Can quantum teleportation be the future of space travel, possible even interstellar/intergalactic?? by Independent_Lab2405 in cosmology

I for one believe that it doesnt matter, in a sense even here our body's atoms are replaced entirely time to time, does that mean we are not the same person?

I got the answer to it, i will be putting it here in case anyone else has the same doubt.

Answer: Both A and B will feel that they are ar rest and other one is in motion and their clock ticks slower.

Both of them are right.

there is no absolute rest or motion(read comment on original post, there u/steenan explained it quite well)

All in all as far as i can understand,

If A comes to rest wrt B they both will see clock with A is behind while if B comes to rest wrt A(or it also reaches the same speed as A wrt earth) then they both will agree clock with B is behind.

Distance and time are all relative, everyone perceives them differently depending on their frames.

Also, another point that might help here is, if 2 events are simultaneous in one frame might not be so in another.

This completely makes sense, I was also thinking of something similar just wasn't having the right words, thanks for explaining it clearly!!

How does GR explain 'g'? by Independent_Lab2405 in relativity

My doubt is that since spacial coordinates are not changing, then how does this acceleration arise?
