Radiation ripples suggest many Big Bangs

Scientists have found new evidence suggesting that the Big Bang might not have been the first or last.
Radiation ripples have been discovered that are thought to actually predate the Big Bang adding support to the idea that we are in but one of several iterations of the universe brought about through a series of Big Bangs.
"What would normally be regarded as a probable entire history of our universe, starting with its Big Bang. . . is taken to be but one aeon in a (perhaps unending) succession of such aeons (sic)," the scientists say.

Amazing.. if true i wonder what I am in the previous universe...maybe im a computer with pentium 1 processor trying to run windows 7 with my 16 MB ram hehe...like im trying to understand this thread but failed.. Why do we need to come up with God in everything anyways?.. so it be easy for us to understand?... Im gonna call frequency as God starting today.. everything is about frequency..Without freq.. there exist nothing.. Frequency is a conception, it's not a physical object.

Just when you thought you had all the answers... So does this mean that when someone starts off on a long story about THE BIG BANG, I can ask "which one?" I guess this also means the universe could be even older than estimated Could even have been going forever, it's a shame our puny brains can't comprehend the concept of infinity, it would be nice to be able to grasp what we're dealing with here better . I guess it'll be interesting to see if they can give us the number of previous universes there has been with these radiation 'ripples', that would put a great perspective on how insignificant...

I guess it'll be interesting to see if they can give us the number of previous universes there has been with these radiation 'ripples', that would put a great perspective on how insignificant we are in time and space. They (as in Sir Roger Penrose and Co.) can't. All they can say is that the apparent (I personally don't believe it is real) radial asymmetry in the CMB is evidence of pre-existing asymmetry in the big bang - which would have originated in the prior big crunch cycle. This idea also puts some firm limits on the ``strength'' of dark energy (should such a thing actually exist) which ... [More]

I don't get it... I don't doubt the science but I am curious - how do we date something to before the big bang? some of the old stars may be older than our universe.

What I fail to see, is how can they see radiation ripples if supposedly between each cycle of the universe everything is imploded back down into a singularity? Would the radiation ripples not be compressed into this as well, thus destroying any evidence of them? Good question! =)

Who ever said god was involved? That makes no sense at all. Adding some type of god to the scenario just complicates things even more. Sorry but, I'm right.

WHAT happened before the beginning of time is—by definition, it might be thought—metaphysics. http://www.economist.com/node/17626874

I love it. Proves my theory correct. It's amazing how some are saying that the universe had to have a causation in order to exist, if that's the case, then what created the causation? The universe is all of space and time so it's against the laws of physics that anything is outside of it.

So I guess it's turtles all the way down, and there's nothing but turtles who have always existed and always will exist.

Lots of new stuff goes against and/or defies our what we think we know. A lot of stuff just gets left behind, we figure we understand something, and when we look closer with a fresh set of eyes we think "what the f..." =) Here's the latest most interesting (in my opin...
