Might the proton decay in other places or at other times?

Does the proton decay? While this was a famous prediction of Grand Unified Theories (GUTS) developed in the 1970s and 1980s, experimentalists have ruled it out—or rather, put lower limits on its mean lifetime of about 1034 ...

How warp drives don't break relativity

Somehow, we all know how a warp drive works. You're in your spaceship and you need to get to another star. So you press a button or flip a switch or pull a lever and your ship just goes fast. Like really fast. Faster than ...

Would we know if a supernova was about to hit the Earth?

We know that regular supernovas pose no existential threat to life on Earth in the near-term. But there are other varieties of supernova that are a little bit harder to predict, and a little bit harder to spot.
