Animating Einstein's Special Relativity (Train Tunnel Paradox)

[adb]

Simultaneity is also relative. That the 2 doors are closed at the same time in the tunnel frame of reference doesn't mean that they will also be closed at the same time in the train frame of reference.

I think we can use relativity of simultaneity here. Simultaneity of time Lorentz transformation equations

Einstein said speed of light is same in all frame of references with respect to the observer the very important and most crucial thing

Super shirt!!! And super short!!! 😂 Love your contents!!

[trishlangford]

Loved this on his channel a while back. Brilliant and exciting.😊

[mweave]

Nice video! I love the speed of light circles.

[chrissy]

Trains can't travel at the speed of light.They are mostly late.

The second wave is slow to propagate. It needs to "speed up" to hit the third deflection. But really it is the quantization that changes. The error, is in perspective.

[aminnifzi]

Why is everyone in the scientific community saying that the speed of light is same in all reference frames? Einstein never said that, neither did he wrote it ever.

[boitjie]

What if I didn't open the doors again?
How would the train expand again?
How would that look like from the trains perspective?

Had a homework question on this problem last quarter lol

[sajalrastogi]

I will come here tomorrow after my brain resets

Train front side Electro magnetic wave wave length is less then train end side so door detector detect first right side door close early then left side .
Now at train refrence first right side door close and then left side door close .
But at platform refrance refrence both door close same time.

[MrMoose]

The real issue here is it’s just perception. You will never shrink the train to fit. 😂

[innovation_pirates]

If u ask me, make the whole train go in the speed of light, until some meters before the entry, when, just use breaks on the 1st row of wheels.

[crazieeez]

All speed is relative to the speed of light. Speed is not relative to each other.

The speed of light is the speed of casualty in flat spacetime which is special relativity.

However, the speed of light is NOT the speed of casualty in curved spacetime. If you live close to a black hole and do physics, you will find speed of light and speed of casualty differs.

[Tryhad]

The biggest issue of this experiment is setting up sensors which are faster than speed of light.

[kaleijuka]

All inertia reference frame observers are equally valid*

[jayjain]

I think relativity is one of those things I will never understand 😅
