The Man Who Corrected Einstein

This video is about how Russian physicist Aleksandr Fridman corrected Albert Einstein about the expansion of the universe. Einstein thought that general relativity implied that space had to be static and unchanging, but he had made a technical error regarding the differentiation of the metric (in particular, I believe he mistook the determinant of the metric for a scalar rather than a tensor density of weight 2). Friedmann didn't make this differential geometric mistake, and the cosmologies he found from the Einstein Equations were more varied in their properties - they could be expanding, or contracting, or (with the cosmological constant), static.

    This is incorrect: Einstein realized the equations of General Relativity implied an expanding universe. He added the "cosmological constant" to the equations of GR to obtain the solution of a static universe, which is what everyone thought was the case, and at the time there was no reason to assume otherwise. The observations WERE NOT good enough to determine the universe was expanding -- those came in the 1920's, or about a decade later. Friedman simply obtained the solutions Einstein had obtained and did not make any extra assumptions. Einstein then considered adding the cosmological constant his "biggest blunder." You're misrepresenting the development of the ideas about cosmology that stemmed from GR.

    My senior physics capstone project in undergrad was on quantum locality and contextuality, particularly looking at various proofs and disproofs of Bell's Theorem. Which was very confusing as an undergrad, trying not only to learn the proper math and physics behind what I was studying but carefully combing through the logic of the proofs and disproofs to figure out what was right or wrong. My advisor thought it would be an interesting project because there's a guy who is regarded by most in the field as a quack who is very adamant about his disproofs. Even navigating the academic politics of that was tricky. In some ways, I kinda wish I saved that for grad school instead but I digress. It gave me an interesting perspective on what is true and false in physics. And it was a major exercise in trying to distance myself from both the bias to agree with Einstein and the bias to disagree with the critic. Everyone wants to agree with Einstein because he came up with what is now a critical part of physics. But as you say, even he was human. He made mistakes. We all do. In that way, I think the best scientists among us are the level-headed ones with enough empathy to clearly separate correctness from popular biases. I just wish academia could be less political. And physics, especially, to be less egotistical. It is a plague.

    Sadly it's not just a critic on Physics, but on society as a whole I'm afraid. The issue is that so much of our economic position in life is tied to perception, rather then reality. And when a guy who throws a ball with a nice spiral can make literally 100-1000x times the salary of even the most successful physicists, it's crazy what society deems as worthy of praise, and the heaping of riches, and fame, and vs some brilliant breakthrough in math, or physics that come often barely make the news. I remember it was said that people who have so little power, when they find themselves suddenly with power, find it very seductive, because they have never had that before in their lives. Same with money, people who have never had money before, have no idea of what to do when they get money, and sometimes can lose all their money because of it. Society is crazy, we train physicists to learn the math, but what about dealing with success, or failure. So now people are going to try to choose to work on things they feel like will open those doors for them, etc, rather then what the physics is telling them they should investigate. That's the thing about Einstein, he was basically completely outside the academic circles, so he investigated what interested him, not what his graduate advisor told him to do... he had to do it all on his own, and that in many ways I am sure is why he was so successful. If Einstein was trapped in the present day university publish or perish environment, I have no doubt it would have likely crippled his output...

But the notion of a cosmological "constant" started to appear before any observation of accelerated expansion. It was brought back even before, as quantum field theory was developed and slowly matured from the 50's and onward.

    Most brains start shrinking almost as soon as they’re done growing-around age 25. it’s subtle at first, and if you live right or have good genes, the process is slower, but it accelerates over time. younger people just have more pliant minds on average. interesting side note: on autopsy, it was shown that Einstein’s brain, even aged over 70 years, showed many of the characteristics of a younger brain. but there’s a reason his most outlandishly creative contributions to science came in his early 20s. ditto Newton.

    Lone Starr I think you missed the argument entirely; the original comment never made any claims that this gives any confirmation/proof/etc for a given claim. It merely asserts a normative approach to (what I would call) skepticism...it’s essentially the mechanism of falsificationism (that we can only ever have certainty about falsities, not of truth...we can rule out erroneous solutions with certainty, but there is no way to confirm any a posteriori knowledge claims) Further, I think you’re conflating those two categories of knowledge...a posteriori and a priori. Never mind the finer points that still trouble some philosophers (as to whether math/logic is a priori or not); there is no proof of any a posteriori knowledge that can be offered in the way you’re seeming to demand...there is no formal proof for the earth being the third planet from our sun; it just so happens to be the case, but there is no proof one could put forth that would necessitate it (after all, that is what a proof is; if the premises are true, then it necessitates the truth of the conclusion as well, but there’s absolutely no reason why this planet had to be where it is...the earth could well have been where Pluto is, and while life would likely be non existent were that the case, it’s still possible... ) Similarly, how does one make a proof for gravity? It is an empirical fact that we live in a universe in which the effects of gravitational interactions are observed (I hesitate to say gravity “exists” to refrain from opening a giant can of metaphysical worms), but a proof of gravity’s existence would either need to rely on observation (in which case, one needs to argue that something other than purely deductive reasoning CAN lead to necessarily true conclusions) or else would need to demonstrate that gravity is a necessary component of reality (that it is an impossibility for gravity to not “exist”).

