Niayesh Afshordi and Phil Halper, "Battle of the Big Bang: The New Tales of Our Cosmic Origins" (University of Chicago Press, 2025)

A thrilling exploration of competing cosmological origin stories, comparing new scientific ideas that upend our very notions of space, time, and reality.By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know …

Episode #188 – The Exhaust Principle

In 1973, Jacob Bekenstein, then John Wheeler’s graduate student at Princeton, demonstrated that a black hole’s entropy is proportional to its surface area, a formula that Stephen Hawking and Brandon Carter would later confirm despite setting out to disprove it. The result has been treated as a para…

What Would Multiple Universes Mean?

Is there more than one universe? According to current cosmology, our entire gigantic universe is only one of innumerable universes, each universe like one tiny bubble in a limitless ocean of universes. What could all this mean? Featuring interviews with Max Tegmark, Anthony Aguirre, Alan Guth, Andr…

Reality: Bigger, Stranger, and Probably Watching | 514

Reality may be bigger, stranger, and far more crowded than our three-dimensional monkey brains can handle. This week on Hysteria 51, we count down ten horrifying theories about what could exist in dimensions we cannot see, from shadow matter and hidden forces to holographic universes, colliding bra…

What Caused the Universe to Expand So Rapidly at the Beginning? - Cosmic Inflation and the Horizon Problem | Sleepy Facts About the Universe

The universe is 2.7 degrees above absolute zero in every direction we look, a remarkably uniform glow that presents a deep cosmological puzzle. In the standard picture of the Big Bang, distant regions of space have never been close enough to exchange light or heat, so they should not be in thermal …
