Claim 1: “When two objects are brought extremely close together—just a few hundred nanometers apart—heat doesn't simply radiate away in the usual sense. Instead, it can tunnel across the gap through electromagnetic waves”
VERIFIED
The concept of near-field radiative heat transfer (NFRHT) occurring between objects separated by distances smaller than the wavelength of thermal photons (nanoscale gaps) is confirmed by multiple scientific search results.
