I have nowed ya since you was a sack boy and I can understand your concern that a carelessly discarded bobby pin could be the precursor to external extinction.
However, I would seek to assure you and indeed the entire membership of A2K that the quoted figure of 300,000,000 miles a second is somewhat in excess of the true measured speed of light, which is 186.000 mps.
I do believe that Vette was confusing miles with metres!
BTW the earth orbits at nearly 30 kilometres per second, or 67,000 mph.
As it will take over 100.000 years for light to cross the Milky Way, you will have plenty of time to enjoy a BBQ this evening without the fear of catastrophe.
To answer your question as to why the needle wouldn't burn up... as nothing travels faster than light, the heat couldn't catch up.
The question remains however, what is the speed of 'Dark' when there is no light?
