Yes but eternal inflation also says that the universe is eternal, and what's more, it is in a steady state overall-- much more like Hoyle's idea. So the Big Bang, plus eternal inflation, is actually very close to steady-state cosmology (not static cosmology, note). Putting in quantum corrections that eliminate eternal inflation thus takes the whole picture very far away from steady-state cosmology, I don't think Hoyle would have liked it, though he would have liked the absence of an origin.magneticnorth said:Hoyle's model was rejected with the discovery of the red shifted light spectrum of objects observed , indicating a velocity away from us . Hoyle basically argued that the redshift was being misinterpreted . Hence Hoyle was arguing that the Universe was perpetual . This is similar in part to what Das is indicating .
I realize you are not arguing in favor of the model, nor I against it, I'm merely pointing out that nothing has really changed because we have no new observations, and no more reason to believe in or reject inflation. Also, the Das model is farther from Hoyle's cosmology.I didn't say I subscribed to it , just noted an irony ,since what they are saying resembles more closely in one respect, to what Hoyle was arguing .
I think Hoyle ended up with a view that was a lot like eternal inflation. His view was always consistent with cosmological redshifts, but not with changing populations in the universe, like quasars. But when it was clear quasars did exist, Hoyle just modified his views to allow some secular evolution, but still an ongoing creation process that preserves a steady state overall. That's pretty much exactly what eternal inflation is, but there would be no need to invoke eternal inflation with the Das approach.I just found it curious that Hoyle , in view of those discoveries , still held to the Steady State model .
