The Importance of Reassessment in Quantum Gravity

At a naive level, it looks like a universe which is exactly the one that the inflationary theorist told us about. But this situation leaves a conundrum because we have nothing that confirms anything which goes beyond these models. We've been expecting for about a decade to see signals of quantum space time. And these are not there either so far. So my impression is that when very smart people have been working under certain assumptions for a long time, and these ideas have been around for a lot longer than Feynman was. It's time to reassess the foundations of our thinking. Doesn't mean that everybody should do that, but some people should do that. I find myself doing some of
