Alternatively, you could get rid of the Higgs field, a field permeating all space that is generated by the infamous Higgs particle . "All elementary particles get their masses from their interactions with this field, kind of like being 'slowed down' by passing through a thick syrup," Overduin said. "If the Higgs field instead dropped to zero, the syrup would have no thickness and all elementary particles … would zip around freely and become massless." Having no mass, they'd be unable to curve space-time, so there would be no gravity. On top of that, they'd start moving at the speed of light, ditching the other particles they used to hang out with inside atoms.
