Four weird Stephen Hawking theories that turned out to be correct (and six we don’t know)

Stephen Hawking was one of the greatest theoretical physicists of our time. His illustrious 50-year career in science comes from his illustrious 50-year career in science, best known for his appearance in popular media and his lifelong fight against debilitating illnesses, and his true influence on his descendants.Starts with his PhD The dogma In 1966, his groundbreaking work continued non-stop until his finals. paper It was completed in 2018, a few days before he died at the age of 76.

Hawking worked at the intellectual cutting edge of physics, and his theory often seemed strangely distant when he formulated them. Still, they are slowly being accepted into the mainstream of science, and new supporting evidence is constantly emerging.From his astonishing point of view Black Hole In his account of the humble beginnings of the universe, there are some of his theories that have been substantiated here … and some are still in the air.

Big bang wins

Hawking got off to a breakthrough with his dissertation, written at a critical time when there was fierce debate between two rival cosmologies. big Bang And steady state. Both theories admit that the universe is expanding, but the first expands from a microscopic and ultra-dense state in the past finite time, and the second theory expands the universe forever. Is assumed. Matter It is constantly created to maintain a constant density.In him The dogmaHawking has shown that steady-state theory is mathematically self-contradictory. He instead claimed that the universe began as an infinitely small, infinitely dense point called the singularity. Today, Hawking’s explanation is almost universally accepted by scientists.

Black holes are real

Best of all, Hawking’s name is associated with Black Hole — Another kind of singularity. It is formed when the star completely collapses under itself. gravity..These mathematical curiosities arose from EinsteinGeneral theory Theory of relativity, And when Hawking turned his attention to them in the early 1970s, they had been debated for decades.
