So far this is the most comprehensive breakdown of the quantum space part I've seen, but I still wish someone that understood what was going on could breakdown what the 2nd orange guy (I guess wise animation) did when he tapped the einstein rosen bridge to select a different thing before going through it and leaving the original animation with the 3rd one. I'm tired of looking though, but you definitely deserve to have your video seen by more people.

Always love the explanations. Good job!

It might be touching on the Bootstrap Paradox at the end. Or at least a type of open time loop where the events infinitely repeat but with the next generation of characters. Orange learned everything from a future version of himself. Then we see his past version emerge the same why he did. The loop then repeats.

Nice explanation overall, I spotted some iaccuracies though. a) gravity assist isn't as simple as described by you. b) the rod isn't metallic, it's ferromagnetic. c) you missed the nod to the different types of string theories ar the very end. (Orange sliding on the hyperbolic space befor disappearing)

Thanks for highlighting

A more thorough version of 5:36 is the bidirectional reflectance distribution function. I became familiar with it to simulate realistic lighting in computer graphics. Helps in avoiding inaccuracies like specular highlights that are too bright (or else it's like you're creating extra energy out of nothing).

Thx for all of this

May there be an error in the video? 1) Magnetic rings should not accelerate the rocket, since, after going through it, the rocket should be pulled backwards, leaving scape velocity (the initial velocity) as the final velocity Also, the surface is not frictionless (mu=0.1). This is important because otherwise he could not increase its velocity by throwing the ball since it would break linear momentum conservation Small comentary on the solenoid: Solenoids (AKA coils) don't transform currents into magnetic fields, which then can get converted into motion. However, they do not need to be ferromagnetic or magnetised for this, and the animation does not show any flow of current (though it mentions the relation between current, turns and the magnetic field))

I've been seeing other reacts/explains of this video, as the first time I watched I was also skeptical about the magnet Canon. However after watch videos, and reading other comments, I think it is (theoretically) possible because of the initial velocity and thrust. If the rocket were to begin at rest, yes it would oscillate. However the rocket is coming in with a velocity, acceleration, and most importantly momentum. In the end, my stance is that he would gain some speed as his time in the red side would be greater than the time in the blue side

0:33 Isn't Velocity Defined As Rate Of Change of "Displacement" Instead Of Distance?

Direction is understood

I think u understood swing bys wrong. it's not the gravity of the planet that gives you speed, but actually you steal it's orbital velocity around the sun. you need a third reference frame to make sense of it (the solar system reference frame). Also since TSC is always accelerating, he's not on a geodesic, he's doing powered swing bys, making use of the oberth effect.

In general relativity, an accelerating body can follow a curved path, which corresponds to a geodesic in curved spacetime. This is described by the equivalence principle, where acceleration and gravity are indistinguishable locally

@@boomaletslearntogether That's not the point. If you just fall into a gravity well, you'll emerge at the same velocity you fell into it. If you enter a moving gravity well, you can gain some momentum by slowing down, the moving well. The impulse you have, that is perpendicular to the moving well is affected by the acelleration experienced towards the center of mass. The impulse changes direction. In the frame of reference of the planet the velocity of the ship dosen't change. It's following a geodesic after all. In the solar systems reference frame, the velocity of the planet has been added to the velocity of the spaceship.

I love the animation. But in the subtitles, something was botching the terms for me, like eg the name Penrose or the word quantum, as if they had been warped by the extreme pysical conditions.

2:16 Pretty sure this doesn't work at all. If there's no friction, you can't just throw an object and then use it to pull yourself forward. Those two will cancel out.

@danielwenzel3877

When throwing a ball on a string and the string becomes taught, some amount of force is exerted onto both the ball, and you. We don't move because we're standing on a surface with friction. TSC since he's on a frictionless surface, will begin moving; though very slowly. That's also why you see TSC throwing the ball multiple times; to gain some credible velocity. Also, TSC would begin moving regardless if the ball was pulling him, or if he was pulling the ball; which in this case, the former is true.

@@alexleavitt7590 That is not how it works. It's not like the ball has rotational momentum instead of linear momentum when he is spinning it. It always has linear momentum. If he started motionless then started spinning it, the horizontal component of the linear momuntum of the ball would always cancel out with his own horizontal linear momentum. He would basically be wiggling back and forth slightly while spinning it. So when letting go of the ball while it is moving forward, he would be moving backwards with equal momentm. Then when the string goes taught, they cancel out and he is motionless again.

In 6:30, I don't think his hat give much difference. It's more of the direction of his rocket that changed the rocket orbit. At first, TSC pointed the rocket up or vertical (6:32), thus making the orbit smaller and guarantees impact as the star's gravity is too strong. Instead, at 6:40, TSC pointed the rocket horizontally to make the orbit wider-- enough to encircle the star once without hitting it. No need to fight gravity full-on. His increasing velocity helps too. Though, based on other comments here, I am unsure if the planet gravity assists are the same as the assist from the star. "Oberth maneuver", is what my understanding goes so far. I'll leave that to smarter people to enlighten. It is also easy to miss the change of the rocket's direction as the hat and cowboy act took the spotlight.

Very cool explanation

@boomaletslearntogether

We move forward because as we push the Earth backward, it reacts by pushing us in the opposite direction, following Newton's 3rd law. This principle is evident in the movement of a boat with its paddle-by pushing water backward, the water, in turn, propels the boat forward. Similarly, swimmers move forward by pushing against the water.

my best guess, if you're well centered through the magnet, before the rocket reaches the center of the magnet, it gets pulled in, the moment the rocket reaches the center and moves past it, the current induction of the magnet onto the rocket turns into a repulsion one, effectively pushing it away from it at a higher velocity. the best comparison to an irl application would be a railgun, since the projectile follows the same principles as the one shown here between the rocket and the magnets
