After 30 minutes, the rat should have been dead. Sealed in a capsule-shaped chamber, the animal was breathing pure oxygen at a pressure high enough to cause a normal rat to have a seizure in five to 10 minutes. Dominic D’Agostino, a researcher at the University of South Florida, stood by, ready to flush the chamber with fresh air and rescue the creature at the first signs of a problem. But 30 minutes became 40 minutes, and still the rat appeared unbothered. At an hour, D’Agostino could only gaze at it on a video monitor with wonder. “The rat was just kind of staring back at us and grooming itself,” he says.

Shortly before placing the rat inside the chamber, D’Agostino had injected a new, one-of-a-kind molecule down the animal’s throat. Much of D’Agostino’s work is funded by the U.S. Department of Defense’s Office of Naval Research, and this experiment, which he conducted in mid-2011, was his first test of whether the new molecule could help a rat withstand an onslaught of oxygen. The hope was to one day do the same for Navy divers, who can experience devastating oxygen-toxicity seizures on deep dives.

In the pursuit of new knowledge, some scientists explore other worlds, discover new species, and develop cures for disease. Others film themselves being robbed by a colleague in a King Kong suit, to address a debate that’s been raging for more than 40 years.

Bedecked in ape cosplay, Satoshi Hirata from Kyoto University would grab a stone from his uncostumed colleague, Fumihiro Kano, and hide it under one of two boxes, all while Kano watched in mock indignation. Then, after Kano ducked behind a door, “Kong” would surreptitiously move the stolen stone to the second box. The duo filmed these shenanigans and then showed the videos to several chimpanzees, bonobos, and orangutans. They wanted to know how what the apes made of the scene. Specifically, when Kano returned and began looking for his stone, which box did the apes think he’d search first?

It is a strategy that President Donald Trump has deployed throughout his life, as instinctive and natural to him as the act of breathing: Villainize whoever is blocking his way.

Distasteful as Trump’s taunts might be, ridiculing adversaries has been the blunt-force instrument that propelled his political rise, with the president turning people into targets of scorn. As the impeachment fight enters its public phase, though, Trump faces a quandary. His go-to move may be inadequate in this moment for the very same reason the impeachment threat is so grave. There may be too many accusers who believe he shook down Ukraine, too many people who find fault with his behavior for the president to smack with a rhetorical mallet.

Democracy depends on the consent of the losers. For most of the 20th century, parties and candidates in the United States have competed in elections with the understanding that electoral defeats are neither permanent nor intolerable. The losers could accept the result, adjust their ideas and coalitions, and move on to fight in the next election. Ideas and policies would be contested, sometimes viciously, but however heated the rhetoric got, defeat was not generally equated with political annihilation. The stakes could feel high, but rarely existential. In recent years, however, beginning before the election of Donald Trump and accelerating since, that has changed.

Suppose that the biblical story of Creation were true: God created the universe in six days, including all the laws of physics and all the physical constants that apply throughout the universe. Now imagine that one day, in the early 21st century, God became bored and, just for fun, doubled the gravitational constant. What would it be like to live through such a change? We’d all be pulled toward the floor; many buildings would collapse; birds would fall from the sky; the Earth would move closer to the sun, reestablishing orbit in a far hotter zone.

Let’s rerun this thought experiment in the social and political world, rather than the physical one. The U.S. Constitution was an exercise in intelligent design. The Founding Fathers knew that most previous democracies had been unstable and short-lived. But they were excellent psychologists, and they strove to create institutions and procedures that would work with human nature to resist the forces that had torn apart so many other attempts at self-governance.
