GENERAL KNOWLEDGE

Detailed explanation-1: -steady-state theory, in cosmology, a view that the universe is always expanding but maintaining a constant average density, with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession.

Detailed explanation-2: -One of the elegant features of the Steady State theory is that because the Universe is infinitely old the question of its origin doesn’t arise. It has always existed.

Detailed explanation-3: -Steady-state theory was a theory proposed in 20th-century cosmology to explain evidence that the universe was expanding but still retain the core idea that the universe always looks the same, and is therefore unchanging in practice and has no beginning and no end.
