DonaldTurner,

Re "Heat is molecular motion, so presumably the absence of molecular motion, absolute zero, really is the coldest cold"

Yep, that's my take on it, too.

Re "I suppose that molecular motion would be limited by the speed of light,"

It's not the speed, it's the average energy per particle, and that approaches infinity as a particle's speed approaches lightspeed.

Case researchers may have solved information loss paradox to find black holes do not form
"Nothing there," is what Case Western Reserve University physicists concluded about black holes after spending a year working on complex formulas to calculate the formation of new black holes. In nearly 13 printed pages with a host of calculations, the research may solve the information loss paradox that has perplexed physicists for the past 40 years.
(And here I thought a paradox was having Crusher and Polaski in the room at the same time... )

Physicist explores what happened before the Big Bang
New discoveries about another universe whose collapse appears to have given birth to the one we live in today will be announced in the early online edition of the journal Nature Physics on July 1 and will be published in the August issue of the journal's print edition. "My paper introduces a new mathematical model that we can use to derive new details about the properties of a quantum state as it travels through the Big Bounce, which replaces the classical idea of a Big Bang as the beginning of our universe," said Martin Bojowald, assistant professor of physics at Penn State.

Particle Physics

"administratium." Administratium has been found to have no protons or electrons, thus having an atomic number of 0. It has, however, 1 neutron, 125 assistant neutrons, 75 vice neutrons and 111 assistant vice neutrons, giving it an atomic mass of 312. These 312 particles are held together by a force that involves the continuous exchange of mesonlike particles called morons.

The morons are surrounded by vast quantities of leptonlike particles called peons. Since it has no electrons, administratium is inert. However, it can be detected chemically as it impedes every reaction with which it comes into contact. According to the discoverers, a minute amount of administratium caused one reaction to take more than four days to complete when it normally could have occurred in less that a second.

Administratium has a half-life of approximately three years. However, it does not decay in the usual way but instead undergoes a reorganization in which a portion of the assistant neutrons, vice neutrons and assistant vice neutrons exchange places.

In reorganization, some of the morons inevitably become neutrons, forming new isotopes. This characteristic of moron promotion leads some scientists to speculate that administratium is formed spontaneously whenever moron concentration reaches a certain level. This hypothetical quantity is referred to as Critical Morass.
