New Scientist magazine, in the August 21 issue (not on the net yet) reports that Sean Carroll and Jennifer Chen of U. Chicago have calculated the probability of another Big Bang, at any given point and time. It is 1/10^10^56. I.e., 1 divided by 1 and a hundred million trillion trillion trillion trillion zeros, whatever that number might be called. In other words, unlikely. It is so small, say Carroll and Chen, that units are unimportant: it doesn't really matter whether it's the chance of a Big Bang per cubic meter per day, or one per cubic light year per second. It's small.
Thank heavens. The prospect of Creation going off in my morning coffee cup fills me with dismay.
The concept here seems to be that there is 'vacuum energy' left over from our own Big Bang, that is in a state of constant fluctuation. If, by random chance, the fluctuation in the vacuum energy at one point of space becomes very great, you have a Big Bang, and new universe could be created inside the one we already have.
Note that although the probability is very small, it is finite. Given infinite time, it will happen.
It may be the way our own universe started. In someone else's coffee cup.

|Left radical is 'gold/metal' (金), right radical is a Non-General Use character meaning 'hill', which acts phonetically to express 'strong'. This character originally referred to any strong metal; now it usually means 'steel'. Henshall suggests as a mnemonic: 'Metal in hills proves to be steel.'|
