It remains 1 to some extent a theory, but Doug has got as close as anyone to actually seeing it happen.It's started by getting alert on the computer that a supernova had gone off in a very nearby galaxy 2, only 210 million light years away, here is a picture of the supernova indicated by the arrow, and so what we immediately did was trawl through the Hubble space telescope archives just to see if we could find a picture of that exact spot in the sky taken before the star had actually exploded, and as luck would have it, someone did.
The image revealed that the supernova was the explosion of a star dubbed 3 LBV1 in a distant galaxy, Doug and his team realized that they had an unprecedented 4 opportunity because the star had been a super massive one, at least 50 times the mass of the sun, it was exactly the size to test out the theoretical equations, could this possibly be the birth of a black hole?
Two years we waited for all of the fireworks and embers of the supernova to disappear and go away, so that we could get a third picture, long after the supernova was gone to see if that star in fact had disappeared, and in fact it had, it was now gone, it was an extremely luminous 5 star, it blew up and now it was gone.
