Author and scientist Maurice Cotterell spoke about his research into the enigmatic force of gravity, and its underpinnings on a molecular level. Gravity is not a fifth force but a manifestation of electromagnetic (EM) energy, a kind of "corkscrew" wave, he explained.

With the understanding of gravity as polarized EM radiation, a wave equal and opposite to the gravitational radiation could be used to overcome the force of gravity, he detailed. Such anti-gravity radiation could make interstellar travel a real possibility, but since our Sun controls fertility, migration to another planetary system would fail, Cotterell declared.
