From Denyse O’Leary at Evolution News & Views:
For many people today, post-modern science is more of a quest to express an identity as believer in science, irrespective of evidence. Cosmologist Paul Steinhardt got a sense of this in 2014, when he reported that some proponents of early rapid cosmic inflation “already insist that the theory is equally valid whether or not gravitational waves are detected.” It fulfilled their needs. In 2017, cosmologist George Ellis, long a foe of post-modern cosmology, summed it up: “Scientific theories have since the seventeenth century been held tight by an experimental leash. In the last twenty years or so, both string theory and theories of the multiverse have slipped the leash.”
We have so much more data now. But it provides no evidence for a multiverse. That’s nothing unusual historically (think phlogiston and ether for great ideas that did not work). We used to just adjust. But today, increasing numbers of science-minded people demand a post-modern science that adapts to their needs. After all, we evolved to survive and pass on our genes, not to understand reality.
As a result, many cosmologists and science writers speak as if the multiverse merely awaits routine administrative clearance to morph into textbook science, absent evidence. Characteristically, they see themselves as fighting a conservative (fuddy-duddy) establishment which clings to a role for mere evidence.
