Yahoo: Does quantum gravity exist? A new experiment has deepened the mystery
An astronaut can hold a tool in space, loosen their fingers, and watch it stay put. Nothing drops. Nothing tugs downward. Yet the brain does not simply forget gravity because the body has left Earth.

MSN: Does quantum gravity exist? A new experiment has deepened the mystery
A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...
Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth.
A new satellite mission sheds light on Earth's gravity field and provides clues about changing sea levels.
Data from NASA satellite observations provide information about Earth's mean gravity field and inform monthly maps of the time-variable gravity field, both of which are useful tools for scientists as they study the planet's changing climate.
GRAVITATIONAL PULL See Gravity GRAVITY The force of attraction between two objects which is influenced by the mass of the two objects and the distance between the two objects. GYROSCOPE A heavy wheel or disk mounted so that its axis can turn freely in one or more directions. A spinning gyroscope tends to resist change in the direction of its axis.
