We usually hear the terms "black hole" and "singularity" used interchangeably. Although a black hole is a singularity, it's not the only kind. A mathematical singularity just refers to the point where there's an infinite value of something. In a black hole, that point is where gravity and density go to infinity. But there are many more examples of singularities that are a bit more relatable to your everyday life. Watch the video below to learn about them.
