I don't have a degree in physics(yet)but I do know alot about it."DARK energy and dark matter, two of the greatest mysteries confronting physicists, may be two sides of the same coin. A new and as yet undiscovered kind of star could explain both phenomena and, in turn, remove black holes from the lexicon of cosmology."Didn't Einstien say that matter was a from of energy and energy has math withe E=mc^2"suggested that the objects that till now have been thought of as black holes could in fact be dead stars that form as a result of an obscure quantum phenomenon. These stars could explain both dark energy and dark matter."That sounds like a black hole to me.But I think it might possible that they could both dark energy and dark matter" One such problem arises from the idea that once matter crosses a black hole's event horizon - the point beyond which not even light can escape - it will be destroyed by the space-time "singularity" at the centre of the black hole. Because information about the matter is lost forever, this conflicts with the laws of quantum mechanics, which state that information can never disappear from the universe."conflicts with laws of quantum mechanics(QM)?It might be but physicst have seen this since Genral revility(GR) and the possiblity of black existence.The problem is that if that black holes have gravity so strong and are small that to do they apply the laws of GR because they have strong gravitonal force or the Laws QM because there so samll.Physicst have been working on this for a while what is know as the "Grand unifed feiled theory" that explains both QM felid foces with Gravity(GR),which is only force hasn't been unifed with the other's.If they can find the Grand unifed feild theory then we would have a better understanding of black holes and pretty much(if not all)of everthing."Though this anti-gravity effect might be expected to blow the star's shell apart, calculations by Francisco Lobo of the University of Lisbon in Portugal have shown that stable dark energy stars can exist for a number of different models of vacuum energy. What's more, these stable stars would have shells that lie near the region where a black hole's event horizon would form"Note: Anti-gravity existnece is still debated.Einstien model of gravity is based on the geomartry of the unviserse it works as slope and your not being pulled by gravity it's simpely just a shortest distance between today and tommorw.Under this model gravity is in a univerese containtiang only postive mater.Anti-gravity requires negtive-mass which I do think exist (at least natuarrly) in the universe.+digg.

Actually, he did just get lazy ;) Well, not lazy, but he had to throw in a fudge factor to make it work:<a class="user" href="http://en.wikipedia.org/wiki/Cosmological_constant">http://en.wikipedia.org/wiki/Cosmological_constant</a>

No basis? You should really not speak out of ignorance. If you don't know, then don't assume to know.

foolish scientists!SG-1 does exist!
