rrw4rusty Posted October 31, 2009 Posted October 31, 2009 (edited) Welcome to the twilight zone... trying to bring science to fiction to science M-Theory Explains Dark Matter M-Theory brings the five different string theories together. The Theory predicts an 11th dimension, Membranes or branes and also a closed-loop zero-mass string which turns out to be a graviton. It says that branes can stretch out to enormous sizes (i.e. to the sizes of universes), that these membranes are places where strings can attach their ends, and that these different branes represent different dimensions. We can only see and interact with matter made from strings attached to, or touching our brane. We cannot detect or interact with other branes (i.e. dimensions). M-Theory offers explanations for at least a couple of unresolved anomalies. One is the apparent weakness of gravity compared to the other forces. Since gravitons are closed-end strings they cannot attach to branes like other strings and so they float from brane to brane and perhaps in-between them. Ergo gravity is shared by all branes thus diluting its strength. Another is Dark Matter: the rotation of galaxies as well as other phenomena indicates that there is a whole lot of matter that is missing. Or, put another way, there is a lot of gravity that seems to have no corresponding matter. Since gravitons float between branes it would make sense that this mysterious gravity could be coming from the gravitons not on our brane. Put another way, gravity is mysteriously weaker than it should be... while at the same time we have a bunch of gravity with no mass to account for it. Three things could be happening: 1. Gravitons passing through our brane could be leaving gravity behind 2. We could be picking up gravity from gravitons not within our brane 3. Both of the above Also, if #1 and gravity were leaving another brane and coming to ours, some of those gravitons might be coming from a location on the other brane that has matter but the corresponding location on our brane (if such a thing is possible) does not and so either between branes or while leaving the other brane and entering our brane the graviton would be pulled towards the matter in out brane. This would cause a pattern of gravity which seems to border the mass in our brane which is about what we see when tracking Dark Matter using gravitational lensing. If #2 then mass among all branes would tend collect in the same areas with the same result. Rusty Edit: We have a lot of missing gravity in the form of gravity being so much weaker then the other forces. We have a lot of extra gravity in the form of Dark Matter. Doesn't it seem likely that these two properties are related? Edited October 31, 2009 by rrw4rusty
DrP Posted October 31, 2009 Posted October 31, 2009 Wow! See, I said this cause problems - my post has been thought away into nothingness already!. Be carefull.. Lest my Brane explodes.
