Einstein's Biggest Blunder

Einstein's theory of general relativity was not always the concise, elegant equation we know today. Einstein needed a "fudge factor" to conform his theory to accepted conventions of the day. It wasn't until Hubble made a grand discovery that Einstein's equation regained i's simple beauty.

"...I thought I made a mistake, once, but I was wrong...."

No Einstein video is complete without a train, isn't it?

[grangermigel]

I wonder what Einstein would be if he had the technology we have now. He must be so OP.

That is the first realistic visual of the warping of spacetime I have seen. Much better than a ball on some stretched 2d plane. I have wondered for years why, with the computer tech. We have you only see a ball warping 2d space. What are we, flatlanders!?

The biggest blunder in Einstein's life was that he thought, he made a blunder. That's how awesome Einstein was. - Neil Degrasse Tyson

Universe: ”You fool! You fell victim to one of the classic blunders!”

Einstein: "Well yes, but actually no”

Good representation of space-time fabric. I've only seen ppl calling it 4D fabric while showing a 2D sheet. You guys have shown it perfectly.

In 2019, Scientists had for the first time were able to photograph the black hole, as Einstein predicted, as per his theory of relativity.

I knew that this video will be about the cosmological constant, just after i saw the tilte. But, you see when Einstien makes a mistake, it turns out to be correct! latest research shows that a cosmological constant is needed to account the effects of dark energy.

Edit: dark energy.

I thought the ridicule of Neil Bohrs over quantum entanglement and his refusal to accept that Bohrs was right was worse, as hear he is correcting himself publicly to show how nice he is.

Universe: *"Ha ha you fool, you fell victim to one of the classic blunders"*

[proximacentauri]

I really love how he pretty much saw the future of science and it was so weird to him that he thought it was a mistake.

It was indeed a blunder, especially since time as we know it would not work in a static universe.

If we consider an extremely simple static universe defined by a small static space and a particle moving around in this small space as time passes by. It obviously can't move to a region outside of the defined static space since that would increase the space and thus the universe. This very simple could be represented by a simple finite state space, and a state of that universe would be described by the position, orientation, direction and velocity of it's one and only particle.

But since the total energy of an isolated physical system is preserved, what exactly stops such a simple universe from becoming the same state over and over again? Nothing stops it from doing that, in fact it is inevitable that ever so often as time passes (if you could even say that about such a static system) the particle will have the same position, the same orientation, the same direction and the same velocity as it already had in a previous state.

So how could you even begin to talk about time in such a universe, when you cannot clearly distinguish one moment in time from a different identical moment in time? Well you definitely can't talk about time passing in the same unidirectional manner as it does in our universe, where time seems to flow from the past through the present and into the future, rather you would have to talk about time as some weird thing that goes back to the past ever so often and into the future ever so often, or in other words you can't really distinguish what is past and what is future.

Our non-static expanding universe on the other hand, can never again be in the same state as it was somewhere in the past, because it is expanding and it would have to shrink in order to go back to a state of the past. So any future state of our universe is an entirely new and unique state that will only ever happen once in the lifetime of our universe even if that lifetime is infinite, and this is what makes time as we know it and especially the flow of time from past, through present and into the future possible.

Einstein: Ops I blundered.
Hubble: no, u.

Imagine how cool it must have been to be the first person in history to know that your galaxy is just one of many

[theboxingbiker]

Americans always want to claim every achievement. It was george lemaitre who first proposed the expansion of "universe was expanding". edwin hubble just confirmed what Lematre had proven theoretically before him. Look it up.

The best graphic of space time bending ever shown..

Fudge factor! I'm no scientist but I use this in real life equations

[bigh]

Einstein just needed maths to prove the universe expansion Hubble needed the telescope

Thanks for showing the planetary body in 3 or rather 4 d space. So many times it is shown incorrectly.
