13.8 billion years? That's 3 x the age of the Earth, which is 4.6
billion years. Is that the best we can do? I'm not buying.

A minority view of the theorists (which I have recently seen but do
not have a citation) is that the universe is doubling in size per each
characteristic period T. I would amend that to "seen to be" doubling,
but in either case sets the universe's birthdate back a few googol.

[Mod. note: citations would really help move this discussion forward.
I know of no evidence to support this picture -- mjh]
