Scientific wager

Last updated

A scientific wager is a wager whose outcome is settled by experiment or observation, following the scientific method. It typically comprises a commitment to pay out when a currently-unknown or uncertain statement is resolved, and either proven or disproved. Some wagers have specific date restrictions for collection, but many are open. Wagers occasionally exert a powerful galvanizing effect on society and the scientific community.

Notable scientists who have made scientific wagers include Stephen Hawking and Richard Feynman. The Stanford Linear Accelerator has an open book containing about 35 wagers in particle physics dating back to 1980; many are still unresolved.

Notable scientific wagers

There are many examples of scientific wagers from the past two centuries, many related to large-scale questions in science at the time.

In 1870, Alfred Russel Wallace bet a flat-Earth theorist named John Hampden that he could prove the flat Earth hypothesis incorrect. The sum staked was £500 (equivalent to £62,000in 2023). [1] A test involving a stretch of the Old Bedford River, in Norfolk, was agreed on: Wallace measured the curvature of the canal's surface using two markers separated by about 5 km (3 mi) and suspended at equal heights above the water's surface. Using a telescope mounted 5 km from one of the markers, Wallace established that the nearer one appeared to be the higher of the two. An independent referee agreed that this showed the Earth's surface to curve away from the telescope, and so Wallace won his money. However, Hampden never accepted the result and made increasingly unpleasant threats to Wallace. This test is now known as the Bedford Level experiment.

In 1975, cosmologist Stephen Hawking bet fellow cosmologist Kip Thorne a subscription to Penthouse for Thorne against four years of Private Eye for him that Cygnus X-1 would turn out to not be a black hole. In 1990, Hawking acknowledged that he had lost the bet. Hawking's explanation for his position was that if black holes did not actually exist much of his research would be incorrect, but at least he would have the consolation of winning the bet. [2]

In 1975, Michael Sipser wagered an ounce of gold with Leonard Adleman that the P versus NP problem would be solved with a proof that P≠NP by the end of the 20th century. Sipser sent Adleman an American Gold Eagle coin in 2000 because the problem remained (and remains) unsolved. [3]

In 1978, chess International Master David Levy won £1250 (equivalent to £7,500in 2023) [1] from four artificial intelligence experts by never losing a match to a chess program in a ten-year span from 1968 to 1978.

In 1980, biologist Paul R. Ehrlich bet economist Julian Lincoln Simon that the price of a portfolio of US$200 (equivalent to $700in 2023) [4] of each of five mineral commodities (copper, chromium, nickel, tin, and tungsten) would rise over the next 10 years. He lost, and paid the amount the total price had declined: $576.07 (equivalent to $1,300in 2023). [4] See: Simon–Ehrlich wager

In 1997, Stephen Hawking and Kip Thorne made a bet with John Preskill on the ultimate resolution of the apparent contradiction between Hawking radiation resulting in a loss of information, and a requirement of quantum mechanics that information cannot be destroyed. Hawking and Thorne bet that information must be lost in a black hole; Preskill bet that it must not. The formal wager was: "When an initial pure quantum state undergoes gravitational collapse to form a black hole, the final state at the end of black hole evaporation will always be a pure quantum state". The stake was an encyclopaedia of the winner's choice, from which "information can be recovered at will". [5] Hawking conceded the bet in 2004, giving a baseball encyclopaedia to John Preskill. Thorne has not formally conceded. See: Thorne-Hawking-Preskill bet

In 2000 roughly 40 physicists made a bet about the existence of supersymmetry, to be settled in 2011, but because the Large Hadron Collider was delayed the bet was extended to 2016. As of summer 2016 there had been no signs of superparticles, and the losers delivered "good cognac at a price not less than $100" each to the winners (equivalent to $130in 2023). [6] [4]

From 2000 to 2003, scientists placed bets on the number of genes in the human genome in a sweepstakes known as GeneSweep organised by Ewan Birney. [8] [9] [10]

In 2005, British climate scientist James Annan laid bets with global warming denialists concerning whether future temperatures will increase. Two Russian solar physicists, Galina Mashnich and Vladimir Bashkirtsev, accepted the wager of US$10,000 (equivalent to $15,000in 2023) [11] that the average global temperature during 2012–2017 would be lower than during 1998–2003. [12] The bet ended in 2017 with a win to Annan. Mashnich and Bashkirtsev did not honour the bet. [13] Previously, Annan had directly challenged Richard Lindzen. Lindzen had been willing to bet that global temperatures would drop over the next 20 years. Annan says that Lindzen wanted odds of 50–1 against falling temperatures. Lindzen, however, says that he asked for 2–1 odds against a temperature rise of over 0.4 °C. [14] Annan and others state they have challenged other denialists to bets over global warming that were not accepted, [15] including Annan's attempt in 2005 to accept a bet that had been offered by Patrick Michaels in 1998 that temperatures would be cooler after ten years. [16] Annan made a bet in 2011 with astrophysicist David Whitehouse that the Met Office temperature would set a new annual record by the end of the year. Annan was declared to have lost on January 13, 2012. [17]

In 2005, The Guardian columnist George Monbiot challenged Myron Ebell of the Competitive Enterprise Institute to a £5,000 bet (equivalent to £8,000in 2023) [1] of global warming versus global cooling. [18]

