Astronomer Carl Sagan was a great science communicator, most widely known for the original "Cosmos" television series. He was also a prolific writer and in 1995 wrote the book "The Demon-Haunted World: Science as a Candle in the Dark" that touches on a variety of topics, from debunking hoaxes like alien abductions to spirituality, but ultimately serves as a passionate argument for science and the scientific method.
What's noteworthy is that a quote from the book has been picked up recently all over social media, based on its description of a future America that is eerily similar to its current state. While Sagan generally projected optimism, the quote talks about a possible dystopian society, with much division, confusion, mistrust of authority, a growing gap between the haves and have nots under an increasingly authoritarian leadership. Of course, you might quibble with some parts of this based on your politicial leanings, but there are even shades here of Trump's own dystopian Inauguration address.
Here's what the inimitable Carl Sagan wrote:
“Science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children's or grandchildren's time—when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what's true, we slide, almost without noticing, back into superstition and darkness."
Suspecting Carl Sagan had either a time machine or a crystal ball.

Notably, in the chapter that includes the quote, Carl Sagan continued talking about some American cultural debacles of that time (from his point of view) like the tv show "Beavis and Butthead" and the movie "Dumb and Dumber". He uses these as examples of the "dumbing down" of America. One can only wonder how he would update his take on America's future if he was alive today.

Here's Carl Sagan talking about the future of humanity in "Cosmos" (1980):
Meet ANITA. ANITA stands for "Antarctic Impulsive Transient Antenna." It seeks out cosmic rays from space as while hanging from a balloon suspended over Antarctica. In the last two years, though, it has twice detected cosmic rays coming from a direction no one expected: inside the earth. According to the Standard Model (SM) of physics, this shouldn't be possible.

And guess what? ANITA’s not alone
In September, a paper was submitted for peer review by astrophysicists at Penn State led by Derek Fox. "I was like, 'Well this model doesn't make much sense,'" Fox tells Live Science, "but the [ANITA] result is very intriguing, so I started checking up on it. I started talking to my office neighbor [and paper co-author] Steinn Sigurdsson about whether maybe we could gin up some more plausible explanations than the papers that have been published to date." Lacking any, they looked for other similar events and found three. They'd been detected by a surface-based Antarctic neutrino detector called, sensibly enough, IceCube. And when the data from ANITA and IceCube when combined, the Penn State scientists started getting excited. They calculate that whatever kind of particle is flying up and away from Earth has a less than 1-in-3.5 million chance of being any of the particles predicted by the Standard Model. Obviously, this has physicists scratching their heads trying to figure out what on earth is going on.

How cosmic rays are supposed to behave
First of all, of course, cosmic rays are supposed to come from out there somewhere, not here. The earth is bombarded with them all the time. The suspicion is that the newly detected particles are cosmic rays slamming into the earth on one side and somehow making it out the other.
Cosmic rays, though, are high-energy particles with relatively wide cross-sections that lead to their demise by causing them to crash into matter inside the Earth. They're "mainly (89%) protons — nuclei of hydrogen, the lightest and most common element in the universe — but they also include nuclei of helium (10%) and heavier nuclei (1%), all the way up to uranium particles," according to CERN. Low-energy neutrinos, on the other hand, can pass through the earth's rocky mass, but they're not involved with cosmic rays.
Both ANITA and IceCube track neutrinos indirectly by detecting their remains, if you will. They detect the particles neutrinos produce when they decay post-collision. Since neutrinos can't get through the earth, though, something else is producing these particles. But what?

