::It is the idea that a paper seems to prove a theory wrong and then the press goes out presenting it like a proof instead of asking someone to explain to them why it doesn't fit the data. That is what this comic is about - not dark matter.

"What is the flip the table over reference in title text. To make other do the same through mirror neruons? Still new explanation. Add more if you can" "The title text also uses Mirror neurons as a reference to a joke: it suggests to "flip this table", just as a mirror flips the image in front of it." I too want to think there is a joke here about mirror behavior or something but I just don't get it. Somebody's got to come up with a clearer, and funnier, example![[User:ExternalMonolog|ExternalMonolog]] ([[User talk:ExternalMonolog|talk]]) 16:31, 11 November 2016 (UTC) | "What is the flip the table over reference in title text.

Seems like awkward timing since https://arxiv.org/abs/1611.02269 was posted 3 days ago, a non-MOND non-dark matter theory coming from Prof. Erik Verlinde, and this particular theory starts from first principles yet matches behavior of galaxies.

:But this was the same way that led us to discover Neptune, Uranus, Pluto, and the Kuiper belt.

Since the Bullet Cluster has been brought up again, it should be pointed out that it doesn't provide the iron-clad evidence for dark matter that some appear to think it does. Ask a MOND (or MOG)-sympathetic physicist about it and they'll direct you to [https://arxiv.org/abs/astro-ph/0702146 Brownstein & Moffat, 2007], which claims to provide a modified-gravity model that fits the data just as well (or perhaps even better) than λCDM (dark matter). I'm not going to pretend to be able to assess the model they present (or even really understand it), and I'm shamelessly parroting a recent blog-post and commentary by [https://backreaction.blogspot.co.uk/2016/10/modified-gravity-vs-particle-dark.html Sabine Hossenfelder] of the Frankfurt Institute of Advanced Study . But I think the idea that the controversy between λCDM and MOG has been settled is perhaps a distortion of the facts, and those who aren't intimately familiar with the field might be wise to avoid treating it as such.
