plutonium is also poisonous beyond the radiation it emits.
Not only a single type. There is a lot of toxic or radioactive elements in nature
Yeah but uranium kills you after a bit, kryptonite takes him out instantly.
If that was the case, Superman would have died more than once.
I’ve not read the comics but I imagine hr has, a few times?
I remember in a Lobo comic, Lobo grips a chunk of Kryptonite in his fist as he punches straight thru Superman’s chest and heart, right out the other side! Don’t fuck with the Main Man!
Did he die though?
I only know of 1 time and kryptonite wasn’t even used. Doomsday just beat him to death.
Depending on the writer, there are three consistent kryptonite types:
Green weakens him, but overall it doesn’t kill him. Strips his powers, makes him faint or just weak and nauseous.
Blue just takes his powers away either temporarily or permanently
Red intoxicates him or enhances his impulsiveness/brashness
There are others, but they kind of shift of just don’t exist in the main canon
Doesn’t kryptonite just rob him of his power and severely weaken him? It’s like uranium both the time accelerated.
Arsenic and mercury, both commonly occurring metals present in rocks, can kill humans immediately. Especially if vaporized. Uranium can kill and disable quickly in high enough concentrations.
Also, keep in mind it’s a plot device about a fictional flying space alien with laser eyes. It doesn’t need to follow the laws of physics.
it only weakens him, longer exposure can kill him. blue can negate his powers, red makes his inhibitions less. theres also gold and black(synthetic)
I mean yes, but so is to much air, to little air, time, gravity, the sun, pointy sticks, our own biology every form of life in existence and failure to poop correctly.
Most rocks are my weakness, if thrown hard enough
- get near the white house
- stop time
- summon a 1lb rock of pure polonium 212
- resume time
- profit
I don’t understand. The point isn’t that we are not vulnerable to something similar, it’s that Superman is nearly invulnerable. So, my brother in Christ, this is not a retort.
Exactly. I don’t claim to be some sort of super man
Rock + Isaac Newton = death
If we’re talking pure elements at room temperature, people can die from extended contact/eating/breathing beryllium, fluorine, phosphorous, hlorine, chromium, cobalt, arsenic, cadmium, antimony, cesium, mercury, thallium, lead, bismuth, polonium, radium, thorium, uranium, plutonium, and americium. That doesn’t even count all of the heavier than air gases that will kill you in a couple of deep breaths. People are very squishy and prone to getting injured by things.
Would have been a more useful list if OP had excluded eating, since humans can be killed by eating almost everything not intended as food.
Eating a “normal” rock might kill you too depending on the size/shape/sharpness and how quickly you can get medical attention.
Good point!
Also, if you throw them hard enough, all the other elements will kill you too.
Depleted Uranium APFSDS Round says Hello!
You can brain anyone with a rock.

I forget the exact number but a surprising amount of fellas are also confident about winning a fist fight with a bear, so, yeah. This makes sense.
Bears can’t make a fist, so they’re at a disadvantage. Now if it were a claw fight, we might be in trouble.
I means it’s simple really. As the bear charges, I dodge to the side, aim for the eye and with a quick jab…get mauled and die painfully
Bro, I will use my 3 months of bbj to slip behind the bear and put him in a rear naked choke. That’s right, I am going bear back.
This is the moment I wake up from a mix of blood loss and concussion from one swipe of his paw.
I’m sure I could outrun a koala bear. Which isn’t fighting, and koala’s aren’t bears, but I totally could!
Also, technically, I can beat any bear in a fistfight, because bears can’t make fists and would thus be disqualified immediately upon disemboweling me!
… Koala bear wins in the long run via giving you chlamydia.
Yeah but I’m not super. How’s he supposed to call himself super if he’s weak to the same shit I am.
Anything solid of decent mass can basically do us in. A glass bottle with an I love Kitty logo on it at 70mph right to the skull for example. So yeah, a rock, so long as it is large enough, could do it.
It’s all about the joules imparted.
A small enough rock going fast enough is just as deadly as a large one traveling slower.
Below the mm size it does get harder to make something deadly.
That’s just exponentials coming into play. Area vs mass.
A micrometeorite can sure fuck up an astronaut at orbital velocities.
Yeah but that’s in near vacuum.
If you make a piece of dust of about 1microgram fly to someone at about 99% of c, or about 290’000km/s, with Ek=(1/2)mv², we get an energy equivalent to 42’050’000J, or about 10kg of TNT.
The dust would probably vaporise instantaneously, so it would be the resulting explosion that would be deadly if you fired at point blank range.
But if you find a dust accelerator that can get enough power for that. It stays technically possible.
Someone stuck their head into a particle accelerator remember?

In general you need to be in vacuum for any of this to work because a small mass has a small mean free path in atmosphere.
Hmm what if it didn’t have the hello kitty logo?
Nice try but I eat Uranium for breakfast.
I think we all eat Uranium for breakfast.
Speak for yourself, I eat cyanide and hydrogen
That’s just so many calories.
