Coachscientists believe that more distant galaxies formed when the universe was younger and gas clouds began to collapse under the force of gravity, leading to the formation of stars and galaxies. This process took place over billions of years, shaping the structure of the universe as we see it today.

What do scientists believe your galaxies was created from?
Scientists believe that galaxies were formed from the gravitational collapse of large clouds of gas and dust in the early universe. As these clouds collapsed, they formed smaller structures that eventually evolved into galaxies. The exact mechanisms of galaxy formation are still an area of active research in astrophysics.
Why do astronomers think that quasars represent an early stage of galactic evolution?
Astronomers believe that quasars represent an early stage of galactic evolution because they are extremely luminous and compact objects located at the centers of galaxies. The high luminosity of quasars is thought to be powered by accretion onto supermassive black holes. This intense accretion phase is believed to occur during the early formation of galaxies.
How long ago did the galazies form?
Galaxies began forming around 13.6 billion years ago, not long after the Big Bang that created the universe. Over time, gravity caused matter to clump together, eventually forming the galaxies we observe today.
The scientist who proved the existence of galaxies other than the Milky Way was who?
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
Which force do scientist hypothesize formed your solar system?
Gravity.
