Fred Hoyle

« All quotes from this author
 

In the popular mind, if Hoyle is remembered it is as the prime mover of the discredited Steady State theory of the universe. "Everybody knows" that the rival Big Bang theory won the battle of the cosmologies, but few (not even astronomers) appreciate that the mathematical formalism of the now-favoured version of Big Bang, called inflation, is identical to Hoyle's version of the Steady State model.

[The steady-state theory] was a minority view, but [Hoyle] and a few like-minded theorists were able to keep the plate spinning for years. Another Cambridge luminary, Martin Ryle, finally brought it crashing down. An irascible, hardheaded experimenter, Ryle thought theorists like Hoyle were daffy. In a colloquium on sunspots, Mitton reports, Ryle became so incensed by Hoyle's speculations that he dashed to the blackboard and angrily erased the equations.

The Steady State theory was what Karl Popper would call a good scientific theory: it made definite predictions, which could be tested by observation, and possibly falsified. Unfortunately for the theory, they were falsified.

Well, a big question is how did the universe begin. And we, cannot answer that question. Some people think that the big bang is an explanation of how the universe began, its not. The big bang is a theory of how the universe evolved from a split second after whatever brought it into existence. And the reason why we’ve been unable to look right back at time zero, to figure out how it really began; is that conflict between Einstein’s ideas of gravity and the laws of quantum physics. So, string theory may be able to - it hasn’t yet; we’re working on it today - feverishly. It may be able to answer the question, how did the universe begin. And I don’t know how it’ll affect your everyday life, but to me, if we really had a sense of how the universe really began, I think that would, really, alert us to our place in the cosmos in a deep way.

 
Brian Greene
 

The big bang is obviously one form of beginning, but the big bang in itself is unimaginable. It's one thing to think about God making a flower or infusing the planet with love, but to imagine what might be behind the big bang is so removed from real life that it actually loses importance for me. There's so much else to think about that's here and now. I like the Buddhist concept of beginning-less-ness, that the universe has always been going on.
