Parallel Universes?

Hi there

This post is going to be on Paralle universes and, the likely or unlikely possibility of there exsistence.

Of course as you know paralle universes are the favourate of sci fi authors and, certain branches of nutty science. You know the like of which who have claimed to have been abducted and then probed by ET. Rather coincidentally next to the pub! Because of this parallel universes are regarded as total rubbish. And about as credible as Atlantis or roswell, but is this absolutely true.

Now don't get me wrong I'm not one of those nutty so called scientists who will quite happily believe anything. I am however inceredibly open to new scientific ideas.

And in recent years there as been new cosmological ideas, ( I won't use theory) that have hinted at the posibility of parallel univereses.

The first of these is Membrane or M theory (sorry if I apear inconsistent but thats it's name). M theory is an addition to the possible theory of everything string theory, string theory is very complicated and therefore very dull if your not interested. So I will give a very simple exsplanation, S theory says that all particles (Protons Electrons) are not points or balls as you would imagine. But very very thin strings that vibrate at diferent resonances, and these different resonances give us the myriad of particles we see. Very briefly there is one crucial problem with S theory as shown in the cartoon above. Mathematically S theory works fine, the problem is as yet there is NO evidence to prove it's true and, NO link between it and the other famous theories Special and General relativity . But of course with the new LHC who knows what will be found.

I am getting into a physics based ramble and you should be spared from that so back to parallel universes. Now in M theory like S theory there are multiple dimensions ranging from six to in some cases eleven, oddly only four of these dimensions affect us. I know sounds odd don't attempt to think about it it only makes your head hurt! Now these six to eleven dimensions make up a higher space sometimes known as the multiverse which contains branes. The concept of the multiverse does have a small shred of evidence to it's name. As you know out of the four forces gravity is the weakest and, this is believed to be due to the fact that gravity is the only force that provades the multiverse.These branes are formed from quantum fluctuations (something out of nothing ) in the vacuum. And are like cosmic paving slabs that through Gravity come together strike and form big bangs, then seperate and collide again with other branes. And thus a myriad of parallel universes are created evolve and die!

Again like string theory there is very little evidence for this idea, although the same was true of the big bang at the start of the 20th Century so who knows what will happen. It is also rather satisfying to people who wonder what started the big bang. It also makes the concept of parallel universes a bit more plausible, although I don't claim for a moment it is certain proof of anything. One thing is certain it is an area that needs more serious research. For anyone reading this who wants to know more I recommend Endless universe Beyond the Big Bang (search it on Amazon).

Thanks for reading!
