Gravitational force is the force which holds each galaxy together . While the rotation of hevenly bodys help then from collapsing down .
BUT fact is this that the universe is expanding the closer these galaxy's are more they keep going away from each other fron this is said that universe is expanding

Gravity holds a galaxy together.
An island comprising billions of stars and nebulae, held together by gravity.
Gravity on both a galactic and intergalactic scale.
Gravity plays a crucial role in galaxy formation and evolution. It acts as the force that pulls gas and dust together to form stars and holds together the structures of galaxies. Gravity also influences the motion of stars and other celestial bodies within a galaxy, shaping its overall structure and dynamics.
Gravity is the most powerful binding force in nature. It holds together everything it can with varying forces.
It holds each shoelace together.
It's what holds them together. (what's it like in your universe? ... since you're implying that yours is different.)
Gravity - from the stars, dust, etc., but especially from "dark matter", a substance of yet unknown composition.
Yes, gravity exists in outer space. Gravity holds the moon in its orbit around the earth. It holds the earth in orbit around the sun. It holds the milky way galaxy together. It holds the local group of galaxies together. And the local group of galaxies might be a group of a string of galaxies held together by the great attractor.
A galaxy consists of stars, gas, dust, and dark matter. Stars provide light and energy, while gas and dust form new stars and planetary systems. Dark matter holds the galaxy together with its gravitational pull. Together, these components create the structure and function of a galaxy, shaping its appearance and influencing its evolution.
There is no reason why it should explode. The gravity that holds it together is way too strong.
A galaxy is smaller than the universe. A galaxy is a collection of stars, planets, and other objects held together by gravity, while the universe encompasses all of space, time, and matter. There are billions of galaxies within the vast expanse of the universe.
