The Observable Universe Just Got a Bit Smaller
Paul Halpern

Dear authors, thanks a lot for this article; yet, as we talk physics and measurement here, we should talk also the uncertainties: 45.66 vs. 45.34 is 0.7% difference: so what is the precision of the previous and current calculation? Aren’t they actually compatible? If yes, then this is not much of a news, only a confirmation of compatibility of old and new data, while it does serve the good opportunity to inform science enthusiasts on what is the horizon etc. Also, the link does not lead to your article, do you have an arXiv version? Thank you a lot, Jiri Kvita
