Who showed that other galaxies existed?
The astronomer Edwin Hubble provided evidence in the 1920s that other galaxies existed beyond our own Milky Way. By observing Cepheid variable stars in the Andromeda Galaxy, he demonstrated that it was a separate galaxy located far outside our own. This discovery revolutionized our understanding of the universe's scale and confirmed the existence of other galaxies.
Who showed that other galaxies existed and observed that the universe was expanding?

How does the energy of the cosmic microwave background compare to the energy radiated by all the stars and galaxies that ever existed?
The energy of the cosmic microwave background is about 400,000 times less than the energy of all the stars and galaxies that ever existed. The CMB is the remnant radiation from the early universe, while the energy radiated by stars and galaxies have been accumulating over millions of years.
What are two tools used in the big bang theory?
Two tools used in the Big Bang Theory are the telescope, which is used to observe distant galaxies and study the cosmic microwave background radiation, and the particle accelerator, which is used to recreate high-energy conditions similar to those that existed in the early universe.
How does knowing how a star forms help an astronomer study the origins of the universe?
Quasars are the bright centers of young galaxies. Many quasars we can view today existed billions of years ago, and their light is just now reaching us. They are a snapshot of the past, and tell us about how galaxies formed. From wikipedia: "While there was initially some controversy over the nature of these objects, there is now a scientific consensus that a quasar is a compact halo of matter surrounding the central supermassive black hole of a young galaxy."
Who proved that other galaxies existed?
Galileo

Billions of years ago galaxies existed as what?
Hot clouds of dust and reactive gases
Billions of years ago galaxies existed in?
Galaxies. They are just about the same now as they were then. 14 Billion years ago, astronomers believe that the "Big Bang" created matter from energy, which is how they believe galaxies were formed.
