  • They’re talking about time dilation.

    Objects with no mass traveling at light speed in a vacuum don’t experience time.

    A photon, traveling through a vacuum for forty years, from its perspective, leaves the instant it arrives.

    Likewise, if you can travel at the speed of light for forty years and came back to earth, your twin would age forty years and you wouldn’t age at all.

    At a much smaller scale we have to use time dilation to keep clocks in space running at the same time as clocks on Earth. Because in geosynchronous orbit they are traveling faster than objects on the ground.











  • Yeah, I think self awareness is a really low bar that we tend to think we’re special for having. And that this fallacy is part of why animal rights are basically shit.

    The mirror test does show that an animal is self-conscious, in the sense that, it likely cares what others think and thus has a theory of mind. And you’re right, it only proves self-consciousness, it doesn’t prove its lack because as I stated earlier in the case of my rats, other senses might be involved that would produce that response.

    Dogs too. Seem much more concerned with how each other smell than how each other look.



  • As a person with trauma, who has had trauma all his life, I find social interactions draining and stressful. I have trouble developing trust, which makes it difficult to bond with others. And which makes me more lonely in a crowded room than I feel right now sharing my thoughts with you all on the internet.

    I guess I’m curious how this study would fair if it was done on self-described introverts. I value my friends, but maintaining and developing those relationships is a burden rather than a joy for me.


  • Did you read the article or just kneejerk at the title? Sleeping in separate beds increases the risks of SIDs, for example. It is weird that western parents continue doing this to ‘instill individualism’ when it literally kills our children and slows down parent/child bonding in primates. Shit, we still circumcise most male babies because the Korn Flakes guy thought it was dirty for boys to touch themselves. We are weird!

    If you prefer to feel ashamed rather than learning something when you encounter new information because of a clickbait article title, well, I can’t stop you. Or even blame you.

    But the shameful part isn’t doing something weird out of ignorance, but continuing once we have better information. Putting our pride ahead of our children. That would be a shame.





  • Even clean rooms don’t stay clean because great apes are not clean, and they have to work in the space. So even the best spaces aren’t fool proof which is why lab teks wear masks and other equipment.

    But yeah, work well enough to keep kids etc from being sick, would require lab level air filtration to make a difference. And we’d probably still have to dress the kids up like lab nerds even with lab level filters and fans.


  • Even a cheap HEPA filter is good enough to filter COVID.

    But, all contaminated air has to actually go through the filter.

    This means you need to do several full air exchanges in the required space per hour really if you want to keep people from getting sick. Like a laboratory clean room would do.

    And setting up that level of HEPA filtration, is fucking expensive.

    I built a very small flowhood for mycology. The filter was $200. The fan another $80. And I’m only keeping a one x two space clean. I imagine it’s just not economical to really apply this technology to schools etc at this point in time.
