       | This all mind blowing. Can we make a guess of what the structure
       | of the universe is? Are there illustrations?

         | Yes, at the largest scales there are large structures composed
         | of galaxies with voids between them. At smaller scales, we can
         | observer large clusters of galaxies.

         | Really cool stuff!

         | Yes, awesome. I used to use that when teaching cosmology.

         | This is fantastic, it's much more comprehensible than the
         | Hopkins map.

       | and in what direction.

         | You can see how fast they're moving away from us by their
         | colour.
         | 
         | As for how fast they're moving sideways, nobody knows! But it's
         | slow compared to how fast they're moving away from us. (Except
         | for a very very small number of galaxies close to us.)

       | From the video it feels like they are selling this poster, and it
       | is pretty cool so fair enough. It reminds me of when I tried to
       | sell a physics poster to celebrate the first anniversary of the
       | gravitational waves discovery. Here was my fundraiser +
       | emotional/inspirational poster video:
       | https://www.indiegogo.com/projects/the-gravitational-waves-a...
       | to see the video). I personally ended up down a few hundred
       | pounds, but it was a fun experience and we raised a bit of money
       | for charity. (Many posters still left in my cupboard, so please
       | get in touch if you're interested - email in profile.)
