Kaon Condensation, Black Holes and Cosmological Natural Selection

TL;DR

This paper discusses how certain astrophysical observations, like neutron star masses, could challenge theoretical predictions about kaon condensation, vector meson behavior, and the implications for cosmological natural selection.

Contribution

It links observational data on neutron stars to fundamental predictions in nuclear physics and cosmology, testing the validity of several theoretical models.

Findings

Massive neutron stars or significant mass differences could falsify key predictions.

Observations can challenge theories of kaon condensation and vector meson behavior.

Implications for the maximum neutron star mass and cosmological natural selection are discussed.

Abstract

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 > 2 M_sun would put in serious doubt or simply falsify the following chain of predictions: (1) nearly vanishing vector meson mass at chiral restoration, (2) kaon condensation at a density n ~ 3 n_0, (3) the Brown-Bethe maximum neutron star mass M_max ~ 1.5 M_sun and (4) Smolin's `Cosmological Natural Selection' hypothesis.
