Born James Peebles, 2 others awarded Nobel Prize in Physics”

Two Americans and a Briton have won the 2019 Nobel Medicine Prize for discovering a molecular switch that regulates how cells adapt to fluctuating oxygen levels, opening up new approaches to treating heart failure, anaemia and cancer. While the discovery of exoplanets would have happened regardless of Mayor and Queloz-competing groups published results within a few years of their 1995 paper-they had the right hardware and planet to compel the astronomy community to accept the results.

Peebles, of Princetown University in the United States, was awarded the joint prize for "theoretical discoveries in physical cosmology".

Peebles was born in Winnipeg in 1935 and completed his undergraduate studies at the University of Manitoba.

This year's Laureates have transformed our ideas about the cosmos. "The Big Bang Theory" had its finale in May.

"I just kept going", Peebles said during a news conference, according to Princeton University. Indeed, the first planet they found, 51 Pegasi b, orbits a sun 50 light years away that heats its surface to more than 1,000 degrees centigrade, the award-giving academy said.

Three physicists have been awarded the 2019 Nobel prize in physics for groundbreaking discoveries of the evolution of the Universe.

Peebles made major theoretical contributions that improved the understanding of the universe, including the cosmic microwave background, dark matter, dark energy, and the Big Bang model. Over 4,000 exoplanets have since been found in the Milky Way. The prize ceremony will take place on December 10, on the anniversary of Alfred Nobel's death.

The 2019 Nobel Prize in Chemistry is expected to be announced Wednesday. And in 2017, alumnus Michael Landry [PhD/00] shared the Noble Prize in Physics for his work leading a team that observed gravitational waves, a phenomenon first predicted by Albert Einstein 100 years ago.

The Nobel Peace Prize will be handed out in Oslo, Norway, on the same day.

Kaelin Jr. shares the award with Peter J. Ratcliffe of the University of Oxford and the Francis Crick Institute, and Gregg L. Semenza of Johns Hopkins University School of Medicine, for the trio's "discoveries of how cells sense and adapt to oxygen availability".

And in a case of life imitating art, Tuesday's Nobel Prize announcement included the opening lyrics of "The Big Bang Theory" theme song: "Our whole universe was in a hot, dense state, then almost 14 billion years ago, expansion started".

"You should enter science because you are fascinated by it ... that's what I did".

Peebles thanked the Nobel committee for the award but said his advice to young people wanting to go into science would be not to be lured by the prospect of such prizes.

The announcement, October 8, 2019, that a trio of scientists had won the physics Nobel started off with an unlikely reference: the opening lines of "The Big Bang Theory".
