No, "illustrated", not "demonstrated". The move Gravity is fictional and 
the space debris depicted were computer generated.

No, tiny bits of space debris burn up in the atmosphere, and so are not 
a threat. It is the bits which remain in orbit which are the problem.

Scientists at the ANU Institute for Space, on top of Mount Stromlo, are 
building a laser to target space junk. Yes, they really do wear while 
coats, in a facility which looks like a Bond villain's lair, on top of a 
mountain, and are working on a Laser Cannon. ;-)
