Assuming galaxies spin around their black holes, wouldnt a planet closer to the center move alot faster and therefore experience time alot faster?

A planet near the black hole would experience time much slower, not faster. Being in a gravity well slows down time relative to a point far away from it.

Yes but again it’s really only noticeable towards to unimaginable extremes with things like that we are talking only a few seconds maybe different for an entire year max. You probably can’t get to or will not survive anything that’s in the extremes

Sorry for the continued questions but would this apply to galaxies further out towards the edge of the expanding universe considering the universe is expanding so fast that galaxies are moving away from us at (cant remember the exact speed) lets say lightspeed? Appreciate your time, just a boggling thought

To the observer us say a galaxy moving away at the speed of light time would stop for them as we view it because the light would no longer be able to reach us as they are traveling away just as fast as light. They out there on the other hand would kinda see the same thing of us time would stop as they are moving away to fast even though it would appear we are moving away to fast because everything is moving away from everything else all at the same time.

Makes sense, i hope we find more answers soon! Very captivating stuff

Those galaxies moving away from us are not moving through space. They are carried away by expanding space. That's a very important difference. A lot of this stuff applies only to things moving through space.

We are "the edge of the expanding universe" from the perspective of the galaxies you are mentioning. Any given location in our universe looks like it's the center, so the edges of our own observable universe would not be experiencing anything different than ourselves.
