English Dictionary

Planck relic

名詞

(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.

日本語の意味

プランク遺物：Planck長さ（約10⁻³⁵メートル）のオーダーの事象の地平線と、Planck質量（約20マイクログラム）のオーダーの質量を有する時空の特異点。ホーキング放射により1つの光子を放出することでのみ崩壊が可能なはずであるが、量子物理学における遷移禁止によりその崩壊が抑制され、何も吸収しなければ安定かつ永続的な存在となる対象を指す。

A Planck relic could, in principle, remain forever because its event horizon is on the order of a Planck length and its mass on the order of a Planck mass, while quantum transition prohibitions prevent it from decaying by emitting the single Hawking photon whose energy would equal its rest mass, leaving it stable unless it absorbs anything.

プランクスケールの時空遺物は、事象の地平線がプランク長さ程度で質量がプランク質量程度であり、崩壊に必要な質量に相当するエネルギーを持つ単一のホーキング光子の放出が量子遷移の禁止により禁じられているため、何も吸収しない限り理論上永久に存在し得る。
