Does the ocean show that there’s always more to learn, or that we can never know everything?

I think it’s wonderful that there are mysteries still to be discovered.

I agree with @janbb .

“Will we ever?”
– At this rate, we’ll be lucky to survive the century, so I think not.

New finding everyday show that we can never know everything. It could be in the Ocean, Space or right in front of our eyes.

Yes, there’s always more to learn, and also, we can never know everything.

We live on a little known planet. We will never know everything about it and we still have a lot to learn.
