Minerals taken from lagoons reveal a century-long drought occurred between A.D. 800 and A.D. 900, right when the Mayan civilization disintegrated. |
Minerals taken from Belize's famous underwater cave, known as the Blue Hole, as well as lagoons nearby, show that an extreme, century-long drought occurred between A.D. 800 and A.D. 900, right when the Mayan civilization disintegrated. After the rains returned, the Mayans moved north — but they disappeared again a few centuries later, and that disappearance occurred at the same time as another dry spell, the sediments reveal.
Rise and decline
From A.D. 300 to A.D. 700, the Mayan civilization flourished in the Yucatan peninsula. These ancient Mesoamericans built stunning pyramids, mastered astronomy, and developed both a hieroglyphic writing system and a calendar system, which is famous for allegedly predicting that the world would end in 2012.
But in the centuries after A.D. 700, the civilization's building activities slowed and the culture descended into warfare and anarchy. Historians have speculatively linked that decline with everything from the ancient society's fear of malevolent spirits to deforestation completed to make way for cropland to the loss of favored foods, such as the Tikal deer.
The evidence for a drought has been growing in recent years: Since at least 1995, scientists have been looking more closely at the effects of drought. A 2012 study in the journal Science analyzed a 2,000-year-old stalagmite from a cave in southern Belize and found that sharp decreases in rainfall coincided with periods of decline in the culture. But that data came from just one cave, which meant it was difficult to make predictions for the area as a whole, Droxler said.
The main driver of this drought is thought to have been a shift in the intertropical convergence zone (ITCZ), a weather system that generally dumps water on tropical regions of the world while drying out the subtropics. During summers, the ITCZ pelts the Yucatan peninsula with rain, but the system travels farther south in the winter. Many scientists have suggested that during the Mayan decline, this monsoon system may have missed the Yucatan peninsula altogether.
Deep history
The team found that during the period between A.D. 800 and A.D. 1000, when the Mayan civilization collapsed, there were just one or two tropical cyclones every two decades, as opposed to the usual five or six. After that, the Maya moved north, building at sites such as Chichen Itza, in what is now Mexico.
But the new results also found that between A.D. 1000 and A.D. 1100, during the height of the Little Ice Age, another major drought struck. This period coincides with the fall of Chichen Itza.
The findings strengthen the case that drought helped usher in the long decline of the Mayan culture.

Decades after that first small step, space thinkers are finally getting serious about our nearest neighbor By Kevin Hartnett
This week, the European Space Agency made headlines with the first successful landing of a spacecraft on a comet, 317 million miles from Earth. It was an upbeat moment after two American crashes: the unmanned private rocket that exploded on its way to resupply the International Space Station, and the Virgin Galactic spaceplane that crashed in the Mojave Desert, killing a pilot and raising questions about whether individual businesses are up to the task of operating in space. During this same period, there was one other piece of space news, one far less widely reported in the United States: On Nov. 1, China successfully returned a moon probe to Earth. That mission follows China’s landing of the Yutu moon rover late last year, and its announcement that it will conduct a sample-return mission to the moon in 2017. With NASA and the Europeans focused on robot exploration of distant targets, a moon landing might not seem like a big deal: We’ve been there, and other countries are just catching up. But in recent years, interest in the moon has begun to percolate again, both in the United States and abroad—and it’s catalyzing a surprisingly diverse set of plans for how our nearby satellite will contribute to our space future. China, India, and Japan have all completed lunar missions in the last decade, and have more in mind. Both China and Japan want to build unmanned bases in the early part of the next decade as a prelude to returning a human to the moon. In the United States, meanwhile, entrepreneurs are hatching plans for lunar commerce; one company even promises to ferry freight for paying customers to the moon as early as next year. Scientists are hatching more far-out ideas to mine hydrogen from the poles and build colonies deep in sky-lit lunar caves. This rush of activity has been spurred in part by the Google Lunar X Prize, a $20 million award, expiring in 2015, for the first private team to land a working rover on the moon and prove it by sending back video. It is also driven by a certain understanding: If we really want to launch expeditions deeper into space, our first goal should be to travel safely to the moon—and maybe even figure out how to live there.
