It's a pity that they didn't show Maxwell's equations. They would perfectly fit there when he turns on a flashlight

One more slight inaccuracy, at 9:44 when TSC jumps off the (still accelerating) rocket to get the magnet the rocket should just keep accelerating and leave him behind. We know the rocket is still accelerating because bright exhaust is still being produced, very slight error but one which almost nobody caught

Eh, if that was what happened, TSC would just be floating into space forever. Not a good ending for a video, like what they made later.

So far the best explanation I stumbled upon! Most of the reactions I skimmed through seemed to just name the principles. The spinning rope to linear momentum got me the most confused. I'm guessing how ever you twist the equations, the whole system momentum must be conserved even if TSC is able to generate angular momentum by doing work. I'm unsure if having the platform or the 0.1 friction makes it any more plausible.

There are two flaws in and around 10:59 : Firstly, you can’t create a magnetic field with solely a solenoid without inducing current through the solenoid. No electricity, no electromagnet. Secondly when TSC’s rocket’s South Pole is attracted to the ring’s North Pole, it creates acceleration and that’s all fine and dandy up until the rocket leaves the ring, where the rocket’s North Pole (rear) gets attracted to the ring’s South Pole (the side just behind the rocket) which decelerates the rocket. You won’t be able to achieve 0.8c this way.

Would be more accurate if he removed a battery from the flashlight and power a solenoid with it

At 3:50, while I also considered the conservation of linear momentum as a problem, that would only be an issue if u=0, which it isn't, since then the planet also becomes part of the system.

@ron与数学 11 ай бұрын

Great catch. The fact that TSC skis smoothly indicate that mu is indeed 0. Anyway, sometimes you have to sacrifice a little bit rigor for the story. It's all good.

Hella detailed than the first version, though i think the moment TSC enters the quantum world in 18:00, floating particle out of nothing is a reference to virtual particle as he is now small enough to manipulate strings (directly means manipulating particle)

@dreamcastgh0st477 11 ай бұрын

okay, so about the 'problem' at 3:49: it isn't actually a problem that he moves forward when he throws the ball. it's true that it seems like there should be zero net force, but that's only true in the absence of external energy provided to the system. as a hypothetical, imagine he was holding a jet engine, and activated it-- of course he'd move, since there's external energy being provided, in the form of the jet engine's fuel having chemical bonds which are broken down to get the energy. this is the same thing, but it's not a jet engine burning fuel-- the energy comes from TSC, in the form of sugars in his body or whatever breaking down, providing external energy. as for the momentum-- while the friction is low, it's not zero. i imagine that what would happen is, since his velocity is much lower than the ball's, and since he's in contact with the ground, his leftward momentum would be dissipated due to friction much faster, making it so that the rightward momentum of the ball would then transfer back to him, providing an overall rightward motion.

@ron与数学 11 ай бұрын

Hmm, thanks for your input. 1. Energy conservation is one thing but momentum conservation is another thing. You can have huge burst of energy of the "whole system" without changing momentum at all. 2. Regardless of the friction coefficient, considering the system as a whole, no external force causes momentum change. Think about this way... When the ball flys out to the right, there must be a "force" to "push" it out, why didn't this force push TSC leftwards? However, I do love your idea and I think it practically may work. When it snows in my place, I will do a real experiment on ice.

My personal theorem to life is that everything has been done before, that we can only experience once per parallel universe. Everything we're experiencing now has been experienced before and will be experienced in the future. Surprised you didn't mention the parallel universe and current universe when it came to explanation of the future and past. In fact, I'm surprised the original video didn't go into parallel universes. Steins;Gate would have been a prime example of it.
