This disagreement is known as the cosmological constant problem or the “vacuum catastrophe”. ; 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. Read "Response to S. R. Ovshinsky and H. Fritzsche’s “Comment on ‘Vacuum catastrophe; An elementary exposition of the cosmological constant problem’ ” (Am. ^ W Nernst. Bose-Einstein condensates, the creeping behaviour of helium, and the Casimir Effect happen to be particularly simple to explain. 1 The Cosmological Constant Problem 1.1 A Classical Ambiguity In the eld equation for General Relativity, R 1 2 Rg + g = 8ˇGT ; (1.1) there is an ambiguity: the cosmological constant, , is not xed by the structure of the theory.1 There is no formal reason to set it to zero, and in fact, Einstein famously
63 (7): 620-626, 1995. has been cited by the following article: Article. American Journal of 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 Vacuum and the Cosmological Constant Problem Gerald E. Marsh Argonne National Laboratory (Ret) 5433 East View Park Chicago, IL 60615 E-mail: geraldemarsh63@yahoo.com Abstract. ISBN 0471713473. 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. They disagree by a factor of at least 10 107.. 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.
I. 63 (7): 620–626. 2005: 63. (2009) A Simple Estimate of the Mass of the Universe: Dimensionless Parameter A and the Construct of Pressure. (Learn how and when to remove these template messages) This article needs attention from an expert in Physics. 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. American Journal of Physics, 63, 620-626.

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. This article has multiple issues. Adler, R.J., Casey, B. and Jacob, O.C. According to quantum field theory the energy of empty space can’t quite be zero. American Journal of Physics, 63, 620-626. In fact, QFT gives us an exact value for how much energy empty space should have.
