I Have Finally Made A Time Machine…Or Not [Comic]

I had a lengthy Facebook discussion with some of my friends from physics regarding this. The conclusion was that this comic assumes that there are absolute spatial coordinates which are sun-centric. However, in reality, the (more or less) inertial frame of the Earth is no less absolute than the sun-centric system, so there is no reason to assume that you wouldn’t reappear in the frame you left (i.e. the Earth’s), rather than moving to a new one (which is the sun-centric frame).

Basically, the comic assumes absolute space, which is incorrect according to Galilean relativity and Einstein’s relativity. Boom.
