Gravitational constant
From Memory Alpha, the free Star Trek reference.
The gravitational constant, or G, is the universal constant of gravity, first discovered on Earth by the Human scientist Sir Isaac Newton. It played a large role in his theory of universal gravitation, in the following formula:
where Fg is the gravitational force between two bodies, m1 is the mass of one body, m2 the mass of the other body and r half the distance between the centers of the two bodies.
In 2366, when Q temporarily became Human and hoped to join the crew of the USS Enterprise-D, Geordi La Forge and Data asked him to assist in preventing the moon of Bre'el IV from crashing into the planet. Q suggested changing the gravitational constant of the universe. Although this was beyond the capabilities of the Enterprise crew, it did lead to one possible solution: extending the ship's warp field around the moon, thus reducing the moon's gravitational constant.
