Lee Smolin's Evolving Multiverse

[Maxwell511]

Admittedly I have not read his book and my understanding of the theory is based on a referral in Brain Greene's Elegant Universe.

For those that don't know, Lee's proposal is basically this:

Blackholes are the seeds of new universes which are hidden from us beyond the event horizon. Each universe that is created in a blackhole has slightly different variations in fundamental constants, sort of like a cosmic mutation. So a multiverse exists were universes that are more probe to blackhole formation are more common, this being a solution to the anthropic principle. The reason why the fundamental constants are the way they are is because they are the ones that are probe to form blackholes.

Does anyone know the theoretical support for this idea? Or what is your opinion of the idea?

Personally I believe it to be quite elegant, although the truth of a theory is not based on aesthetics, so it would be nice to know what the foundations of the theory are.

I wouldn't wualify that as a theory, more like a supposition. There's nothing to show that black holes create universes, or that our particular set of universal constants is more or less prone to create black holes then any other. Actually, since black holes are a result of our universal constants (gravity + c) I'm not sure the idea makes any sense period.

I really like the idea but really it's just an idea...Philosophy.

My idea is that black holes are acting as sink to drain away the energy of our universe back to where it came from. As matter 'enters' a black hole it undergoes the reverse process of a big bang where primitive energy was condensed into matter again get broken down into singular dimensional strings to await being born into a new universe.

Well, there is no doubt that there's a lot of stuff going on that we humans don't know about and may never know about. But, like Einstein, I assume that some sort of determinism eventually rules, so "No worries, Mate."

The one thing that to me seems reasonable to assume is that ultimate reality is not anthropomorphic in an sense whatsoever. IOW, I think a extreme amount of humbleness is in order at all times.

This nonsense reminds me of the image of stoners pondering the idea that every atom in their body is a little solar system...and of how many of those solar systems might have planets with intelligent life...

heh heh heh

...and how the government can listen in on any conversation near a phone with a land line...

...and who ate all the chips!

The problem for me is that these "stoners" are both highly respected theoretical physicists. Lee Smolin and Brian Greene are apparently big names in modern day physics. They know their stuff, which suggest to me that they would have some reason to suggest such a theory.

Also, Animal House rocks.

That doesn't sound too absurd to me. The part of the government listening does sound absurd, but it doesn't sound absurd from a theoretical perspective, if the amps are in the right place.

Does sound in a room cause a strong enough electrical signal in a phone wire to be able to pick it up a few metres away? I'd need a look at the circuit diagram of the phone, but I'd doubt modern phones would be capable of doing it, old ones maybe. It would be a great one for Mythbusters.

I know the Stasi developed devices to spy on conservations through the pipes of buildings.
