Theory of general relativity (GR) has been scrutinized by experts for almosta century and describes accurately all gravitational phenomena ranging from thesolar system to the universe. However, this success is achieved provided oneadmits three completely independent new components in the energy-stress tensor$T^{\mu\nu}$$-$inflaton, dark matter and dark energy, which though do not haveany non-gravitational or laboratory evidence and have remained generallyspeculative. Moreover, the dark energy poses a serious confrontation betweenfundamental physics and cosmology.  The present situation reminds us of Einstein's `biggest blunder' when heforced his theory to predict a static universe, perhaps guided by his religiousconviction that the universe must be eternal and unchanging. It seems that weare making a similar blunder by forcing $T^{\mu\nu}$ into the field equationswhile the observations indicate that it is not needed. We seem to have adeep-rooted conviction that the spacetime will remain empty unless we fill itby the energy-stress tensor. However, we have been ignoring numerous evidencesearnestly indicating otherwise.  From a critical analysis of the present situation, we develop an entirely newinsight about the source of curvature in equations $R^{\mu\nu}=0$ which, thoughmay appear orthogonal to the usual understanding, is in striking agreement withall known phenomena in GR. Moreover, it answers some hitherto unexplainedpuzzles and circumvents some long-standing problems of the standard paradigm.
