"The great theories of 20th century physics -- relativity, quantum theory, and the Standard Model [of subatomic particles] -- represent the highest achievements of physical science. They have beautiful mathematical expressions that result in precise predictions for experiments, which have been confirmed in many cases to great accuracy. And yet I have just argued that nothing along the lines of these theories can serve as a fundamental theory. This is an audacious claim in the light of their success." Another quote from the Lee Smolin book. I like the audacity. In fact, if I understand him at all, Smolin has delivered me from an intellectual cul de sac in which I have been stuck. I've been unable to accept the Big Bang as an absolute cosmic beginning, given the huge something-from-nothing stumbling block. So I have said -- in this blog and elsewhere -- that I believe some patching up of the old Steady State theory will again have its innings. But the advocates of ...
