Which of Hubble's findings supported the big bang theory? Check all that apply.
grigory [225]

<u>Out of all given options, Hubble's findings supported the big bang theory are as follows: </u>

  • The universe formed from a central point.
  • Most galaxies in the universe are moving away from Earth.
  • There are billions of galaxies in the universe, not just one.

Option C, D, and E

<u>Explanation: </u>

According to big bang theory, the universe is increasing its region of occupancy in free space. As it is known that the universe is composed of several galaxies. So this spreading of the universe is nothing but spreading of galaxies.

And this is confirmed from Hubble’s findings using Hubble’s telescope.  As they have observed that the speed at which the galaxies are travelling in free space has been increased at a faster rate.

So, the galaxies are used to move away from Earth with time at a faster rate which confirms the big bang theory of universe formation. Also, in simple words, universe started from big bang according to cosmology' standard theory, it’s just moves from everything else.
