The results aren&amp;#x27;t actually that interesting. The posterior on H0 (the rate that the universe is expanding) is not at all competitive with the current best methods. They get 67 +/- 6 whereas things like Planck have error bars on the order of 1. Checkout their figure 5 to see the different error bars. That is not to say the paper is bad at all! The method they use is pretty cool and not common (at least I haven&amp;#x27;t seen it used before, though they do mention there have been people looking at this for a while). Also, as the…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1903.12097/"&gt;Paper and discussion history&lt;/a&gt;.
