Now this is really interesting, because you'd often see someone say, hey, you know, something for sure is going to happen, or something is impossible. But even a lot of the things that we think for sure are going to happen, there's some probability, or some chance that they don't happen. So for example, you might hear someone say, well, what's the probability that the sun will rise tomorrow? Well, you might say it's going to happen for sure. But you gotta remember, you know, some type of weird cosmological event might occur, some kind of strange, huge, planet-sized object in space might come and knock the Earth out of its rotation. Who knows what could happen. All of these have a very low, a very low likelihood, very, very, very, very, very low likelihood.
