  • 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.

    Disclaimer: not a historian. Born in the early 90s so a lot of my judgement above is bassed off of foggy memories and are my opinions and only opions.

    I see the common mistake of associating the left with authoritarianism.

    China and such are not left. They’re even further right to the point of fascism labeled communism.

    Remebere communism/socialism is about the workers relation to the means of production. Chinese people do not own the factories they work on, so I’m not sure you can call them left.



  • 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.

    The answer is there’s no such thing as absolute distance. Because there’s no such thing as absolute position. Quantum garuntees inaccuracies in position.

    And your right. We can’t actually measure the expansion of the universe directly. It’s actually because of the red shift we do.

    The reason we can see the red shift is because the universe holds the speed of light in a vacuum constant.

    So if the universe is expanding, and the speed of light is expanding with it, in-order for the speed of light to stay the same, it has to travel more distance in a time. Meaning it’s stretching it’s wavelength as it moves. Just like something moving away from us does. IIRC it’s because of observations that everything is constantly moving further from us, the further out you go, the faster it’s moving away.

    But everything is moving from everything, including itself.

    I do apologize if I’m a little muddy, I did my physics degree about a decade ago.

    Edit as for why gravitational waves travel at the same as E&M waves is because “information” is what travels at the speed of light. For an electro magnetic wave that’s disturbances in E&M. For gravity that’s ripples in the fabric of space-time. For quantum there’s experiments showing that entangled particles will collapse together, if sperated by distance, the lag time is also the speed of light.

    EDIT 2:

    The only thing faster than the speed of light, is actually the expansion of the universe beyond a certain distance. Don’t remember what it is. But because distance istself is expanding, that’s proportional to distance. So the expansion rate is actually faster than the speed of light far enough out. But no SINGLE point is expanding faster than the speed of light.

    We can still measure the red/blue shift to find the star, but if you don’t correct for it, it will be wrong.

    Also I don’t know enough about gravitational waves wo know how it would be effected by the expansion of the universe.

    But remember when LIGO measures, it’s not measuring absolute values that we would see drift in. It’s all relative measurements from a short time period prior. It would follow in lockstep with the expansion.

    Also gravitational waves arent particles. They’re disturbances in the fabric of the universe. So they don’t behave like standard waves do. They have their own wave mechanics that I haven’t studied.

    And light is having its wavelength stretched. Speed of is not proportional to frequency in a vacuum only the permittivity and permeability of free space. So it’s wavelength is getting expanded without

    But again. Space isn’t expanding. Distance is.

    Also that’s not how informeters work.

    They compare distance across two lines. They can only detect the differences between those lines. Because expansion is universal in all directions, it’s not detectable on informeters.
