I have the impression his claim is that general relativity is not a correct description of gravity (thus dark matter), so his theory would be to general relativity what general relativity is to Newtonian physics. > To say that Einstein is wrong looks like a cliché in fashion, today. That is true for sure! I don't like it either, it's just looks as clickbait. Also reinforces the popular misunderstanding of science. The serious scientific stance is that all theories are probably incomplete... But the mainstream doesn't even grasp what a theory is, thus the silly "evolution is just a theory" type of arguments. > To me, > Einstein is still vindicated on both the macro and the micro, and I take his > 1927 remarks, and its EPR paper as indications that he got a better > understanding on QM than his contemporaries. When it comes to theoretical physics I am just an enthusiastic outside observer. Looking at it from the "outside", I can't help but feel that "dark matter" is an euphemism for "the current theory has been falsified by observation, but we have nothing better for now". > In the same issue, the article "Scientists Find Religion Triggers Same Area > of Brain as Sex, Drugs and Love" is funny, but a bit trivial, as the brain > zone excited are the one related to pleasure.

Right, neural correlates are useful and interesting, but people read WAY too much into them...
