Comment on I hate this image because idiots will see it, not understand what its showing, and make up some crazy shit based on it.

  First thing I will point out is there is no known shape of the univers.

    If we assume the hubble constant is the same in all directions, the farthest we’d be able to see would be a sphere, dictated by the time light has had to travel to us.

      That’s what I’m assuming the original diagram is showing, the “Observable Universe” in some sort of radically increasing scale.

        It’d be interesting to see what a log scale would look like for this. I’ll see if I can find one.

        Here’s one.

        Looks like the image at the top is a bit condensed comparatively.

      I’ll admit, I’m not deep in astronomy but thats inherently misguided. In a 3d space, observing at a fixed point, all areas that extend past how far we can observe would not be the shape of the universe but just our range of vision.

        Thus the term “observable universe”. Everything beyond our observable universe is being expanded away from us at faster than the speed of light, so nothing outside will ever reach us. Causality is completely and irrevocably severed at those distances so, arguably, anything outside the observable universe is not part of “our” universe.

    Is saddle still the best candidate? Like when you move a circle across a circle you get a torus, and when you move a parabola across parabola you get a “saddle”

      I want a toroidal universe. Just so it can be eaten by an extracosmic Homer Simpson.

    obviously the eye of our universe is flat

  It’s not really to scale at all. Look at the distance between earth and the moon in relation to the other planets.
