Abstract: This is an ongoing review on the idea that the phase space information lossat causal horizons is the key ingredient of major physical laws.Assuming that information is fundamental and the information propagates withfinite velocity, one can find that basic physical laws such as Newton-s secondlaw and Einstein-s equation simply describe the energy-information relationdE=TdS for matter or space time crossing causal horizons. Quantum mechanicsis related to the phase space information loss of matter crossing the Rindlerhorizon, which explains why superluminal communication is impossible even withquantum entanglement. This approach also explains the origin of Jacobson-sthermodynamic formalism of Einstein gravity and Verlinde-s entropic gravity.When applied to a cosmic causal horizon, the conjecture can reproduce theobserved dark energy and the zero cosmological constant. Quantum entanglement,path integral, and holography are also natural consequences of this theory.
