  There’s enough microbes in any living thing that some decay will happen, for a while at least…

    Wouldn’t all your cells/microbes/bacteria, etc all burst due to the pressure difference? Between that and the frigid cold, I can’t imagine it would go on “For a while” but I don’t know shit

      The pressure isnt violently different (it’s only 1atm. Scuba divers can go up to 70atm with special breathing equipment). The issue is the boiling point of water is very low at that pressure, but on a cellular level the physics of that are going to be different.

      Also space being “cold” is a bit of a misconception. Your body produces heat constantly, and it’s hard to dissipate heat in space, since you can basically only radiate it out as infrared light, which is a much slower process than being in physical contact with something.

      In fact, we use vacuum chambers to insulate things such as in those metal thermoses that they tell you not to put in the dishwasher.

      So being in space would actually be more like being wrapped in the thickest possible blanket than being cold.

      Hollywood showing things instantly exploding or shattering the second they hit a vacuum does that to us, but the actual physics of space and the biology of cells are a lot tougher than the films make it seem.

      Neither the human body nor the bacteria inside it would burst, and the cold space environment behaves much differently than some expect lol

      The pressure difference between the inside of a human body and the vacuum of space is exactly 1 atmosphere (which is not that much in the grand scheme of things).

      And bacteria are tiny tanks, because they are microscopical, the physical forces acting on them are minuscule. Scientists have tested exposing bacteria directly to the vacuum of space outside the ISS, and many species survived for years.

      And about the cold, because space is a vacuum, counterintuitively, heat is actually hard to lose lol, it can only escape slowly through thermal radiation (there is no cold air to whip past and steal heat away), so they would still be gradually working for some time. And even when finally reaching extreme cold, we usually think of it as destructive, but for microbes it’s actually “preservative”. When Labs want to keep bacteria alive for decades without them changing or dying, they freeze them. So a lot of them wouldn’t even die, but stay “suspended”.

  Yea but things do turn into a mist, eventually…

  I mean. Technically Earth is in space, and everything decays…

  Can’t return to the earth if you’re in space :( no bacteria or soil to feed.

  We should have cellars or fridges that recreate the vaccum of space so we can store food indefinitely.

    We do! Scientific freezers are vacuum insulated. You probably don’t want to know what they cost, but it’s a good way to get to -80C. Not much going on at that temp.

      I have been pricing out my ice cream business in case I decide to do that and need a loan. Tell me more about these fancy freezers

  But your spine is slowly being pulled apart Dx

    Sounds actually relaxing

      From what I have been told, astronauts grow a couple of centimeters depending on how long they have been in space. When they come back to earth they shrink over time as gravity pushes them back together.

      I’m glad you find it relaxing because I find it freaky af xD

  And then you meet that one other rando talking about the delicate balance of our microbiome, and you have the best night ever googling random shit in the one quiet room

  Oh, I was thinking “space” as in time and space. About to argue how, by that logic, nothing happens in space.
