In a nutshell, a black hole is that area of space surrounding a singularity in which the escape velocity is greater than the speed of light.

No one knows for sure- It may be a star with such a great density that not even light can travel fast enough to reach escape velocity and break away from the gravitational pull.
Some also think it may be a tear in the fabric of space…it's believed that our own Milky Way galaxy has a black hole in the center of it.
Quantum Physics also uses micro black holes to help explain phenomena observed while creating strange particles. The world on the scale of the Atom is truly mind blowing!
Messenger particles are believed to travel faster then light- there has been some evidence of particles escaping black holes "sprits" I believe they are called.
Messenger particles helped explain the top & bottom spin of a pair of particles that have been separated by a large distance… Reversing the polarity of one particle in the pair resulted in the other particle instantly spinning the opposite way, no matter what the distance- which would indicate something other then the speed of light was moving to keep the two particles in contact with each other… very amazing!

A black hole is a region of space in which the gravitational field is so powerful that nothing can escape after having fallen past the event horizon
The name comes from the fact that even electromagnetic radiation (e.g. light) is unable to escape, rendering the interior invisible.

they are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole.

A black hole is a large gaseous body(Star) that collapsed into it's self and became a neutron star; which again collapsed on it's self to form what we know as a black hole. Stars collapse on themselves when they run out of fuel, and neutron stars collapse onto themselves when their own gravity is too great for them.

A place where gravity is so strong that even light cannot escape

a spot of infinite density and gravity called a singularity that sucks in everything including light.

it is when the star/sun explodes it causes a black hole that sucks in everything don't know what happens to it. they reckon soon in a very long time from now black holes suck the hole universe but we are talking billions of years past earths lifetime. when our sun explodes there will be a black hole.don't know why they turn to black holes

black holes are caused when a star runs out of their fuel and turn into a blackhole.
for exsample
the sun is made out of hydrogyn and helium and in 5 billion years it is going to run out and become a black hole that will kill evrything in sight.