They could be a new kind of particle…
One candidate put forward as responsible for the event is the elusive "sterile neutrino," first hinted at by evidence captured in the mid 1990s at the Liquid Scintillator Neutrino Detector (LSND) at Los Alamos. The data was interpreted as suggesting a weird kind of high-speed neutrino that simply passes through matter without any interaction. No one else was able to reproduce the result, and the idea fell out of favor. Until this last spring, that is, when MiniBooNE at Chicago's FermiLab captured new signs that it might exist. The sterile neutrino would break the Standard Model if confirmed, which is one of the things that make MiniBoonE's data exciting. "That would be huge," says Duke physicist Kate Scholberg, who wasn't involved with the research, "…that would require new particles ... and an all-new analytical framework."
Others have suggested that it could be a product of dark matter. Cool as either of these ideas would be, perhaps the strongest reason for the detected upward cosmic rays is even more thrilling.
…or they could be long-sought supersymetrical particles
According to the Standard Model, every particle has a symmetrical partner, but the particles we know about don't match up. To resolve this apparent imbalance, a class of thus-far-hidden "supersymmetrical" particles has been proposed. It was hoped that the Large Hadron Collider could detect these mysterious — and so far just theoretical — particles, but no. Since 2012, when the last known particle predicted the Standard Model, the Higgs-Boson, was detected, nothing new's been found.
Until, maybe, now.
What the Penn paper proposes
The Penn State paper suggests these South Pole upward cosmic rays could be our first sign of supersymmetricals, specifically the partner of the Standard Model's tau leptons. With a a couple of "S"es added to signify supersymmetry, they'd be stau sleptons.
Others agree that they could be the first actual evidence of supersymmetry. Los Alamos physicist Bill Louis tells LiveScience, "I think it's very compelling," though he adds that the pinpointing of a stau slepton is "a bit of a stretch."
Fox admits he certainly can't be sure, but that, "From my perspective, I go trawling around trying to discover new things about the universe, I come upon some really bizarre phenomenon, and then with my colleagues, we do a little literature search to see if anybody has ever thought that this might happen. And then if we find papers in the literature, including one from 14 years ago that predict something just like this phenomenon, then that gets really high weight from me." And, guess what, he did find a prediction from 2003 of stau sleptons showing up just like this.
An Armenian priest circles the Edicule, which marks the place where tradition holds Jesus was buried. The structure is located straight under the dome of the Church of the Holy Sepulchre in Jerusalem.
On a ledge over a church door in Jerusalem stands a simple cedarwood ladder. It's been there for perhaps three centuries. Since nobody remembers who put it there, nobody knows who is authorized to remove it. If anyone would try, there'd be immediate trouble with whomever would feel slighted — and there are plenty of candidates. This is the Immovable Ladder, and it is a fitting symbol for the deeply-entrenched divisions within Christianity, and within that church building itself.
The most sacred place on Earth
Those religious divides matter here more than anywhere else because this is the most significant church in the world. For Christians of any denomination this is the most sacred place on Earth. This is the Church of the Holy Sepulcher, and according to tradition, it contains both Golgotha (or Calvary in Latin; both mean "skull"), the place where Jesus died on the cross. Just a few feet further is the tomb (a.k.a. sepulcher) where his body was laid to rest and where according to the faithful he was resurrected three days later.
Yet despite its supreme religious importance, there is no single authority managing this holiest of church buildings. The care over the sprawling, multi-level complex is divided between various denominations.
The church's history goes back to the fourth century, when Roman emperor Constantine, newly converted to Christianity, sent his mother Helena to Jerusalem to locate places and things associated with the life and death of Jesus. This is the spot where she found the True Cross, a sign that this must have been Golgotha. The place of Jesus' burial was identified nearby. Constantine razed the pagan temple built here by his predecessor Hadrian, and a church on this spot, the first commissioned by a Roman emperor, was consecrated in the year 335.
In continuous use for 1700 years
The church has survived earthquakes, fires, invasions, and demolition by decree. It has been in continuous use for nearly 1700 years, even if the building standing there today is mostly a renovation and reconstruction dating to Crusader times. Over the centuries, various Christian traditions latched on to the church. Ownership became a constant source of dispute.
In 1852, the Ottoman Sultan decreed that the church was to be managed by the Greek Orthodox, Roman Catholic, and Armenian Apostolic churches and apportioned parts of the building to each denomination. Over time, smaller parts of the building came under the authority of three smaller Orthodox denominations: the Coptic, Syriac, and Ethiopian churches.
- Most of the building is under control of the Greek Orthodox church (in blue on the map). They manage the Katholikon (which is slightly ironic), the North Transept, the Seven Arches of the Virgin, a small Orthodox monastery, and various chapels, among other bits.
- The Latins (a.k.a. Roman Catholics, in purple) manage the Franciscan Monastery on the north side (which includes the Chapel of the Apparition and the Chapel of Mary Magdalene), the Grotto of the Invention of the Cross, a small area north of the Parvis, and a tiny space between the Katholikon and the Rotunda.
- The Armenians (in yellow) manage the Chapel of St. Helena, the Chapel of St. James, and the Armenian Gallery next to the Rotunda.
- The Copts (in red) have the care of various chapels near the Rotunda, including a small annex to the Edicule (i.e., the Holy Sepulcher) itself.
- The Ethiopian monastery is spread out on the roof, and the Ethiopians also manage an area called Deir al-Sultan, the Chapel of the Four Living Creatures, and the Chapel of St. Michael (all in orange).
- The Syriac church has the smallest part (in green): the Chapel of St. Nicodemus. But at least it's very close to the Sepulcher.
The Ottoman edict is the basis for the status quo, which is scrupulously maintained. A complex set of rules determines how the church is managed — such as who is allowed where and when, who cleans and repairs which parts of the building, and which areas are held in common (by the Greeks, Latins, and Armenians but not by the other three).
- The Rotunda is common territory, as is a chapel to the north.
- The Parvis (i.e. the courtyard at the entrance) is also common, as is an adjacent part of the church that contains the Stone of Unction (where according to tradition, Jesus' body was prepared for burial).
But some of the rules are disputed, and conflicts occasionally erupt. Two examples:
- The Copts have a long-standing claim over part of the roof, which is occupied by Ethiopian monks. To maintain their claim, Coptic monks take turns to sit on a chair on the roof. But on a particularly hot day in 2002, when a Coptic monk moved the chair a few inches into the shade, the Ethiopians interpreted that move as a violation of the status quo. The ensuing fight sent 11 monks to the hospital.
- And in 2008, Greek and Armenian monks got into a violent argument over the procedure of a religious procession. The brawl was caught on camera and pasted all over the news.
Can't we all just get along?
In recent years, however, the churches seem to be getting along a little bit better, although partly out of necessity. Significant parts of the building are in extreme need of repair. In 2017, the three main denominations (Catholic, Greek, and Armenian) agreed to fix the Edicule, which was in danger of collapsing. And in 2019, the three churches signed an agreement to renovate parts of the church's infrastructure (floor, foundations, and sewage pipes) and even to share ownership of any archaeological artifacts that might turn up during the work. However, the agreement excludes the three other denominations, which under the status quo have no say in the management of shared spaces.
Which brings us back to the Immovable Ladder. Despite its nickname, it has proven to be very movable indeed. It was stolen twice in the 20th century. Both times, it was soon recovered by the police and returned to its original position. In 2009, it was moved again, this time with the agreement of all relevant denominations, in order to accommodate scaffolding for renovations.
Upon completion of the works, it was again put back. And there it will remain until, as Pope Paul VI suggested in 1964, the divisions between the various Christian denominations are resolved. Or until Christ returns — whichever happens first.
Meanwhile, the keys to the church building itself will remain where they have been for centuries: in the possession of the Joudeh and Nuseibeh families, who by virtue of their Muslim faith are accepted by all Christian denominations as neutral guardians of the entrance to the church.
