Detailed explanation-1: -A steady-state universe has no beginning or end in time, and from any point within it the view on the grand scale-i.e., the average density and arrangement of galaxies-is the same.
Detailed explanation-2: -The steady-state theory is a view that the universe is always expanding but maintaining a constant average density, 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-3: -In the 1950s the Cambridge radio astronomer Martin Ryle showed that there were more radio galaxies at great distances than there were nearby, thus showing that the universe had evolved over time, a result that could not be explained in steady-state theory.
