きっかけはビッグバンの高熱状態では磁気単極がおおくつくられすぎてしまう問題を
解決しようとしたものだったという。
グースの論文を探すのもめんどうくさいので
どういうわけかとたからないままほおっておいたが
すでにWikipedia で解説してあった。
つまり、ビッグバンでの膨張速度を何桁もあげて、最初の温度を下げてしまえば
磁気単極の生成が減るだろうというものであった。
Magnetic-monopole problem[edit]
The magnetic monopole problem (sometimes called the exotic-relics problem) says that if the early universe were very hot, a large number of very heavy[why?], stablemagnetic monopoles would be produced. This is a problem with Grand Unified Theories, which proposes that at high temperatures (such as in the early universe) theelectromagnetic force, strong, and weak nuclear forces are not actually fundamental forces but arise due to spontaneous symmetry breaking from a single gauge theory.[31] These theories predict a number of heavy, stable particles that have not yet been observed in nature. The most notorious is the magnetic monopole, a kind of stable, heavy "knot" in the magnetic field.[32][33] Monopoles are expected to be copiously produced in Grand Unified Theories at high temperature,[34][35] and they should have persisted to the present day, to such an extent that they would become the primary constituent of the universe.[36][37] Not only is that not the case, but all searches for them have failed, placing stringent limits on the density of relic magnetic monopoles in the universe.[38] A period of inflation that occurs below the temperature where magnetic monopoles can be produced would offer a possible resolution of this problem: monopoles would be separated from each other as the universe around them expands, potentially lowering their observed density by many orders of magnitude. Though, as cosmologist Martin Rees has written, "Skeptics about exotic physics might not be hugely impressed by a theoretical argument to explain the absence of particles that are themselves only hypothetical. Preventive medicine can readily seem 100 percent effective against a disease that doesn't exist!"[39]

物議をかもしだしそうな記述が満載だ。
そのひとつはもしインフレーションでノーベル賞をあげるとしたら
だれにあげるかインフレーションに寄与すたトップ３はだれかという
問題だ。ノーベル賞はもはや賞金は少ないといえるもブランド力は
残っているからね。
この点でWikipedia 解説のなかで
佐藤勝彦はプライオリテイでもインフレーション全体のなかでの
位置でも不利になっている。
この解説のなかでは
グースとリンデが際立っている。
Hu はインフレーションには直接の関係はなく
Bモード偏光での寄与だ。
Hu は別格かもね。
