"But since ALL of our understanding of nature comes from scientific studies, it is very reasonable to thing that these questions can also be answered by science."

That's all I'm asking....See how reasonable I am.

I do understand that in relation to the Universe, questioning minds have only been around for an infinitesimal amount of time. And eventually, science's level of understanding may catch up to my questions. But, I'll be dead by then. What's the harm in wondering, now?
It's pointless to wonder about the unanswerable questions of reality? So what if it's a pointless passtime? Could be a definition in and of itself of reality based on science as we know it...reality could be just a pointless passtime.
