Not generally, but galaxies do collide sometimes. In fact, the Andromeda Galaxy will probably collide with the Milky Way in about 3 billion years or so. In the collision, stars are often "flung" from one galaxy to the other, or thrown out of the original galaxy entirely. Follow the link below to see what happens when galaxies collide!
The best supporting evidence that the universe is expanding is that galaxies are receding from one another, indicating that the universe is expanding over time. This observation is based on the redshift of galaxies, known as Hubble's Law.
The observation that red shifts of distant galaxies gets greater the further away the galaxies are.
No, Neptune and Uranus will never collide. Their orbits do not come anywhere near one another.
Yes. Our own solar system is part of the Milky Way galaxy. Thousands of other systems with planets have been discovered in our galaxy. The number of planets in our galaxy alone prbably numbers in the billions.

Some verbs that can describe actions related to galaxies include "rotate," "collide," "merge," "form," and "evolve." These verbs capture the dynamic processes and interactions that galaxies undergo in the universe. For instance, galaxies can rotate around their centers, collide with one another, or evolve over billions of years.
Because although the universe is expanding, the galaxies within it are grouped into clusters. These clusters are still under the influence of gravity, so slowly, over many years, they are attracted towards each other and can collide with one another.

Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
The Milky Way galaxy and the Andromeda galaxy are moving towards each other that a rate that will make them "collide" in about three and a quarter billion years. "Collide" is in quotes, because galaxies are mostly empty space, so it's fairly unlikely that any of the individual stars making up the two galaxies will physically touch as a result of the "collision"; instead, the two galaxies will just merge into a larger one.
The force that causes galaxies to move away from one another in the universe is called dark energy.
One way to increase the number of stars in a galaxy is for the two galaxies to collide.

Galaxies generally move away from one another.

Yes !
