When we think about teleportation, there’s always someone talking about how you should take into account the earth and the sun moving through space. Let’s step back a little (not so much) what if the galaxy we’re currently in is rotating really really fast around another, bigger, still unknown, spacial object?
Yeah but since the speed of light is always relative to a reference frame, wouldn’t the distance to the beginning of the universe depend on the frame you use to measure it?