Entrepreneurial visions of opening the moon to commerce can seem fanciful, especially in light of the Virgin Galactic and Orbital Sciences crashes, which remind us how far we are from having a truly functional space economy. They also face an uncertain legal environment—in a sense, space belongs to everyone and to no one—whose boundaries will be tested as soon as missions start to succeed. Still, as these plans take shape, they’re a reminder that leaping blindly is sometimes a necessary step in opening any new frontier.
“All I can say is if lunar commerce is foolish,” said Columbia University astrophysicist Arlin Crotts in an e-mail, “there are a lot of industrious and dedicated fools out there!”
At its height, the Apollo program accounted for more than 4 percent of the federal budget. Today, with a mothballed shuttle and a downscaled space station, it can seem almost imaginary that humans actually walked on the moon and came back—and that we did it in the age of adding machines and rotary phones.
“In five years, we jumped into the middle of the 21st century,” says Roger Handberg, a political scientist who studies space policy at the University of Central Florida, speaking of the Apollo program. “No one thought that 40 years later we’d be in a situation where the International Space Station is the height of our ambition.”

An image of Earth and the moon created from photos by Mariner 10, launched in 1973.Without a clear goal and a geopolitical rivalry to drive it, the space program had to compete with a lot of other national priorities. The dramatic moon shot became an outlier in the longer, slower story of building scientific achievements.
Now, as those achievements accumulate, the moon is coming back into the picture. For a variety of reasons, it’s pretty much guaranteed to play a central role in any meaningful excursions we take into space. It’s the nearest planetary body to our own—238,900 miles away, which the Apollo voyages covered in three days. It has low gravity, which makes it relatively easy to get onto and off of the lunar surface, and it has no atmosphere, which allows telescopes a clearer view into deep space.
The moon itself also still holds some scientific mysteries. A 2007 report on the future of lunar exploration from the National Academies called the moon a place of “profound scientific value,” pointing out that it’s a unique place to study how planets formed, including ours. The surface of the moon is incredibly stable—no tectonic plates, no active volcanoes, no wind, no rain—which means that the loose rock, or regolith, on the moon’s surface looks the way the surface of the earth might have looked billions of years ago.
NASA still launches regular orbital missions to the moon, but its focus is on more distant points. (In a 2010 speech, President Obama brushed off the moon, saying, “We’ve been there before.”) For emerging space powers, though, the moon is still the trophy destination that it was for the United States and the Soviet Union in the 1960s. In 2008 an Indian probe relayed the best evidence yet that there’s water on the moon, locked in ice deep in craters at the lunar poles. China landed a rover on the surface of the moon in December 2013, though it soon malfunctioned. Despite that setback, China plans a sample-return mission in 2017, which would be the first since a Soviet capsule brought back 6 ounces of lunar soil in 1976.
The moon has also drawn the attention of space-minded entrepreneurs. One of the most obvious opportunities is to deliver scientific instruments for government agencies and universities. This is an attractive, ready clientele in theory, explains Paul Spudis, a scientist at the Lunar and Planetary Institute in Houston, though there’s a hitch: “The basic problem with that as a market,” he says, “is scientists never have money of their own.”
One company aspiring to the delivery role is Astrobotic, a startup of young Carnegie Mellon engineers based in Pittsburgh, which is currently positioning itself to be “FedEx to the moon,” says John Thornton, the company’s CEO. Astrobotic has signed a contract with SpaceX, the commercial space firm founded by Elon Musk, to use a Falcon 9 for an inaugural delivery trip in 2015, just in time to claim the Google Lunar X Prize. Thornton says most of the technology is in place for the mission, and that the biggest remaining hurdle is figuring out how to engineer a soft, automated moon landing.
Astrobotic is charging $1.2 million per kilogram—you can, in fact, place an order on its website—and Thornton says the company has five customers so far. They include the entities you might expect, like NASA, but also less obvious ones, like a company that wants to deliver human ashes for permanent internment and a Japanese soft drink manufacturer that wants to place its signature beverage, Pocari Sweat, on the moon as a publicity stunt. Astrobotic is joined in this small sci-fi economy by Moon Express out of Mountain View, Calif., another company competing for the Google Lunar X Prize.
Plans like these are the low-hanging fruit of the lunar economy, the easiest ideas to imagine and execute. Longer-scale thinkers are envisioning ways that the moon will play a larger role in human affairs—and that, says Crotts, is where “serious resource exploitation” comes in.
