If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

"Big-bang" versus "Big bang"

I spend a good bit of time thinking about what happened in the period of time between the Big-Bang and the Big-Bang. No, I'm not crazy (or at least not with respect to this issue). Rather, the problem is that the term "Big-bang" is often used -- both by professionals in the field and in the popular press -- to discuss two quite different things.

One...

One can use modern terminology WRT big-bang, bigger-bang and BIGGEST-Bnag, information_age ?

I suggest: Giga-Bang, Mega-Bang spawns Mega-verse's ? while big-bang, at least locally can be traced to an initial point, or Monostate, within our Mono-verse, which of corse is the embedding of "singularity" .

Those using the term "before the big bang" are using it to gain attention to their work and that kind of sensationalism would be difficult to stop. The term big bang should continue to refer generically to a past that is increasingly dense and hot, while we convey that the observed history of our universe is not an explosion or a history of existence itself. The past is just another place in time, not so different from the outer cosmic event horizon.

I think Vilenkin is using the term O-region in a way that would be consistent with the clarification you are wanting to make. It wouldn't refer specifically to just that stage prior to the singularity (thinking in reverse), but it respects the orientation of the observer in a way that shouldn't be left out of the description. A "hot bubble" works in the same way but doesn't have a great deal of appeal.

I think simply setting up common language for all stages of the cosmos would be a significant accomplishment and improvement. I have always liked referring to the singularity itself as Alpha, and presently refer to the final state of an accelerating universe (empty space) as Omega.

Anthony, in respect to the period between Alpha and the disintegration of uniformity and symmetry, I recommend approaching Alpha as a charged singularity, in our case the positive half of a neutral whole. Alpha is a symmetry of being perfectly positive, but in a reference beyond itself is the ultimate asymmetry or the most imbalanced state in reality, all positive apart from all negative. The big bang results of the collision between a positive and a negative singularity, which is still happening.

The CMBR has, historically, always been hooked up tightly with the term "Big Bang." Keep "Big Bang" associated with the event(s) understood to have produced the CMBR, and apply some new, completely different name to any putative prior bang(s).

Is there anyone out there willing to think outside the box? What if Joao Magueijo is on to something with a universe capable of C^2? What about William Tiller's ideas of a energy-velocity universe with positve energy and negative energy, C^1 and C^2?

Maxwell could use imaginary solutions in his equations to express the mathmatics of EM. Why stop there?
