Physics, Astronomy & Cosmology / Re: Why does vacuum affect frames of reference?
« on: 20/02/2024 09:22:09 »
Since a vacuum contains nothing (by definition) it has no reference points and hence no preferred direction. Therefore it is isotropic and whatever happens in a vacuum will happen in exactly the same way in all directions.
Same would apply to a bullet in vacuo, in the absence of gravity.
So the answer is that vacuum isn't a frame of reference, but anything else is!
