How the Universe Began

Heather Couper presents a narrative history of astronomy.

The discovery that the universe is expanding led cosmologists to suggest that its origin lay in a compact, dense, hot fireball. Cambridge astronomer Fred Hoyle thought this so ridiculous that he disparagingly called it the big bang. The name stuck and there followed intense arguments between supporters of the big bang theory and Fred Hoyle and his colleagues, who favoured a steady state universe.

A decisive blow to the latter theory came from a radio telescope in New Jersey in the early 1960s that detected a gentle background glow at microwave radio frequencies that theorists had predicted as the dying embers of the big bang itself.
