    You can shine a flashlight through your entire hand, OP. Light probably reaches most of your interior at least in small amounts.

      If you count light outside of the human visible spectrum then it is definitely bright in there.

        Everything is glowing all the time. At human body temperature, you’re glowing mostly in the infrared.

        If you count light outside of the human visible spectrum, it’s bright pretty much everywhere. Like, getting away from light requires specially constructed facilities.

    It’s definitely more than 1 molecule thick. CG people call it sub-surface scattering.

      Sub-Surface scattering is the whole reason flesh-toned plastic looks so fake.

        Nah, sss is the phenomena they are trying to capture. When we comparing it to reality, i.e. the intended results, it looks fake because they haven’t figured how to model it such that it both looks good and renders in a reasonable amount of time. CG milk looks like crap for the same reason.

    Close your eyes and toggle the light switch on and off. Can you see the light? If so, there’s a whole lot more than one molecule.

    Human beings are bioluminescent.

    We glow so faintly that we can’t see each other in the dark but we can be picked up in the dark by sensitive enough equipment.

    You know what, since I get what you’re trying to say (even though you’re technically wrong) you can have my upvote.

    It’s amazing how many ways you’re wrong when you spend even a second thinking about it. Why don’t you go back in the shower and let this one simmer a bit more.

    1 molecule thick skin would be pretty see through. You need more than that to block out the light.

    Fortunately, vision is based on a “dark current” that requires energy to not see light. (This is supposedly why some people in a near-death experience report seeing a white tunnel effect.)

        It’s been that way since long before the dawn of humanity itself, and will be that way long after we ourselves are gone (unless all we leave behind are cockroaches), so don’t sweat it - our understanding is irrelevant to its continued functioning regardless:-).

    Put your hand in front of a strong light source and you’ll see red light through some of the skin at least.

A “Showerthought” is a simple term used to describe the thoughts that pop into your head while you’re doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

  • Both “200” and “160” are 2 minutes in microwave math
  • When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
  • More dreams have been destroyed by alarm clocks than anything else

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as “capitalism” and “communism”. If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy’s Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
