We know that the moon formed through a collision between earth and possibly another planet. If so,
wouldn’t the shape of the moon be irregular?
Can spacetime bend and smoothen out celestial objects in space when they’re rotating on their axis or revolving around another object?
In: Physics
The moon is large enough that its own gravity pulls it into a sphere. This is how all large objects behave, it is only those smaller which can maintain an irregular shape overall.
Materials such as stone only have so much structural strength. Under great pressure they will bend and flex.
