Knight: The multiverse is not pure nonsense, it is theoretically possible.But even if there were a multiverse, the generator that makes the universes itself would require fine-tuning, so the multiverse doesn’t get rid of the problem. And, as Lightman indicates, we have no independent experimental evidence for the existence of the multiverse in any case.

Multiverse physicist Max Tegmark switches gears; seeks AI to combat “news bias”
Readers may recall him from the four levels of multiverse he advocated in Scientific American in 2003. But forget that. He now thinks there is too much bias in American media and he is working on an AI program to combat it
The Principal Research Scientist at Georgia Tech explains why he does not believe in a multiverse
He recommends Bohmian mechanics, saying that it “accurately extends and reinterprets Bohr’s original ideas of complementarity, putting them on a more solid mathematical footing”.
Robert J. Marks on why there cannot be an infinite number of universes
The Big Bang Theory sitcom’s Sheldon Cooper insists that in no universe would he dance with Penny. That mighrt be true, says Marks but there still isn’t an infinite number of universes: But, some claim, there is an infinite number of universes in the multiverse. That is ludicrous because there are no infinities in the Read More…
At Forbes: Is there now evidence for a parallel universe?
Some scientists are claiming so, based on an odd finding from Antarctica. Ethan Siegel isn’t isn’t taking the bait.
Trinity Radio on cosmologist Sean Carroll and ignoring reality
But doesn’t a multiverse cosmologist like Sean Carroll get to pick and choose the reality he prefers from an infinite variety? Who says there is only one reality, the one he doesn’t like?
Another sally against the Big Bang
Look at it like this: If the multiverse prevails instead, science can be opened up to a vast variety of viewpoints and interests. Because facts really won’t matter any more.
Listen to Mother Nature Network convince itself that parallel worlds exist
Nope. Not a chance the proposed evidence will matter. The parallel universe folk probably don’t like our universe because it shows massive evidence of fine-tuning and that implies an intelligent origin. Any alternative theory will always be popular, irrespective of evidence.
At Scientific American: Another whoop for the multiverse
All the Cool people believe in it, which is just so much better than evidence.
Sabine Hossenfelder on why the Anthropic Principle is controversial
It’s controversial because it is sometimes used to support the idea of a multiverse. Otherwise, it should be common sense to assume that a venue in which we exist must feature conditions that allow for that. But the multiverse does not need logic, evidence, or science.
John Horgan on how multiverse theories are bad for science
The Scientific American columnist is unimpressed by two recent books on the subject, cosmologist Sean Carroll’s Something Deeply Hidden and science writer Tom Siegfried’s The Number of the Heavens.
Is the multiverse “increasingly popular” among physicists?
The multiverse makes physics so cool that it is indistinguishable from self-indulgence.
Rob Sheldon: The quantum effects shown in large molecules may make theories like the multiverse testable
Sheldon: “By measuring a hot stream of molecules with billions of states, this experiment may rule out CSL [Continuous Spontaneous Localization]. If so, it would be the first time an interpretation of QM was actually invalidated, suggesting we have entered a new era of testing theories of the foundations of QM.”
Multiverse is science based on zero evidence, science writer complains
Baggott, of course, also feels the need to take the ritual swipe at ID. He must do so because he is allowed to criticize crackpot cosmology provided that he holds to no thesis about the nature of nature that would impede its actual advance. He can regret it but he must not undermine it.
Sabine Hossenfelder explains the problem with the “many worlds” hypothesis
Hossenfelder: In the many worlds interpretation, if you set up a detector for a measurement, then the detector will also split into several universes.
