Fission doesn’t happy because we cut atoms in half. Fission happens because we blast enriched uranium with neutrons, the uranium absorbs a neutron, gets too heavy, and falls apart.

That’s easy to explain, having cut a lot of cucumbers in my life. Since the actual nucleus of an atom is much smaller than the atom including its electrons itself, the probability of hitting the protons or neutrons is so small, that I’d need to live for a few thousand years and cut 1 cucumber per second nonstop, before this scenario happens even once. It is not impossible, just very improbable.

That’s just one way to do it.

I know very little about physics and I’m pretty sure you could cut cucumbers with a knife until the end of time and you’ll never trigger a nuclear explosion.

Actually, it’s because cucumbers are so cool (c.f. cool as a cucumber) that they’re in a ground state. It’s actually endothermic to split their atoms so you don’t get a chain reaction.
Cutting hot vegetables, habernaros for example, is much more risky and adequate precautions should always be taken to avoid radioactivity contaminating sensitive regions of the body.

I thought the only option with cucumbers is to keep mashing them together until fusion, no?
Johanno@feddit.org 2 months ago
Ok if it is theoretically possible to cut atoms bay using metal knives then why didn’t ever a fission happen? I mean if you combine all knife cutting in the whole world since knives exist, the probability should be pretty high.
BennyInc@feddit.org 2 months ago
Well, it probably happened an infinite amount of times already. But the resulting cucumber-detonation just triggers a new Big Bang. We’re on the whatever-millionth reset now. Should end any day now. STOP CUTTING CUCUMBERS, SHEEPLE!!

Well fission of uranium isn’t hard. I want you to see to fission a C atom! XD

Hmm this made me wonder why something like this wouldn’t melt the rock and then sink into the crust and then into the planet. Probably not hot enough.
And that made me think if we could build something like a big pellet of fissile material, encase it in tungsten or something so that it is hot enough to do so but remains stable, and then let it sink into the earth. Maybe that could be tracked? Then we could learn something about how it moves and where it ends up. But probably can’t be tracked since this isn’t star trek 🖖

But what would you do with the sliced cucumbers of millenia?
BennyInc@feddit.org 2 months ago
Dunno. I guess growing them fast enough would also be a problem.
apocalypticat@lemmy.world 2 months ago
You’re assuming the blade would be thinner than the nucleus, at the very least.

Someone let Einstein loose, we must admit that violence is on occasion the only recourse.

Okay, now explain bananas.
BennyInc@feddit.org 2 months ago
Well, that’s why we generally eat bananas without cutting. As everyone knows, bananas are slightly radioactive. This increases the danger when cutting them exponentially, so don’t do that.

The electromagnetic force from the atoms’ respective electron cloud probably help prevent atom get close to each other. And the strong nuclear force also help prevent atom from splitting.
BennyInc@feddit.org 2 months ago
You mean I’m just not cutting strong enough?
Hirom@beehaw.org 2 months ago
Yes

You’re doing it wrong. The mouse just diced a cucumber really, really l, small.
webpack@ani.social 2 months ago
(assuming your post isn’t a joke) it is impossible to cause a nuclear reaction by cutting cucumbers.
the biggest innacuracy in this comic is that as the panel zooms in on the cucumber atoms, the knife looks exactly the same. if it was realistic it would just be a bunch of metal atoms pushing aside a bunch of cucumber atoms, not a sharp knife slicing through individual atoms.
BennyInc@feddit.org 2 months ago
Bro, you should sharpen your knives.

maniii@lemmy.world 2 months ago
Won’t this cause nicks and dulling as sudden heating and impact lead to both knives becoming extremely useless ?
Also replacing one of the knives with a sharpening rod, I can sort of suspend disbelief enough to believe it “possible”.
Paradachshund@lemmy.today 2 months ago
Maybe it’s not zooming in. Maybe the atoms of the cucumber are getting bigger! 😏
beetsnuami@slrpnk.net 2 months ago
Well… that, and one nucleus splitting in half wouldn‘t start a chain reaction in a cucumber, and therefore not release a macroscopically noticeable amount of energy.
Ultraviolet@lemmy.world 2 months ago
To put into perspective just how trivial it is, the actual amount of energy of splitting a single nucleus is on the order of picojoules. The shock from touching a doorknob is a few millijoules, literally millions of times more powerful.

The Subtle Knife is definitely so sharp that it cuts through dimensions, so I think it would cut atoms.
So really that just means it’s not inaccurate, it’s just a very specific, fictional knife!
