Yes, the death of our sun is a very long way out, but it's also entirely certain and unavoidable. It's a hard deadline. We could very easily kill ourselves off in a million ways before that happens and there is plenty of other threats in space that could do it for us without warning at any moment, but those are all only possibilities. The end of Earth and everything on it at some point in the future due to the death of our sun is a certainty and there's nothing we know of that can prevent or allow us to survive it. > You might as easily argue for saving money on oversized fireworks and solving teleportation first. Oversized fireworks seem unlikely to save us, but if teleportation becomes more promising than traveling through space in ships I'm all for it. Right now, it looks like ships are our best bet and so that's where we should be spending more of our limited and increasingly vanishing time and resources. It's a good idea that we continue to look into alternatives, we just want a greater percentage of our resources/efforts spent on whatever seems the most likely to work.
