    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

    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.

    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.

          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.

          That’s just exponentials coming into play. Area vs mass.

          A micrometeorite can sure fuck up an astronaut at orbital velocities.

    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.

    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.

        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.

            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.

    I defy OP to link me to a source of someone both:

    1. unironically making fun of Superman for having a rock as his weakness, and

    2. not already being challenged immediately on their statement within that same source

    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.

      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.

      And 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.