On July 8, 2009, at a FQXi conference in the Azores, Antony Garrett Lisi made a public bet with Frank Wilczek that superparticles would not be detected by July 8, 2015. [19] On August 16, 2016, after agreeing to a one-year delay to allow for more data collection from the Large Hadron Collider, Frank Wilczek conceded the superparticle bet to Lisi. [20]

In 2012, Stephen Hawking lost $100 (equivalent to $130in 2023) [4] to Gordon Kane of the University of Michigan because of the Higgs boson discovery. [21]

Zvi Bern has won many bets connected to quantum gravity. [22] In 2016 David Gross lost a wager about supersymmetry, but he continues to believe in the theory. [6] In 2017, Daniel J. Bernstein made a bet for US$2,048 (equivalent to $2,500in 2023) [11] with Francisco Rodríguez-Henríquez that quantum computers will publicly break the RSA-2048 factoring challenge no later than 2033. [23] In 2023, John Preuß Mattsson bet $2,050 that the challenge will withstand quantum computing until at least 2050. Daniel J. Bernstein, John Sahhar, Daniel Apon, and Michele Mosca accepted the bet. [24]

In 2021 Alexander Kusenko lost a $10,000 wager to Derek Muller over the possibility of sailing directly downwind faster than the wind as documented on Muller's channel, Veritasium. [25] [26] [27]

<span class="mw-page-title-main">Black hole</span> Object that has a no-return boundary

A black hole is a region of spacetime where gravity is so strong that nothing, not even light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. A black hole has a great effect on the fate and circumstances of an object crossing it, but it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.

The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region – such as a light-like boundary like a gravitational horizon. First proposed by Gerard 't Hooft, it was given a precise string theoretic interpretation by Leonard Susskind, who combined his ideas with previous ones of 't Hooft and Charles Thorn. Susskind said, "The three-dimensional world of ordinary experience—the universe filled with galaxies, stars, planets, houses, boulders, and people—is a hologram, an image of reality coded on a distant two-dimensional surface." As pointed out by Raphael Bousso, Thorn observed in 1978, that string theory admits a lower-dimensional description in which gravity emerges from it in what would now be called a holographic way. The prime example of holography is the AdS/CFT correspondence.

The Simon–Ehrlich wager was a 1980 scientific wager between business professor Julian L. Simon and biologist Paul Ehrlich, betting on a mutually agreed-upon measure of resource scarcity over the decade leading up to 1990. The widely-followed contest originated in the pages of Social Science Quarterly, where Simon challenged Ehrlich to put his money where his mouth was. In response to Ehrlich's published claim that "If I were a gambler, I would take even money that England will not exist in the year 2000" Simon offered to take that bet, or, more realistically, "to stake US$10,000... on my belief that the cost of non-government-controlled raw materials will not rise in the long run."

<i>A Brief History of Time</i> 1988 book by Stephen Hawking

A Brief History of Time: From the Big Bang to Black Holes is a book on theoretical cosmology by the physicist Stephen Hawking. It was first published in 1988. Hawking wrote the book for readers who had no prior knowledge of physics.

Hawking radiation is the theoretical thermal black-body radiation released outside a black hole's event horizon. This is counterintuitive because once ordinary electromagnetic radiation is inside the event horizon, it cannot escape. It is named after the physicist Stephen Hawking, who developed a theoretical argument for its existence in 1974. Hawking radiation is predicted to be extremely faint and is many orders of magnitude below the current best telescopes' detecting ability.

Richard Siegmund Lindzen is an American atmospheric physicist known for his work in the dynamics of the middle atmosphere, atmospheric tides, and ozone photochemistry. He is the author of more than 200 scientific papers. From 1972 to 1982, he served as the Gordon McKay Professor of Dynamic Meteorology at Harvard University. In 1983, he was appointed as the Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology, where he would remain until his retirement in 2013. Lindzen has disputed the scientific consensus on climate change and criticizes what he has called "climate alarmism".

In black hole theory, the black hole membrane paradigm is a simplified model, useful for visualising and calculating the effects predicted by quantum mechanics for the exterior physics of black holes, without using quantum-mechanical principles or calculations. It models a black hole as a thin, classically radiating surface at or vanishingly close to the black hole's event horizon. This approach to the theory of black holes was created by Kip S. Thorne, R. H. Price and D. A. Macdonald.

In theoretical physics, the anti-de Sitter/conformal field theory correspondence is a conjectured relationship between two kinds of physical theories. On one side are anti-de Sitter spaces (AdS) that are used in theories of quantum gravity, formulated in terms of string theory or M-theory. On the other side of the correspondence are conformal field theories (CFT) that are quantum field theories, including theories similar to the Yang–Mills theories that describe elementary particles.

Micro black holes, also called mini black holes or quantum mechanical black holes, are hypothetical tiny black holes, for which quantum mechanical effects play an important role. The concept that black holes may exist that are smaller than stellar mass was introduced in 1971 by Stephen Hawking.

<span class="mw-page-title-main">Black hole information paradox</span> Puzzle of disappearance of information in a black hole

The black hole information paradox is a paradox that appears when the predictions of quantum mechanics and general relativity are combined. The theory of general relativity predicts the existence of black holes that are regions of spacetime from which nothing—not even light—can escape. In the 1970s, Stephen Hawking applied the semiclassical approach of quantum field theory in curved spacetime to such systems and found that an isolated black hole would emit a form of radiation. He also argued that the detailed form of the radiation would be independent of the initial state of the black hole, and depend only on its mass, electric charge and angular momentum.
