Why is this cropped and scrubbed so that we can't see who the original artist is?

[โ€“] salvaria@lemmy.blahaj.zone 2 points 2 hours ago* (last edited 1 hour ago)

Looks like the original source is @mushroommovie. The scrubbing seems to have removed a boredpanda watermark.

That's the toxic positivity people are talking about!

So mushrooms are made of atoms...but then if a mushroom feeds an atom a proton, the atom grows into a bigger, stronger mushroom ๐Ÿค”

I wonder how powerful Mario would get if he took that mushroom (cloud)?

[โ€“] petersr@lemmy.world 5 points 2 hours ago

And in classical enriched uranium fission, atoms would be "fed" neutrons, not protons. So nothing makes sense.

Science is fascinating.

And the positivity ninnies will still try to spin that as something positive.

I thought a heavy nucleus needs an extra neutron for it to go poot.

So to make a nuclear bomb, all we need are some atoms and mushrooms. Got it, will try later.

dont forget the surplus proton

Can you cause fission with protons instead of neutrons?

[โ€“] Digit@lemmy.wtf 4 points 3 hours ago

Maybe need an accompanying alternative version of the cartoon, "be more neutral".

[โ€“] gnutrino@programming.dev 2 points 4 hours ago

Yes if they have enough energy (see for example https://www.nature.com/articles/s41598-020-74045-5). What you won't get with proton-induced fission is an explosion as the fission doesn't emit protons which can go on to cause further fissions so there's no chain reaction (unless you already have a critical mass for normal neutron-induced fission in which case it's going to explode even without the protons).

If you're adding a proton wouldn't it be fusion? Which also releases a bucket load of energy.

[โ€“] SmoothOperator@lemmy.world 8 points 5 hours ago

The largest amount of energy is released from fusing two hydrogens into helium. The atom in the comic looks much heavier than hydrogen.

Also a chain fusion reaction is required for an explosion. The comic just shows non-explosive ionisation.

[โ€“] ryannathans@aussie.zone 5 points 5 hours ago

It looks like a heavy element so fusion would be net negative energy

[โ€“] zxqwas@lemmy.world 3 points 5 hours ago

Possibly but the common fusions are using isotopes of H, He, Li with some amount of neutrons, not naked protons.

Heavier elements as the big blob is releases a lot less energy, and the really heavy ones are not exothermic.
