          • Question #1: Dark Matter Debunked?

              • it’s the second message I’m sending you tonight, so sorry for the spamming, but I believe this article is quite juicy: https://link.springer.com/article/10.1140/epjc/s10052-021-08967-3 Basically the author is claiming to have debunked dark matter (!!) by factoring in general relativity to calculate the rotation curve of galaxies – something apparently no one has bothered doing before? (!!) Anyway, it seems to me very unlikely that a lone researcher can run some calculations and suddenly debunk I don’t know how many decades of dark matter theories. Maybe something interesting to talk about during the show. I promise I won’t send you any other messages for at least a couple of galactic years. Take care and thanks for your awesome work Cheers, Max

            Skeptical Quote of the Week

            ‘How weak our brains are, and how quickly they are terrified and led into error by a small incomprehensible fact. Instead of saying simply: ‘I do not understand because I do not know the cause,’ we immediately imagine terrible mysteries and supernatural powers.’ - Guy De Maupassant
