The Evolution of Science Fiction discussion

I found this question among a list of the biggest questions in science: Can we ever know everything about the universe--or must some of it's mysteries always remain beyond our reach?

Gödel's incompleteness theorems suggest there is no chance.

My more or less intuitive sense of things is that humans are quite limited creatures who could never get anywhere near knowing everything.

When you consider that we use so little of our brain power & that even the smallest things have immeasurable complexity, there is absolutely no chance whatever. I see a huge lack of intellectual curiosity in people in general, and even if that's present, the initiative to do something with it is not.

Given that the universe is expanding away from us in all directions at a rate that increases with distance, there is no way we can know everything about the universe.

The finite speed of light plus the accelerating expansion of space sets fundamental physical limits on what we can observe or measure. Of course we might be able to infer properties of the unobservable universe using math and physics, but direct empirical knowledge of the total universe will be permanently out of reach.

You all make very good points!
