The Trapped False-Vacuum Fraction at Percolation and the Energy It Withholds From the Plasma

At percolation the false-vacuum fraction is 0.712, and even at the late stage I = 2 more than thirteen percent of space remains unconverted; genuine completion to the one-percent level requires I = 4.5, where the fraction is 0.0111. The withheld shares at percolation are 0.065 of the total energy for a strength of 0.1 and 0.356 for a strength of unity. In other words, an estimate that spends the whole latent heat at percolation overstates the immediately available fluid energy by roughly a third of the latent component in the strong case. The withheld energy is not lost; it arrives as the pockets collapse, which stretches the effective source duration while lowering its early amplitude, a trade that simple one-number amplitude formulae do not represent. This study is simulated and computed from stated assumptions; it is not a measurement.
