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
nothing is technically stationary anywhere if you remove the qualification of “in relation to ___” because you can always expand the frame of reference to a point where a “stationary” object is no longer stationary.
eg. A plane on a tarmac is stationary. but the earth is moving…….
a satellite in geosynchronous orbit can be stationary, but again the earth is moving……
you could never be absolutely stationary because everything is moving at different rates so you will always be moving in relation to something on an infinite scale of relativity.
