The Search for Extra Dimensions in Particle Physics

Extra dimensions are a bold idea that space may have more than three dimensions.
String theory suggests there could be up to 10 or 11 dimensions.
These hidden dimensions might be curled up so small we can’t see them.
Extra dimensions could help unify gravity with the other fundamental forces.
The Large Hadron Collider (LHC) searches for signs of extra dimensions in collisions.
One clue would be energy “missing” from collisions, as particles slip into hidden dimensions.
Some theories propose that mini black holes at high energies could reveal them.
Extra dimensions might explain why gravity is so much weaker than other forces.
No evidence has been found yet, but experiments continue to test the idea.
Discovering extra dimensions would revolutionize physics and our view of the universe.
