And yet, that information is not forthcoming, and those hypotheses effectively infinite.

"Guilty secret" is an uncharitable reading of the parent post, I'd say more out of the realm of scientific inquiry and more the philosophical. It's like asking "what was there before time existed?" - the scientific answer is null because that's a nonsense question - "before" implies the existence of a "time" to count it.

And yet, if the universe suddenly exists at T+0:00, it'll be impossible for science to understand the conditions at T-0:01 because that information does not exist given consensus understanding of time.

Still, we can comprehend the concept of "before time existed" on some abstract level, but the sciences cannot, absent some external source of information that a scientist must necessarily reject until it appears.
