Abstract
Information is fundamental to the physics of the Universe and we can indeed realize John Wheeler's dream. This is exemplified by unearthing a missing link of Einsteinian gravitation from a foundational analysis of some physical information, which appears revolutionary. It is realized that the introduction of the cosmological constant was not the `biggest blunder' Einstein ever made. Rather it was the introduction of the energy-stress tensor in his equations through which the source of gravitation/curvature is represented. This became the source of various problems, inconsistencies and unsolved puzzles in his theory, which are generally overlooked. It is shown that the energy-momenta-angular momenta of the gravitational and the material fields are built-in ingredients of the geometry of the so-called `vacuum' field equations and the energy-stress tensor is a redundant part of Einstein's equations. Baffling as it may seem, nevertheless the new discovery appears as a linchpin for understanding many unresolved problems in a unified manner. Moreover, the new paradigm gets strong support from observations ranging from the solar system to the Universe without requiring the usual epicycles of the standard theory, such as inflaton, non-baryonic dark matter and dark energy.
