How much information is in the universe? It’s an unfathomable number

Posted by in category: particle physics

This was described in his 2019 paper, “The mass-energy-information equivalence principle,” which extends Einstein’s theories about the interrelationship of matter and energy to data itself. Consistent with IT, Vopson’s study was based on the principle that information is physical and that all physical systems can register information. He concluded that the mass of an individual bit of information at room temperature (300K) is 3.19 × 10-38 kg (8.598 × 10-38 lbs).

Taking Shannon’s method further, Vopson determined that every elementary particle in the observable Universe has the equivalent of 1.509 bits of encoded information. “It is the first time this approach has been taken in measuring the information content of the universe, and it provides a clear numerical prediction,” he said. “Even if not entirely accurate, the numerical prediction offers a potential avenue toward experimental testing.”
