Stephen Hawking: Google Doodle pays tribute to the legendary scientist on his 80th birthday

Google honored English cosmologist, novelist, and theoretical physicist Stephen Hawking with an animated film on its site on Saturday, his 80th birthday. Hawking’s life and achievements are chronicled in this film, which includes a voiceover by the physicist himself, created with his family’s permission.

He once remarked, “My objective is simple.” “It is a comprehensive knowledge of the cosmos, why it is the way it is, and why it exists at all,” says the legend.

Stephen Hawking, born in Oxford, England, has always been captivated by the cosmos. He was diagnosed with a neurological condition at 21, which restricted him to a wheelchair over time. He lost his speech ability and had to rely on a speech-generating gadget to communicate. “One of history’s most influential scientific brains,” according to Google.

Hawking received a BA in Physics from Oxford University and a Ph.D. from the University of Cambridge. He was fascinated with black holes, which he used as the basis for his studies and investigations. He found that particles might escape black holes in 1974, which is regarded as his most significant contribution to physics.

One of Hawking’s most well-known theories is that black holes slowly regurgitate information about all the stuff they’ve consumed but in a confused form known as Hawking radiation. Stephen Hawking postulated in 1974 that a black hole’s event horizon emits energy. Because energy can be transformed into mass and vice versa (as Albert Einstein’s famous equation E=MC2 demonstrates), releasing all of that energy into space would cause the black hole to shrink. It will eventually run out of mass and vanish.

If you’re not a quantum physicist, the mechanics of why black holes generate energy in the first place may be a bit confusing. However, the gravity of a black hole is so powerful that general relativity (the set of laws that describes how gravity works) and quantum mechanics (the set of principles that describes how subatomic particles behave) collide near the event horizon, causing strange things to happen to particles.

Under the right circumstances, background energy in the cosmos may be converted into two particles: one matter and one antimatter. Usually, when these two particles clash, they annihilate each other, and the cosmos returns to a pleasant, comfy balance. However, half of the pair may fall into the hole near a black hole’s event horizon while the other half escapes. According to Hawking, the departing particle is discharged back into space as energy.

In 1997, 23 years after the first notion in a paper, Hawking and his colleagues argued how Hawking radiation functioned.

Hawking rose to prominence in the late 1980s due to his ability to explain physics to non-physicists. A Brief History of Time (1988), The Universe in a Nutshell (2001), and Brief Answers to the Big Questions are among his eight works (2018). He and his daughter Lucy Hawking also co-wrote a series of children’s novels, starting with George’s Secret Key to the Universe (2007).

And he completed most of it after being informed he only had two years to live in 1963. Hawking began to stumble more often during his last year as an undergraduate student at Oxford University, and his speech started to slur. ALS, or amyotrophic lateral sclerosis, was diagnosed during his first year as a Ph.D. student at Cambridge University. In other words, the motor neurons in Hawking’s brain and spinal cord that sent commands to his muscles were deteriorating. Doctors estimated that he had around two years to live at the time.

“At 21, my aspirations were lowered to none,” he stated. “Everything that has happened since then has been a bonus.”

ALS ultimately disabled Hawking, and he earned a reputation for driving his wheelchair as rashly as he’d driven his rowing crew at Oxford, where his predilection for hazardous tactics had ruined a few boats.

When Hawking’s disability prevented him from speaking, he used a speech-generation gadget. Initially, he used a portable joystick to enter words and letters into the computer, but subsequently, he controlled the system by twitching a single cheek muscle. It took a long time to put together a phrase this way, but Hawking used it to write scientific articles and whole books. His family granted Google permission to replicate his voice for today’s Google Doodle.
