Feeling anxious last night from the drumbeat of COVID-19 news, so I took a quick drive to the park at Lake Jackson to shoot some night photos. These were shot on my Pixel and I think they’re pretty darned good for a phone.
Took a nice long walk with the dog in a local park this afternoon. This is my first camera roll post in a long time. The last few months have been crazy!
These have been sitting around since a rainy day back in July. I had my trusty Nikon Lite-Touch Zoom 120 with a roll of Ilford HP5 as we dodged summer showers from shop to shop in Railroad Square here in Tallahassee.
There’s a problem with the universe.
Some people here in my hometown feel that way because the Seminoles are losing football games, but I’m talking about the real universe, the one out there. Right now, scientists who study the universe are puzzling over the answer to a simple equation,
Ho=v/d. This equation has been with us since 1929, when Edwin Hubble discovered that all galaxies, in all directions, appear to be moving away from us here on earth. If you plug in a couple of measurements, he found–the velocity at which one of these galaxies is moving away from the Earth, v, and the retreating galaxy’s distance from the earth, d–you should come up with a simple number. This number describes the universe’s rate of expansion, and it’s called the Hubble Constant in honor of its inventor.
The Hubble Constant is important because it lies at the heart of how we understand the history of the universe. Using this measurement, physicists have inferred that the universe has progressed through three eras of expansion. First, they argue, it expanded very rapidly. This was the time around the Big Bang, billions of years ago, when the universe exploded into existence. Over time, the gravitational pull of a strange substance called dark matter slowed this initial expansion, but in the current era, a strange force called dark energy is speeding the expansion again. As you might guess, this model only works if the Constant is actually constant. For something that’s supposed to be a constant, however, the Hubble Constant has changed an awful lot.
When Hubble plugged in his numbers in 1929, for example, he came up with a number around 500 km/s/Mpc. That is around 99.4 miles per second per million-light-years, I think, but scientists were never happy with that number anyway. It took a long time for the physicists to reach consensus, in fact, but rival camps of researchers by the 1970s had at least settled into a pattern, with measurements of the “constant” ranging between 55 and 100 km/s/Mpc. Not only was the Hubble Constant unconstant, it was also controversial. When a group of physicists tried to solve the problem once and for all at a conference in Aspen in 1985, one of the participants says, “there really was no way to get the old timers to work with the young turks.” The controversy would continue.
Thirteen of the Aspen group realized that the problem was really about calibrating instruments to come up with a good measurement. When you try to observe something with precision from billions of miles away, it turns out, there are a lot of things that can go wrong. I understand this. I tried to take pictures of the moon with my smartphone mounted to a telescope just last month and ended the night with two blurry photos and a bad mood. Even with the best equipment in the world and a PhD in astrophysics, trying to measure the radial velocity of a distant galaxy is really hard.
Enter the Hubble Space Telescope. If you were alive in the 1990s, you probably heard about the Hubble on the news or read about it in the newspaper, because it was originally launched with a flaw in its enormous mirror and had to be fixed by spacewalking astronauts in 1993. Once the extremely expensive mirror was fixed, the orbiting telescope completely changed the field of astronomy. Solving the Hubble Constant dilemma was one of its goals and, with fresh new glass, it worked. By the late nineties, scientists using the Hubble reduced variability in measurements of the Constant to less than 10%. With the Hubble data, finally, scientists could tell us how quickly the universe was expanding and, therefore, how old it is. Cue the celebration.
This celebration is coming to a halt. Over the past few years, physicists have been looking at new areas, using different tools and methods, and coming up with different values for the Constant based on where they look. After measuring the light from exploding stars, one group argues that the value is 73. Two other groups argue that the number is 67, based on measurements of cosmic radiation, or 70, based on analysis of the light from red giant stars. Last month, another group of physicists published a paper using gravitational lenses to argue that the value is actually 77. That nice model of the universe, with rapid expansion, slowing, and speeding back up? It doesn’t work if the Hubble Constant is different in different places. Physicists are struggling now to come up with a new explanation for how the universe works.
Tell me if this sounds familiar. Some time after World War II, everyone agreed on a norm. In this case, it was a Hubble Constant somewhere between 50 and 100; but you can imagine if you like that the norm might be something like, Presidents release their tax returns. Everyone used that norm to build a really strong and comfortable system. In this case, that system was the standard model of cosmology; but you can imagine, again, that it might be something like, postwar American prosperity. Then, new tools gave everyone a lot more information, and the norm started to break down. People started putting that information together in new ways, and, for them, the norm–the Constant–should be 73, or 67, or 77.The evidence supports their claims. It’s all just a matter of where they choose to look and what they choose to measure.
This reminds me of Willie Taggart, the unfortunate head football coach at Florida State University. Some of the facts about Coach Taggart are hard to dispute. Taggart was hired in late 2017, after the ignominious departure of the last coach, Jimbo Fisher. Taggart inherited a football team that was in trouble. Fisher had not recruited well in his last season. Many of the team’s most talented players had graduated in the two years before. Taggart promised success through simplicity nonetheless. He achieved a record of just 9 wins and 12 losses before he was fired by the university on November 3, 2019.
This is where we are right now: awash in so much information, so many points of view, so much evidence, that just about everything can be argued cohesively. While Taggart was here in Tallahassee–I assume that he’s gone now, just to get away from the smoldering indignity of it all–I read and heard and made so many arguments about the coach that I can’t remember them all. I heard he’s getting better, just look at the NC State game, and I thought: sure, yeah, that makes sense. But then I read, he’s not getting any better, just look at all of the penalties, and I thought, too: well, shucks, that also makes sense. I scrolled over similarly conflicting opinions on my twitter and facebook feed every Saturday, sparred over inconsistent and opposite viewpoints with friends on Monday, and most of the arguments on either side made sense.
