  • I’m no expert either but I never got the idea of a new universe popping up everytime. Do other universes also cause popups of new universes or just ours? That’d escalate quickly :-)

    I thought it goes that there’s already infinite universes existing from the big bang on. Otherwise universes would be created without big bang. (The new universe would just pop up and you’d still believe it was created by the big bang but there never was one)

    Also I’m not sure if laws of thermodynamics had to span accross universes. Take two theoretical perfect vacuum/radiation sealed boxes you put an energy source into. There’s no way to communicate between boxes. Each box had it’s own entropy and state of energy. Both would obey the laws of physics while being separate “systems”.

    That thought experiment wouldn’t work, if new boxes had to pop up if one of the boxes wanted to.




  • When you refund a mattress they just surface clean it

    yuck. I doubt that. It’s manual work and far more expensive than a machine.

    but getting them dry would be a challenge

    seriously? I mean, there is a chance no such service exists in your town. Bad luck then. But there is close to zero chance it doesn’t exist in your country.

    What do you think hospitals do? (Or good hotels, as mentioned). Source: Worked in an elderly home that used such a service regularly.

    Here’s an image of such a mattress washing machine.

    They work.


  • That’s not true. All mattresses except the cheapest foam ones are washable (they are, too but they might change properties then). But why get a used cheap one?

    There are mattress washing services with giant washing machines that are used by hotels. Ask hotel staff to find one.

    You can’t get rid of most of the build-up.

    You actually can get rid of all the buildups. Just like with clothes. Also don’t think sellers throw it away when you refund a mattress - they wash it and sell it again.



  • Some things basically come for free when they were used. Washing machine, stoves… Disassembling them to fully clean them takes a day or two, but it’s still faster than buying new and chances are good, someone wants to get rid of their high quality stuff near you and will give it away for cheap if you “dispose” it for them.

    You can even wash a mattress for a few bucks. If it’s good quality, a decade old used filthy mattress can come out like brand new.

    People finding that gross or poorish are the reason, stuff is so cheap










  • I don’t believe a CEO or King is necessary for short sighted action. Humans are just very bad at sustainable long-term decisions.

    I know a guy who owns a small forrest and when wood prices were skyrocketing due to supply chain disruption, he was tempted to sell more wood than planned. So he couldn’t sell as much in the following years. He has no boss, is not rich and makes his own decisions.

    It’s a simple mechanism of supply and demand. I can’t see a reason why people wouldn’t cut down more trees than can grow back when demand is ultra high, other than force/legislation. And then people get angry because they won’t realize that they’d destroy their own business in the long run. A worldwide life-threatening situation won’t change that.
