Planetarium Talks: Extra dimensions and microscopic black holes

Although Einstein’s general theory of relativity precisely describes the properties of gravity, it is not clear why gravity is so much weaker than the other fundamental forces of nature. The weakness of gravity could be explained, however, by speculative theories that predict spatial dimensions in addition to the three dimensions we experience in our everyday live. One spectacular way of revealing these extra dimensions would be through the formation of microscopic black holes, which, if there are extra dimensions, might be produced at the Large Hadron Collider. Microscopic black holes would be harmless, but their discovery would revolutionize our physical world picture.
