Persinger, M.A. (Learn how and when to remove these template messages) This article needs attention from an expert in Physics. The forgotten cause is to be found in the various sources of energy producing movement, in experimental settings in which, especially, the contamination with radon is not checked. The problem of an enormously large energy density of the quantum vacuum is discussed in connection with the concept of renormalization of physical parameters in quantum field theory.

The cosmological constant problem Steven Weinberg Theory Group, Department ofPhysics, University of Texas, Austin, Texas 7871Z Astronomical observations indicate that the cosmological constant is many orders of magnitude smaller than estimated in modern theories of elementary particles. With the cosmological constant established, the vacuum catastrophe is presented as a compelling conﬂict between the two pillars of modern physics: GR and quantum mechanics. ^ W Nernst. ; 65 (9), 927 (1997));, The American Journal of Physics" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.

INTRODUCTION AND HISTORY The cosmological constant originates from the Einstein ﬁeld equations of general relativ-ity. This article has multiple issues. Read "Response to S. R. Ovshinsky and H.

It will be argued here that the cosmological constant problem exists because of the way the vacuum is defined in quantum field theory. J. Phys. It will be argued here that the cosmological constant problem exists because of the way the vacuum is defined in quantum field theory. Persinger, M.A. We address the ~122 orders of magnitude discrepancy between the vacuum energy density at the cosmological scale and the vacuum density predicted by quantum field theory. J. Phys.

In fact, QFT gives us an exact value for how much energy empty space should have.

(2009) A Simple Estimate of the Mass of the Universe: Dimensionless Parameter A and the Construct of Pressure. Physicist: The vacuum catastrophe is sometimes cited as the biggest disagreement between theory and experiment ever.. We argue that the discrepancy between the Planck mass scale and the observed value of the cosmological constant can be largely attenuated, if those quantities are understood as a result of effective, and thus scale-dependent, couplings. The calculated vacuum energy is a positive, rather than negative, contribution to the cosmological constant because the existing vacuum has negative quantum-mechanical pressure, and in general relativity, the gravitational effect of negative pressure is a kind of repulsion. Bose-Einstein condensates, the creeping behaviour of helium, and the Casimir Effect happen to be particularly simple to explain. For other uses, see Vacuum catastrophe (disambiguation).
