Are Some Things About the Universe Fundamentally Unknowable? (forbes.com)

StartsWithABang writes: As we peel back the layers of information deeper and deeper into the Universe's history, we uncover progressively more knowledge about how everything we know today came to be. The discovery of distant galaxies and their redshifts led to expanding Universe, which led to the Big Bang and the discovery of very early phases like the cosmic microwave background and big bang nucleosynthesis. But before that, there was a period of cosmic inflation that left its mark on the Universe. What came before inflation, then? Did it always exist? Did it have a beginning? Or did it mark the rebirth of a cosmic cycle? Maddeningly, this information may forever be inaccessible to us, as the nature of inflation wipes all this information clean from our visible Universe.

I was referring to the fact that he actually was begging the question, but 'First there was everything' was the question he was begging. Irregardless was thrown in to poke fun at the people who think it's about grammar.

There is one thing

The only thing that is fundamentally unknown is the question of fundamental unknowability itself.

Many things are fundamentally unknowable

There's an infinite number of unknowable facts. I think "fundamentally" is sort of a semantic trick that makes it seems like there's a distinction with a difference even when there might not be one. Exampe: my friend crashed his bike and had retrograde amnesia for a few hours. What caused the crash is unknowable. Although it could have been observed, it just wasn't. There's no way now to go out and capture those photons, long since scattered and reabsorbed, etc. The path he was on has been totally repaved and redesigned. What happened to him is just as unknowable to human beings as esoteric facts about the early universe, the real difference is that bike accidents are mundane and the early universe is interesting.
