This model takes into account more than just the mass of the observable universe. While we previously found that the MOAC can brute-force a password with 306.76 entropy bits, this model allows the same for up to 405.3 bits.

Another well-known approach to calculating physical limits of computation is Bremermann's limit, which calculates the speed of computation given a finite amount of mass. This article's approach disregards time, focusing only on mass-energy equivalence.
