無限に熱くなったものはどのような色に見えるのか？
無限に熱くなったものはどのような色に見えるのか？ 色温度とは、光の色を K(ケルビン) という熱力学の温度を示す数値で表すもので、温度が高くなるにつれてオレンジ色から白、水色、と変化していきます。それをふまえて、「無限に熱いもの」を考えた時にはどのような色になるのか？という考察について数理科学の研究プロジェクト The Azimuth Project が公式ブログで解説しています。 The Color of Infinite Temperature | Azimuth https://johncarlosbaez.wordpress.com/2022/01/16/the-color-of-infinite-temperature/ 金属を高温で熱すると、赤やオレンジに光って見えるようになります。また、光をほぼ完全に吸収して反射しない 黒体 というものを想定したとき、ある温度において黒体が放射する光の波長が色として出てくることになり、それは高温になるにつれて赤からオレンジ、黄色、白と変化し、さらに高温になると水色から濃い青になるとのこと。 by Hołek この光を分析したスペクトルは、 レイリー・ジーンズの法則 に基づくとされます。この法則は、黒点が熱くなればなるほど近似値として正確なものとなるため、「無限に熱くした黒点」の色も予測できるとのこと。また、この法則によると色が温度に依存するのではなく、明るさが温度に依存して見え方に変化が起きています。 さらに、色の見え方には単純な物理学だけではなく、人間の知覚も関係します。パリの 国立高等電気通信学校 で講師を務めた デビッド・マドア 氏によると、レイリー・ジーンズの法則に対する人間の目の反応を解明することで、Windows環境でも基準となっている sRGB の色空間で想定の色温度を示すことができるそうです。 以上をふまえると、「無限に熱いものの色」はsRGBで(148,177,255)と示される以下のような色に近くなります。この色は恒星が超新星爆発して形成される典型的な 中性子星 の色であり、初期の宇宙の色でもあると解説されています。 ・関連記事 光の99.995％を吸収する素材が誕生し「黒さの世界記録」を更新、前世界1位の10倍以上の黒さ – GIGAZINE 光の98％以上を反射する「最も白い塗料」が開発される、白すぎて塗った物体が冷える – GIGAZINE あるはずのない光線が見える新たな錯視が報告される – GIGAZINE なぜ人の目は「青色」に焦点を合わせることが難しいのか？ – GIGAZINE 瞳孔のサイズは明るさだけでなく「知覚している物体の数」でも変化することが判明 – GIGAZINE […]
