"...Gravity might just be the manifestation of other forces---not a force itself, but the peripheral result of something else... So if gravity were an emergent force, It would mean that gravity isn't the central power pulling things to the Earth, but the tangential consequence of something else we can't yet explain. We feel it, but it's not there. It would almost make the whole idea of "gravity" a semantic construction. [Attributed to Brian Greene]"
