  • Not an expert, but my understanding is that the multiverse (at least, what we today associate as the multiverse) came about due to the many worlds interpretation of quantum mechanics. Basically, quantum physicists had an observation - particles were moving as though they were being pushed by an invisible wave, and they would pick a random position based on that wave when observed.

    The most prevalent explanation for this behavior is the Copenhagen interpretation, which states that the particle is the invisible wave, and the wave collapses into a particle when it is measured. But another common interpretation is the many worlds interpretation, which states that the invisible wave is just a statistical probability of where the particle is. And the reason why the particle seems to pick a random point on the wave when observed is actually because the particle creates branching timelines, and we can only observe what happens in our own timelines. Hence, it seems random to us.

    I speculate that the idea of multiple parallel timelines, each slightly different, was probably pretty popular with scifi writers, especially since it’s an easy way to portray “what if” scenarios in their stories, and so the concept became popular because of that

  • Former child in a bilingual household. The time that your child spends outside of your home has by far the biggest influence on language fluency. You can have your child speak a language at home, and they would be able to understand it and speak it, but it would be limited - likely conversationally fluent, but not natively fluent.

    If you can find a community for that language and culture that you visit every once a week, it will help reinforce that language. There might be language schools run by people from that culture - it’ll be an easy way to get in touch with other people from that same culture

  • My understanding is that there is always color variation because they don’t color their sauces with food coloring, and as a result, the sauces made at the beginning of harvest season will have a different color than the sauces made at the end of harvest season.

    But also they no longer use the same chili due to greed, so that may not apply anymore

  • Yeah, sure! This happens to be my field of research.

    So I was referring to this particular paper, which unfortunately (to my knowledge) didn’t get much follow-up.

    Tangentially, there is much other evidence that circadian rhythms have evolved in part to deal with differences in microbial pathogens at the day vs. at night. However, whether it’s because the composition of bacteria in the atmosphere is different, or because animals are more likely to get themselves exposed to pathogens when they’re foraging, or a mix of both, is unclear. My favorite paper that demonstrates this effect is this one, where the circadian clock affects how strongly the immune system responds to bacteria in the lungs. I’ll also include the seminal paper here that first kickstarted the idea that immunology is fundamentally circadian, although frankly I didn’t like how the paper was written. It looked at how mice responded to Salmonella infection at the day vs. at night and found a difference in immune response that then led to a difference in how severe the infection got.

  • You’re right, I can’t give medical advice. But having abnormally long or short circadian days is a known thing - called circadian diseases. It’s not really my specialty, so I can’t comment too much on it, but my understanding is that many of them are genetic. These genetic variations can cause the circadian clock to run slower or faster than normal (which happens to be adjacent to what I study, so I can talk about it in excruciating detail if desired)

    The Familial Advanced Sleep Phase Syndrome (FASP) is one such genetic circadian disease that gets a lot of attention among the circadian field, but you almost certainly don’t have it, since FASP makes your clock run shorter than 24 hours, whereas you seem to imply that yours runs longer.

    The key thing to remember is that the circadian clock is not psychological. There is an actual, physical, molecular clock running in your brain and in nearly all the cells in your body. If this clock has imperfections, then that will directly lead to consequences in your circadian rhythms and your sleep cycle. The circadian clock is a real thing that people with the right equipment can measure and read. It wouldn’t even be particularly hard - just a blood sample or a swab would be sufficient. To be honest, I myself would like to study your cells to see if there really is anything out of place, but that would probably break so many research and ethics rules.

    Anyways, to answer your question, I would recommend getting a medical opinion - it might be worth specifically bringing up that you suspect you have a circadian disease. I’m not too sure about treatment options, since my impression has generally been that we kind of don’t have any treatments for circadian diseases. But it’s not really my specialty, so maybe there is. My memory is that melatonin is a masking cue, which basically means that it makes you sleep but it doesn’t actually affect your circadian clock (which probably explains your poor experience with melatonin).

  • I’m pretty sure that’s the general hypothesis in the field, but as you might imagine, it’ll be very difficult to prove. There was a study done sometime (I don’t fully remember when) where researchers collected data on when people go to sleep and when they wake up, and they found that there was a remarkably normal distribution in the population for when people wake up and sleep.

    My personal interpretation is that chronotypes (what you call early birds and night owls) are genetic in some way, but I don’t specialize in this area, so don’t take my word for it
