Consider the Star Trek transporter, a staple of science fiction for converting matter into energy, beaming it at the speed of light to a new locale, then reassembling the bits into their previous form.
Theoretically, manipulating a Higgs field would be one way to turn a person into energy and make them “disappear.” The hard part would be putting them back together again.
“The only reason why the particles around us, and that make us up, are bound is because of the Higgs field,” Krauss said. “They have mass. If the Higgs field were to go away, then the particles would all of a sudden move at the speed of light.
