  • It’s roughly evenly distributed throughout the universe. So if you imagine the universe Big Banged into existence at the current size, no expansion, it would be emitted in all parts of space, out of the primordial energy soup, before condensing into matter.

    But that doesn’t really make sense because if you increase the volume you decrease the density, therefore you wouldn’t have the big bang or any background radiation at all.

    But to strictly answer your question, if you picked any one CMB photon you received right now, that photon would probably have been from the edge of the visible universe, ~46.5 billion light years away. The distance would probably be slightly less because our theoretical static universe would not have expanded in the intervening time.


  • low Karma accounts can post in Lemmy as opposed to Reddit

    But should they?

    One of the things I miss about reddit (and slashdot before that) was that if you got downvoted/downmodded a lot in a short amount of time, it would tell you to slow down (, cowboy). It helped to limit the damage when someone would go on a troll spree before they got banned.

    Some subreddits did implement a “you must have x karma to post” rule, or account age, which I wasn’t always a fan of, especially if it was karma within a certain subreddit. I understand the logic, that it was intended to make people read the community before posting, but I’m not sure if it hit the mark. But it did limit brand-new spam accounts, which are already here on lemmy.







  • Pretty sure they still do, as long as you aren’t getting the cheap “everything controlled by one board” models (though the diagram might actually be in the service manual, not in the box).

    Although there is still repairability. I repaired my TV by replacing the speakers. Some years ago I repaired my furnace by replacing the control board.

    Something like a kettle makes more sense for being sealed, though, because it’s water and electricity.
