• What is a black hole?
• A black hole is an infinitely dense object that
  occupies a single point in space. It is so dense
  that not even light can escape from them.
• Why is it impossible to escape from a black hole?
• It is impossible to escape from a black hole
  because its immense density warps space,
  creating a gravitational pull that not even light
  can ignore. Thus making it a black hole.

• If we can not see a black hole how do we know
  they exist?
• We know they exist because we can see the effects
  of a black hole. We can see the cosmic jets that
  they generate as well as the objects they pull
  in.
• What are cosmic jets?
• A cosmic jet is a release of matter from the are
  surrounding a black hole. Cosmic jets move at
  almost the speed of light. However how they move
  this fast isnt really understood. It is believed
  that opposing magnetic fields play a key role

• How can something like a black hole be created?
• Scientists arent entirely sure. Because the
  changes in the universe happen so slowly, were
  talking in hundred of thousands of years maybe
  more, the process that forms a black hole has yet
  to be observed. However it is believed that when
  a massive enough star explodes it will then
  implode and due to the unbelievable power of that
  implodsion the star will collapse into a black
  hole.

• Okay why should we study black holes?
• Well aside from curiosity and a pursuit of
  knowledge, black holes could prove instrumental
  in improving our understanding of gravity. The
  conditions that a black hole creates allows
  scientists a natural laboratory where they can
  test out their theorems. This is important
  because well computer models can aid scientists
  there is still nothing like the real thing. Which
  is what black holes provide.

• White Holes, what are they?
• White holes are the opposite of black holes.
  Matter is continuously pushed away from a white
  hole, instead of being pulled in. They have been
  predicted by as of yet no evidence has been
  found.
• Well if theres no evidence, why have they been
  predicted?
• Mostly because of the fact that a similar
  mathematic equation describes electricity,
  gravity and magnetism. But so far only
  electricity and magnetism have been proven to be
  repulsive as well as attractive

• How are black holes and white holes related to
  wormholes?
• It is theoretically possible for a black hole and
  a white hole to connect and form a gateway.
  However both would have to be spinning holes.
  Which further complicates matters as then both
  would have to be electromagnetically in sync.
  Also no white holes have been found as of yet. It
  is also believed that any gateway would be too
  small for a human to use.
