Like our galaxy contains billions of stars, the universe contains billions of galaxies.
A universe is a very big realm of darkness with galaxies in it. and there are billions of galaxies in the universe! One of those galaxies is our solar system, and in that solar system is our planet. There probably is even more then just one univserse. O_o Well... Galaxies are within the universe and a universe is defintly bigger then a galaxy
There's nothing between the galaxies. It's just other galaxies that float around the universe.
As the universe expands, the density of galaxies decreases. This is because the space between galaxies increases as the universe expands, leading to a lower concentration of galaxies in a given volume of space.

The collection of all galaxies and the space between them is known as the universe. The universe is vast and contains everything that exists, including stars, planets, and dark matter.
Assuming the questioner meant "how many", the present estimate is: between 100 billion and 200 billion galaxies, in the observable Universe.
Peculiar velocities are the individual speeds at which galaxies move within the universe, separate from the overall expansion of the universe. They differ from the general motion of galaxies because they are influenced by local gravitational interactions between galaxies.
The generally-accepted explanation for the redshift is that galaxies move away from us; this means the Universe is expanding.
The distance between galaxies is significant in understanding the vastness of the universe because it shows the immense scale of the cosmos. The vast distances between galaxies highlight the sheer size and expanse of the universe, giving us a sense of how small and interconnected we are in the grand scheme of things.
The Universe Is the whole, where all the galaxies are, and galaxies are just big clusters of starts, planets and different types of debris.
The universe comprises all matter in space. This includes a very large number (200 billion to 2 trillion) galaxies. Each galaxy comprises a very large number of stars: our contains 100 thousand million stars.
