gravity **

After all, they were on top of the gravity well.

The high gravity, the hours in one position, had no effect on her.

The gravity is a point or two less than we have known.

Could something similar be at work here, like a gravity field, perhaps?

The gravity of the situation began to press on him.

"I thought the gravity of the situation would focus your attention."

The gravity seemed to be set at about Earth level.

For the time being he had gravity on his side.

We're getting out of here on gravity drive at once.

They live under red light and about half again Earth's gravity.

I must make him see the gravity of his position.

The going became more difficult as gravity began to work against him.

For the moment, however, his body was held by little more than gravity.

I'm saying she lives in a world whose center of gravity is herself.

All he needed was to cut the power and let gravity take over.

They were used to working in a deep gravity well.

The man at the top of the well has gravity working for him.

Despite the gravity of the problem, I believe there is an answer.

In short, it was very serious business when the gravity went out.

Again, gravity does most of the work in moving us forward.

But we'd never have to do it in full Earth gravity.

"Why does everybody believe in the law of gravity then?"

The gravity of this situation was not lost upon him.

Gravity was a fact, a simple physical law, a force of nature.

He asked the question with such gravity; like a child.
