From the post "Drag and A Sense of Lightness",
rec=q24πεomev2
and v2=2c2, also
recre=1−Amere
where A is the drag factor. Therefore,
rec=re−Amer2e
Amer2e−re+rec=0
re=1±√(−1)2−4Amerec2Ame
re=me2A{1±√1−4Amerec}
From the post "Temperature, Space Density And Gravity", it was postulated that electron and proton pair are matter and antimatter pair, when a electron collide into the nucleus, total annihilation occurs and huge amount of heat is produced.
re=me2A{1±√1−4Amerec}<rn
where rn is the radius of the atomic nucleus.
The drag factor is directly proportional to density, if space behave the same,
A=Aodsdn
where As is the drag factor of space at space density ds and Ao is the drag factor of normal free space, dn uncompressed. ds decreases with increasing T and so A decreases with increasing T. From the post "kaBoom",
ds−dn=B.h(lnT)
dsdn=E.h(lnT)+1=f(lnT)
where E=Bdn and f(lnT) is a function in lnT
then the condition for matter/antimatter annihilation is,
me2Aof(lnT){1±√1−4Aof(lnT)merec}<rn
Does the L.H.S decreases monotonously with increasing T? If it does then matter/antimatter annihilation is possible by increasing the temperature of a confined heavy element whose rn is large.
