Virtual Graviational Dipoles




Randy discusses what the Cosmological implications of a negative gravitational mass would be with Jim. If there were a negative gravitational mass (as opposed to inertial mass), then every time that an electron-positron pair was created in the vacuum, that would create a gravitational dipole. This in turn would create effects similar to dark matter, dark energy, and a cosmological constant -- and this in turn would have an effect on the origin of the universe.

Quantum Metaphysics

What's really behind all the strange phenomena and obtuse mathematics found in quantum mechanics?

Jim and Randy discussed this before the last published episode of PhysicsFM as a warm up after a hiatus and as a preview for episode 9: Quantum Cats. Discussing the same ideas in general with reference to a chapter of Quantum Mechanics and the Particles of Nature by Anthony Sudbury, which conveniently discussed four aspects of quantum mechanics that need interpreting and nine ways of interpreting them, some more objective than others.

Almost every belief about quantum mechanics can be described in one of these interpretations, and each of these interpretations have some adherents. And each of them, at some level are wrong.
