Answer 1

Which evidence supports the big bang theory? Check all that apply.

-Many galaxies exist.
True

-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.

Answer 2

Most galaxies are moving away from us

or Galaxies spin faster than they should based on visible matter.

Step-by-step explanation:

After big bang all the galaxies are moving away from us due to the impact

and due to the impact the rotating speed of galaxies have increased.
