SCIENTIFIC THEORIES ABOUT THE ORIGIN OF THE UNIVERSE-STEADY STATE UNIVERSE

THE THEORY OF THE STEADY STATE UNIVERSE

The steady state universe was proposed by Sir James Jeans in 1920,  revised by Hermann Bondi and Thomas Gold and developed, to deal with the big bang hypothesis, by Sir Fred Hoyle, where it explained that the universe is always expanding but maintaing a constant average density and  continuous creation of matter. This theory  in other words states that this type universe would be infinite with no beginning or end. However this theory was incorrect thanks all the evidence found since the mid 1960s, such as the observations made by Edwin Hubble about the expantion of the galaxies.
