Very interesting. They demonstrate good evidence of the existence of black holes in every galaxy that they have looked at. This shows that every galaxy has a black hole.

They present strong evidence for a correlation between the speed of the outer stars of a galaxy, and the black hole that is now thought to be within the center of every galaxy. The theory is that the speed could only be correlated to the size of the black hole if the matter in the stars was once in contact with the black hole.

So there is now strong evidence that galaxies form through an initial formation of a black hole. First, gas collides and collapses into a black hole. Then the hole sucks up all the matter within reach. Eventually, it pushes off the rest of the matter of the galaxy, and this matter turns into stars, which in turn turn into higher elements, planets, and in our case, life.

So every thing started out as black holes. Some of the holes become dorminant as the suck up everything near them, others are active, when matter approaches.

We can now determine the size of a black hole in a galaxy, by at least two processes: the first, - black holes appear to be 1/2 of a percent of the size of the galaxy they reside in. Two: the speed of the outer stars are faster the larger the size of the black hole.

We now have a good idea of how galaxies formed.

No god need apply.

Very interesting documentary and I agree with todangst that it presented good evidence for the existence of supermassive black holes in all galaxies.

However...

I think the documentary was a little over dramatic... Great use of music from the films "Predator" and "Aliens" though. Also, I can now say that I've seen extremely dramatic music come to a shattering climax as a scientist writes "-1" on a chalkboard.

That has got to be the most expensive bit of useless information I have ever contemplated.
