Stephen Hawking, Who Brought Cosmology to the Masses and Championed Progressive Causes, Dies at 76

Visionary physicist Stephen Hawking, a leading explorer of the cosmos and champion of progressive causes, died early on Wednesday, March 14, at the age of 76.

Hawking was known for his research into properties of black holes, gravity, and Einstein’s theory of relativity, which he wrote about in his best-selling 1988 book A Brief History of Time, a work that was credited with sparking the general public’s interest in cosmology.

“Not since Albert Einstein has a scientist so captured the public imagination and endeared himself to tens of millions of people around the world,” Michio Kaku, a professor of theoretical physics at the City University of New York, told the New York Times.

The scientist was diagnosed with amyotrophic lateral sclerosis (ALS) at the age of 21, and was told by doctors that he would die within three years. Instead, he embarked on an influential career, eventually using a wheelchair when he lost his mobility and a speech synthesizer to communicate.

Along with his discovery of phenomena such as Hawking radiation, the theory of energy flowing into and out of a black hole until it fades to nothing, Hawking was a fierce opponent of the war conservatives waged on science in recent years.

“No one created the universe and no one directs our fate. This leads me to a profound realisation that there probably is no heaven and no afterlife either. We have this one life to appreciate the grand design of the universe and for that, I am extremely grateful.”—Stephen Hawking

He condemned the so-called “debate” over climate crisis and was sharply critical of President Donald Trump’s decision in 2017 to withdraw the U.S. from the Paris accord on climate change.

“We are close to the tipping point where global warming becomes irreversible,” he said last summer. “Trump’s action could push the Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, and raining sulphuric acid.”
