You’ve probably said it while standing in a slow-moving line at the DMV or waiting for a massive game update to download. "I’m going to have to wait a million years for this." It’s our favorite hyperbole. We use it to vent frustration because, honestly, a million is just a big, round number that sounds like "forever" but with a bit more punch.
But if you actually sat down and tried to wrap your head around what that duration looks like, your brain would likely just... quit. Humans aren't wired for this. Evolutionarily, we care about the next ten minutes or maybe the next season. Thinking about 1,000,000 years isn't just a fun philosophical exercise; it’s a confrontation with the sheer scale of the universe that makes our entire civilization look like a blink.
Seriously.
The Math of Why We Can’t Comprehend a Million Years
Numbers are weird. We can count to ten easily. We can visualize a hundred people in a room. But once we hit the "millions," our brains treat it as a vague blob of "a lot." If you wanted to literally wait a million years by counting seconds, you’d be counting for about 11 and a half days just to hit a million. That doesn't sound too bad, right? But that's just seconds.
If you were waiting for years, you’re looking at a span of time that stretches back ten times further than Homo sapiens has even existed in our modern form. To put it in perspective, 2,000 years ago was the height of the Roman Empire. Multiply that by 500.
That’s the gap.

Geologists like Marcia Bjornerud, who wrote Timefulness, argue that our "chronophobia" or fear of deep time actually hurts how we treat the planet. We operate on fiscal quarters and election cycles. Meanwhile, the Earth is operating on a clock where a million years is basically a long weekend. When we say we’ll wait a million years, we’re accidentally referencing the "unit" of time that defines the very mountains we walk on.
What Happens to the Earth While You Wait?
If you actually had to wait a million years, the world you stepped back into would be unrecognizable. It wouldn't just be "different tech." The geography itself would have shifted.
Plate tectonics are slow, but over a million years, they’re relentless. The Atlantic Ocean would be wider by about 25 kilometers. That doesn't sound like much until you realize that every single coastline on Earth would have shifted, eroded, or been submerged.
Then there’s the sky.
The "fixed" stars aren't fixed. Over a million years, proper motion means the constellations we know today—Orion, the Big Dipper, Cassiopeia—would be completely distorted. They’d be gone. You’d be looking at a totally alien night sky.
- The Red Supergiant Betelgeuse will almost certainly have gone supernova by then. If you’re waiting, you’ll see a light in the sky as bright as the full moon for a few weeks, then... nothing. A hole in the shoulder of Orion.
- Glaciation cycles will likely have kicked in. Depending on how our current carbon experiment goes, we might be deep into a new ice age or recovering from a massive thermal spike.
- Niagara Falls will be gone. It erodes at a rate that suggests it will fully disappear into Lake Erie in about 23,000 to 50,000 years. A million years? It’s a distant memory of a geological hiccup.
Space Junk and the Ghosts of Humanity
What stays behind? If you decided to wait a million years, what would be left of us?
Surprisingly, not our skyscrapers. Most of our steel and glass cities would be dust within a few thousand years without maintenance. The "ruins" of New York or London would be unrecognizable mounds of vegetation-covered rubble.
The real survivors?
- The Moon Equipment: The descent stages of the Apollo Lunar Modules and the footprints left by Neil Armstrong and Buzz Aldrin. Without wind or water to erode them, they could potentially last millions of years, though micrometeorite bombardment will eventually sand them down.
- Nuclear Waste: The deep geological repositories, like Onkalo in Finland, are designed specifically to keep spent nuclear fuel safe for 100,000 years. To wait a million years is to outlast our most dangerous trash.
- The Voyager Golden Records: These are currently hurtling out of the solar system. In a million years, they’ll still be out there, drifting through the vacuum, carrying our music and greetings to a silence that might never answer.
It’s kinda humbling. Most of what we think is "permanent"—our books, our hard drives, our monuments—is incredibly fragile. Digital data on a modern SSD might last ten years without power. Stone carvings might last ten thousand. To reach a million, you need something special.
The Biological Shift: Evolution Doesn't Stop
A million years is enough time for significant biological evolution. If you were in a time capsule, the "humans" who greeted you on the other side might not even be the same species.

