EVERYTHING COMPUTES. “The Californian philosopher John Searle argues that even your garden wall is a conventional computer; and other philosophers maintain that a simple rock standing motionless on a beach is a (conventional) computer.” https://lnkd.in/eepengBW View in LinkedIn

DARK MATTER EXISTS. “Thus, there must be other kinds of matter/energy with which the Universe can map out its spacetime geometry to a finer spatial accuracy than is possible with the use of only conventional ordinary matter. We conclude that a dark sector necessarily exists in the Universe!” https://lnkd.in/eA85pA5X View in LinkedIn

DARK ENERGY. “The above discussion leads to the prediction of dark energy.” https://lnkd.in/eA85pA5X View in LinkedIn

INFORMATION IN COSMOS. “We have also shown that the Universe contains I ∼ (RH/lP)2 bits of information (∼10(120) for the current epoch).” https://lnkd.in/eA85pA5X View in LinkedIn

DUAL NATURE. “These long-wavelength bits or “particles” (quanta of spacetime HH foam) carry negligible kinetic energy. (Note: Such long-wavelength quanta 3 can hardly be called particles. We will simply call them “particles” in quotation marks.).” https://lnkd.in/eA85pA5X View in LinkedIn

TRIANGULATION. “Since pressure (energy density) is given by kinetic energy minus (plus) potential energy, a negligible kinetic energy means that the pressure of the unconventional energy is roughly equal to minus its energy density, leading to accelerating cosmic expansion, in agreement with observation.” https://lnkd.in/eA85pA5X View in LinkedIn

HYPOTHETICAL DARK ENERGY. “This scenario is very similar to that of quintessence, but it has its origin in the holographic spacetime foam.” https://lnkd.in/eA85pA5X View in LinkedIn

MATHEMATICAL UNIVERSE. “I argue that with a sufficiently broad definition of mathematics, it implies the Mathematical Universe Hypothesis (MUH) that our physical world is an abstract mathematical structure. I hypothesize that only computable and decidable (in Gödel’s sense) structures exist, which alleviates the cosmological measure problem and may help explain why our physical laws appear so simple.” (Professor Max Tegmark, MIT). https://lnkd.in/emNRh22t View in LinkedIn
