In general relativity, mass and energy are known to cause the curvature of spacetime, which we perceive as gravity. This curvature creates what we call gravity wells; a spacetime shape. How about we shift our focus from just considering mass as the main cause of gravity and start looking at the shape of spacetime itself as the primary cause of gravity?
The overall shape and curvature of the universe play a huge role in how galaxies and other large cosmic structures behave. Galaxies, with their massive gravitational wells, definitely add to the universe's overall curvature. This interaction between gravity wells and the universe's global curvature is an important part of cosmology.
From inside a galaxy, the universe's curvature might look a lot like the curvature of a gravity well. This shape could have noticeable gravitational effects at the edge of a galaxy, especially if it's really big. Maybe this curvature is what we call dark matter.
Even more interesting is the idea that the entire curvature of our universe could create a shape that causes gravity—or more accurately, anti-gravity—leading to the universe's expansion. This implies that the massive gravity of the whole universe based on shape results in a fine balance of forces governing the universe as a whole.
