Physicist and cosmologist Stephen Hawking is one of the few scientists in the modern world who has gained celebrity-like recognition and fan following. His death on March 14, 2018 sent waves of sadness throughout the scientific community as well as non-scientists who were his admirers. Despite a battle with ALS (amyotrophic lateral sclerosis), his desire to explore the universe extended his scientific knowledge to the rest of the world. From the formation of the universe to its possible end, Hawking made calculated predictions on it all.
Remembering him on his death anniversary, here are some groundbreaking findings that can be attributed to the phenomenal scientist and the inspiring human being.
Proving black holes
He was the first person to provide mathematical proof for the existence of black holes. They had been a theory before Hawking’s validation.
Hawking radiation
His prediction that black holes emit radiation has been held true and bears his name. Thanks to these predictions, we now know that black holes can vary in size depending on the energy radiation.
Hawking’s zone theorem
It was a team effort with Brandon Carter and James Bardeen. Together, they discovered the laws of black hole mechanics. The first of these was named after Hawking, who says the black hole never gets smaller in terms of its total area.
Black hole formation
In addition to finding out about their existence, Hawking also postulated how they were formed. When a star dies, all of its mass collapses to infinite density at a single point (or singularity) which in turn forms a black hole.
The theory of time
His theories on time are quite interesting. One of the many time-related theories he proposed was that before the explosion of the Big Bang (widely accepted as the event leading to the birth of our current universe), time was fundamentally nonexistent. This means that questions about “what happened or what happened before” this event are essentially meaningless.
