Remembering Stephen Hawking, a mind that opened the universe

The theories of the famous British physicist changed forever how we view black holes

Early Wednesday morning, physicist Stephen Hawking died at his home in Cambridge, England. He was 76. That number alone could be seen as remarkable.

At the age of 21, he learned that he had amyotrophic lateral sclerosis (ALS), a condition also known as Lou Gehrig's disease. It attacks the neuromuscular system, quickly making most movement impossible. Hawking's doctors gave him only a few years to live.

Not an end, but a beginning

But they were wrong. Though the disease did ravage his body, it could not touch his brilliant mind. Stephen Hawking revolutionized science from a wheelchair, becoming the most groundbreaking scientist since Albert Einstein. Using only his finger and cheek muscles to control a specialized computer and speech synthesizer, he communicated theories that changed science forever.

Before Hawking, gravity was the lone rule that governed the universe. Whether it be moons and comets, or stars and planets, each object's gravity kept things humming in orbit. But newer science at the time was showing that tiny atomic-sized particles had different rules, known as quantum physics. These rules were bizarre, full of jumping particles and bursts of seemingly unpredictable energy. Nothing like the stable gravity of the Sun.

Hawking's bold move was to try and blend the two ideas together. Many thought it was impossible. In the 1970s, he began combining ideas about the most massive and very smallest objects known. His goal was to create a theory of everything.

Hawking made this connection in his work on black holes. He found that black holes—those unstoppable matter- and light-sucking machines of the cosmos—actually gave off energy, too. Black holes give off energy?! It sounded impossible, but his calculations proved it.

The energy that they give off is now known as Hawking radiation. And the ideas he came up with led to a deeper understanding—and deeper curiosity—of how the universe works.

Still not an end

Stephen Hawking certainly didn't answer every question he asked of himself. Black holes are still full of great mysteries, ones that future brilliant minds can hopefully help unravel.

But he will be remembered as one of the truly great minds in human history. Despite disease, disability, and early brushes with death, his unstoppable mind led him to create ideas whose legacy will never die.

His theory of everything was never fully completed. But it is everywhere.
