Following the Big Bang, our universe expanded at an exponential rate. According to this theory, known as cosmic inflation, the explosive growth produced tiny quantum fluctuations that later evolved into galaxies. Cosmic inflation neatly explains how our universe got so large and mostly homogenous, and that’s why it’s remained a strong theory in cosmology for decades. But it’s far from …

For mathematical convenience, he assumed that there’s an unlimited variety of particles—an unrealistic assumption that makes some physicists wonder whether this third layer matches reality (with its 17 or so known particles) any better than the second layer does. “We don’t have an infinite number of …

If Neptune gets knocked out of its orbit by just 0.1%, it could cause turmoil in the cosmos. Astronomers used a telescope in Hawaii to find a new object on the outer edges of our solar system, helping to fuel evidence of a long-standing theory about Planet Nine, or Planet X. For years, scientists have theorized about a ninth planet …
