suppose two rockets with a passenger are nearing speed of light velocities and are going opposite directions. Relative to eachother one rocket will seem stationary while the other rocket will look like it’s going almost twice the speed of light. What do both passengers see?

Question

I can’t wrap my head around it. But maybe it might be a very silly question with a simple answer.

In: Physics

Answer 1

It really depends on how the physics of the particular light speed travel your ship is capable of works. Assuming all the particles within the ship also accelerate along with it, but the particles outside don’t then whatever you’re traveling away from would just disappear instantly into the vanishing point.
