Horizon: Super Massive Black Holes
Crikey. Even the title scares the life out of me.
It gets worse once the programme actually starts. One of the strengths of good science programmes - like Horizon - is that they manage to turn science into stories. Sometimes it’s a detective story, sometimes a scary story but always a story. And a story that keeps you glued to the very end. Forget tripe like EastEnders - give me something like this:
So these super-massive black holes (SMBHs from now on or my fingers will drop off) - not super, not massive but super and massive - are really very, very big indeed. In fact, they are between 1 million and 1 billion times bigger than the standard black hole.
And the standard black hole is a frightening enough thing. Caused by the ongoing contraction of its own matter the black hole - previously a star, now dead - becomes smaller and smaller and increasingly dense. Its gravitational pull becomes super-strong, pulling in gas from nearby stars, literally stripping them of all substance. Such is the intense pull of a black hole’s gravity that light itself cannot escape - hence its blackness. The more the black hole consumes the more massive - and therefore the more strong - it becomes. For me, black holes are the ultimate nightmare scenario. In my fevered imagination, one could drift by earth and simply relieve it of its atmosphere. That would be the end of us all.
You can’t see a black hole because it’s black. And it’s a hole. But you know they’re where they are by the effects they have on surrounding matter - other stars particularly. What scientists first discovered was a really big one - a SMBH - in the middle of a galaxy and it was quite a find in the world of cosmology. So they decided to look for some more.
