Singularities inside black holes are truly unavoidable (opens in new tab)

It’s easy to think about the idea of a singularity — where a large amount of matter and energy gets compressed into a single spacetime point or event — and dismiss it as a pathology. After all, everything that we know of in physics, at a fundamental level, comes in quantized little bits: particles and antiparticles with a fixed, finite amount of energy inherent to each of them. No matter what tricks you use, there are certain quantum properties that are always conserved and can never be creat...
