The Riddle That’s Literally About Nothing
What gets bigger when you take something away? If you answered “a hole,” congratulations!
You’ve just won a free existential crisis. Because according to physicists, the real answer might be “the entire universe collapsing into a vacuum-shaped black hole of doom.”
But don’t panic yet - it’ll only happen in 10^790 years.
That’s a 1 followed by 790 zeros. For perspective, that’s roughly how many times you’ll check your phone before finishing this article.

Let’s start with the basics: the vacuum.
Not the Dyson you regret buying on Black Friday.
No, we’re talking about space itself - the vast, empty, “nothing” that makes up 99.9999999% of the universe. Except, as it turns out, the vacuum isn’t empty.
It’s more like your teenager’s bedroom: superficially empty, but seething with chaotic energy, rogue socks, and particles that pop in and out of existence like uninvited guests at a quantum rave.
The Vacuum - Nature’s Most Overcrowded Empty Room
Imagine throwing a party. You invite no one. Yet somehow, the room is packed with people eating your chips, spilling drinks, and arguing about the laws of thermodynamics. That’s the vacuum. Thanks to quantum mechanics, particles and antiparticles are constantly blinking into existence, having a quick tango, and vanishing again.
These “virtual particles” are the universe’s version of that one friend who says, “I’ll just stay for five minutes!” and then borrows your car.
Why does this matter? Because all that quantum chaos gives the vacuum energy. Think of it as the universe’s secret battery, quietly powering… well, nothing useful. Unless you count the potential to obliterate reality.
The Universe Is Sitting on a Wobbly IKEA Chair
In the 1970s, physicist Sidney Coleman dropped a truth bomb: the universe might be in a “false vacuum.” Picture this: you’re sitting on an IKEA chair that’s mostly stable. It’s held together by hope and a single screw you forgot to tighten. That’s our universe. Stable enough… until it isn’t.
The “false vacuum” is like that chair. It’s metastable - a fancy word for “it’ll probably hold, but don’t lean back.” If the universe slips into the “true vacuum,” everything - atoms, coffee cups, TikTok influencers - will be rewritten by new physics.
The catch? This could happen anytime in the next 10^790 years. So, relax. You’ve got at least until next Thursday.
Quantum Toasters and the 5,564-Qubit Time Machine
Enter the heroes of our story: a team of scientists from Leeds, Jülich, and ISTA. They wanted to simulate the end of everything, but they didn’t have a universe-sized lab. So they used a D-Wave quantum annealer - a machine I like to call the “quantum toaster.” It’s not a full quantum computer; it’s more like a bread maker that occasionally solves spacetime riddles.
This toaster has 5,564 qubits. Qubits are the quantum version of bits, except they can be 0, 1, or both - like Schrödinger’s cat, if the cat also had a side hustle in blockchain. The team programmed these qubits to mimic the false vacuum, then watched as quantum bubbles (think: cosmic soap bubbles) began to form.
Bubble Trouble - Pac-Man Meets Black Friday
Here’s how vacuum decay works:
-
Bubbles of true vacuum pop up randomly, like notifications on your phone.
-
Big bubbles eat small bubbles, Pac-Man style.
-
Once a bubble gets big enough, it expands at light speed, rewriting physics as it goes.
In the simulation, tiny bubbles “danced” without growing - imagine toddlers on espresso. But the big ones? They’re the Karens of the quantum world, absorbing everything in their path. The result? A universe where gravity might suddenly decide “up” is “down,” and your morning coffee could teleport to Neptune.
Why You Shouldn’t Cancel Your Weekend Plans
Before you stockpile canned beans, remember: the odds are laughably low. 10^790 years is way longer than the DMV’s hold time. As study author Zlatko Papić says, “We need better experiments… or maybe a really long Netflix queue.”
But here’s the kicker: this research isn’t just about doomsday. Quantum simulators could revolutionize tech - from unbreakable encryption to batteries that don’t die after two Zoom calls. So, while the universe might end, at least your phone bill won’t.
Enjoy Your Coffee (While Space-Time Allows)
In summary: the universe is a precarious IKEA chair, quantum bubbles are hungry Pac-Men, and your existence is a rounding error in cosmic probability.
But hey, look on the bright side!
You’ve just learned more about vacuum decay than 99% of humans, and that’s a great party trick.
So go live your life! Hug a friend. Adopt a cat. Drink that overpriced latte. Because in 10^790 years, when the universe finally coughs up a quantum hairball, you’ll be ready.
Fin.

How the universe might end—not with a bang, but with a quantum bubble bath! Using analogies like IKEA chairs, excited toddlers, and the cosmic Pac-Man, we analyze how physicists simulated “vacuum decay” using a 5,564-qubit quantum toaster.
Spoiler: You have 10^790 years to get through your Netflix queue.
