Black holes are among the most
fascinating and mysterious objects in our universe,
but what exactly is a black
hole and why are we so fascinated by them.
Einstein told us that gravity is a result of mass and energy
curving space-time, and black holes are regions
of the space-time where gravity is so
strong or space-time is so curved that
not even light can escape and this sends
black holes and credibly simple objects
arguably the most simple in nature they
are merely extremely curved regions of
space-time and yet in spite of their
apparent simplicity they may be the door
to unlocking some of the most difficult
to open questions in theoretical physics
today the key that unlocked this door
was provided by Stephen Hawking who
showed in the 70s that black holes are
not so black when quantum effects are
taken into account but rather they leak
a low energy quantum radiation the
consequences of this discovery remain
one of the most exciting and
far-reaching areas of theoretical
research today DC U is now enrolling for
its new masters in astrophysics and
relativity for details see DC ue4 slash
