The Same Way We Dig Up Dinosaur Bones, Future Explorers Will Dig Up Fossilized Machines

If some kind of apocalypse knocks us back to the Stone Age and we recover enough to start digging up fossils again, then future archaeology is going to be really weird. On a long enough timescale, anything can be swallowed by the Earth and fossilized until we dig it up and stick it in a museum. That includes whatever you're using to read this article right now.

According to scientists writing for The Anthropocene Review, everything that we manufacture, from pens to garage doors to tractors, will eventually be covered up by sand and dirt and become "technofossils." That sounds like a bullshit term made up for a Michael Bay movie, but it's a real concept which kids might learn in third grade one day.

Imagine future dig sites where people are using little chisels and brushes to delicately extract your PlayStation, or your phone charger, or your dildo (or your phone charger / dildo). And depending on how far removed our cultural memory is from modern times, they'll probably have no idea what half of this stuff even is. Future museums might look like Ariel's treasure room from The Little Mermaid, with plaques explaining how forks were used for combing hair and cheese graters were defensive weapons.

If Humans Ever Forget What Satellites Are, Future Astronomers Will Be Screwed

Ever wondered what would happen to the over 1,000 active satellites orbiting the Earth right now if we suddenly lost the ability to maintain them? Like maybe there's a nuclear apocalypse, or someone forgets the password. Well, most of them would fall back to Earth within 25 years, while others (the larger ones that run the risk of surviving reentry and smacking some poor SOB in the face) are blasted further out into a 500-year orbit at the end of their lives. The latter would be our great-great-great-great-grandchildren's problem, but not ours.

But then there are the "geosynchronous" satellites -- the ones which are designed to exactly match the rotation of the Earth. To us, they look like ordinary stars, except for the fact that they don't move as the Earth rotates, as if they were creepily staring at us the whole time (which they probably are, though the government denies it). They're calibrated so precisely that they don't experience any drag or friction, which means that they won't come down for literally billions of years. That's some enviable stamina.

Now imagine the scenario that scientist and photographer Trevor Paglen proposed in 2016 while studying these objects: A thousand generations after the fall of civilization, a new society (be it human, talking dog, or whatever) emerges from the dirt, survives its medieval period, and enters an Enlightenment. Some future Galileo analogue invents a telescope and points it to the sky in the hope of figuring out how the Solar System works, perhaps already harboring the suspicion that we're a speck of dust in an infinite cosmos of orbiting spheres ... only to get confused by the fact that a whole bunch of stars never move at all. He throws his (correct) telescope out the window and becomes a flute player.

We Might Create Color-Changing Cats To Keep Future Humans Away From Nuclear Waste

If history is anything to go by, human beings a mere couple of thousand years from now are going to be completely unable to understand our current language. Ever tried to read Beowulf? That shit was English at some point, but now it looks like your friend sat on their phone with the chat window open.

You know what doesn't change so quickly, though? Nuclear waste dumps, which will remain unsafe for tens of thousands of years. And this begs the question: How the hell do we keep humans away from there long after we've ceased to be able to interpret contemporary "Do Not Enter" signs? One of the fears is that no matter what symbols we come up with, future humans are going to interpret them to mean "buried treasure," because the various "holy fuck seriously do not dig here" signs posted by ancient Egyptians didn't work so well on Europeans.

Scientists have been giving this conundrum a lot of thought lately, and they've been coming up with some truly bizarre ideas about how to communicate danger through the eons without using language. For example, we could plausibly genetically engineer a race of Technicolor cats. This idea isn't as insane as it sounds. Or OK, maybe it is, but it's one that they've been seriously considering. Because cats are likely to remain ubiquitous companions of humankind until the end of our species, if we could engineer them to change color in the presence of radioactive material, theoretically, future humans might learn to associate such color-changing felines with danger and stay the hell away. That or we'll think they're witches and burn them all.

The Ray Cat Solution

Other ideas include trying to create some type of religion, a so-called "Atomic Priesthood" which keeps future generations away from waste dumps, like the guardians in the non-Tom-Cruise version of The Mummy. Others suggest we could cover waste sites in a "Landscape of Thorns" -- fields of jagged, impassable, ominous stones that would make excavation both difficult and frightening. Future people might think we're dicks, but hey, at least their dicks won't fall off.

The Hoover Dam Was Designed To Be The Great Pyramid For Future Ages

Of all the monuments that humankind has created during its dominion over the planet, one of the most, uh, monumental, is Arizona's Hoover Dam. It's estimated that it'll keep chugging away for around 10,000 years, even if a catastrophe knocks back our civilization an era or three and we forget what it is. Should that happen, future civilizations are going to ask a lot of questions about this place and its weird-ass artwork.

See, the Hoover Dam site is lousy with sculptures by Norwegian-American artist Oskar J.W. Hansen, who was commissioned by the state government to create some artwork that would transform the Dam from just another public works project into a downright Wonder of the Modern World. And Hansen did precisely that, decorating the dam with sculptures like two 20-foot-tall bodybuilders made of bronze with wings on their backs. According to Hansen, they represent "the immutable calm of intellectual resolution, and the enormous power of trained physical strength, equally enthroned in placid triumph of scientific accomplishment."

