From: Bob Higgins Recently I have seen a couple of articles about temperatures below absolute zero and experimental evidence for this. Here is an example:
http://www.nature.com/news/quantum-gas-goes-below-absolute-zero-1.12146 This sounds a lot like Hotson's description of negative energy. Bob, Here is another take on negative (quantum) temperature - which fits well with observation. http://www.journaloftheoretics.com/Articles/3-1/calvet-final.htm Abstract: Conventional forces like gravitation and electromagnetism vary with the square of the distance. This is because the corresponding force is scattered into 3 dimensions due to the distribution of virtual gravitons or photons of the corresponding field in a 3D-space. In an analogous way, the Casimir force, that varies with the 4th power of the distance, ought to arise from bosons distributed in a hyperspace with 5 real physical dimensions. This leads to the prediction of a whole new world of “quantum temperatures” below zero Kelvin, and to a model that surprisingly agrees with cosmology and recent findings of the zero-point-field (ZPF). “Virtual” field particles (e.g. bosons of the ZPF) are probably nothing else than hyperspace particles that cross our 3-D universe from time to time, thus seeming “virtual” to us. This paper details how our universe can be considered as a 3-D space “floating” on an immense 5-D space - the hyperspace - in analogy to a sheet of ice floating in a deep sea.
