How are the steady state theory and big bang theory the same?

The similarities in the big bang and steady-state theories are few. But their similarities are listed below:)

Explanation:

Both theories explained the galaxies discovered by Vesto Slipher, Edwin Hubble  and Milton Humason. They each don’t have an answer for everything. Such as the big bang does not explain the ball of matter and the steady-state does not explain how the universe was formed.

Hope this helps:)
