  • 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.

















  • It can be two things. Most people citing molon labe online like this have a desire to use their guns in self-righteous justification. This guy already has, got away with it, and was celebrated by terrible people. He also got on the outs with the same crowd that loved him by saying he wouldn’t vote for Trump over his gun rights record(then quickly tried to take it back when Maga went against him).

    He wants his adoring fans back, perhaps not realizing they didn’t like him, they just like that he got away with fulfilling a fantasy many of them have: killing people they hate.
