3. What is a black hole? A black hole is an object so compact that its gravitational is strong enough to prvent light or anything else from escaping.
   What is inside a black hole? We cannot glimpse whats inside a black hole because light cannot reflect back, which makes it completely black inside and impossible to see in or out.
   Do black holes live forever? Since nothing from a black hole can escape, black holes eventaully evaporate, which slowy retuns energy back to the planet.
