience has built an informal community of online voices. People rely less on what a brand claims and more on what other users notice. When different reviewers mention similar strengths or small frustrations, it adds authenticity. The story becomes more believable. 

Reviews show what other users have experienced, but they do not offer any guidance about what to do. This type of his collective info turns into an important part of how people build trust online. It’s a small thing, but it makes a big difference in how confident we feel about the choices we make.

Balanced Feedback Feels More Honest

A perfect score does not prove that something lacks any imperfections. A combination of positive and less-than-perfect feedback creates a more authentic impression. Small complaints about packaging or delivery delays make glowing reviews sound real. A recent study showed that participants answered honestly instead of trying to make their responses attractive to others. 

Most readers know that nothing works flawlessly all the time. People look for reviews which provide both positive and negative aspects because they want to find balanced opinions. Customers can establish realistic purchase expectations through combined information which they can apply before buying. Review systems maintain their value because reviewers maintain honesty in their assessments. 

Why Recency and Volume Matter

The best reviews and product ratings are the ones written recently. They reflect how a product or service performs right now, not how it worked a year ago. Things change, materials, delivery services, and even the way companies handle support.

A steady flow of new reviews suggests consistency. When lots of people share their experiences over time, patterns appear. Those patterns tell readers what’s typical, not just what’s possible. It’s the difference between one person’s lucky experience and a reliable average that others can count on.

Quantity matters too. Ten balanced reviews from this month will usually tell more than a single five-star comment from last summer. Together, recency and volume create a clear picture of reliability and quality without relying on assumptions.

Recognising Genuine Reviews

Not every review online is authentic, real, and written by a consumer. Some are written by automated accounts or people hired to post positive comments. Real feedback tends to sound natural and personal. It might mention something specific like the texture of a fabric, how easy the setup was, or whether support staff replied quickly.

Authentic reviews vary in tone and detail. Some are short, others long, some are full of small observations. That mix of styles feels human. On the other hand, copied or fake reviews usually repeat the same phrases or sound overly polished.

Many websites now try to identify and label suspicious posts, but readers can also help by paying attention to repetition, timing, and tone. A quick scan across different platforms usually reveals what’s genuine and what’s not.

Reading Smarter in the Online Marketplace

Reviews have become a solid foundation for how people make decisions online. They give an honest view of how something performs beyond what’s written on the label. Every comment, short or long, adds another piece to the puzzle.

More than that, reviews show how businesses handle problems, how quickly they respond, and whether they follow through on promises. They offer accountability in a world where shoppers and sellers rarely meet face to face.

Reading a handful of reviews won’t guarantee a perfect experience, but it provides helpful context. It shows what’s typical and helps people make choices with more confidence. In an online world full of noise, reviews remain one of the easiest and most reliable ways to learn from others.

With Einstein and Darwin

The above photo is not a real photo. Einstein and Darwin never met.

By David R. Topper A significant part of my adult intellectual life has been spent studying and teaching about the life and works of Albert Einstein. This led to my publishing various works about this fascinating, often frustrating man. Just as fervently, but not nearly to the same extreme, I’ve studied and taught about Charles Darwin. But I never published anything on him.

