Question #06212

Answer 1

See below

Explanation:

The Big bang is a theoretical phenomenon scientist predicted how every star, and galaxy were made. so there is a possible way to explain the origin of galaxies. but it cant be explained.

Answer 2

Cosmologists have mathematically proved the Big bang to the last fraction of a second.

Explanation:

Here is a graphics which explain the sequence of formation of galaxies from Big Bang. to present stste.

Answer 3

Yes. Big Bang theory provides an explination for how the early Universe could create conditions that eventually formed galaxies.

Explanation:

Big Bang theory describes the evolution of the Universe from its very first moments, through the formation of structure , to the formation of the first stars and galaxies, to its current state of accelerating expansion.

About 13.8 billion years ago, the Universe was extremely hot, dense and almost completely uniform. Most astrophysics think that during this period, when it was about `10^{-36}` seconds old, the Universe went through a period of rapid expansion, called inflation , which blew up quantum fluctuations into huge scales. This created small differences in density, which were the seeds for structures, such as galaxies and clusters of galaxies in the present-day Universe.

Here is a video showing a simulation of the formation of a cluster of galaxies starting from small fluctuations in the density of matter. You will see a series of filaments form. Where the filaments intersect, you get galaxies.

The exact details of how the first galaxies formed and how they evolved to the ones that we see today is still an area of active research in astronomy.
