Michael Egnor on why the multiverse is just a way of evading reality

Michael Egnor: The fact that the universe is tuned — that is, the fact there is any consistency at all in the laws of physics — demonstrates God’s existence. This is Aquinas’ Fifth Way, which is the proof from design. Read More ›

Michael Egnor on why we don’t live in a multiverse

Egnor: The problem is, to make their claim credible, [Novella and Goff] must show that there actually are localities in the universe in which the laws of physics differ in a way that would make fine tuning likely by chance. Read More ›

Peter Woit, whom we sometimes follow because he is fun, looks back on string theory

He doesn’t seem to get the fact that string theory was a religious movement that was bound to end badly. The most distressing victim is science. But then that was well before the war on math, wasn’t it? Read More ›

At Quanta: Are we looking at the end of physics?

Ah yes, the problem of dead-endedness that Sabine Hossenfelder often writes about. As does Columbia mathematician Peter Woit, on the subject of string theory. But surely much of the nonsense around string theory and the multiverse is in part due to a practical failure—the inability to find even a single particle of dark matter or similar evidence for dark energy.

Wintery Knight: Does the multiverse counter the fine-tuning argument for God’s existence?

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. Read More ›

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 Read More ›

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 physical world. Even if there were, Cantor’s theory of the infinite shows that, if there were an infinite number of contingencies, not all contingency combinations could be accounted for by an infinite number of universes. Therefore, even if there is an infinite number of universes with an infinite number of contingencies, then—among an infinite number of Sheldons—it’s possible that none of the Sheldons dance.

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? Read More ›
