Energy in the Relativistic Theory of Gravity
arXiv:2202.11522 · doi:10.1142/S0219887822400072
Abstract
The more precise definition and the more fundamental understanding of the concepts of time, energy, entropy and information are building upon the new, relativistic foundation of gravity. This lecture is an attempt to explain the basic principles that underpin this progress, by focusing on the simple but subtle universal definition of energy. The principles are unearthed from Einstein's theory and Noether's theorems, beneath a century of misconceptions.
