Discussion Overview

The discussion revolves around the theoretical possibility of creating a universe in a laboratory setting using concepts from m-theory and the mechanics of black holes and repulsive forces. Participants explore the feasibility of such an endeavor, the necessary conditions, and the implications of existing theories.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant references a BBC special suggesting that a universe could be created in a lab, potentially starting with a miniature black hole that develops a repulsive force to expand.
  • Another participant questions the feasibility of a black hole detaching from our universe, noting that material things do not disappear from observable reality and referencing Leonard Susskind's work on the topic.
  • Concerns are raised about the nature of black holes, including their properties and the lack of mechanisms that would allow them to detach from our universe.
  • A participant cites Andrei Linde's inflationary cosmology model, proposing that a small amount of matter in a vacuum-like state could lead to the self-reproduction of multiple universes.
  • Discussion includes references to wormholes as a potential but unlikely means of achieving separation from our universe.

Areas of Agreement / Disagreement

Participants express a range of views, with some supporting the theoretical possibility of universe creation and others raising significant doubts about the mechanisms involved. No consensus is reached regarding the feasibility or specifics of the proposed ideas.

Contextual Notes

Participants highlight limitations in current understanding, including the nature of black holes, the implications of unobservable phenomena, and the speculative nature of the ideas discussed. There are unresolved questions regarding the mechanics of universe creation and the role of repulsive forces.

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?
 
Physics news on Phys.org
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 laboratory:cool:http://utilitarian-essays.com/lab-universes.html
