I know an object can be stationary relative to another, but is there anything absolutely stationary in the universe? Or is space itself expanding and thus nothing is stationary?
In: Physics
Also… “Objects” are not stationary either. Objects are made of atoms that have electrons fuzzing around without even clearly defined position, plus, if you buy into string theory, “everything” is bunch of vibrating string-like things.
Only way to be truly stationary is *maybe* to have literally nothing to be relative to. A single dot with no dimensions in endless nothing. Perhaps. If that dot was everything that exists, a whole reality. Or maybe you could define it from other, macro side – while nothing is stationary, array of “everything” can be stationary. Since everything consists of everything so there’s nothing to be relatively in motion to
