WHAT HAPPENS WHEN SPACE IS WARPED SO MUCH THAT NOT EVEN LIGHT CAN ESCAPE?
BLACK HOLES HAVE MASS, ANGULAR MOMENTUM AND ELECTRICAL CHARGE
-MASS: AT A DISTANCE A BLACK HOLE EXERTS THE SAME GRAVITATIONAL FORCE SUCH AS ANY OTHER OBJECT
-Black holes SPIN RAPIDLY AS THEY FORM.Their fast rotation distorts space and time near the boundary of the blackhole.

-THE SIZE OF A BLACK HOLE DEPENDS ON MASS
- SIZE OF A BLACK HOLE IS GIVEN BY A SIMPLE FORMULA
ANY OBJECT WITH A MASS CAN BECOME A BLACK HOLE IF IT CAN BE CRUSHED TO A SMALL ENOUGH RADIUS
Falling into a Black Hole
TIDES: you can feel the gravity is stronger on your feet than on your head.
It feels like you are being stretched!
As you cross the event horizon, a distant observer sees you TURN redder.
time slows down (your clocks runslower and slower…) finally…you ARE A frozen image as
you cross the event horizon
What to YOU see ?
…the black void is suddenly replaced by an unimaginable array of views.
You see outwards – light falls into the black hole butdoesn’t get out
You are lost to our universe forever.And within a few seconds, you are swept into the massive singularity at the center of the black hole and crushed into oblivion!
