Was the big bang a quantum fluctuation?
« on: 29/04/2012 11:20:01 »
Sal Napoli  asked the Naked Scientists:
   Dear Chris

We are told that, at a quantum level, the vacuum is a seething caldron with particles popping into and out of existence, more or less cheating the principle of conservation of mass/energy, provided it is paid back quickly enough.  And that the more energetic or massive the particle, the shorter lived it is.

Assuming that the big bang may be represented as the mother of all quantum fluctuations, when will it be paid back?

What do you think?

I don't know. I find 'space' to be comparatively calm myself?
Wish I knew that one actually :)

The Big Bang was a 'singularity', in this case also meaning there is no evidence left that we can probe, as far that I know? There is a 'radiation curtain/fog' if I remember right, hiding those first moments from us as we look out in the universe, backwards in time sort of. But by assuming that the BB becomes a 'energy debt,' we also need to assume that what we have is a relation to something else.

What would that be?

It's easier to assume the universe today to represent a stage in a ongoing BB. Meaning that what we have is a description of phase transitions, relative a/our 'arrow of time'. According to our arrow, and current understanding of the physics we have, it will stay this way for a very long time

If as yor_on expressed
"the universe today to represent a stage in a ongoing BB. Meaning that what we have is a description of phase transitions, relative a/our 'arrow of time'. "

Time reverses every half cycle, so after one complete cycle the debt has been repaid.

I've seen some arguing that dark energy is some sort of 'seething' vacuum energy though, accelerating a expansion? There are a lot of weird stuff associated with that sort of thinking, at least to me. It depends on how you then would define the conservation laws as we get new 'space' that then also can be defined as 'seething', and where it would 'come from' etc. It all depends on how you define your universe :) it seems.
