I was watching a show recently where Roger Penrose explained a new idea he had on the Big Bang. It was very interesting, and I thought I was recording it. Of course, it didn't, now I can't remember exactly what he said, and of course, can't find it anywhere else. Perhaps somebody can feel in the details for me?
His idea was basically cenerted around the accelerating Universe and that it would keep on expanding. It also hinged around the idea that photons, or any massless particle really, does not experience the passage of time.
He went on to say that as the Universe expanded, eventually all matter would be trapped by a Black Hole and the Black holes would evaporate way. Eventually, there would be nothing left in the Universe but cold, cold, radiation, or massless particles that cannot sense the passage of time.
With nothing left in the Universe to experience time (i.e. matter), time itself would cease to exist.
Now, assuming I'm not already totally twisting his ideas around, here is where my memory gets fuzzy.
He then went on to say that without time, there would somehow not be space. I missed his logic entirely on this point. But, to continue, this big empty Universe we would picture at this point, somehow is gone. The infinite expanse of space becomes the infintesimal. And, then you have another Big Bang ... somehow.
So, it's a cyclical model, really.
Does anybody know more about this idea/theory of Penrose, and maybe know where I can go to find out more?
Thanks!
