The "many worlds" interpretation is just one, and there's still much work to be done on a system that succesfully combines relativity and quantum mechanics.

It's not that the matter is going faster than light, so much as the space is expanding faster than light.
"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." ~ Charles Babbage (1791-1871)
