If gravity is so weak, then why is it so fundamental? We cannot see it, but we can see its effects. I would say that someone who considers gravity a weak force in the universe falls into the category that I mentioned in one of my previous posts.... the one that states people who think they know everything don't. There is so much about the universe that we don't know that for any one to make any definitive conclusions about anything would be a naivety of epic proportions.

Gravity is very weak. I mean think about it- EVERY object has a gravitational field, but the only one you notice day-to-day is the Earth's. A space shuttle with chemical rockets can produce three to four times as much force with those as the entire mass of the earth can produce in gravity!
Black holes are an exception because they have such a ridiculous amount of mass in a tiny space.
