Question

Which of the following correctly explains a difference between the Steady State and Big Bang theories?

The Steady State theory says the galaxies are moving; the Big Bang theory says the galaxies are not moving.

The Steady State theory says the universe is getting smaller; the Big Bang theory says the universe is getting bigger.

The Steady State theory is supported by more evidence; the Big Bang theory is supported by less evidence.

The Steady State theory says the universe was always there; the Big Bang theory says the universe

Answer 1

Steady state theory: universe is always expanding but maintaining constant average density so basically the ratio will always be 1:1 as as the universe gets bigger more galaxy’s are introduced

Big Bang theory: as the universe gets bigger we have the same galaxy’s and no more get created so in short the matter dilutes as the universe expands

Answer 2

The Steady State theory says the universe is getting smaller; the Big Bang theory says the universe is getting bigger.