It could be that I’m just a bad reader of football opinion, but I’m not alone. The whole city this autumn was wracked by two poles of opinion. One: you can’t fire a coach until he’s had at least three seasons to turn things around. Two: if the team’s not getting better they need to move on now. These tribal pole stars were like Hubble Constants of 67 and 77. Both were plausible and well-supported by people who knew what they were talking about, and both were true if you accepted the evidence. They were also complete opposites.
This is where football starts to diverge from the Hubble analogy. Conflicting information in science leads to new science, but conflicting information in culture leads to politics. “Any time there’s a discrepancy, some kind of anomaly,” physicist Katherine Mack told the Washington Post for a story about the Constant, “we all get very excited.” I don’t think anyone is excited about politics anymore. Unfortunately, the politics of the Taggart situation are unavoidable. Like pretty much everything else in America, Taggart’s story boils down to the bone stock of the culture war: race and class.
The internet is made up of little building blocks of information. Like Legos, you can take this information apart and put it back together into just about anything you want. While there are more communities on the web than any of us can imagine, it seems like most people in these communities use politics to help them understand how they should put information together. College football communities are no different. Ever since Taggart arrived in Tallahassee, the culture warriors who care about FSU football started taking information about his tenure apart and putting it together in shapes that fit their worldview. By the end of his first season, an upset fan posted a lynching meme over the caption, “Believe in something. Even if it means sacrificing your rep.” The university condemned the post and everyone moved on, but the subtext was now out in the open. The stakes for Taggart were higher, and the obstacles more formidable, than they would have been for a white coach.
Ask any of Coach Taggart’s detractors, and they’ll tell you: they’re not racists. But, racists or not, race was such an important part of the Taggart story that we can’t ignore it. Earlier this year I found myself in the middle of an extremely minor Twitter skirmish between Taggart supporters and Taggart detractors arguing over a stunt involving a lemonade stand and a prominent Booster. The Booster told me the whole thing was a joke and saw himself out of the conversation, but critics and supporters kept coming in for a little while longer. It was hard to generalize about the coach’s supporters, but his critics were easier to pin down. Sunglasses, always. An exhausting barrage of exclamation points. Somewhere the phrase, “I support THE PRESIDENT.” Even a rebel flag. Some of the accounts have been deleted since then, for some later infraction or indecency. A true badge of honor.
The Taggart saga was only a minor flash point in the broader culture war consuming all of us, but viewing it through that lens makes it easier to understand how it could take over a town. Provocative critics pushed their arguments to the very edge of acceptability and, at least once, well beyond. The rest of us could only fume, could only point angry fingers at racism indirectly, like trying to look at a dim star you can only see when you look away. These provocateurs used football to talk about race. When they pulled it off just right, they could push a little further. When they failed, they could scurry behind a screen of deniability. It was all a joke. Chill out. It’s only football. Perhaps the rest of us, to be fair, are using race to talk about football. It’s deadly serious. Wake up. It’s more than a game. Either way, there’s so much information out there that we can choose which Lego set we want to play with. Nobody is happy with this state of affairs.
In the 1960s, a philosopher named Thomas Kuhn argued that scientific knowledge doesn’t grow in a straight line, steadily advancing as scientists dream up new experiments to test new hypotheses. Instead, Kuhn argued, science progresses through occasional, groundbreaking paradigm shifts, followed by long periods of “normal” work to test the paradigm. Kuhn’s argument was a breakthrough in 1962–a paradigm shift in its own right–that has come under fire, like pretty much all ideas, in the six decades since then; but much of it still rings true. Especially this, especially now: all of that “normal” work in science eventually introduces so much chaos to the theory, so many unanswered questions, that only a whole new theory can clear the board. This is why physicists are excited by the Hubble Constant tension. They can see new science just over the horizon. If we use football as a looking-glass on society, should we be excited too? Is there a new politics just over the horizon? Coach Taggart’s brief experience in the capital city suggests not. We’re long overdue for a paradigm shift.
Out exploring the logic of dispossession on the “Seminole Wars Heritage Trail.” Stop #1: Miccosukee Village. Taking notes toward a book.
Only a historic marker remains to remind people of the thriving Native community that once drew a living from the fields, forests, and lakes northeast of the Tallahassee old fields. State Road 59 leading to the memorial cuts a meandering line between fabricated plantation gentility on one side and desperate poverty on the other, but it’s easy to see what the settlers saw in this land, nevertheless, as you pass beneath the spreading oak and pine boughs and smell the first hints of autumn pass through your open car windows.
A quick, Labor Day afternoon stroll. Is it finally cooling off?
The Grove is a historic house that has been converted into a museum in midtown Tallahassee. It stands, behind a screen of stately oaks, next to a busy intersection amid attorney’s offices, stores, and restaurants. The mercury was hovering around 100° F when I visited recently, and the traffic on Monroe Street nearby was raging, but the Grove was like an oasis of shaded calm. The staff offer tours of the home at the top of every hour, and visitors are free to walk the grounds and soak up some peace before heading back out into the busy capital city. Check out the Governor’s Mansion next door if you have a few minutes to gawk. Though the Governor’s Mansion is not open to the general public, it is possible to schedule a tour during the legislative session.