Since Einstein came after Darwin, the question often occurred to me as to whether Einstein ever read, thought, or wrote about Darwin. Indeed, I’ve gone as far as posing the following proposition to myself: Maybe, if Einstein had read and absorbed Darwin’s discovery about the astonishingly dynamical and unpredictable way the natural world works, then he may have been less rigid in his thoughts about the order and structure of the universe. In fact, I could go so far as to conclude that, if he had, then in 1916 he might not have made the erroneous assumption in his model of the cosmos, which he later called the “biggest blunder of my life” (quoted in Topper, p.165).  
But I’m getting ahead of my story and I need to start with some basic questions. Did Einstein know about Darwin, and if so, what? In searching through the literature on this possible juxtaposition of these two giants in their fields, as far as I can tell, I’m the first person seriously to pose this issue in some detail – which was a big surprise. It certainly gave me an incentive to pursue this diligently. Thus I did, and here is what I found – plus, at the very end, I add a zany speculation about the nature of the universe, as we know it today.
The names “Einstein” and “Darwin” are seldom juxtaposed, except in a general sense, such as when comparing Einstein’s theory of relativity with Darwin’s on evolution – as overall examples of major ideas in recent centuries. Going through all the indexes of the many dozen books on Einstein that I own, looking for “Darwin” – in the few times I found the name, the reference was always to a general comment about him as a scientist, with nothing about the content of his theory. At most, I found that Albert had read Darwin, which is important to know, but I found little information on what the theory meant to him or what he got out of it.
Hence, I began a journey to see if I could find more, since it seems that I’m the first ever to explore – or even ask – about Einstein and Darwin. My next question was: do we know when Albert was first exposed to Darwin’s theory, and what did he learn? The earliest time I found was during the school year 1895 to 1896, when he was in Aarau, Switzerland, taking remedial high school before enrolling in the Polytechnic in nearby Zurich. We know that the Swiss school he attended was very progressive and it taught Darwin’s theory of evolution. It’s worth quoting something he said much later, when looking back on those years:
“By its liberal spirit and by the austere earnestness of its teachers … this school made an unforgettable impression on me; by comparison with six years of schooling in an authoritarian German Gymnasium [i.e. High School]. … I became acutely aware how much an education directed toward freedom of action and responsibility is superior to an education resting on drill, imposed authority, and ambition (quoted in Ohanian, p.9).”
During his next four years in Zurich at the Polytechnic, we know that among the many physics and math books that Einstein read, he also read Darwin – but we don’t know the details (Pais, p.44). Thus, as we move into the 20th century, at least we can say that he knew something about Darwin’s theory.
My next source to explore was the Collected Papers of Einstein, which are at present up to May 1929, when Albert was age 50. Over all those years, there are only a few places where the name Darwin appears. There is a book review he wrote in 1917, where the author mentions Darwin. Next, is a letter from a colleague in 1918, who talks about Darwin’s theory in passing, while making comments on society and politics. The only place where Einstein himself talks about the content of the theory is in the Third Appendix to his popular book, Relativity: the Special and the General Theory, which he added around 1920. That’s all there is. Albert died in March 1955, so there are still 26 years to go for the Collected Papers, but I’m not optimistic that anything significant will surface therein. Yet, who knows?
Using what I have, let’s explore this topic further, beginning with this appendix. The title is: “The Experimental Confirmation of the General Theory of Relativity.” Einstein begins with a brief foray into epistemology in science: induction and deduction. As science progresses over time, the inductive accumulation of empirical data occasionally needs to be supplemented by deductive ideas logically based upon a few given axioms; and from this there emerges a “system of thought” or a “theory.” The justification for the very existence of the theory is the fact that it correlates with a range of observations (empirical data) and “it is just here that the ‘truth’ of the theory lies (Einstein, p. 124).” He puts the word ‘truth’ in quotes because, as is often the case, there may be several such theories competing for an explanation of the same data. The ultimate goal of this for him is, of course, the issue of his general theory of relativity to explain gravity, in competition with the old theory of Newton. But before he delves into that – which constitutes the rest of the Appendix – he makes this aside comment on biology.
“As an example, a case of general interest is available in the province of biology, in the Darwinian theory of the development of species by selection in the struggle for existence, and in the theory of development which is based on the hypothesis of the hereditary transmission of acquired characteristics (Einstein, p. 124).”
