The universe linked by cosmic information

Information is a quantity that springs up very naturally in the study of the universe as it is tied up with gravity. The theory developed by Prof. Padmanabhan of IUCAA and Dr. Padmanabhan of ETH Zurich ties together these two concepts, which were thought to be unrelated until now, and provides an explanation based on the flow of information in the universe. The heat source melts the ice around it, creating a region of water, which in turn expands, reaching local thermodynamic equilibrium… At large scales, close to the boundary of the phases, the molecules have not yet reached equilibrium, since the chunk of ice is being heated up from the inside.” Incredibly enough, this is similar to how our universe behaves. Replacing Big Bang “The region with water is analogous to the observed universe and it is surrounded by a pre-geometric phase which is described by - as yet unknown - laws of quantum gravity. The Big Bang is replaced by a transition from one phase to another at the boundary,” he explains The authors argue that the total cosmic information transferred from the early, quantum gravitational phase to the late, classical phase must be equal to four times pi.
