Comments by "Lepi Doptera" (@lepidoptera9337) on "Do we need a Theory of Everything?" video.
I looked at her publication record and it is pretty lame for the most part, at least recently. She publishes fluff pieces about the foundations of quantum mechanics, which really nobody cares about and "yet another dark matter model" kind of stuff. In other words... she does exactly what she accuses other theoretical physicists of doing. I don't blame her for that... she doesn't have the data, either. She is basically spinning her wheels until a group of experimentalists will find the next big clue.

They had a century of spectral data to test QM with. It didn't come out of thin air. Quite the contrary. It was born out of an abundance of extremely complex and hard to understand experimental data.

Mostly so that the average high school student doesn't commit suicide. Kids have a breaking point and most of them break when you ask them to digest material that is even hard on adults. Of course, if you want to torture kids in school even more, why don't you ask them to translate Homer's works from Greek into perfect English hexameter in third grade. I am sure you will find half a dozen third graders in the country who can. The rest will simply walk out on you mentally and they will start taking drugs to forget what grandiose failures they are. What do you think?

Einstein knew what the answer was (it had been known since, at least, 1887). What he didn't know was what consequences that answer had for classical mechanics and why it made more sense to abandon classical mechanics than electrodynamics. That all physics was relative was, by the way, already known to Galileo. He pre-empted Einstein's elevator Gedanken-experiment with a similar but logically equivalent example of the physics inside of a moving ship by two and a half centuries. What he didn't know and what not even Newton and his successors realized is that the principle of relativity, when applied to coordinate systems, has two algebraic solutions. One solution are the Galileo transformations, the other the Lorentz transformations. Anybody with sufficient algebraic knowledge (that's basically every mathematician since roughly Euler or so) could have taken relativity as a principle and they could have scribbled down the derivation of the Lorentz transformations in less than one page of high school algebra. That nobody did is one of the great mysteries of physics and mathematics, IMHO.

God did it doesn't explain anything.

Yes, even a monkey can type an incomplete formula on a keyboard. An actual human being might be able to type the complete one. Please try to act like a human being in the future.

The problem with asking for a unification of the known three forces is that it's not clear whether they are all the forces there are. We have absolutely no idea what happens at 10, let alone 100TeV.

That's the idea, except that Einstein had clues from nature to work with, our current theoretical physicists have absolutely nothing.

@justinwhite368 You were the one who got started on Einstein. Must be a fixation of yours. :-)

@justinwhite368 Fun is never silly. I am having fun, my friend.
