How far would you have to travel to find another Earth? One with the same temperature, the same oceans, the same countries... and eventually, the same room and the same person sitting inside it? Anthony Aguirre follows that thought experiment to its strange conclusion: what happens if the universe is infinite?

Causal Sets : The quantum theory that predicted dark energy

LATEST VIDEO | March 17, 2026
What if the key to understanding dark energy was predicted decades ago? This video explores Causal Set Theory, a bold approach to quantum gravity that reimagines spacetime as fundamentally discrete—and may offer surprising insights into the accelerating universe, fine tuning the Big Bang, black holes and more Featuring leading theorists such as Rafael Sorkin, Yasaman Yazdi, Fay Dowker, Sumati Surya, and Niayesh Afshordi, we dive into the origins, predictions, and implications of this fascinating theory.