That’s it. As far as I know, that is the only direct statement about Darwin’s ideas that Einstein ever wrote. Let’s look closer at this, for we will need it later. First, I want to point out another way of putting this. Einstein is contrasting the difference between Charles Darwin’s random selection method of evolution, with Jean-Baptiste Lamarck’s developmental process, which had a predetermined direction or goal for the evolutionary process. Thus, Darwin’s “struggle for existence” revealed the dynamical nature of plants and animals as they change over a long time-period. I’m assuming that Einstein realized all this, along with the lack of a specific direction for the evolutionary process according to Darwin. I just wish Einstein had said more; but we go with what is given. Moreover, the stage has now been set for why I have raised the name of Darwin in the first place.
In 1915 Einstein published his landmark paper on the general theory of relativity, which was essentially an explanation of gravity. Whereas Newton had pictured gravity as an invisible attractive force between all the elements of matter throughout the universe (from rocks to planets and stars), Einstein pictured it as a four-dimensional curvature of space (or, more precisely, space-time) around all those elements. Although Einstein’s paper constitutes pages and pages of tensor calculus equations, the conceptual image is quite simple. A rock is not falling to earth by an invisible attractive power; rather, the rock is simply moving into a dimple in space.
 After completing this arduous task of many years, Einstein immediately wrote the popular account of the entire theory of relativity for the general reader, with a minimum of mathematics. In his Preface to the first edition, dated December 1916, he ends with this: “May the book bring some one a few happy hours of suggestive thought!” It was the Third Appendix to that work that I quoted above.
Next, he made a prediction. Still in 1916, from his general relativity theory, he wrote another paper, predicting the existence of gravitational waves. Over his lifetime such waves were never found, and in his latter years he doubted that they ever would be – since they are so infinitesimal in nature. But in 2015, almost exactly a century after their prediction, gravitational waves were detected by the clever design of a very big experimental apparatus that was necessary to find these minuscule waves. The three scientists who designed and did the experiment got the Nobel Prize two years later.   
Back to 1916, for Einstein was not yet done. The entire enterprise had triggered another thought, and yet another paper. It started with a question. If the space around all elements of matter is bent locally, what does this say about the universe as a whole? Thus, Einstein went back to those equations for locally bending space and – so to speak – he summed them up for the space of the entire universe. In doing so, he found that the resulting universe – unlike the infinite space of Newton and others after him – was finite, since all space curves back into itself. It was as if we were living on the surface of a four-dimensional sphere of finite size. This finite universe was okay with Albert; he saw it as just another discovery that he made.
Yet there was a problem: according to the equations, the whole thing was unstable, due to the gravitational attraction among all the elements of matter. Such a universe would slowly collapse – and that would not do. Surely, the universe was stable; and so, in order to save this theory – after all those years of gruelling work – he stabilized the equation by adding another term; this term symbolized another force, having an equal and opposite repulsive power that balanced the two, and hence stabilized the universe. He called it the cosmological constant. To him, this was another discovery; that is, it was just another constant in nature. All this he published in 1917, and it formed the basis of a new cosmology. Indeed, all modern cosmology goes back to these landmark papers on general relativity by Einstein. Over the next decade, there were a few challenges to his model; particularly around the cosmological constant. Einstein did not see all of them, but the ones he saw, he rejected – thus holding fast to a stable universe.
Also, around this time, Einstein had another bright idea. Since the first decade of the 20th century, when he published his first papers on relativity, he also published major papers on the parallel theory of the atomic constitution of matter; namely, the quantum theory. His other bright idea, which absorbed his scientific attention starting in the 1920s, was to unite the two (relativity and quantum) into a unified theory of everything. He eventually called it the “unified field theory,” and it became his key obsession for the rest of his life.
In the meantime, by the start of the 1930s, he was forced to reconsider his cosmological model. It began in the summer of 1930, when he received an honorary degree from Cambridge University, where he met Arthur Eddington – the astronomer who had led the solar eclipse experiments that proved Einstein’s relativity theory in 1919, by measuring the bending of light from a star around the sun, as predicted by Einstein. Eddington now was familiar with important results coming from American astronomers, such as the work of Edwin Hubble at the Mt. Wilson observatory near the California Institute of Technology (Caltech) – holding the largest telescope in the world at that time. The results, as Eddington interpreted them, meant that the universe was expanding. It was as if that four-dimensional sphere was a balloon being blown up. Since this model contained a force of expansion outward, then no cosmological constant was needed. The universe was, indeed, unstable – and as well, expanding over time.  
