A Short Conversation

[10:16 PM] Awesome McSuper-guy: http://www.ted.com/index.php/talks/view/id/251
[10:16 PM] Awesome McSuper-guy: check that out
[10:17 PM] Awesome McSuper-guy: it's a talk by Brian Greene about string theory
[10:17 PM] Awesome McSuper-guy: this guy's an excellent speaker
[10:17 PM] Steve J: fantastic four is such a terrible movie....if not for jessica alba being hot...I would not continue to watch it...in fact it made be too hard to watch
[10:17 PM] Steve J: im gonna check this out
[10:17 PM] Awesome McSuper-guy: hahaha
[10:17 PM] Awesome McSuper-guy: very true
[10:18 PM] Awesome McSuper-guy: i kept hoping the second one would be good
[10:18 PM] Awesome McSuper-guy: but then i talked to someone who saw it
[10:18 PM] Awesome McSuper-guy: boy were my hopes dashed
[10:18 PM] Steve J: suposedly the LHC may or may prove the string theory wrong
[10:18 PM] Awesome McSuper-guy: yea
[10:19 PM] Steve J: I feel like a lot of theories are riding on this one thing
[10:19 PM] Awesome McSuper-guy: well, if it makes little black holes it'll provide strong evidence for one version of string theory
[10:19 PM] Awesome McSuper-guy: if it doesn't make little black holes it'll disprove several versions of string theory
[10:31 PM] Awesome McSuper-guy: Greene talks a little about the LHC at the end of that video
[10:32 PM] Steve J: but does it have to actually be able to make little black holes (that will destroy the earth) in order to prove it through?
[10:33 PM] Awesome McSuper-guy: little black holes will almost certainly not destroy the earth
[10:33 PM] Awesome McSuper-guy: the same theory that predicts their existence predicts their almost immediate evaporation into a bunch of other particles
[10:33 PM] Awesome McSuper-guy: because of hawking radiation
[10:35 PM] Steve J: yeah I wrote about that in my post...with the crazy lawsuit
[10:35 PM] Awesome McSuper-guy: yeah...
[10:35 PM] Awesome McSuper-guy: Greene says there are other ways tho
[10:35 PM] Awesome McSuper-guy: like if the measured energy of particles created by LHC collisions is less than expected
[10:35 PM] Awesome McSuper-guy: it could be due to some particles escaping through those other dimensions that string theory requires
[10:36 PM] Steve J: hmm
[10:36 PM] Steve J: interesting
[10:36 PM] Awesome McSuper-guy: but a little black hole would be a clincher for string theory i believe
[10:36 PM] Awesome McSuper-guy: because the standard model requires energies much higher than LHC energies to make a black hole
[10:36 PM] Awesome McSuper-guy: but if there really are extra dimensions, the force of gravity will be amplified on those tiny scales allowing for tiny black holes to be created at LHC energies
[10:37 PM] Awesome McSuper-guy: I kinda want to post this conversation on the blog...
[10:37 PM] Awesome McSuper-guy: lol
[10:38 PM] Steve J: u should
