Having noticed that 85 KPH is slower than 85 MPH, it took me a while to work out that 85 MPH is much slower than 68 km/s (and I was blindly assuming that the universe is at least one megaparsec in radius), after which the title-text joke started making sense. Congratulations on being almost too subtle for me.00:46, 16 September 2021 (UTC)

Is the 85 mph number significant in any way? Why does "Dave" who points radar guns in random directions get this number? 108.162.245.167 03:41, 16 September 2021 (UTC) Well, it's probably over the speed limit in most places. Maybe Dave is a traffic cop? --172.68.129.137 04:55, 16 September 2021 (UTC)

Unfortunately, the explanation only explains the things everyone can read on the internet anyway. 85 mph or 85 km/h have the wrong unit, because for the expansion speed we need to look at two points of space, measure how fast they move away from each other. Obviously this should be a number that increases linearly with the distance of the two points (if space is created equally everywhere in the universe). Thus the 85 km/h misses the length. Is the joke here that a random dudes results are reported equally (false equivalence)? --162.158.93.142 04:41, 16 September 2021 (UTC)

Dave again: "But when they hit 88 mph, we're gonna see some REALLY weird shit!" RAGBRAIvet (talk) 06:50, 16 September 2021 (UTC)

Just a thought: maybe Dave is talking about Fords Galaxies? -- 162.158.183.222 08:39, 16 September 2021 (UTC)
