Mysteries of the Universe: Black hole and Worm hole

What is a black hole?
a black hole is a region of spacetime. The gravity there is is so strong that nothing can escape from its pull.
Is black hole really a 'hole'in space?
No it's not a hole. Black hole is an object like any other object in space but it's extremely dense.
And because of its extreme density it has an extreme gravity, everything including light is pulled towards it.
Then why do we call it as a black 'hole' ?
As mentioned in the above lines it has an extreme gravity because of its extreme density,everything that falls into it is trapped forever ,that's why it is term as a 'hole'.
What happens when we try to go inside a Black hole?
If a human tries to go inside a Black hole his body will be torn apart because of its extreme gravity.
What is a wormhole?
just imagine wormhole as a tunnel that has two ends at different points in space.
Is travelling through a wormhole possible?
Yes,something that falls into a wormhole can go through it to the other end.
But there is no evidence for the existence of a wormhole yet.

These online encyclopaedia is called a search engines. A search engine is a program that searches the internet and finds web pages based on the keywords that you provide. Most popular of them is Google. In 1995, Larry Page and Sergey brin agreed to write a program for a search engine. They build a server network using cheap,used and borrowed personal computers. And then it lead to the path to the creation of Google. But the attempt for licensing the product was a failure. Nobody wanted to take the risk of investing in an advanced product at an early stage of development. Andy Bechtolsheim ,the co founder of sun microsystems appeared as a saviour. He was impressed by the quick demonstration of Google. Google Inc. finally came into being in 1998. Its mission is to organise the world's information and make ...
