ATLAS Experiment CERN




We can only experience and therefore visualize the world in three space dimensions, even though it might well have more.

An indication for extra dimensions may be the extreme weakness of gravity compared with the other three fundamental forces (gravity is so weak that a common refrigerator magnet can pick up a paper clip overwhelming the gravity of the entire Earth). This weakness may be due to gravity's force field spreading into other dimensions.

The ATLAS Experiment may see evidence that extra dimensions exist via collision events in which a graviton particle disappears into other dimensions. ATLAS would detect a large imbalance of energy in the event.
