Great wagers in physics history

Two of the most powerful words in science might just be “Wanna bet?”

While science usually makes progress through rigorous research, testing, and verification, sometimes a hunch — and a little friendly competition — can push scientists to keep digging for the truth.

The time-honoured tradition of scientific wagers adds stakes (usually very, very low stakes) and levity to the scientific process.

A bet led Isaac Newton to write what would evolve into his masterwork, Principia. Stephen Hawking might be the world’s most famous present-day scientist, but that doesn’t mean he knows all the answers: despite numerous wagers, he has a terrible win-loss record.

Said Hawking’s colleague John Preskill, who has won some of these bets: “Although Stephen Hawking is without doubt a great scientist, he’s a bad gambler.” (To Hawking’s credit, many believe he deliberately makes long-odds wagers in order to bring attention to interesting scientific debates.)

Here are some of the greatest wagers — some settled, some still outstanding — in physics history.

Perhaps the most amazing thing about our universe is that humans are capable of figuring out how it works. While plenty of mysteries remain, we have used logic and experiments to make sense of much, and we discover new things every day. How much do you know about the amazing universe we live in? Take […]
