The Milky Way Halo

  It would be interesting to see the same post in 20 billion years if cosmic expansion continues.

    Metric expansion only has an effect on structures larger than galaxies, so there should be no difference in 20by as a result of it. Eventually if it continues distant galaxies will redshift to black, but the Milky Way itself won’t be torn apart.

    In 20B years, HN users would be seeing this in their mind's eye !

    We'll be to busy preparing for the next big thing, in 20 billion years VR will be just a couple of years away.

  I'd love to see also a mouse-rotatable 3D model of this.
