  • They are being illegally logged and I’m super pissed about it, I grew up in them. The postcards are part of a campaign to help save them by writing to the state minister for the environment, I’ve been finding it hard to do because it’s such an emotional thing for me…









  • No, that’s not the case at all.

    If you fall into a black hole, you can do no experiment to detect the horizon, it’s a completely unremarkable region of space to you. Infinite gravity is only really a thing at the singularity, but that’s almost definitely just because our theoretical models breakdown and stop giving accurate descriptions of reality there.

    The stretching is just because of tidal forces, which means that gravity gets so much stronger closer to the black hole that your feet are pulled harder than your head, you experience the same thing standing on earth, it’s just that the change in gravity is basically negligible here.

    I like to think of it as a big list of extremely complicated instructions that you can follow to see how different types of particles interact in the standard model.

    There’s a lot of different phenomena that you can derive from it, but my favourite is that if you know what you’re doing, you can just read possible interactions off of it.

    It’s also unnecessarily complicated, I’ve never seen someone have to use the full thing, you can get rid of a lot of it when you only care about specific particles. Part of the complication is that it’s some insanely dense notation, it’s actually far larger than it appears and contains lots of really complicated mathematical objects with some wild properties.

    (And to the pendants, yes this is an equation for quantum fields and not particles exactly, but that’s never easy to explain)
