The maximum computational speed of a self-contained system in the material universe, derived from Einstein's mass-energy equivalency and the Heisenberg uncertainty principle: it is approximately 1.36 × 10⁵⁰ bits per second per kilogram. This value is important in designing cryptographic algorithms that can never be cracked by brute force.

Japanese Meaning
ブレーマン限界は、宇宙に存在する自己完結型物質システムが持つ理論上の最大計算速度を指します。これは、アインシュタインの質量エネルギー等価性とハイゼンベルクの不確定性原理に基づいており、約1.36×10⁵⁰ビット/秒・キログラムという値が算出されます。この概念は、ブルートフォース攻撃によっていかなる暗号アルゴリズムも解読されないよう設計する際に、重要な指標となります。
