Ifølge ... hvor var det jeg leste det igjen? ... så endte, var det Wigner?, opp med en overbevisning om at "everything is information" (etter å ha lagt fra seg overbevisningen om at "everything is energy"). Selv kom jeg til en lignende overbevisning når jeg lærte at [[Ikke-reversible kretser avgir varme]]. ### Crackpottery: [The mass-energy-information equivalence principle](https://pubs.aip.org/aip/adv/article/9/9/095206/1076232/The-mass-energy-information-equivalence-principle) Forfatteren lukter crackpot, men jeg er jo enig i tesen da. Han [påstår](https://www.indiegogo.com/projects/is-the-universe-a-simulation-let-s-test-it--2#/) at prinsippet kan forklare [[Mørk materie]], fordi: > Information (has) the characteristics of a scalar boson particle with no charge, no spin, no any other properties except mass / energy. (...) This led me to propose the radical idea that information might be the missing dark matter in the universe, and also to postulate that “information” is the fifth state of matter along solid, liquid, gas and plasma, and possibly the dominant form of matter in the universe. Denne [videoen](https://www.youtube.com/watch?v=xoMtlw-Ap38), repostet av forfatteren, lukter mer bogus enn noensinne. Noen highlights: > We all know there is no dark matter. (...) **Billions** have been spent. (...) Now for the first time ever, we have a physicist who posits that there is no dark matter at all—which we have known at this channel all along.
