Consider a system of energy $E$ and size $R$ falling into a black hole, and let $\Delta S_{BH}$ be the resulting change in black-hole entropy. Bekenstein bound conjecture. The seco…

Let $S=A/(4G\hbar)$ be the Bekenstein–Hawking entropy of a black hole with mass $M$ and horizon area $A$. Entropy–mass bound conjecture. The entropy should satisfy … with equality…
