  • Edit: This person deleted their comments, so to clarify, it’s an answer to something along these lines: “You need evidence? Did you look at the post?”

    I did. And there is exactly zero verifiable evidence. Are there any verified photos? Material or biological analyses? Spectrography graphs? For now, there is none.

    At this point it’s still just “one dude heard that another dude says it’s totally true”. Once something goes public, we can discuss it. But for now, nothing can be seriously discussed, it’s all speculation.

    Hell, I would love for it to be aliens. But up to this point in our collective history, it’s never aliens.




  • Can any headline that ends in a question mark be answered by the word no?
    No.

    Here’s a quote from that wiki page you linked to:

    A 2018 study of 2,585 articles in four academic journals in the field of ecology similarly found that very few titles were posed as questions at all, with 1.82 percent being wh-questions and 2.15 percent being yes/no questions. Of the yes/no questions, 44 percent were answered “yes”, 34 percent “maybe”, and only 22 percent were answered “no”.

    In 2015, a study of 26,000 articles from 13 news sites on the World Wide Web, conducted by a data scientist and published on his blog, found that the majority (54 percent) were yes/no questions, which divided into 20 percent “yes” answers, 17 percent “no” answers and 16 percent whose answers he could not determine.



  • Sustained human pedal-powered energy output is about 500W for world-class cyclists and around 100–200W for average people. Your body also produces ~100W of heat energy by simply existing, and that can rise to about 500W when exercising.

    So the output range we’re looking at here is something like 300–1000Wh per hour depending on your fitness level and exercise intensity. 1 kWh costs ~10–30 cents around the world, I think.

    You’re gonna spend much more on extra food to fuel your pedalling than you’ll ever be able to save on heating bills :)






  • Wet bulb temperature is basically converting to 100% humidity equivalent, so as you get closer to 100%, WBT approaches measured temperature. We use this metric because our bodies cool mostly via evaporation, and no evaporation is possible at 100% — the air is already fully saturated. So in general, WBT means minimum possible temperature that can be reached by evaporative cooling. Once your body loses the ability to cool, it rushes to match surrounding wet bulb temperature (or even exceed it, since we produce about 100W of heat energy by simply existing).

    So 52C at 90% is about 50C WBT. Survivable for mere minutes for some, and probably for about an hour or so for most humans. Definitely not survivable for a full day.



  • Ok, so it doesn’t mention wet bulb temperature anywhere, so I went to figure it out. The first thing I was surprised with is apparently most of online calculators don’t take in values higher than 50C.

    I couldn’t find the exact data about humidity for that day, but it has been 35-40%+ at a minimum for most days in that region, sometimes even reaching 90%.

    So, 52C at around 40% humidity is 37.5C in wet bulb temp. The point of survivability is around 35, and most humans should be able to withstand 37.5 for several hours, but it’s much worse for sick or elderly. 39 is often a death sentence even for healthy humans after just two hours — your body can no longer lose heat and you bake from the inside. That’s like having an unstoppable runaway fever. And with that humidity it’s reached at 54C.

    We’re dangerously close to that.
