The universe's expansion appears to exceed the speed of light, but this doesn't violate Einstein's laws. It's the stretching of space itself, not objects moving through space, that causes distant galaxies to recede faster than light. The expansion rate, unlike speed, doesn't have a universal limit.
The universe appears to be expanding faster than the speed of light, a phenomenon that seems to contradict Einstein's laws. However, this cosmic speedster doesn't break physics rules because it's space itself expanding, not galaxies moving through space. This mind-bending concept reveals the universe's true scale and dynamics.
The movie Project Hail Mary dives deep into real astrophysics and biology. It explores concepts like solar dimming, relativity, and alien life. While much is fiction, the film grounds its narrative in actual scientific principles, sparking curiosity about the universe.
In 1925, Werner Heisenberg's groundbreaking work laid the foundation for quantum mechanics, a theory that revolutionized physics but whose fundamental implications remain a profound mystery 100 years later. This exploration delves into the birth of this strange new physics.
In 1928, Paul Dirac's relativistic electron equation unexpectedly predicted the existence of antimatter. Initially met with skepticism, the discovery of the positron in 1932 confirmed this groundbreaking concept, revolutionizing our understanding of the universe.