Hansen had greater aspirations for the dam than it being a big power station. He compared it to the Great Pyramid, and wanted it to stand as an equal testament to mankind. And like the Great Pyramid, he covered it in hieroglyphics that nobody will be able to understand now that he's too dead to explain them. On top of the Sphinx-like Winged Figures, the dam is decorated with bas-reliefs ...

Mount Rushmore Will Be The Last Monument To Humanity

Flash forward seven million years from now. Humankind is gone. Either we Mad Max-ed ourselves into oblivion or blasted off into space and left our dying planet to its fate. By this time, the Earth has swallowed every trace of our once-great civilization. If aliens ever visit our world long after we have perished, only one solitary monument will remain. And that is ... American jingoism, baby!

According to the scholars who study the legacy of humanity long after it's perished, the presidential carving at Mount Rushmore, South Dakota is likely to be the last human construction that remains after the Earth's natural housekeeping processes blow away every other trace of our existence. The dirt, sand, and oceans will sink our cities beneath the ground, but Washington, Jefferson, Roosevelt, Lincoln, and anyone else we add (Kanye?) will continue to stare down at a planet otherwise swept clean.

That's because the Black Hills, where the monument is, happens to be one of the most tectonically stable places on Earth. On top of that, the statues are carved out of solid Precambrian granite, one of the toughest naturally occurring rocks on the planet. According to science writer Alan Weisman, author of The World Without Us, the faces on Mount Rushmore will be recognizable for around 7.2 million years, barring some freak event like a direct asteroid collision or alien death ray.

And this isn't a coincidence. The sculptor, Gutzon Borglum, chose the site specifically so that the sculpture would "last forever." In fact, he even specified that the statues should be three inches thicker than the ideal measurement, so that the natural erosion would take a few million years longer. He was pretty fond of presidents and/or faces.

Future Alien Explorers Will Probably Assume We Were A Burrowing Species

Let's look forward to around a hundred million years after we disappear. Even Mount Rushmore is gone. Earth looks like a brand-new planet never before touched by intelligent life. Would some alien visitor ever know that we were here? They probably would, but they would likely assume that we were some kind of giant Dune Sandworm-like creatures, due to our final legacy: a whole bunch of tunnels.

Why tunnels? Because natural environmental erosion tends to erase everything on the surface fairly quickly if people aren't around to maintain it -- like shaking an Etch-a-Sketch, but really slowly and measured in geological epochs. Under the ground, however, such erosion doesn't occur. In fact, an important factor in the science of geology is studying the tunnels dug by burrowing creatures such as worms, rabbits, moles, and woodchucks, since these burrows remain there long after the animals that made them have been relegated to evolution's dustbin.

Well, for all intents and purposes, human beings are a burrowing species too, though on a much greater scale. Animals might build tunnels and burrows, but we build subways, boreholes, and mines. The (sexy) term for this is "anthroturbation," and it will be the last evidence that we existed. Things like the Salt Lake City mines and the London Underground will probably remain until the end of the Earth itself. This brings up an interesting point for those searching for alien life: Instead of looking for alien cities and giant Mars faces, we should probably be looking for evidence of ancient extraterrestrial subway systems.

In A Bizarre Twist, Scientists Are Going Back To Recording Our Knowledge On Stone Tablets

No matter how long human civilization continues to trundle along, future archaeologists who try to get a glimpse of our world will probably assume that we were all wiped out sometime in the late 20th century. After all, that's when we stopped writing things down. Digging up fossilized computers won't do our future descendants any good, because no data on those machines will be recoverable. In fact, as we've covered before, we'll be lucky if we can interpret today's computer software 50 years from now, let alone in a million years. The digitization of information and the large-scale purging of hard copies has made all of human knowledge compact and convenient, but it also put an expiration date on all of that stuff. If we vanish tomorrow, then the totality of our combined human knowledge will last only as long as the batteries in our Kindles.

With this in mind, some scientists have decided to go full circle, preserving the legacy of human knowledge using the best method we've ever figured out: etching it on stone tablets and burying it in the desert.

Memory Of Mankind

The Memory of Mankind Project intends to utilize the one technology that mankind has gotten progressively worse at over time -- data storage -- and etch as much of our knowledge, history, popular fiction, and culture into the surface of a number of ceramic plates, which they will then bury deep in an abandoned Austrian salt mine. Millions of years hence, the hope is that our future descendants will stumble across a treasure trove of ancient plaques which will teach them everything from modern calculus to the relativity formula to the recipe for a really great chili to ... Pepe the Frog.

Yeah, the MoMP people aren't the only ones seeking to create an eternal ceramic legacy to mankind's "achievements." In 2017, the website 9Gag also bankrolled a project to bury a carved stone tablet deep beneath the Earth for the benefit of future generations. But far from the collected enlightenment of a foregone past, its purpose is to record internet memes. You know, like Dickbutt, Philosoraptor, and Pen-Pineapple-Apple-Pen. On second thought, we deserve oblivion.
