At some moment, there were minor fluctuations in the matter density in the Universe. This is related to the theory of inflation.Due to gravitation, the parts that had a little more density to start with gathered more mass from the surrounding areas, thus forming galaxies, galaxy clusters, and superclusters.
No. Space holds everything in space. Galaxies are held in space by space.
Nothing is on space. There are two types of 'space' # Galactical Space- Space in Galaxies # Intergalactical Space- Space in between galaxies
The space in between galaxies is far larger than the galaxies themselves.
galaxies are in every direction in space there in clusters and super clusters
yes, there is ten different galaxies
Do you know how many galaxies are in space?It is never ending just like space.
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.
No. There is not ONE galaxy, but billions of galaxies in space.
Galaxies
Billions.
All of them
Galaxies that travel together through space are called galaxy groups or galaxy clusters. These are systems of galaxies bound together by gravity.
