assuming of course we survive.

I was watching Through The Wormhole last night. The subject was what in the world we will do when the sun expands and burns Earth to a crisp. Several interesting solutions based on what we know now were offered. It was all very interesting but it is also ridiculous to speculate on a problem that looms many billions of years in our future.

Certainly we will have had to survive several dozen extinction events before we deal with that problem

When the sun expands will we still populate Earth? Probably not. If we do, isn't it likely that our knowledge will be so far advanced that it will be unrecognizable to us today.

I have a hard time imagining humanity surviving for a billion years, much less as an uninterrupted civilization. If we do last that long, we will be unrecognizable and surely even a different species.

I hope we have an uninterrupted run and populate the universe. We will continue to learn because we will continue to change. We are a better humanity today than we were a hundred years ago. I think it is safe to say we will be even better in the future. Morality is not related to our ability to pursue knowledge. It may have something to do with our survival as a species but it has nothing to do with our need to learn and explore as long as we are around.
