      •A black hole is a place in space where gravity pulls so much even light can not get out. The gravity is so strong because matter has been squished  o a tiny space.

      • According to "relativity" a black hole creates a singularity, but what is a singularity?

                              Singularity

     •In the center of a black hole is a gravitational singularity, a one dimensional point which contains a huge mass in an infinity small place, where density and gravity becomes infinite and space-time curves infinitly and where the laws of physics, as we now them, cease to exist.

      •Singularities were predicted as a result of Einstein's theory of general relativity which resulted in theoretical existence of black holes. In essence, they predicted that any star reaching beyond a certain point in it's mass, a.k.a. the Schwarzschild Radious, would exert  a gravitational force so intense it will collapse therefore creating a black hole

                        Event Horizon

      •The event horizon is a threshold around the black hole where the escape velocity surpasses the speed of light. Sadly according to the "special relativity" nothing is faster than the speed of light if it would make its mass infinite as well as the required force to move it.

       •Rotation can also make a black hole more effective at converting matter to energy. A nonrotating black hole (singularity) would convert about %5.7 of an falling object's mass to energy, following Einstein most famous equation E=mc². In contrast, a rotating black hole (ringularity) could convert upto %42 of an objects mass into energy, scientist have determined.

R = Schwarzschild radious
G = Gravity constant
M = Mass of a black hole
c = speed of light

             Traveling To A Black Hole

        •Well I don't recommend it, but let's talk theoretically about a travel to a black hole.
Distant observers will only see regions outside the event horizon, but individual observers falling into a black hole would experience quite another "reality". If you got into the event horizon your perception of time and space would entirely change. At the time, the immense gravity of black hole would compress you horizontally and stretch you vertically, that's what scientists call (no joke) "spaggettification"

                    Does Black Holes Die
       • Black holes can shrink, they are loosing tiny amounts of energy called "Hawking Radiation ", it occures that the space isn't empty, there are a see of radiations randomly roaming around the space. After they finished their energy they disappear, however their energy consumption is so little that they might die after  happen billion billion billion...  you get the point :)
