Who believed that the universe always existed?

Although the most scientists agree that the Universe began with the Big Bang, there were some who disagreed. Three Brithish scientists put forward the Steady State Theory. According to this theory, the Universe looks the same no matter the viewpoint, and the Universe has always looked like this. To put it simply, the Universe is uniform throughout both time and space, and had no 'begining'. The Steady State theory is simple, it had no answer to the many phenomena found in the Universe. As a result, it gradually lost its supporters.
