Roll up, roll up – more Big Bangs for your buck here.

‘We have reason for thinking the Universe we observe goes on much further, almost certainly one thousand times further and maybe so much further that all cosmological options are repeated’ – Lord Rees
There may have been more than one Big Bang, the Astronomer Royal has said and claims the world could be on the brink of a revolution as profound as Copernicus discovering the Earth revolved around the Sun.
Lord Rees said that other universes may exist which are unconstrained from the laws of Newtonian physics, with different atoms and gravity fields. But other universes more like our own could also exist, raising the prospect that humanity, or something like it could have evolved elsewhere.
“Many people suspect that our Big Bang was not the only one, but there’s a whole ensemble of Big Bangs, a whole archipelago of Big Bangs,” he told The Hay Literary Festival in Wales.
“This raises another question. Even though the laws of physics are the same everywhere we can see in our observable region, if physical reality is far more extensive, then maybe there are domains where the laws are different.
“There are some theories which suggests that in the aftermath of other Big Bangs the universe may cool down differently governed by different laws.
“This has some interesting implications. It could be that the different Big Bangs cool down with different gravity, different atoms etc and then what we call the laws of physics will, in this grander perspective, be just parochial bylaws in our cosmic patch, governed maybe by some deeper set of laws, but just environmental accidents.
“Maybe we are due for a further Copernican revolution and say there are many Big Bangs and some are tuned some life and others are not. This is a speculation but it is a very exciting one.”
The report concludes with this:
“There may be a lecture like this where people are listening and we may all have avatars.
“It may be some comfort that way beyond our horizon you have an avatar that makes the right decision whenever you make a wrong one. That’s a possibility.”
Another possibility is that something was slipped into his drink…
