Is the Universe a Fluke? The Problem of Fine-Tuning
Modern physics grapples with why the universe's fundamental constants appear "fine-tuned" for existence, suggesting either a radical new theory or the reality of a multiverse.
Why Physicists Built an Experiment the Size of a Sea
Deep beneath the Mediterranean, a massive neutrino detector has captured a particle so energetic it could rewrite our fundamental understanding of the cosmos.
