Can we create a universe in a lab using m-theory and repulsive forces?

[Brad12d3]

I just saw a BBC special on m-theory and in the last minute of the show one of the physicist mentions that it could be possible to create a universe in a lab that could detach itself from ours as it expanded. He didn't elaborate beyond that and I wonder what kind of mechanics would be used to pull off a feat like that?

Would it have to happen in a particle collider like the LHC, or is there another way it could be possible? It has been mentioned that it would start with the creation of a miniature black hole but then somehow it needs to develop a repulsive force so that it expands hence creating a universe. Much of my reading into mini black holes suggest they would fizzle away rather quickly due to Hawking radiation. So how would you cause the black hole to have a repulsive force instead of simply fizzing away?

Do you remember who made that remark?..Maybe contact him directly and get a brief explanation...or,,,he may have a website that will explain this.

Some obstacles with that scenario...I'm not saying it's impossible, just beyond anything I have read.

What would cause a black hole to "detach itself" that doesn't exist everywhere else...I have not noticed material things disappearing from this universe...of course most of our universe is not observable, never has been, and never will be...(that will cause some consternation here I am sure).

Leonard Susskind says, THE BLACK HOLE WAR, page 187

If baby universes carry off information (to create a new baby universe) that becomes unobservable...

we can't do any experimental physics..

Susskind also mentions a speculation on your theme: maybe a piece of space inside a black hole breaks off and begins the formation of a new universe...not Susskind's idea...


black holes have 'no hair' except, mass, charge, and spin...they do grow

There is nothing that intrinsically 'detaches' black holes from our universe, any more than acceleration separates it's distant Unruh horizon from our universe or the cosmic horizon is actually 'detached' from our universe...just unobservable...

wormholes are I think considered very,very unlikely, but not althogther impossible...that's a potential route to 'elsewhere'.

Also, I have read from Susskind that string theory contains black holes but I don't know just what that means...you might also follow that avenue...

well according to andrei linde founder of inflationary cosmology model "one may need to have only a milligram of matter in a vacuum-like exponentially expanding state, and then the process of self-reproduction will create from this matter not one universe but infinitely many".I suggest you to read The self reproducing inflationary universe by Andrei linde scientific american november 1994 issue.till the here is an interesting link on it that i found when searching for creating universe in laboratoryhttp://utilitarian-essays.com/lab-universes.html