If this triggers fears of a mined-out moon, be reassured: “Apollo went there and found nothing we wanted. Had we found anything we really wanted, we would have gone back and there would have been a new gold rush,” says Roger Launius, the former chief historian of NASA and now a curator at the National Air and Space Museum.
There is one possible exception: helium-3, an isotope used in nuclear fusion research. It is rare on Earth but thought to be abundant on the surface of the moon, which could make the moon an important energy source if we ever figure out how to harness fusion energy. More immediately intriguing is the billion tons of water ice the scientific community increasingly believes is stored at the poles. If it’s there, that opens the possibility of sustained lunar settlement—the water could be consumed as a liquid, or split into oxygen for breathing and hydrogen for fuel.
The presence of water could also open a potentially ripe market providing services to the multibillion dollar geosynchronous satellite industry. “We lose billions of dollars a year of geosynchronous satellites because they drift out of orbit,” says Crotts. In a new book, “The New Moon: Water, Exploration, and Future Habitation,” he outlines plans for what he calls a “cislunar tug”: a space tugboat of sorts that would commute between the moon and orbiting satellites, resupplying them with propellant, derived from the hydrogen in water, and nudging them back into the correct orbital position.
In the long term, the truly irreplaceable value of the moon may lie elsewhere, as a staging area for expeditions deeper into space. The most expensive and dangerous part of space travel is lifting cargo out of and back into the Earth’s atmosphere, and some people imagine cutting out those steps by establishing a permanent base on the moon. In this scenario, we’d build lunar colonies deep in natural caves in order to escape the micrometeorites and toxic doses of solar radiation that bombard the moon, all the while preparing for trips to more distant points.
gical hurdles is long, and there’s also a legal one, at least where commerce is concerned. The moon falls under the purview of the Outer Space Treaty, which the United States signed in 1967, and which prohibits countries from claiming any territory on the moon—or anywhere else in space—as their own.
“It is totally unclear whether a private sector entity can extract resources from the moon and gain title or property rights to it,” says Joanne Gabrynowicz, an expert on space law and currently a visiting professor at Beijing Institute of Technology School of Law. She adds that a later document, the 1979 Moon Treaty, which the United States has not signed, anticipates mining on the moon, but leaves open the question of how property rights would be determined.
There are lots of reasons the moon may never realize its potential to mint the world’s first trillionaires, as some space enthusiasts have predicted. But to the most dedicated space entrepreneurs, the economic and legal arguments reflect short-sighted thinking. They point out that when European explorers set sail in the 15th and 16th centuries, they assumed they’d find a fortune in gold waiting for them on the other side of the Atlantic. The real prizes ended up being very different—and slow to materialize.
“When we settled the New World, we didn’t bring a whole lot back to Europe [at first],” Thornton says. “You have to create infrastructure to enable that kind of transfer of goods.” He believes that in the case of the moon, we’ll figure out how to do that eventually.
Roger Handberg is as clear-eyed as anyone about the reasons why the moon may never become more than an object of wonder, but he also understands why we can’t turn away from it completely. That challenge, in the end, may finally be what lures us back.

People save up for retirement, but how well do we prepare for the journey after? Ancient cultures put great emphasis on the afterlife, because they knew consciousness continued after death. They were right: Out-of-body experiences reveal we really do exist beyond the body. Knowing this truth should inspire us to seek in life what really matters and remains after death – awakened consciousness.
What is the greatest mystery of life? According to a legendary Q&A in the Indian spiritual epic the Mahabharata, the greatest wonder is that countless people die every day, yet those left behind believe they will live forever.
There is a well-known saying that the only certainty in life is death, but our hyper-connected modern society is not exactly inspiring much reflection on what lies beyond the transient.
People put aside savings for retirement, and some take out life insurance to take care of the loved ones they leave behind. This looks after physical needs, but what about the needs of consciousness which continues without the body? What preparations are made for its journey after death – the ultimate journey of a lifetime?
Religious institutions offer a solution to their followers that usually depends on adopting a set of beliefs rather than personal spiritual discovery. On the other hand, some scientists will tell you with equal conviction that nothing comes after death, so don’t worry about it. Both of these points of view depend on belief, but what if, when the final moment comes, you realise you wasted the great opportunity your life provided? An alternative option is to discover for ourselves why we are here, and what our place in the universe is, while we are alive and have the opportunity to do something with the knowledge we gain.
