Is it not a bit odd to consider things that will happen long after the sun is a cinder "scary." There are enough genuinely scary things that could flash-sterilize the planet, or smash a big enough hole in it to end all complex life forms. Nearer-term scary things are likely to come from how poorly humans can adapt to long term life in space or on planets with different gravity. Time stretches beyond the ability of life to survive in both directions. Nobody will be around to be scared.
