Like our galaxy contains billions of stars, the universe contains billions of galaxies.
Yes, galaxies like the Milky Way are part of galaxy clusters that move through the universe, but they do not orbit a single object like planets orbit a star. Instead, galaxies are influenced by the gravitational forces of other galaxies and dark matter in the universe.
The order from largest to smallest is universe, galaxy, star, and planet. The universe encompasses everything, including galaxies like the Milky Way. Within galaxies, there are stars like our sun, and planets like Earth.
Galaxies are vast collections of stars, gas, dust, and dark matter, and they are the fundamental building blocks of the visible Universe. Clusters of galaxies consist of groups of galaxies bound together by gravity, showcasing the large-scale structure of the cosmos. Together, these galaxies and their clusters form a complex web-like arrangement known as the cosmic web, which defines the distribution of visible matter in the Universe. This structure helps astronomers understand the evolution and dynamics of the Universe over time.
There are other galaxies. Between the galaxies, there's lots of mainly empty space, with a very tenuous gas.
The moon around the earth. The earth around the sun. Giant teacups around the teapot on a ride at Disney World.
Sure. Why not!
we won't be able to answer this question for another 200 years!
Galaxies and stars are not evenly scattered due to the influence of gravity, which causes matter to clump together over time. In the early universe, tiny fluctuations in density led to regions of varying gravitational pull, attracting more matter and forming structures like galaxies. Additionally, the expansion of the universe and interactions between galaxies, such as mergers and collisions, further contribute to the uneven distribution of cosmic structures. This results in the large-scale web-like structure of the universe, where galaxies are found in clusters and filaments, separated by vast voids.
The Big Crunch: Like the opposite of the big bang, the universe collapses and goes into a point of singularity. The Big Chill: The universe will keep on expanding, until there is too few galaxies and stars, which will eventually die out too, so there will be nothing in the universe but a few black holes and decayed stars and galaxies
No. The Milky Way galaxy is just one of billions of galaxies in the Universe. Just like there are billions of planets in the Milky Way Galaxy, there are also comparable numbers of planets in other galaxies.
