When a star collapses to a black hole, from the outside it never quite gets there. Everything that ever falls in reaches the horizon together, at the end of time. What follows isn’t destructi…

A geometric proof that black holes remain finite in size/density, and the event horizon occurs as the next moment after the universe.

A story about the main reasons I now think the universe expands because collapsed matter must continue as an expanding cosmology, the expansion is the collapse read from the other side, and the rat…

A friend’s question about an Eddington–Finkelstein diagram sent me looking for a better explanation, and I found a cycloid. Eighteen papers later, here is what came of it: horizons that are n…

Headline: What, exactly, is a black hole? Black holes are the most enigmatic, intriguing, captivating, confusing and confounding objects in all of physics. In fact, despite decades of focused researc...
