How do space and gravity work together?

Like space time is the black stuff of space and gravity related in the same way? We know that galaxies are spinning to fast to stay together. They say it is the black stuff that stops or controls them from flying apart. So does gravity and the black stuff work together, and cannot be separated?

  1. Gravity is a very important force. Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It makes it possible to use human-made satellites and to go to and return from the Moon. It makes planets habitable by trapping gasses and liquids in an atmosphere. It can also cause life-destroying asteroids to crash into planets.
