At Mind Matters News: Multiverse cosmology is not a good argument against God

God could have created countless universes on various principles for a variety of reasons. The key argument against the multiverse is that there is no evidence for it; it takes us outside the realm of observable science — a choice with consequences. Read More ›

At Mind Matters News: Why just anything can’t happen given an infinite sum of universes

Marks: It can be shown mathematically that the infinite does not exist in reality, only in our minds. Thus an infinite number of universes cannot exist. Read More ›

Ethan Siegel: The multiverse (and another you) are “all but inevitable”

Essentially, Siegel, the person who has Big Problems with something as widely accepted as the Big Bang, is quite prepared to accept all this far out stuff. That is where the naturalist project is just now. Read More ›

Molecular geneticist asks: “Does the existence of a multiverse hold the key for why nature’s laws seem so simple?”

Johnjoe McFadden's latest book is Life Is Simple (2021), in which he proposes that universes evolve in a Darwinian process, which “solves” the fine-tuning “problem”. One difference that we might note between this thesis and the sort of thing we read in biology journals is that there is evidence for the existence of countless life forms, whether or not their journey through time is explained by Darwinism. There is no evidence of any universe other than our own. Read More ›

Sabine Hossenfelder’s op-ed not published at APS?

This is the kind of thing she said: What about Avi Loeb’s claim that the interstellar object `Oumuamua was alien technology? Loeb has justified his speculation by pointing towards scientists who ponder multiverses and extra dimensions. He seems to think his argument is similar. But Loeb’s argument isn’t degenerative science. It's just bad science. He jumped to conclusions from incomplete data. Read More ›

What kind of faith does it take to believe in a multiverse?

Brian Keating: The concept of the Multiverse is an old one, one that has been approached primarily as a matter of metaphysics or philosophy. But is it scientific? And, if it is scientific, why do so many of its most ardent supporters describe their 'faith' in the Multiverse? Read More ›

Science writer John Horgan on why the multiverse is a fantasy

Horgan: First, science is in a slump, for reasons both internal and external. Science is ill-served when prominent thinkers tout ideas that can never be tested and hence are, sorry, unscientific. Moreover, at a time when our world, the real world, faces serious problems, dwelling on multiverses strikes me as escapism—akin to billionaires fantasizing about colonizing Mars. Read More ›

Science writer critiques the “many worlds” (multiverse) fantasy; Rob Sheldon weighs in

But the multiverse isn’t really about evidence or falsifiability. The theory is held in defiance of the demand for evidence and believed in such a way as to make falsifiability sound unCool. As Ball perceptively notes, “Even though most physicists dismiss or even deride it, it is often eagerly embraced by physics popularizers and their audiences.” Perhaps it is best described as a lifestyle choice.

Fine tuning of the universe: The strong force and the fine structure constant

Luke Barnes: What would happen in a hypothetical universe in which the fundamental constants of nature had other values? There is nothing mathematically wrong with these hypothetical universes. But there is one thing that they almost always lack — life. Read More ›

Another evidence-free whoop for the multiverse

Let’s be clear here. We have evidence for fine-tuning in the only universe we know to exist. To argue against it, we must posit universes for which we have no evidence and maybe cannot ever have any evidence. This makes sense, WHY again? Isn't it all becoming a bit of a scandal? Read More ›

At The Conversation: Can the laws of physics disprove God?

This seems to be a rather light piece intellectually but it gives some sense of what the wine bar would be saying about God and science if COVID-19 crazy hadn’t put it out of business: "But God isn’t a valid scientific explanation. The theory of the multiverse, instead, solves the mystery because it allows different universes to have different physical laws. So it’s not surprising that we should happen to see ourselves in one of the few universes that could support life. Of course, you can’t disprove the idea that a God may have created the multiverse."
