Did you know that if the sun disappeared, we would be thrown into space at the exact moment it was gone. If the sun went out, we would be an ice cube 8 minutes later, but if it disappeared the curvature of space/gravity that hold us in orbit would disappear and we would be on our own. We would all be dead, of course, but still, the planet would be flung into space. Kind of cool and interesting, don’t you think? I don’t know how the sun could disappear, however, so I wouldn’t lose any sleep over it.
