[Physicist]

Here's the way I see it. There are an infinitude of things to know. Obviously we won't ever know them all, but if any given thing is understandable, we can (and will eventually) understand it if only we set our minds to it. If it's fundamentally not understandable--such as the ultimate question of "why does anything exist and not just nothing"--then pondering it won't get you any closer to the truth (religious claims to the contrary notwithstanding).

Not sure I go along with this.

What exactly do you mean by "understandable" or "knowable?" Knowledge that is provable?

I'm not trying to put words in your mouth, I'm asking.
