Gravity plays a crucial role in the formation and structure of galaxies by pulling together gas, dust, and dark matter to create stars and stellar systems. Dark matter, which constitutes a significant portion of the universe's mass, exerts gravitational influence, helping to bind galaxies together and affecting their rotation curves. This unseen matter also shapes the large-scale structure of the universe, influencing the distribution of galaxies and galaxy clusters. Ultimately, the interplay of gravity and dark matter not only determines the morphology of individual galaxies but also their interactions and evolution within the cosmic environment.
What else can I help you with?
Do all galaxies have gravity?
Yes, all galaxies have gravity. Gravity is a fundamental force that exists everywhere in the universe, including within and between galaxies. It is responsible for holding galaxies together, as well as determining their structure and motion.
Do all galaxies follow the law of gravity?
That is what has been observed, except that spiral galaxies rotate faster than would be expected based on the matter we can see. Thus we infer the existence of dark matter in the rims of these galaxies. An alternative hypothesis is that something is terribly wrong with our theory of gravity. To the best of our knowledge the rules of physics are the same no matter where you go.
What holds the galaxies and solar systems together?
Galaxies are held together by gravity. So are Solar Systems. In the case of galaxies, and galaxy clusters, it isn't entirely clear what type of masses provide this gravity - the amount of known matter is simply too small, by a factor of 5-10. For more information, do some reading on "dark matter".
What is the primary force involved in the formation of galaxies after the big bang?
Gravity is the primary force involved in the formation of galaxies after the big bang. Over time, the gravitational attraction between matter caused it to clump together, forming structures like galaxies and clusters of galaxies.
What is a big big idea for sapce and time?
The big idea for space and time is that the universe contains matter. Gravity and energy influence the formation of galaxies, and all matter of the universe.

Does dark matter affect the brightness of galaxies?
By definiton, "dark" matter neither emits or absorbs light. Thus, it does not effect the brightness of galaxies.
What is the relationship between gravity and galaxies?
Gravity plays a crucial role in the formation and structure of galaxies. It is the force that pulls matter together, allowing gas and dust to coalesce into stars and clusters, ultimately forming galaxies. Additionally, gravity governs the motion of stars and other celestial bodies within galaxies, influencing their orbits and interactions. Overall, gravity is fundamental to the dynamics and evolution of galaxies throughout the universe.
Why are our galaxies separated?
For starters, if there were no separation between two (or more) galaxies, it would be considered a single galaxies, not two or more. The reason matter is clumped together into galaxies at all (with separations in between) is because of gravity - gravity tends to do that, i.e., to clump things together.
What holds the galaxies and solar systems together?

Does Gravity affect Matter?
Yes.
What is a force that attracts all matter to other?
Gravity is the force that attracts all matter to other matter. It is responsible for keeping the planets in orbit around the sun and holding galaxies together.
What is gravity and how does it affect matter?
Gravity is a force between any two masses.
What role did gravity play making the sun?
A crucial role. Without gravity, matter would never have gathered together, to form galaxies and stars.
Why do galaxies clump together in clusters and superclusters?
Galaxies clump together in clusters and superclusters due to the force of gravity. Gravity pulls galaxies towards each other, causing them to form groups and larger structures. This clustering is a natural result of the way matter is distributed in the universe.
