1. I suppose that before the end of the century, people will be able to take trips in the space. Maybe common space trips will start to happen as soon as 2100, 2150 or so.
2. I can't see that before certainly 2050, and that's optimistic. My guess would be 2100 at the earliest.
3. Another century and it should be done.
4. Terraforming is something that can't happen in less than several millenium probably. I believe it is something that will become possible with time & our advancement, but I would imagine it will take another set of 1000 years before we'd have done it. Maybe the year 10,000? It's a psychological step
5. I believe that with technology, we will be able to contain the rise of the sun's temperature up to a point. However, 10% per billion years, that gives us maybe just a billion of years to get out of here! Unless some event (asteroid impact, ...) sends us into a "winter", or ice age, 10% increase of temperature is a lot, and my wild guess would be that just a few millions of years will be enough to make life here very difficult.
6. Yes. Just when is a very rough guess, but I said above maybe in 10,000?
7. Undecided, but why not? Titan looks like a primitive earth, so... in a few billion years, who knows what's there? I'd say it's a possibility.
8. Yes. Definitely. I believe that we will develop the means to ensure our continued existence.
9. Beyond doubt to me. We will then be just another race in space. Black, white, asian, etc., that will mean nothing. There won't be anymore of Asia or Africa anyways!
10. Most likely. Who knows, maybe it's happening already?
