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
* Gravity has infinite range and thus an object will always have some force acting upon it, which will move it even if imperceptably
* Unless an object is at absolute zero, which is impossible, heat will make its molecules shift and wiggle, even if very slightly
* “Stationary” isn’t even a really well-defined term here
