non-sequitur, literally meaning "it does not follow", from:
(1) When the Big Bang is described as the event during which the cosmos went through a superfast "inflation," expanding from the size of an atom to the size of a grapefruit in a tiny fraction of a second (as shown in Jackhammer's original post:

I imagine the universe as having consisted of an infinite space full of those tiny atom-sized areas expanding.
(2)
The universe would then be an infinite space where expansion occurs at every point within that space.
(3) If
the universe at the time of the Big Bang was an infinite space of dense matter and expanded at every point within that space, then we would have something without limits that expands yet isn't actually getting "larger" because
the space was infinite to begin with.
I've boldfaced the parts that I can't follow. It wasn't just matter expanding during the Big Bang, it was space itself (which she later remarked about).
