What is the difference between the Big Bang theory and the Steady State theory?

1 Answer

In 1929 astronomers found that the galaxies are going away from each other by the study of red shift.

Explanation:

This made astronomers to think about the expanding universe,.Soa theory was formed known as big bang. This says about 13.82 billion years back universe was a very small object started form from a big explosion and it began to expand./.Later the remnants of that explosion was found i the cosmic micro ground radiation every where ..So expanding universe is the proof for Big Bang along with CMB Radiation.
Steady state theory says the universe is as it is and remain same..New matter is created in between galaxies. This theory is getting out as more and more proof are coming in favor of Big bang.