Ancient spiritual cultures almost universally placed importance on the individual’s preparations and journey into the afterlife. They clearly understood our existence extended beyond our bodies, and that life and death were best seen with the bigger picture of creation in mind – as part of an ongoing journey of consciousness – with life presenting an amazing opportunity for conscious evolution that we take the fruits from after death.
This was bought home to me in an interesting way during a trip to a museum exhibition showcasing ancient Egyptian afterlife cosmology; it reminded me of the universal nature of the afterlife, and how Near-Death Experiences and Out-of-Body Experiences offer us a glimpse into the reality of existence beyond the body, revealing that awakening consciousness is what creation is really all about.
With our modern culture drifting more and more into shallow short-sighted materialism and faux metaphysics, the need to re-discover and live this deeper purpose to life, so cherished by the ancients, is more important than ever.
A Journey into the Ancient Egyptian Afterlife
A while back I was fortunate to have the opportunity to take a one-way self-guided tour through the ancient Egyptian afterlife, thanks to a special museum exhibition featuring artefacts from the British Museum collection.
The local museum was packed, and we had to wait in a queue before being allowed in. Finally we entered a dimly-lit passage thronging with people, winding past ancient Egyptian artefacts, artworks, tools, scriptures, and mummies.
The exhibit started with depictions of ancient Egyptian cosmology like this. Here the sky goddess is held up above the earth.There were ancient scrolls of the pyramid texts on display, and ancient art depicting the soul’s journey through the afterlife. A major theme in their art was judgement and the “weighing of the heart”, where a deceased person’s heart was weighed against a feather, and their fate was dependent on their inner qualities and the sum of their actions while alive. Toward the end of the exhibition they had a mockup display of this, with a large set of scales on which you could weigh your “heart” against a feather, while Egyptian Gods looked on from a mural.
After that, you passed into a depiction of the Egyptian paradise before stepping outside into the sunlight. I doubt the effect was intentional on the part of the exhibitors, but after passing through the exhibition’s dark passageway with its ordered depictions of the afterlife, judgment and then stepping into the light, I couldn’t help but think of accounts of near-death experiences, in which people often report passing through a dark tunnel toward the light, and experiencing a life review where they see the consequences of all their actions.
Depiction of the “weighing of the heart”From looking at artefacts from different periods, it was apparent the ancient Egyptian understanding of death changed over time. It seemed to me that originally, the emphasis was on living spiritually and obtaining an immortality of the soul, while in later periods their understanding declined into more literal interpretations of preparing the body (rather than consciousness) for the afterlife through mummification, and a preoccupation with the arrangement of one’s burial and tomb with the right spells and amulets.
But I was vividly struck by how through that civilisation’s long and varied existence, the importance of the afterlife always reigned supreme, and being prepared for life after death was absolutely central to existence. Death, and therefore life, was taken very seriously.
I couldn’t help but notice a stark contrast between our modern culture and theirs. It was a bit like being in some kind of time warp, where two very different cultures collided. The artefacts of the Egyptians gave a sense of the sacredness of life and creation, but the bustling, noisy crowds of modern onlookers apparently saw this ancient preoccupation with the afterlife as mere novelty and amusement. How different ancient Egypt was to our modern society where the reality, and inevitability, of death is given little thought or preparation, and the understanding that consciousness continues after death is often summarily discounted and ridiculed.
I highly doubt that many people who attended the exhibition paused to reflect on whether they would continue to exist after death and, if so, how? And why are we here anyway? This was driven home when, just prior to reaching the scales of “judgement”, I noticed a whiteboard, styled with papyrus veneer, with a pertinent question written at the top.
What would you take with you to the afterlife?
Good question. A pen hung from the board, inviting people to write their response underneath. The answers ranged from the sentimental, to the mundane, to the silly.
How would you answer the question?A “time machine” was perhaps the only clever response. I could see the benefit of that if you realised you had wasted your life. I don’t think it’s really an option however.
This brought home how we don’t take death and the meaning of our lives anywhere near as seriously as we should today. The ancients knew a lot more about life and death than we do. We have lost their ancient wisdom, and with it the understanding of the amazing opportunity our existence in this universe presents.