Think about it.
One million years ago, our ancestors were Homo erectus. They used fire and made stone tools, but they weren't us. They didn't have our brains, our language, or our complex culture. If we assume the same rate of change, the beings living on Earth in the year 1,002,026 will look at our skeletons the way we look at "Java Man."
And that’s assuming we don't use technology to speed things up. With CRISPR and neural interfaces, the divergence could happen much faster. Or, perhaps more likely, the dominant "life" isn't biological at all.
Digital Immortality and the Million-Year File
We’re currently obsessed with "long-term" thinking. The Long Now Foundation is building a clock in a mountain in Texas designed to tick for 10,000 years. That’s a drop in the bucket.
If you want to make a piece of information last so someone can read it after they wait a million years, you can't use a USB stick. You have to go back to basics.
Researchers at the University of Southampton have developed "5D data storage" using nanostructured glass. They’ve successfully encoded the Universal Declaration of Human Rights into a glass disc using ultrafast lasers. They claim it can remain stable for 13.8 billion years at temperatures up to 190°C.
Finally, a way to make sure our memes survive the heat death of the sun.
But who is going to read it?
That’s the part that gets weird. Language changes so fast that Old English (from just 1,000 years ago) is basically a foreign tongue to most people. In a million years, any language we speak today will be as dead as the vocalizations of a trilobite. To communicate across that span, you have to use math, or physics, or universal constants.

Why We Should Actually Care About This Scale
It feels like a game, but thinking about what it means to wait a million years is actually a vital mental tool. It's called "Deep Time Thinking."
Most of the problems we face—climate change, plastic pollution, biodiversity loss—are "slow" problems. They don't fit into a 24-hour news cycle. When we realize that a plastic bottle takes 450 years to break down, that’s just the beginning. The chemical legacy of our industrial age will be written in the rock strata for millions of years.
Future geologists will see a thin layer of "technofossils"—microplastics, concentrated isotopes from nuclear testing, and a weird spike in chicken bones (because we eat so many of them). They'll call it the Anthropocene.
Practical Insights for the Time-Stressed
If you're feeling overwhelmed by the idea of such vast spans of time, or if you're just annoyed that your Starbucks order is taking five minutes, here is how to use the "million-year perspective" to your advantage:
- The 10-10-10 Rule (Extended): When you're stressed, ask: Will this matter in 10 minutes? 10 years? 1,000,000 years? Usually, the answer to the last one is a resounding "no," which is strangely liberating.
- Invest in "Deep" Media: If you want to leave a legacy, don't rely on the cloud. Print your favorite photos on archival paper. Carve something in stone. Write a letter. Physicality is the only thing that stands a chance against the clock.
- Acknowledge Your Blip: Realizing we are a tiny part of a massive story doesn't make us insignificant; it makes us incredibly lucky to be here for the brief flash of light that we get.
- Support Long-Termism: Look into projects like the Svalbard Global Seed Vault. These are the rare instances where humans are actually trying to build things with a "wait a million years" mindset.
Waiting a million years isn't just a long time. It's a complete reset of the world as we know it. The mountains will move, the stars will shift, and every single thing you currently worry about will be dust.
Next Steps for Deep Time Exploration:
- Visit a Local Outcropping: Go find a rock formation near your house. Look up its age on a geological map. If it’s 300 million years old, realize that you are standing on something that has already survived three hundred "million-year" cycles.
- Read "Timefulness" by Marcia Bjornerud: It’s the best primer on how to think like a planet rather than a person.
- Check out the Long Now Foundation: Watch some of their seminars on YouTube about building things that last beyond our lifetimes.
- Audit Your Digital Life: Pick one thing you want your grandkids (or their grandkids) to see, and find a way to make it physical.
The clock is ticking. But in the grand scheme of things, you've got all the time in the world. Sorta.
