Well, clearly that's possible. What is it with people on HN coming up with "gotchas" regarding topics they know nothing about?
He didn't say there could not ever be equations that show "nothingness turning into somethingness", all he says is that we have no way of showing it with what we know, what we can deduce, and much less what we can prove. If there are equations that satisfy the constraints, we're not aware of them yet (the same way we don't know yet how to combine general relativity and quantum mechanics). According to our current understanding, "the universe did not spring into existence, it has always existed, though perhaps not in its current form".
If you want to suggest random ideas, maybe you want to back them up with more than just "but what if they do exist?"
