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.
Everybody’s weakness is a rock if you hit them with it hard enough.
Kryptonite lays him out right away even from a reasonable distance.
Even the plutonium demon core won’t kill us right away.
A little touch of hydrogen cyanide and we’re gone though. We’re fragile AF

profitdie. You summoned 1lb rock of pure polonium 212 and stayed.
Damn it, i knew i forgot something🤦♂️
Doesn’t even need to be a magic rock. A regular one thrown at your head also does wonders.
Shit, even a crack rock can do it.
In fairness, Doomsday beat Superman in a straight knuckle dust up, no kryptonite required. So that’s also a Superman weakness.
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.
Hmm what if it didn’t have the hello kitty logo?
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.
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.
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.

In Superman The Animated Series Batman (and the Joker) discover that a jade dragon is actually made out of kryptonite because the owners die after a few months.
And in some of the stories Lex Luthor loses his hair because of his kryptonite experiments.
So at least in those universes it’s also harmful for humans.
Lex and Superboy are friends until Lex starts and gets caught in a chemical smoke party, which Superboy blows out with his super breath. In the process, he blows smoke into Lex Luthor’s hair, which falls out. Then Lex swears to, “use all of my scientific genius to one day destroy you.”

Overall rating: 10/10. No notesAnd in some of the stories Lex Luthor loses his hair because of his kryptonite experiments.
In Smallville, the spacecraft carrying Superman brings a kryptonite meteor swarm with it. Lex’s exposure to the meteors is the cause of his premature baldness and a partial reason for his resentment of The Alien.
And in some of the stories Lex Luthor loses his hair because of his kryptonite experiments.
In the mainline comics of the ‘80s and ‘90s, wearing a kryptonite ring day after day gave him incurable cancer.
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.
Also, if you throw them hard enough, all the other elements will kill you too.
Depleted Uranium APFSDS Round says Hello!
Eating a “normal” rock might kill you too depending on the size/shape/sharpness and how quickly you can get medical attention.
Good point!
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.
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.
Ah man I’ve not heard Kryptonite in years
I have a short playlist of Superman songs.
- Kryptonite - 3 doors down
- Jimmy Olsen’s Blues - Spin Doctors
- Superman (Its not easy) - Five for Fighting
- Superman’s Dead - Our Lady Peace
- (Wish i could fly like) Superman - The Kinks
- Superman - REM
Always looking for more.
What about “(I’m No) Superman” by Lazlo Bane, aka the Scrubs theme song?
How could you miss Superman by Goldfinger
You Don’t Mess Around With Jim by Jim Croce isn’t directly about him but does give good advice on treating this wardrobe with respect.
Silvergun Superman - stone Temple pilots
Sunshine Superman - Donovan
Superman’s Song - Crash Test Dummies
I sing it to my son at bedtime.
You forgot the best one: Kashmir - Bring back Superman
Superman - Love Spit Love
No One Likes Superman Anymore - I Fight Dragons
Hero 77 - Bombay Street
Mentions batman, superman, spiderman, Mr incredible, but it’s not a song about them.
Scrubs theme song - Superman - Lazlo BaneAlready covered
It’s so strange that nobody did a good music video for that song with scenes from Man of Steel. I always thought that one would fit great. There’s a Smallville one but I don’t like it very much.
Nice try but I eat Uranium for breakfast.
That’s just so many calories.
I think we all eat Uranium for breakfast.
Speak for yourself, I eat cyanide and hydrogen
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.
What I wonder: according to lore the conditions, where supermans people live, on krypton are so harsh that they are a strong race that is like humans under those conditions.
Now sth. With the sun is there too, but lets put that aside for a moment.
So Supermans weakness is a rock of krypton. Because the rock itself must be super radioactive or sth like that.
Anything that harms superman should kill every human in the area instantly.
Must be super radioactive…
Should kill every human in the area instantly
Counterpoint: What if Superman has an element in his body that is crucial to his makeup that is specifically destroyed/harmed by the radioactivity, while that radioactivity passes harmlessly through any other element?An anti-krypton element of sorts, if you will.
Krypton, for example, could be emitting a wave with incredibly low amplitude, but incredibly high frequency. This combination would struggle to make contact with the atoms in normally-dense objects here on Earth, but would strike an ultra-dense object like anti-krypton like a truck.
Theoretically possible, but doesn’t work with our current understanding of physics.
However when you add aliens and other magic bs it doesn’t matter what physics say. So your explanation could actually work here.
Doesn’t work with our current understanding of physics.
Hang on I can nerd this harder. It could sort of work if it’s a data signal that exists as noise which disrupts the nervous system of a Superman, but is ignored by the nervous system of a Human.
Damn you are good. Lol
Dude it’s comic book magic and bullshit, don’t overthink it.
Exactly. I don’t claim to be some sort of super man
“What if I pretend like people are saying something stupid and then cleverly refute it? Yes, that will make an excellent meme.”
Yeah but I’m not super. How’s he supposed to call himself super if he’s weak to the same shit I am.