Serendipitously, at this time, Einstein was on his way to Caltech for three winter sojourns (1930-1933). While at Caltech on his first visit, he therefore had to abandon his commitment to the static model. He was quoted in the American press as saying that his old model was “smashed … like a hammer blow,” and he swung his arm with a fist while declaring this (Topper, p 174). Never again did he bring up the cosmological constant. In the early 1950s, when the topic arose in cosmology again, he was questioned about it: and, as mentioned before, he called the use of that constraint “the biggest blunder of my life.” (I should note here that in recent years it’s been discovered that this expansion of the universe is, in fact, accelerating. Hence, another repulsive force must be added, which today is called ‘dark energy’. Ironically, this may be seen as just another way of bringing back Einstein’s cosmological constant. Perhaps it wasn’t a mistake, after all.)
It’s important here to remember that Einstein’s extraordinary contributions to physics, ranging from his own theory of relativity to a wide range of topics in quantum physics, lasted from around 1905 into the mid-1920s. By then he became obsessed with his unified field theory, and essentially ignored all other important new fields, such as nuclear physics. Although popular culture likes to juxtapose an image of him with his halo of hair next to a mushroom cloud from a nuclear bomb – for example, the cover of Time magazine for July 1, 1946 – in fact, he made nary an iota of input to the actual development of that important branch of 20th century physics. This runs counter to what you may be told in popular accounts of Einstein’s life and work, such as on TV and in the movies. (Yes, I know about that little equation about energy and mass that Einstein is famous for. It was there in those early years of the quantum physics of subatomic particles. Nevertheless, it’s a very long haul from that seemingly innocent equation, through decades of work in nuclear physics, and then designing technological contraptions to making a bomb or any other applications for nuclear energy. All of which was done without Einstein. Incidentally, in that famous Time cover, E = mc2 is embedded in the mushroom cloud.)
More importantly, as quantum physics evolved into quantum mechanics around the mid-1930s, Einstein vehemently rejected the statistical nature of the subject. Although he himself, starting around 1905, had published many important papers using statistics within the quantum world, he interpreted it as a limit imposed by the experimental tools that we have in probing the subatomic world. To him the statistical features were not a part of the world itself, which is – at least, potentially – completely predictable. Yet by the 1930s, especially as expounded by his friend the Danish physicist Niels Bohr and others, the quantum mechanical interpretation of the statistical nature of the equations was that the underlying subatomic world itself was statistical in nature, and had no predetermined or predictable order. Only probabilistic statements can be made about that minuscule world – and that was its fundamental nature, according to quantum mechanics.
 Einstein would have none of this. To make an analogy that I believe he would like: consider the use of statistics in actuarial tables by insurance companies, in order to predict the behaviour of groups of people, since individual behaviour can’t be predicted. Using Bohr’s interpretation of statistics in quantum mechanics, there would be no real people – only probable people! However, for Einstein electrons (along with other subatomic particles), like people are real. And so, the fact that quantum mechanics must rely upon statistics to work, means that the theory is incomplete. The problem is with the theory, not the world. Indeed, he believed that one result of achieving his unified field theory someday, would be the deduction of a complete, predictable and real subatomic world. That was another reason to pursue his quest.
In the closest writing to an autobiography, which Einstein penned in 1946, he said this: “Beyond the self, there is this vast world, which exists independently of human beings, and that stands before us like a great, eternal riddle” (Topper, p.10, italics mine). Nonetheless, Bohr’s viewpoint prevailed amongst most physicists. Hence, Einstein fought a losing battle to the end of his life.          
 What all this shows is that throughout his life, the concepts of stability, predictability, and order were fundamental in Einstein’s picture of the universe – the way he believed his one equation for the unified field theory (if found!) would unite the worlds of relativity and quantum physics. He died in 1955 without finding this equation. Nevertheless, the quest continues, with myriad physicists today searching for, what they now call, a theory of everything.
