So planets orbit stars. Stars orbit the galaxy. The galaxy forms super clusters with other galaxies moving through space.
What do galaxies orbit and when they form super clusters, what do they orbit/what determines direction/speed/etc of their movement?
From my understanding Andromeda and the milky way will one day collide in a billion years. So we’re obviously pulling each other together. Whats then pulling us along?
In: Physics
Galaxy super clusters don’t orbit anything. They are the largest gravitationally bound objects in the universe. They are actually being pushed away from each other by the expansion of space.
