It honestly depends on how TECHNICAL you're trying to be.

If you're being super well acktually - then zero elements were created by the big bang. It was way too hot and dense and it was only subatomic particles. Everything had to cool slightly, and stuff had to decay slightly, for any elements to be created at all.

Then after that, the VAST MAJORITY of elements were hydrogen and helium, yes, but there was a very small amount of other elements (lithium being the biggest part of that small amount of other elements). The fact that it's a sliver of a percent doesn't matter, the universe is enormous and larger elements, while rare, actually did exist back then.

This deuterium then fused to heavier nuclei, including tritium, helium-3, helium-4, and lithium-7.[2]: 315  Helium-4 has a large binding energy, which means that once a helium-4 nucleus is formed, it is difficult to break apart and incorporate its constituents into heavier nuclei. Therefore matter in the universe is primarily hydrogen and helium-4 after BBN.[13]: 68  Standard BBN predicts, by the time BBN ends, the universe is composed of about 75% of hydrogen and 25% helium-4 by mass. Roughly 1 nucleus in 100,000 is deuterium or helium-3, and 1 nucleus in 1,000,000,000 is lithium-7. Even smaller amounts of heavier elements, as heavy as oxygen-20, have been predicted to form.[10]

So really - there's no reason why some crazy weird elements couldn't have also been created, it's just rare - which is the whole point of "crazy rare super metal - Uru - was created at the beginning of the universe"

Comic Strips is a community for those who love comic stories.

Rules
  1. 😇 Be Nice!

    • Treat others with respect and dignity. Friendly banter is okay, as long as it is mutual; keyword: friendly.
  2. 🏘️ Community Standards

    • Comics should be a full story, from start to finish, in one post.
    • Posts should be safe and enjoyable by the majority of community members, both here on lemmy.world and other instances.
    • Any comic that would qualify as raunchy, lewd, or otherwise draw unwanted attention by nosy coworkers, spouses, or family members should be tagged as NSFW.
    • Moderators have final say on what and what does not qualify as appropriate. Use common sense, and if need be, err on the side of caution.
  3. 🧬 Keep it Real

    • Comics should be made and posted by real human beans, not by automated means like bots or AI. This is not the community for that sort of thing.
  4. 📽️ Credit Where Credit is Due

    • Comics should include the original attribution to the artist(s) involved, and be unmodified. Bonus points if you include a link back to their website. When in doubt, use a reverse image search to try to find the original version. Repeat offenders will have their posts removed, be temporarily banned from posting, or if all else fails, be permanently banned from posting.
    • Attributions include, but are not limited to, watermarks, links, or other text or imagery that artists add to their comics to use for identification purposes. If you find a comic without any such markings, it would be a good idea to see if you can find an original version. If one cannot be found, say so and ask the community for help!
  5. 📋 Post Formatting

    • Post an image, gallery, or link to a specific comic hosted on another site; e.g., the author's website.
    • Meta posts about the community should be tagged with [Meta] either at the beginning or the end of the post title.
    • When linking to a comic hosted on another site, ensure the link is to the comic itself and not just to the website; e.g.,
      ✅ Correct: https://xkcd.com/386/
      ❌ Incorrect: https://xkcd.com/
  6. 📬 Post Frequency/SPAM

    • Each user (regardless of instance) may post up to five (5 🖐) comics a day. This can be any combination of personal comics you have written yourself, or other author's comics. Any comics exceeding five (5 🖐) will be removed.
  7. 🏴‍☠️ Internationalization (i18n)

    • Non-English posts are welcome. Please tag the post title with the original language, and include an English translation in the body of the post; e.g.,
      Sí, por favor [Spanish/Español]
  8. 🍿 Moderation

    • We are human, just like most everybody else on Lemmy. If you feel a moderation decision was made in error, you are welcome to reach out to anybody on the moderation team for clarification. Keep in mind that moderation decisions may be final.
    • When reporting posts and/or comments, quote which rule is being broken, and why you feel it broke the rules.
Banned Artists

The following artists are banned from the community.

  1. Jago
  2. Stonetoss

It should be noted that when you make reports, it is your responsibility to provide rational reasoning why something should be removed. Saying it simply breaks community rules is not always good enough.

Web Accessibility

Note: This is not a rule, but a helpful suggestion.

When posting images, you should strive to add alt-text for screen readers to use to describe the image you're posting:

Another helpful thing to do is to provide a transcription of the text in your images, as well as brief descriptions of what's going on. (example)
