Potential issues?

[edit]

Hi, this looks like a clusterfuck, so someone with actual physics knowledge please cross-check ...

Text: "The combined dimensions of the walls are __115 km/s Mpc__ on the major dimensions and __90 km/s Mpc__ on the minor ones, which corresponds to about __385 million__ and __300 million__ light years"

Sidebar:

  • Major axis: __115 Mpc (375 Mly)__ h−1 ~0.676 (Hubble constant based on 2016 Planck data)
  • Minor axis: __115 Mpc (375 Mly)__ h−1 ~0.676 (Hubble constant based on 2016 Planck data)

There are (at least) three seeming inconsistencies in these two chunks of information:

  • First, "km/s Mpc" does not seem like a valid unit to me. Pretty sure it should only be Mpc
  • The conversion to light years is different between the text and the sidebar (one claiming 115Mpc are 385, the other claiming it's 375 million light years)
  • The minor axis in the sidebar does not match the "minor dimensions" in the text (115Mpc vs 90Mpc).
