10 Terrifying Theories About What's Hiding Inside Black Holes

Most of us picture the inside of a black hole as a single point of infinite density — but almost no physicist actually believes that anymore. From ring-shaped singularities and quantum Planck stars to fuzzballs, gravastars, and interiors somehow larger than the entire observable universe, we count down ten serious theories about what's really hiding past the event horizon. Each one is stranger than the last, and the final answer isn't an object at all — it might be the end of time itself. Sources: 10.
