Which evidence supports the big bang theory? check all that apply many galaxies exist. planetesimals form in debris disks. most galaxies are moving away from us. uniform background radiation is detected in every direction. galaxies spin faster than they should based on visible matter.

Big bang theory is a cosmic event that led to the birth of the present state of universe. The big bang started with an extremely powerful explosion stemming from a point of singularity to its inflation in the 13.8 billion years of time to form the present observable universe. The aftermath of the big bang is a residual background radiation in the form of microwaves spread uniformly throughout the observable universe. The big bang also gave the momentum to the galactic bodies to move in the empty space and appear as either blue or red shifted in the visible spectrum when viewed through large aperture telescopes like the Hubble telescope.

The following observations support the big bang theory:

1.Uniform background radiation is detected in every direction.

2.Most galaxies are moving away from us.

Most galaxies are moving away from us.  

Uniform background radiation is detected in every direction.        

Explanation:

The Big Bang theory describes the beginning of the universe. According to this theory, the universe was formed 13.6 billion years ago with a Big Bang. Due to this, the universe which was confined to a single having infinity temperature and density, started expanding and cooling down.

The evidence that supports the theory of the Big Bang are

1. Most galaxies are moving away from us. The universe is continuously expanding and that is why the most of the galaxies appear to move away.

2. Cosmic microwave background radiation was detected in every direction which is considered as the remnant radiation from the early stages of the universe.
