All About Black Holes
A Black HoleWhen you look at the
simplistic coat hanger and
paper mache models of the solar system in your science class you might be tempted to believe that scientists have
the universe figured out. Think again. The universe is a
crazy place - full of crazy things that we can't quite explain. Check out the 411 on one of the
strangest phenomena we've found so far - black holes!
What Are Black Holes?
Simply put, a black hole is a region of space from which
nothing can escape. It's created when a star dies. That's right, just like everything else, stars are born, age and die. When a
star is dying, it burns up all the
fuel inside of it, explodes into a
supernova (the giant explosion caused by a star dying) and the remaining matter crunches down into a small point called
singularity. This point's gravitational pull is so strong that it turns into a giant vacuum. Nothing can escape it - not even
light! Since black holes absorb light, you can't see them (they're called black holes for a reason) but you can see the
cluster of planets and stars that have been sucked towards the hole by it's enormous
gravitational pull.
Unlocking the Mysteries of Black Holes
Scientists can't quite figure out what happens to stuff that gets
sucked up by black holes but they sure do have a few theories. You see, one of the
basic laws of physics is that matter and energy can never be
created or destroyed - they just change forms. So peeps get pretty confused when black holes suck stuff up and then eventually
disappear without a trace. For thirty years,
Stephen Hawking, one of the world's most respected physicists, claimed that energy and matter can never escape black holes. This led some other researchers to speculate that black holes are either the only place where matter and energy can be destroyed or that may be
portals to other universes. Now, much to the disapointment of
science fiction fans everywhere, Stephen Hawking has conceded that perhaps information
can escape the grips of a black hole. The smartest people in the world can't figure this stuff out so don't feel bad if some of this is a little confusing.
Black Holes - Did U Know?
It takes trillions of years for a black hole to disappear.
There is a giant black hole in the center of our universe.
Black holes are heavy. The black hole at the center of the Virgo constellation is only a few miles wide but it weighs as much as 3 billion of our suns.
