It is a little more complicated than that. Beyond the galaxies there is also dark matter; of which science does not yet know its identity, but many observations show it exists. There is also dark energy and we have even less of an idea what that might be (although it might be vacuum energy as explained by some quantum field theories).
Also, this is just the visible Universe. The actual Universe might be much much larger!
The amount of empty space in the Universe, between galaxies, is many times larger than the amount of space occupied by galaxies. This ratio depends on what part of the Universe you are looking at. For example, our galaxy has a diameter of about 100,000 light-years; the closest larger galaxy (M31) is at a distance of about 2.5 million light-years. However, that's just the Local Group; from the Local Group to another galaxy cluster, there is even more empty space.
The question is essentially nonsense. The universe is the universe. It contains galaxies. There's no underlying "structure" to how the galaxies fit together, so it's more or less meaningless to talk about "how they make up the universe."
The galaxy, the one we are in, we call the Milky Way. It is one of billions of galaxies. These galaxies and everything else make up the universe. Compared to the universe galaxies are small fry.
No. Such a task would be impossible.
All matter and energy in space, including stars, planets, galaxies, and dark matter, make up what is known as the universe. This vast expanse of space contains everything that exists and interacts according to the laws of physics.
No. Because it will be impossible for astronomers to make an atlas of at least 100 billion galaxies in the observable universe.
Stars and planets make up a very small fraction of the universe's total volume. The vast majority of space in the universe is empty, consisting of hydrogen and helium gas, dark matter, and dark energy. Stars and planets are concentrated in galaxies, which themselves make up a small portion of the universe.
The universe consists of all space and the matter that space contains, including galaxies, stars, planets, and other celestial bodies. It also includes dark matter and dark energy, which are thought to make up a significant portion of the universe.
Objects in space include planets, stars, moons, asteroids, comets, galaxies, and black holes. These objects make up our universe and can vary greatly in size, shape, and composition.
No, because it will be impossible for astronomers to make a 3D panoramic view of all 100 billion galaxies in the observable universe.
Question does not make any sense.
I don't think anybody has enough information about 100 billion galaxies to do that. The current estimate, that the observable Universe has about 170 billion galaxies, is simply based on observing a small sample of the sky.
