Archaeologists find largest-ever Mayan complex hiding in plain sight
Researchers discover a massive ceremonial structure of the ancient Mayans using lasers.
- Archaeologists used laser-based aerial surveys to discover the oldest and largest Mayan structure ever found.
- The 3,000-year-old complex in the Mexican state of Tabasco was likely used as a ceremonial center.
- Researchers believe the site represents a communal society rather than one based on worshipping elites.
The southern tip of Mexico is hiding a giant Mayan structure from about 3,000 years ago, new research shows. The nearly one mile-long monument may be the oldest and largest ever found from the mysterious civilization. An accomplishment of this magnitude is making scientists rethink what they know about the knowledge of the ancient Mayans.
The site, known as Aguada Fénix, was discovered in the state of Tabasco, near the Gulf of Mexico. The complex, likely used as a ceremonial center and a place of gathering, was essentially hiding under the feet of modern-day Mexicans who live above the massive structure. It's 4,600 feet (1,400 meters) long and likely dates to between 1000 and 800 BCE. That time period, specifically, the year 950 BCE, also produced another Mayan site, known as Ceibal, which was previously considered the oldest-ever ceremonial center.
While potentially being even older, Aguada Fénix is also much larger and incomparable to anything else from that time, concluded the archaeologists led by University of Arizona professors Takeshi Inomata and Daniela Triadan.
"To our knowledge, this is the oldest monumental construction ever found in the Maya area and the largest in the entire pre-Hispanic history of the region," the researchers wrote in their study.
The research uncovered the secret of Aguada Fénix, which looks like a natural landscape above, via aerial surveys using the remote sensing method LIDAR. The analysis, which had laser beams sent from planes through the thick canopy of trees, showed an elevated platform that's almost a mile (1,413 meters) north to south, a quarter-mile (399 meters) east to west, and as much as 33 to 50 feet (15 meters) high. The platform also has nine wide causeways leading away from it, as well as small structures and artificial reservoirs around it.
"Artificial plateaus may be characterised as horizontal monumentality, which contrasts with the vertical dimensions of pyramids," explained the archaeologists. They connect the look of Aguada Fénix with what is known as the Middle Formative Usumacinta (MFU) pattern, distinct for its rectangular shape and rows of low mounds.
Another interesting find relates to the lack of statues shaped like humans in the ancient settlement. The scientists think this points to the fact that the society that lived there had no "clear indicators of marked social inequality, such as sculptures representing high-status individuals." In fact, the only stone sculpture they discovered in the area was of an animal.
This type of social organization, which was possibly less hierarchical and more communal, would be in great difference to other ancient people who inhabited the region like the Olmec from the nearby state of Veracruz. Their culture is known to have produced colossal stone heads.
"This kind of understanding gives us important implications about human capability, and the potential of human groups," Inomata shared, adding "You may not necessarily need a well-organised government to carry out these kinds of huge projects. People can work together to achieve amazing results."

The idea of 'absolute time' is an illusion. Physics and subjective experience reveal why.
- Since Einstein posited his theory of general relativity, we've understood that gravity has the power to warp space and time.
- This "time dilation" effect occurs even at small levels.
- Outside of physics, we experience distortions in how we perceive time — sometimes to a startling extent.
Physics without time<p>In his book "The Order of Time," Italian theoretical physicist Carlo Rovelli suggests that our perception of time — our sense that time is forever flowing forward — could be a highly subjective projection. After all, when you look at reality on the smallest scale (using equations of quantum gravity, at least), time vanishes.</p><p style="margin-left: 20px;">"If I observe the microscopic state of things," writes Rovelli, "then the difference between past and future vanishes … in the elementary grammar of things, there is no distinction between 'cause' and 'effect.'"</p><p>So, why do we perceive time as flowing <em>forward</em>? Rovelli notes that, although time disappears on extremely small scales, we still obviously perceive events occur sequentially in reality. In other words, we observe entropy: Order changing into disorder; an egg cracking and getting scrambled.</p><p>Rovelli says key aspects of time are described by the second law of thermodynamics, which states that heat always passes from hot to cold. This is a one-way street. For example, an ice cube melts into a hot cup of tea, never the reverse. Rovelli suggests a similar phenomenon might explain why we're only able to perceive the past and not the future.</p><p style="margin-left: 20px;">"Any time the future is definitely distinguishable from the past, there is something like heat involved," Rovelli wrote for the <a href="https://www.ft.com/content/ce6ef7b8-429a-11e8-93cf-67ac3a6482fd" target="_blank"><em>Financial Times</em></a>. "Thermodynamics traces the direction of time to something called the 'low entropy of the past', a still mysterious phenomenon on which discussions rage."</p>
The strange subjectivity of time<p>Time moves differently atop a mountain than it does on a beach. But you don't need to travel any distance at all to experience strange distortions in your perception of time. In moments of life-or-death fear, for example, your brain would release large amounts of adrenaline, which would speed up your internal clock, causing you to perceive the outside world as moving slowly.<br></p><p>Another common distortion occurs when we focus our attention in particular ways.</p><p style="margin-left: 20px;">"If you're thinking about how time is <em>currently</em> passing by, the biggest factor influencing your time perception is attention," Aaron Sackett, associate professor of marketing at the University of St. Thomas, told <em><a href="https://gizmodo.com/why-does-time-slow-down-and-speed-up-1840133782" target="_blank">Gizmodo</a></em>.<em> "</em>The more attention you give to the passage of time, the slower it tends to go. As you become distracted from time's passing—perhaps by something interesting happening nearby, or a good daydreaming session—you're more likely to lose track of time, giving you the feeling that it's slipping by more quickly than before. "Time flies when you're having fun," they say, but really, it's more like "time flies when you're thinking about other things." That's why time will also often fly by when you're definitely <em>not</em> having fun—like when you're having a heated argument or are terrified about an upcoming presentation."</p><p>One of the most mysterious ways people experience time-perception distortions is through psychedelic drugs. In an interview with <a href="https://www.theguardian.com/books/2018/apr/14/carlo-rovelli-exploding-commonsense-notions-order-of-time-interview" target="_blank"><em>The Guardian</em></a>, Rovelli described a time he experimented with LSD.</p><p style="margin-left: 20px;">"It was an extraordinarily strong experience that touched me also intellectually," he said. "Among the strange phenomena was the sense of time stopping. Things were happening in my mind but the clock was not going ahead; the flow of time was not passing any more. It was a total subversion of the structure of reality."<br></p><p>It seems few scientists or philosophers believe time is completely an illusion.</p><p style="margin-left: 20px;">"What we call <em>time</em> is a rich, stratified concept; it has many layers," Rovelli told <em><a href="https://physicstoday.scitation.org/do/10.1063/PT.6.4.20190219a/full/" target="_blank">Physics Today</a>.</em> "Some of time's layers apply only at limited scales within limited domains. This does not make them illusions."</p>What <em>is</em> an illusion is the idea that time flows at an absolute rate. The river of time might be flowing forever forward, but it moves at different speeds, between people, and even within your own mind.
