10,000 years isn't much. I don't see why we would leave earth in 10,000 years. We'll colonize other planets, sure, but we'll be the same people, we won't even evolve much. If you want to ask a theoretical question like that, try 1,000,000 years at least.
I'm planning to paint my wall. By that I mean I want to make an actual painting, such as a landscape across the with of my entire wall. The idea is simple, I choose and image, cover the wall with the primer, and I paint it with the same paints that people use to paint their walls. I'm planning on buying a half a liter or more of each of the primary colors, and then just mix them. My question to anybody willing to read this is; will it work? Is it possibly a bad idea to use the same paints that people simply color their walls with? Or should I just paint it like I'm painting on canvas or paper?
