We consider it almost obvious today.

First, I am not sure that is correct, but I am not much of a historian. Maybe more importantly, this isn't the point. The two cases are empirically and theoretically entirely different.

But I also read that this was the exact same reaction that Einstein received for his two theories on relativity. This widely shared opinion was reportedly the reason that he did not get his Nobel Price for his most important work.

It's basically impossible at this point to get something new going, not if you're not already famous. I see a lot of young people leave for this reason. Very strong rich-get-richer pipe. Though at least in Germany we still have a side-population by people who were tenured before that. Most of them now near retirement though. <Sabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-64368580120389484192018-04-04T00:57:08.398-04:002018-04-04T00:57:08.398-04:00Jim's book is excellent, a good read whether y...Jim's book is excellent, a good read whether you agree with him or not. tyyhttps://www.blogger.com/profile/05296030725193206870noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-30476395610033532842018-04-04T00:51:33.424-04:002018-04-04T00:51:33.424-04:00Michael,
