truth is, I don't think anyone has. It's probably just one big government LIE.
Hubble, in his studies of Nebulas which turned out to be galaxies.
Mister Edwin Hubble did just that, before the 1920's, many astronomers thought that our galaxy included everyobject in space, in 1924 Edwin Hubble proved that other galaxies existed beyond the milky way
The person who discovered the existence of galaxies outside of the milky way was Edwin Hubble. He also discovered that galaxies move away from each other with a constant acceleration, leading to the big bang theory.

The Milky Way is our galaxy, the are no other galaxies within it though we are part of a local group of 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.
Spiral galaxies
no we couldn't because galaxies mean the milky way and if the milky way wasn't here we wouldn't
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.
There are billions of galaxies in the Universe.
