There’s no place like home—unless you’re Elon Musk. A prototype of SpaceX’s Starship, which may someday send humans to Mars, is, according to Musk, likely to launch soon, possibly within the coming days. But what motivates Musk? Why bother with Mars? A video clip from an interview Musk gave in 2019 seems to sum up Musk’s vision—and everything that’s wrong with it.

In the video, Musk is seen reading a passage from Carl Sagan’s book Pale Blue Dot. The book, published in 1994, was Sagan’s response to the famous image of Earth as a tiny speck of light floating in a sunbeam—a shot he’d begged NASA to have the Voyager 1 spacecraft take in 1990 as it sailed into space, 3.7 billion miles from Earth. Sagan believed that if we had a photo of ourselves from this distance, it would forever alter our perspective of our place in the cosmos.

It’s no exaggeration to say that one of the biggest artists in American music right now is a disgrace. Three weeks after the 27-year-old country singer Morgan Wallen said a racial slur on camera, his second studio album, Dangerous: The Double Album, is at No. 1 on the Billboard 200 chart. His singles have been bobbing in the country-music top 10 and the cross-genre Hot 100. Billboard’s ranking of the most popular artists in the United States had him in the top spot for five straight weeks. Thousands of people are, at this moment, streaming Wallen’s songs, buying his records, and watching his music videos—putting money in the pockets of someone who has admitted to saying one of the most noxious things imaginable.

Every day, more than 1 million American deltoids are being loaded with a vaccine. The ensuing immune response has proved to be extremely effective—essentially perfect—at preventing severe cases of COVID-19. And now, with yet another highly effective vaccine on the verge of approval, that pace should further accelerate in the weeks to come.

This is creating a legion of people who no longer need to fear getting sick, and are desperate to return to “normal” life. Yet the messaging on whether they might still carry and spread the disease—and thus whether it’s really safe for them to resume their unmasked, un-distanced lives—has been oblique. Anthony Fauci said last week on CNN that “it is conceivable, maybe likely,” that vaccinated people can get infected with the coronavirus and then spread it to someone else, and that more will be known about this likelihood “in some time, as we do some follow-up studies.” CDC Director Rochelle Walensky had been no more definitive on Meet the Press a few days before, where she told the host, “We don’t have a lot of data yet to inform exactly the question that you’re asking.”

When the polio vaccine was declared safe and effective, the news was met with jubilant celebration. Church bells rang across the nation, and factories blew their whistles. “Polio routed!” newspaper headlines exclaimed. “An historic victory,” “monumental,” “sensational,” newscasters declared. People erupted with joy across the United States. Some danced in the streets; others wept. Kids were sent home from school to celebrate.

One might have expected the initial approval of the coronavirus vaccines to spark similar jubilation—especially after a brutal pandemic year. But that didn’t happen. Instead, the steady drumbeat of good news about the vaccines has been met with a chorus of relentless pessimism.

At about 2 a.m. on Thursday morning, I woke to find my husband shivering beside me. For hours, he had been tossing in bed, exhausted but unable to sleep, nursing chills, a fever, and an agonizingly sore left arm. His teeth chattered. His forehead was freckled with sweat. And as I lay next to him, cinching blanket after blanket around his arms, I felt an immense sense of relief. All this misery was a sign that the immune cells in his body had been riled up by the second shot of a COVID-19 vaccine, and were well on their way to guarding him from future disease.

Side effects are a natural part of the vaccination process, as my colleague Sarah Zhang has written. Not everyone will experience them. But the two COVID-19 vaccines cleared for emergency use in the United States, made by Pfizer/BioNTech and Moderna, already have reputations for raising the hackles of the immune system: In both companies’ clinical trials, at least a third of the volunteers ended up with symptoms such as headaches and fatigue; fevers like my husband’s were less common.

We are living in a time of bad metaphors. Everything is fascism, or socialism; Hitler’s Germany, or Stalin’s Soviet Union. Republicans, especially, want their followers to believe that America is on the verge of a dramatic time, a moment of great conflict such as 1968—or perhaps, even worse, 1860. (The drama is the point, of course. No one ever says, “We’re living through 1955.”)

Ironically, the GOP is indeed replicating another political party in another time, but not as the heroes they imagine themselves to be. The Republican Party has become, in form if not in content, the Communist Party of the Soviet Union of the late 1970s.

