Why is it that light cannot escape from black holes? Is light made of matter? Does gravity affect light?

What if the whole point of our existence is to expedite the acceleration of the converging of the universe to a single point?

If gravity pulls everything into a point in space, then the intelligence of the universe would have as its goal the convergence of all matter. Perhaps we are one of the vehicles that accelerate this convergence by our own manipulation of substance. We create products out of the raw material around us. We alter its form, its density, and its combinations. What if we are the advanced form of this substance learning how to manipulate substance so we can, so far unconsciously, expedite the acceleration project?

Any thoughts on the matter?

Please, no "nobody knows the answer" idiots. These kind of people are just waisting everyone's time, and have completely missed the boat on what the Yahoo Answers forum is all about.

Two boys standing on a bridge each throw a rock straight down into the river below. They throw the rocks at the same instant but one rock hits the water before the other. How can that happen since the acceleration (due to gravity) is the same in both cases?

I have a 7.5 amp 115 volt AC motor, that I plan on running from a 12volt DC battery using an inverter.

http://www.dcacpowerinverters.com/itemdesc.asp?CartId={BF4E353E-9C78EVEREST-403C-B331-1D16835C5F18}&ic=PW900-12

My 12volt battery says that it has 5 amp hours, so does that mean I wouldn't be able to run the motor? If not, or if I could only run it for a short time, what would be a better solution for a fairly cheap battery system to power this motor?
