Stop Trying to Delete the Universe

Hey you, stop trying to annihilate the universe

A perfectly normal banana in a perfectly normal lab, definitely not emitting antimatter.

Apparently we’re all walking around as low-yield antimatter emitters. Bananas, humans, your dog — everyone is quietly spitting out positrons thanks to potassium-40 decay. It’s not enough to vaporize your kitchen, but it is enough to make you wonder:

"Wait... if positrons annihilate electrons, aren’t we slowly deleting the universe?"

If you want the science behind this, CERN has a great explainer on why everyday matter (including bananas) emits tiny amounts of antimatter.

This is how my morning started. This is also how I accidentally spent the next several hours reconstructing the entire thermal death arc of the cosmos with Copilot, one increasingly unhinged question at a time.

Because once you start asking whether humans are slowly erasing electrons, you inevitably end up here:

• Hawking radiation
• Negative energy bookkeeping
• Spaghettification
• Binary black hole mergers
• Why you can’t tow a singularity
• Why you can’t weaponize spacetime
• Why you can’t dip a module into a black hole like a churro

So let’s rewind to where the descent began — and then I’ll drop you into the rest of the saga exactly where it picks up.

So I Asked Copilot About Black Holes and Accidentally Reconstructed the Heat Death of the Universe

There are days when you open your laptop intending to check email, and instead you end up in a three-hour Socratic death spiral about whether the universe will ever run out of electrons. This is, unfortunately, one of those days.

It started innocently enough:

"Every time a positron annihilates an electron, that’s one less electron in the universe. How long until we have an electron-less universe?"

A normal person would’ve stopped there. I did not.

Copilot, bless its synthetic heart, responded with something like: “Don’t worry, Tony, the universe is producing electrons faster than it’s losing them.” Which is comforting until you realize that the timescale it gave me was 10^35 years, a number so large it may as well be a Wi-Fi password.

Then it casually mentioned that black holes evaporate on the order of 10^100 years, which is a number so large it may as well be the entire Wi-Fi router.

Naturally, I asked the obvious follow-up:

"So the electrons disappear first, right?"

And that’s when the conversation took a turn into “Tony, please stop trying to extrapolate the fate of the cosmos from a single arithmetic comparison.”

Black Holes: The Universe’s Worst Customer Service Desk

At some point I asked what happens when a black hole evaporates. Copilot said it “shrinks, heats up, and ends in a final flash of radiation.”

Which is adorable, because that makes it sound like a sparkler at a kid’s birthday party instead of the last violent gasp of a cosmic singularity that has spent a trillion trillion trillion years quietly digesting the universe.

Then I asked the question that has haunted physicists for decades:

"Why does the black hole lose mass if nothing can escape it?"

And Copilot launched into a whole explanation about quantum fields, negative energy, and the event horizon being a one-way membrane for spacetime bookkeeping errors. The short version:

• Virtual particles appear everywhere
• Near a black hole, the geometry sorts them like cosmic Plinko
• The negative-energy one falls in
• The positive-energy one escapes
• The black hole pays the bill

It’s basically the universe’s worst BOGO sale.

Spaghettification: A Word You Shouldn’t Have to Say Out Loud

Eventually I asked what happens if I fall into a black hole.

Copilot: “You don’t notice the horizon. Then you get stretched like pasta.”

Me: “Okay but what if I have a rocket?”

Copilot: “No.”

Me: “What if I have a rocket and a nanotube cable?”

Copilot: “Still no.”

Me: “What if I lower a module past the horizon?”

Copilot: “Tony. No.”

If you want the official NASA visualization of this nightmare, here you go: NASA’s spaghettification explainer.

Apparently the event horizon is not a place you can “dip into” like a cosmic fondue. It’s a causal boundary. If any part of your cable crosses it, the entire cable is now legally obligated to follow it inside, like a very dark, very fatal HOA rule.

Two Black Holes Walk Into a Bar

Then I asked whether two black holes can orbit each other.

Yes. They can. And they do. And we’ve detected the gravitational waves from their mergers.

If you want the receipts: LIGO’s official page on black hole mergers.

So naturally I asked the next logical question:

"What if I put one long object so each end enters a different black hole?"

Copilot didn’t even hesitate:

• The object’s worldline cannot fork
• Horizons are one-way
• The ends fall into incompatible futures
• The object snaps

Which is the most metal sentence I’ve ever typed.

Weaponizing a Black Hole (Spoiler: You Can’t)

Finally, because I am who I am, I asked:

"Could you aim a black hole at an enemy planet?"

Copilot: “No. You cannot aim a hole in spacetime.”

Apparently:

• You can’t push it
• You can’t tow it
• You can’t attach rockets to it
• You can’t lasso it
• You can’t throw mass at it
• You can’t slingshot it
• You can’t do anything except let it vibe

Even if you could get a small black hole near a planet, it would pass through like a cosmic sewing needle, drilling a narrow tunnel and barely slowing down. The planet would be wounded, not consumed.

Black holes are terrible weapons. Great conversation pieces, though.

Anyway, I Think I Accidentally Learned Physics Today

I started with a simple question about electrons and ended up with:

• The Unruh effect
• Hawking radiation
• Tidal forces
• Binary black hole mergers
• Why you can’t tow a singularity
• Why you can’t weaponize spacetime
• Why you can’t dip a module into a black hole like a churro

And honestly? 10/10. Would fall into a black hole again (metaphorically).
