black holes 'do not exist'philip ball these mysterious objects are dark-energy
stars, physicist claims. black holes are staples of science fiction and many
think astronomers have observed them indirectly. but according to a physicist at
the lawrence livermore national laboratory in california, these awesome breaches
in space-time do not and indeed cannot exist.
over the past few years, observations of the motions of galaxies have shown that
some 70% the universe seems to be composed of a strange 'dark energy' that is
driving the universe's accelerating expansion.
george chapline thinks that the collapse of the massive stars, which was long
believed to generate black holes, actually leads to the formation of stars that
contain dark energy. "it's a near certainty that black holes don't exist," he
claims.
black holes are one of the most celebrated predictions of einstein's general
theory of relativity, which explains gravity as the warping of space-time caused
by massive objects. the theory suggests that a sufficiently massive star, when
it dies, will collapse under its own gravity to a single point.
but einstein didn't believe in black holes, chapline argues. "unfortunately", he
adds, "he couldn't articulate why." at the root of the problem is the other
revolutionary theory of twentieth-century physics, which einstein also helped to
formulate: quantum mechanics.
