Kaon condensation, black holes, and cosmological natural selection

, : Kaon condensation, black holes, and cosmological natural selection. Physical Review Letters 101(9): 091101-091101

It is argued that a well-measured double neutron-star binary in which the two neutron stars are more than 4% different from each other in mass or a massive neutron star with mass M > or approximately 2M(middle dot in circle) would put in serious doubt or simply falsify the following chain of predictions: (1) a nearly vanishing vector meson mass at chiral restoration, (2) kaon condensation at a density n-3n0, (3) the Brown-Bethe maximum neutron-star mass Mmax approximately 1.5M(middle dot in circle), and (4) Smolin's "cosmological natural selection" hypothesis.

One successful mechanism of seed dispersal in plants involves production of edible fleshy structures which attract frugivorous animals and transfer this task to them. Not only Angiosperms but also Gymnosperms may use the fleshy fruit habit for see...
