How much do you know about general relativity? (This is a honest question BTW -- I know the postulates behind it and some of the maths, but I've never studied its implications in detail, besides the Schwarzschild metric and the FLRW metric, so I have trouble telling the levels above mine apart.)
I will pass the discussion about this here, I hope you understand that.
But please, fell free to engage me there, on my blog.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
