You are right.
The problem was that the lifetime of the Solar system is only 1/4 of a Maha Kappa.
– During a Maha Kappa there are four phases: duration of the Solar system (about 10 billion years), destruction of it (about 10 billion years), remaining in that state (about 10 billion years), reformation of the Solar system (about 10 billion years).
– Each of those four phases is 20 antakkappa.
I have revised the post, “31 Realms of Existence” to make that correction.
Thanks for pointing it out.
