Planck relic
English
Noun
Planck relic (plural Planck relics)
- (physics, cosmology, astronomy, astrophysics, quantum mechanics, relativity theory) A spacetime singularity with an event horizon on the order of a Planck length (~ 10-35 metres), and a mass on the order of a Planck mass (~ 20 micrograms), whose only possible decay route is emitting a single photon of Hawking radiation of that rest mass as energy, but thus disallowed by quantum physics transition prohibition, which becomes stable and everlasting if it does not absorb anything.
