Gravity is one variable in a lot of scientific processes. If you can remove gravity or minimize its effect, then you can understand the other processes that are going on.

I've been noticing gravity since I was very young.

It's only when gravity starts to take over you begin to think about your body.

The microgravity or the very, very low amount of gravity that we have up in space forces some changes in different processes. It forces changes in us as human beings.

I sometimes feel that we are losing an intuitive sense of our own bodies.

You may hate gravity, but gravity doesn't care.

It's embarrassing that we're in the 21st century and we don't even know what makes gravity work. I'm getting older and thinking maybe I should tackle more than the mundane. I may fail, but at least I will have tried.

We account for one-sixth of the forces of gravity we see in the universe. There is no known objects accounting for most of the effective gravity in the universe. Something is making stuff move that is not anything we have ever touched.

You can't blame gravity for falling in love.

We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.
