A recent question Are Stephen Crothers' claims legitimate? has made me very uneasy. I will explain why:
First of all, this question is too open ended. I visited Crothers' website, looked through a lot of the papers and correspondence (mostly for my amusement) and discovered that he has a LONG list of arguments against the existence of Black Holes, the Big Bang and tonnes of other mainstream ideas in astrophysics and cosmology. I saw the first video the OP linked too and there were many claims made there too.
It seems the OP desires a simple explanation. This is almost impossible without going into technicalities of the Schwarzschild solution and other concepts in GTR, owing to the nature of Crothers' arguments. One can just look through the exchanges Crothers' had with many scientists, some of whom took great effort to dissect counter his arguments, to see how time-consuming this will be.
Beginners looking at this question will see: i) Videos and papers of a man putting forth his 'bold' arguments. ii) No answer technically detailed enough to dissect all the claims given in the links. This will give beginners the impression that Crothers' has a legitimate claim to make in completely dismissing and trashing the foundations of black holes and cosmology. This could potentially mislead beginners.
SE is ranked high in Google searches. This will create more publicity for Crothers' and Co.
I tried flagging the question. Manish told me that he would appreciate a discussion on this topic before deciding what to do with it.
Also I have nothing against Crothers' and Co. personally and it is only after reading his emails exchange, papers and watching his videos have I come to realize the true danger of giving too much attention to people like him (who are totally closed-minded). I only hope my question on Meta doesn't publicize him further. If it does, I will probably delete it.
