Abstract
Law of conservation of energy is the most well-established law of modern physics. But, inflationary cosmological model which assumes the universe to be created from a point of singularity has not been able to identify the source of energy for creation of this universe. As per uncertainty principle, a quantum vacuum fluctuation can at most create energy of ~10-8 kg in a Planck time of ~5.4 ×10-44 s whereas total positive energy due to matter/vacuum existing in the universe is more than ~1054 kg. To solve this problem, we have recently published a new cosmological model (Biswaranjan Dikshit, Canadian Journal of Physics, 100, 218-225, [2022]) in which we have mathematically proved that the total energy of the universe can be zero right from the beginning of the universe to till date due to negative gravitational potential energy and thus law of conservation of energy can be satisfied during creation of the universe from nothing. In this article, starting from a simple argument, we explain why net energy of the universe can be zero only in our model, not in standard cosmological model. An interesting fact pointed out in this paper is that the factor ~1062 by which radius of universe has increased from its starting value of ~10-36 m to present value of ~1026 m is same as the factor by which positive energy has increased from Planck energy ~10-8 kg to present value ~1054 kg. This is in agreement with our new model that predicts the positive energy of universe to be proportional to the radius of universe. We also bring out to the notice that zero energy universe is possible only if smallest possible length in nature is, lmin=lp(π/2)1/2 = 2.0×10-35 m. Minimum possible length is important in theory of quantum gravity and string theory.
