But the dream can’t be allowed to die.
For about as long as I can remember, string theorists and multiverse fans have been pointing to Planck data as the test of their ideas. For cosmic strings, the last Planck data release had a paper ruling them out. I don’t see a paper on this topic out or projected for the new data, it seems that this is now something not even worth looking for.
We’ve also been hearing for years that Planck will test supposed evidence of bubble collisions indicating other universes, see for instance this article about this paper, where the article states that
Data from the Planck telescope should resolve the question once and for all.
I don’t see anything in the new data even looking for this. Has it already been ruled out, without any publicity, or did the Planck people think it was something not worth even looking for?
And check out the comments too, for example, despite the negative findings, the BBC report was
… “Multiverse, multiverse, multiverse.”
The multiverse is a classic in a problem we’ve noted before: In a culture dominated by naturalism, the cultural needs of naturalism submerge science as traditionally understood.
The fact that there is no evidence for the multiverse means far less than a science or math rigorist might hope. The goal becomes not assessing the evidence but producing what looks like evidence—or, when all else fails, continuing to promise to provide evidence.
