dear friends,

be well, be love.

three cosmic enigmas, one answer 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.
the audacious idea comes from george chapline, a physicist at lawrence
livermore national laboratory in california, and nobel laureate robert laughlin
of stanford university and their colleagues. last week at the 22nd pacific coast
gravity meeting in santa barbara, california, chapline 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. this radical suggestion would
get round some fundamental problems posed by the existence of black holes. 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 spacetime "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.
