  • A lot of the suppositions are done with impossible to happen stuff, like the sun literally disappearing, or collapsing into a blackhole with no added mass (a sun mass blackhole would be stable, but I don’t know how one could be created).

    If it disappeared, then we’d still feel even gravity for those 8 mins, as the effect of gravity propagated at the speed of light. If it somehow magically became a black hole, we’d still orbit it the same even after 8 mins, but losing all the head would eventually kill us.

    The expected explosion wouldn’t be what makes the earth uninhabitable either. The sun increases in luminosity by ~1% every 100 million years, and it’s estimated that between 700 million and 1.5 billion years the surface of the planet will be too hot for liquid water. An astronomer also says photosynthesis would be impossible in 500-600 million years.


  • Yes, and some animals (mostly birds iirc) do see UV. Boring brown/black birds aren’t so boring in UV. I don’t know the evolutionary pressure necessary for UV, but it could have developed. Red, for instance, is believed to have been useful for us to pick out berries. Wolves, being carnivorous, wouldn’t necessarily need it, so see in yellow blue… or so I read as a theory a while ago.

    Studies generally take time, so if it were months later they likely had it before you. The years later is a maybe, but also possible because it takes time to get grants to do studies as well. Exceptions tend to be more urgent stuff like the pandemic, but even then we had SARS outbreaks decades ago and they’ve been studying it for a while, even if it wasn’t specific SARS-COV-2.











  • Your original comment could be taken in various tones and they wanted a clarification. For what it’s worth, it is useful to some to hear it, since it could help people see differences between the US and other countries. It’s just said in a way that felt more like “Butchers don’t do this” rather than “As the contrast, I don’t see this done in my country”. Either way though, in the spirit of the question it is sorta off topic.

    It’s like asking “Why does this currency have this person on it?” and getting the answer “I’ve never seen that currency used anywhere I lived.” While true, it’s not really relevant, doesn’t answer the question, and can either be taken as a long winded way to say “I don’t know” or stubborn self centered everything worth knowing is centered around your own experiences. Which is definitely reading into it too much, but there are people who act like that, either as trolls or real jingoists.

    Not that I’m gonna claim the Bible is consistent, bu5 Ecc 9:5 basically say the dead are aware of nothing. People who believe often argue this one is a metaphor instead of the ones about Eternal punishment.

    I grew up JW myself, but they believe dead is dead, and don’t believe in eternal torment. They do still believe in heaven and in eternal life, to come at a different time, so it’s not like they don’t believe the fantasy stuff as well, they just agree with no eternal torment.

    I mostly don’t ever answer calls I don’t recognize, and even the ones I do I don’t often answer if I’m at work etc. I’ve only answered calls when it’s for something important being delivered, fixed, or scheduled (recent examples in same order: TV, Internet, renting a place(less recent, but all I could think of)).
