Blackholes! The law breakers of physics

Blackholes are something really incredible...The are the biggest mystery as they break the laws of physics often. Currently we see them as the heaviest object found. But you never know. Have we really understood universe. The answer is NO. There is a lot more to discover. Blackholes are also a base of natural time travel.