I can already hear the howls about invidious comparisons. I do not mean that modern American Republicans are communists. Rather, I mean that the Republicans have entered their own kind of end-stage Bolshevism, as members of a party that is now exhausted by its failures, cynical about its own ideology, authoritarian by reflex, controlled as a personality cult by a failing old man, and looking for new adventures to rejuvenate its fortunes.

The world of Danish children’s television is not for the prudish. Kids who turn on the tube in Denmark might be greeted by gratuitous flatulence, cursing, casual nudity, or cross-dressing puppets. One show centers on a pipe-smoking pirate who wallops ninjas and flirts with Satanism. In another, an audience of 11-to-13-year-olds asks probing questions about the bodies of adults who disrobe before them. As Christian Groes, an anthropologist at Denmark’s Roskilde University, told me, Danish children’s television is not unlike an LSD trip: “Everything is possible in that universe,” he said, loosely quoting a friend, “and people won’t complain about it.”

But people did complain when the Danes debuted a kids’ animated series in January featuring a protagonist with an absurdly long, prehensile penis.

The past 11 months have been a crash course in a million concepts that you probably wish you knew a whole lot less about. Particle filtration. Ventilation. Epidemiological variables. And, perhaps above all else, interdependence. In forming quarantine bubbles, in donning protective gear just to buy groceries, in boiling our days down to only our most essential interactions, people around the world have been shown exactly how linked their lives and health are. Now, as COVID-19 vaccines rewrite the rules of pandemic life once more, we are due for a new lesson in how each person’s well-being is inextricably tangled with others’.

This odd (and hopefully brief) chapter in which some Americans are fully vaccinated, but not enough of us to shield the wider population against the coronavirus’s spread, brings with it a whole new set of practical and ethical questions. If I’m vaccinated, can I travel freely? Can two vaccinated people from different households eat lunch together? If your parents are vaccinated but you’re not, can you see them inside? What if only one of them got both shots? What if one of them is a nurse on a COVID-19 ward?

If you’re like me, you know that getting rid of your car is one of the best things you can do for the climate, and also that you will never do it. This is a car-oriented country, and a car-oriented time. But in 2019, the private cars and light trucks that ordinary people drive for work and shopping and leisure were responsible for about 15 percent of U.S. fossil-fuel-energy use. Electric vehicles get a lot of press, but less than 1 percent of energy used for transportation came from electricity. Personal transportation is a large contributor to carbon emissions in America; it’s also the hardest to give up.

But trading a gasoline automobile for an electric one (or for a bus or train) isn’t the only way ordinary citizens can contribute to fossil-fuel reduction. Decarbonization has two pillars: First, generate electricity from energy that does not emit carbon—renewable sources such as wind, solar, and geothermal instead of fossil fuels. That requires legislative and regulatory change. Second, use electricity to run as much of your personal life as possible.

On Tuesday evening, at the start of his Fox News show, Tucker Carlson shared the results of an investigation that he and his staff had conducted into a well-known agent of American disinformation. “We spent all day trying to locate the famous QAnon,” Carlson said, “which, in the end, we learned is not even a website. If it’s out there, we could not find it.” They kept looking, though, checking Marjorie Taylor Greene’s Twitter feed and “the intel community,” before coming to the obvious conclusion: “Cable news” and “politicians talking on TV,” Carlson said, must be responsible for the lies running rampant in America. “Maybe they’re from QAnon,” he added. “You be the judge.”

This anti-investigation, like so much of what happens on Carlson’s show every day, was funny right up until it was frightening. (Just before informing his viewers of his inability to locate QAnon.com, Carlson had attempted a rebranding of disinformation itself: “Freelance thinking,” he called it.) The most basic of good-faith searches would have revealed the reality—and the danger—of a widely believed conspiracy theory positing, in part, that Democrats eat children. But reality is not Carlson’s project. Destabilizing it is. Fox’s most popular personality, his show’s marketing literature will tell you, offers “spirited debates” about the news of the day. In truth, Carlson is simply selling cynicism. Night after night, he informs you that the ways you might have of understanding the world and yourself within it—politics, culture, science, art, the news, other people—are not to be trusted. The only American institution that remains worthy of your confidence, in the bleak cosmology of Tucker Carlson Tonight, is Tucker Carlson.
