Quantum Foam and Discrete Measures

Posted on December 7, 2012 by PlatoHagel

Physicists would dearly love to study this foam but there’s a problem. Spacetime only becomes foam-like on the tiniest scale, at so-called Planck lengths of 10^-35 metres or so. See: How to Measure Quantum Foam With a Tabletop Experiment An … Continue reading →