    Vilim Lendvaj Arguably impossible; there have been several attempts (of varying success) to extend Gödel’s incompleteness theorems to all systems of axiomatic logic, and it seems reasonable to suspect this to be a valid application of Gödel’s reasoning in his argument against arithmetic-based axiomatic systems...essentially, this (generalization of Gödel’s argument) would argue that there can never be an axiomatic system which is both consistent and complete, simultaneously. A quick argument is as follows: Assume you can map every single statement to a single truth value (one to one); also assume that you have a complete and consistent system of statements and axioms. You have a dilemma when you encounter the following statement: “This statement is not provable in this system” If the statement is false, then that means it IS provable, but a provable statement must be true in any consistent system, because a proof demonstrates the necessity of a conclusion. (You might be inclined to think that you can prove things don’t exist, but you’re not proving a falsehood, you’re proving the negation of a falsehood as being true...it sounds like a trivial distinction, but remember, we are currently in the domain of philosophy and in philosophy this is NOT a trivial distinction. The important point to note is that FOR ANY proof, the conclusion is always true if the premises are true, EVEN IF the conclusion is a “negative” claim, like “therefore the square root of two cannot be a rational number”). So because any provable statement must have a true conclusion, then we know it cannot be false...but that means it must be true...that this statement cannot be proven by the axioms, but if the statement cannot be proven by the axioms, then we cannot have a complete system, for there exists some statement which exists outside the space spanned by the axioms. Thus we cannot have a complete and consistent system; that is, there is no minimum set of axioms which can be sufficient to account for all possible knowledge (there are some truths which can only be derived if we expand our set of axioms). Gödel proved this for mathematics last century...it may well apply to all formal logic, and if it does, then to say it’s hard to validate the soundness of an argument is an ENORMOUS understatement (and may be impossible depending on how we chose to define things like knowledge and justification...if we are required to be justified in accepting every entailment of all our beliefs, it’s simply impossible for us to know whether an argument is sound at all)

    Usually love your stuff, but this is a really rough interpretation of the history here. In Historian Walter Issacson's Einstein: His Life and Universe (a very well sourced academic biography written with Einstein's own notebooks) The generation of the Cosmological constant came about because Einstein knew the equations he generated caused expansion/contraction and the current experimental picture said that wasn't the case. (Chapter 11 pg254 of the kindle version) His blunder was not sticking to his original mathematical guns and predicting a non-static universe, because he literally had it. Not salt about a bad derivative or whatever

Hence some gentle reframing was employed.

    That isn't necessarily at odds with the explanation here. This video says that the equations only gave a static universe if it was empty (which it obviously isn't), and the cosmological constant was added so it could be flat and still contain mass. And it's worth noting it isn't exactly a straight up mistake, but he only found one solution to an equation with multiple solutions, and didn't look any further because it was the solution he was expecting.

    Einstein didn't make a mistake though. Friedman gave three solutions. The one in question is just one of those selected to fit popular cosmology. That selection ignores the mechanism of light, Huygens-Fresnel, and what Hubble's law actually did (used depth of the field to recover focus to measure distance). Redshift happens with distribution to the field, not just motion. If you read the reports close you see a pattern of confirmation bias, where they literally contract the numbers to confirm their expectations. The Deep Fields should be your big clue the modern cosmology is BS. Big bangs work, but only by their original design on a galactic level.

    @Vesui Well if you ask me, most of the daily challenges are more challenging and in depth than the math fundamental course. And besides that was a joke. If I had wanted to criticize, I would have phrased the comment differently.

    A true Scientist is always happy to be proven wrong, because he learned something new. I don't think Einstein was egoistic, he was probably happy that his Equations did in-fact predict the expansion of the universe. I think he was probably mad at himself for failing to realize it earlier.

    That's a total lie. Anyone who says that simply wants you to believe in scientific method, and it is indeed designed to fight against that exact human flaw. But scientists themselves can be as petty and butt hurt as any other people. In fact, pettiness and butt hurt are what often drives scientists to spend decades trying to prove that they are right and everyone else is wrong. And they sometimes succeed, sometimes posthumously. But oftentimes they do not, and the time they spend trying to prove themselves right is completely wasted.

    I remember when I took a vector analysis seminar my senior year of college a decade ago and it was terribly technical. It’s hard morphing objects from Algebra 2 and Analysis into spaces that don’t translate them well because of the conditions of the spaces themselves. It’s no wonder that we have a litany of names for particular spaces that are bounded by certain conditions and their particular diffeo-operators. Banach spaces, Hilbert spaces, Minkowski spaces. The list continues
