Fortunately Betelgeuse is far enough away that we ... probably ... don't have to worry about being affected by it going supernova.

We might have some pretty bright nights for a while, though.

Keeping in mind that "predict a collapse within a timeframe of human civilization" is based on an assumption that human civilization is about 10,000 years old.

One of my favorite classes in college was astronomy. I had this great disheveled-looking professor who explained everything so clearly. The expanding universe, for example, represented by x's on a balloon. The x's/galaxies remaining fixed as the space between them increases, and he blew up the balloon.
