  • Honestly no, and that’s okay?

    Early web2 websites like MySpace did become “popular”. But IMO one of its layckings was trying out web2 by evolving something from web1’s static websites.

    Where Facebook is the platform that popularized web2 in a way that worked with what web2 was and fundamentally build something new off of that.

    I think Lemmy/mastatdon/most current federated clones that exist today won’t last all that long. Something that is built with federation to its core and instead of just being a feature, is central to its offering.

    What is that? Not a god damn clue.

    But I’m excited to try it out.

  • You are correct that the raisins would have other constraints to keep it from infitatly expanding into nothing. Not because it’s not expanding but because it has external constraints like gravity keeping it there.

    They do have expansion applied to them, but gravity and other things effecting space time would be keeping it on place.

    As for attoms, I think you picture something solid. But there’s not. The electrons are getting further from the nucleas, but it’s still bound quantum mechanically to the attoms regardless of its position.

    But then the nucleas isn’t soldi either. It’s made of smaller things yet, and so on and so forth. So inside would also be expanding. But again other forces at play would bind things together.

    The expansion is also not a force. It can’t overcome other forces so it keeps things in line.

    So it does happen on a small local scale though. It happens on ALL scales.

    But everything is expanding from everything. Meaning the observer is always centred of the expansion. This is because volume is constant. The rasins themselves do expand, but locally it’s such a small scale (10^-23 m/s for our solar system).

    This also works for how we understand the change in density. Volume is constant, but we’ve gone from infinitely dense to almost nothing.

    I think the trouble is also partly based around thinking of then universe as a volume, which implies a centre. And that’s where this analogy falls apart.

    Because everything is expanding from everything, there is no centre. YOU are always centre. So you are “expanding” but you don’t change volume.

    This is why I keep saying space isn’t getting bigger, distance is.

    It’s not that a sheet of paper becoming bigger so the grid paper becomes larger,. It’s changing it’s distance of something, not it’s size and shape.

    We don’t observe galaxies getting bigger. We observe them constantly moving away from us. Even. When they’re moving to us, but it’s done at a slower pace than expected. The further away you are, the faster you move away. And it’s a universal constant of 73km/s/Mpsc.

    Notice that is a speed per distance. It’s not saying space is getting bigger, it’s saying things are moving faster away from you the further you go away.

    The universe isn’t expanding like a loaf of bread because it has a volume. It’s expanding from one volume to another. Where the universe doesn’t.