Now back to cosmology. We now know – and by “now” I mean in only the last few years – that the universe is much more dynamical than it was ever imagined to be, even with all this expanding and accelerating going on. Stars group together as galaxies, and galaxies group together into larger clusters, due to their gravitational attractions. But – and this was realized with the help of the Hubble and now the James Webb telescopes – galaxies merge and interact in a process producing new galaxies. One might call it an internal dynamical change among the galaxies that we never knew about, until now. Closest to home, consider our Milky Way galaxy, where “we” – namely our solar system, with a star (our sun) at the centre – are near the outer edge. Being far from the black hole at the centre of our galaxy, it’s a rather quiet place (astronomically speaking) – and hence life was able to take hold and evolve into what we have today. This will go on until our sun runs its course. Our star is now almost halfway through its 10-billion-year cycle. In about 0.5 – 1.5 billion years, as it starts running out of hydrogen fuel for nuclear fusion, it will expand into a “red giant” that will encompass the orbits of Mercury, Venus, and our Earth – and hence all life as we know it will end. (Unless, of course, humans, with their nuclear weapons, hasten that event.) After that, the sun will collapse into a cold “white dwarf.”
Independently of all this, and on a larger scale, our Milky Way is part of a group of galaxies, the largest being the so-called Andromeda Nebulae, visible as a smudge to the naked eye. Due to gravity, these two galaxies are on a collision course, moving closer at the rate of 110 kilometers per second. They will meet in about 3.5 billion years, long after life has ended here. At the same time, a much smaller galaxy, M33 (also called the Triangulum Galaxy) will also take part, along with the Large Magellanic Cloud (another nearby small galaxy), which may join in on this merger. What happens next is not clear, since we need much more information from the Hubble and the James Webb telescopes. Even so, we will never know if any prediction is true or not, since no humans will be around to see all this happen!
Nonetheless, we do know a lot about such an event. Importantly, I need to clarify what we mean by a collision of galaxies. Or, maybe better said: what we don’t mean. There will be no fireworks, like clashing and exploding stars. To understand this, we must realize this fact: although from a huge distance, any galaxy looks like a compact mass of stars, in reality the individual stars are extremely far apart. As an example, consider our sun and the closest star, Proxima Centauri, which is about 4.2 light-years away. If the sun were a ping-pong ball, Proxima Centauri would be a pea about 1100 kilometres away. And so it goes throughout our galaxy and beyond, with all the other galaxies. In short, the universe is mainly empty space – strange as that may seem. Accordingly, when galaxies merge and form larger ones, there are no fireworks – just a different arrangement of the way stars group together. As for our Milky Way and Andromeda collision – along with the smaller ones – they may just pass through each other, and go on their astronomical ways. Or not. There are several possible groupings that may take place among these merging galaxies in the distant future. All this may be seen by some sentient beings on a planet in orbit around a star, both of optimum size, and in a quiet place similar to us in the Milky Way, such that a life-form evolved to our state of self-consciousness. What would they make of all this?
Now, bringing all this back to the present, and recent past: with Einstein & Darwin. So, here’s my bright idea. Thanks especially to the James Webb space telescope, and thus having this most recent information about how dynamical the universe really is – and, thankfully, not having an obsession with order and stasis – I find myself speculating about the process of galaxies merging and interacting, thus giving rise to new dominant ones and eliminating the old. As such, I picture this as an evolutionary process of survival and extinction – Darwinian in nature. A struggle for existence among the galaxies. A random process producing new galaxies throughout the universe, with no predetermined direction or goal. As such, it’s parallel to Darwin’s notion of natural selection. But now writ large (very large!), to encompass the entire universe and everything in it.
This, at least, is what all this information is telling me. Makes sense, I say.
What would Einstein say? Or Darwin?  What do you think?


As a kind of footnote to this essay, I want to point this out: I know where most of Einstein’s commitment to the structured and ordered universe came from. It was his adulation of the Jewish philosopher Baruch Spinoza. I too read Spinoza’s Ethics, and was in awe of the depth of logic entailed in this incredible but difficult work. Unlike all other philosophers that Einstein read – and he read many; remember, he was educated in a 19th century German system – he never critiqued Spinoza. Rather, he absorbed the arguments from the Ethics for his views of the world, as well as for his theology. However, I, with my understanding of history, am able to see how Spinoza’s book was squarely centered in the world-view of the 17th century – not the present world that I live in. Too bad Albert didn’t do the same.
