When Stephen Hawking contradicts his own theory, that's a
paradox worth noting.  'It’s saying there’s no ‘black’ in black
hole'- Amanda Peet, University of Toronto physicist  Like the
black holes he described 40 years ago, the British cosmologist’s
reassessment last week of the concept of "event horizons" is
pulling in chatter from astrophysicists around the world.  What
is an event horizon?  An event horizon is the invisible surface
at which point nothing can escape being drawn into a black hole.
Hawking previously stated that nothing could escape this black
hole, but he has since revised that theory.  It turns out that

the space-time continuum that can devour galaxies and even trap
light forever — may not exist in the way that he proposed
decades ago.  In a new online paper titled Information
