Evidence of events that happened before the Big Bang can be seen in the glow of microwave radiation that fills the Universe, scientists have asserted.
Renowned cosmologist Roger Penrose said that analysis of this cosmic microwave background showed echoes of previous Big Bang-like events.



The events appear as "rings" around galaxy clusters in which the variation in the background is unusually low.
The unpublished research has been posted on the Arxiv website.


The ideas within it support a theory developed by Professor Penrose - knighted in 1994 for his services to science - that upends the widely-held "inflationary theory".

He's got a lot of inertia to overcome if he wants to advance his theory. It's gotten to the point where even layman know that there was literally nothing before the big bang; that this event was where space and time started. At least that what the people who pretend to know have been beating into our heads for some time now...

I think there's definitely something weird going on, here, that somebody is going to have to try explain away if they want to challenge the evidence.

My thought here is if you think you have 'the Beginning' figured out and then it really isn't THE Beginning.....then perhaps the whole theory has to be recalculated. Trying to patch up a flawed theory by assuming it is repetitive may or may not be prove to be accurate. Then again, it could unravel the whole mystery.

Yeah, I think we've often wondered if there were multiple bangs, at least I have. To me it's been an open question.

I'm having a little trouble making sense of the greenish circles in the posted image. How does the image look without the circles? With no disrespect meant for Penrose's expertise, the thing is that he's been pounding the podium on the multiple Bangs idea for some time now. It doesn't seem to be a recently proposed - just a new twist. Assuming such a pattern is there, could these 'circles' simply be an artifact of gravitational lensing? There's no question that there are some curious patterns to be found in the universe. But how does this image represent events (or Bangs) that happened before the Big Bang? I'm still looking at his views, so maybe it'll make more sense. But for now, I'm not really sure what he's talking about.

Apparently I'm not the only one scratching my head about Penrose.

There is no evidence of pre big bang existence. But that does not mean it doesn't exist. We can't see it because of the cosmic microwave backroud.
