 They say the sun is going to burn out in billions of years. Do you think mankind will make it there, or what will be our demise? Thank you. Well, not on this planet, no. I don't think it'll make it on this planet. As far as what would be our demise on this planet, look, I think it's one of three things. I suppose it could be a number of things, including a pandemic or something along those lines, but there's usually somebody that's going to survive even the worst pandemic, the worst plague.
