When this happens, the much smaller size of the star's envelope signals a new balance between greatly increased gravity and radiation pressure.

There is now a stable balance between gravity and pressure.

Subsequently, other physicists began to explore links between gravity and entropy.

Einstein noted that no experiment done inside the ship could distinguish between "real" gravity and the force of acceleration.

He is known for his work on the connection between gravity and thermodynamics.

The nuclear-burning processes in the heart of any star are a delicate balance between pressure and gravity.

They are inherently simple, their formation being governed by a rather straightforward competition between quantum mechanics and gravity.

Eyfells' creative drive is to document the interaction between time, space and gravity.

Ultimately there is a direct contest between internal gravity and the tidal forces.

The jaw was broad under the ears, but going to a pointed chin, the mouth wide, poised between humor and gravity.