This is a serious problem. Our consciousness will continue to exist without the body. But if we don’t question our existence and why we are here, we will not awaken consciousness and we will never reach our true potential.
Near-Death Experiences and the Reality of Existence Beyond the Body
Existence after death is not something the ancient Egyptians invented. Concepts of an afterlife are so common across geographically isolated cultures around the world that it cannot simply be dismissed as a coincidence. There may be cultural differences in the details, but the understanding that we continue existing without the body has been pretty much universal for thousands of years.
In fact, the burial of the dead and the realisation of an afterlife are considered some of the most important hallmarks of cultural development in Stone Age people. It was a sign of intelligence distinguishing people from animals, and paved the way for the development of more sophisticated civilisations.
The medieval painting ‘Ascent of the Blessed’ by Hieronymus Bosch shows the light at the end of the tunnel common to NDE accountsThese include an out of body experience, where they leave their body and realise they are separate from it, perhaps seeing their body lying beneath them. Then they may go on a journey, which may feature common aspects like travelling through a tunnel, and a life review, where a person is shown everything they have done, and feels the effects of their actions toward others, whether good or bad.
Although some scientists speculate that these phenomena may be caused by the brain, the reality is that these experiences have occurred when patients are clinically brain dead, and it has not been proven these experiences are produced biologically. Furthermore, there is no ultimate proof that consciousness is produced by the brain anyway, although this is a strongly-held assumption among those entrenched in materialistic beliefs.
NDEs challenge rigid materialistic beliefs about life. In light of the prevalence and commonality of NDEs, some scientists now suggest that consciousness interacts with the brain rather than being produced by it. Rather, the brain is a conduit through which consciousness can express itself, much like the way a computer is a conduit for the internet, but the internet continues to exist when the computer is switched off.
NDEs are increasingly reported in the modern world due to improvements in health care leading to more people being revived, but they are also an ancient phenomenon. Research by the scholar Gregory Shushan found there are universal afterlife experiences which underpinned both modern NDE accounts and ancient afterlife mythologies. His research involved an in-depth comparative analysis of afterlife conceptions of five ancient civilisations (Old and Middle Kingdom Egypt, Sumerian and Old Babylonian Mesopotamia, Vedic India, pre-Buddhist China, and pre-Columbian Mesoamerica) and compared them to modern NDE accounts. He demonstrated that, although there were some variations in the details based on the cultural origin, there were specific recurring similarities that reappeared too consistently to be mere coincidence, suggesting that, “afterlife conceptions are not entirely culturally-determined and… appear to be universal or quasi-universal to some degree”.
Life is an Opportunity to Awaken Consciousness
Realising that you are consciousness, and continue to exist without the body, awakens you to the bigger picture of life. It puts your whole life in perspective.
In an NDE life review, people tend to see that what really matters in life is not how much money they made or what they achieved in a given field, but how they treated other people, and whether they acted with love. These experiences tend to change people’s lives, inspiring them to be more spiritual.
Realising that we exist beyond the body can open the door to awakening. You realise that what really matters in life is not what we gain physically, but developing consciousness. Then the question, “what will you take with you to the afterlife” becomes much more meaningful. You can’t take physical things with you when you die like your iPhone, but you can take consciousness. Then you see that the focus on the afterlife in ancient cultures was not a preoccupation with death, but a deep understanding of life, and how to live it in the most meaningful way to bring spiritual benefits to yourself and others, the effects of which continue after death.
States like anger, greed and hatred have their consequences in the world which are bad enough, but who wants to take these states with them to afterlife? If these states don’t bring happiness here, why drag them along after death? Expressions of consciousness like love, wisdom and inner peace are much better qualities to carry within. By awakening and expressing consciousness in a world filled with ignorance, hatred and darkness, we not only help to make the world a better place, but continue to carry these spiritual qualities in our consciousness when our body is left behind.
Understanding this is so important today. We live in a society bombarded with elite-controlled propaganda and entertainment that not only hides the darker agendas working in the world, but blankets people in ignorance, keeping us from uncovering the deeper potential of our consciousness and empowering ourselves by striving to awaken – which enables us to break free of the grip of darkness that exerts its influence over humanity. Failing to wake up to this agenda has it implications in the world, and also for our consciousness, and it’s consciousness that really counts, both in life and beyond.
So what would you take with you to the afterlife?
