Fine tuning

Can gravitational waves help account for why there is more matter than antimatter?

“not an electric charge, but some sort of charge”? Okay… At least we are still in the world of hard science here. One thing: They had better trademark the name Q-ball. If their idea takes off, they will be glad they did. Go Q-balls! Read More ›

Sabine Hossenfelder asks, why do we think antimatter asymmetry is a problem?

Hossenfelder: "[O]nce you insist that the ratio was actually one, you have to come up with a mechanism for how it ended up not being one. And then you can publish papers with all kinds of complicated solutions to the problem which you just created. " Isn't she overlooking something? Read More ›

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: What if ET has morphed into what we now call the laws of nature?

Takehome: Scharf’s hypothesis highlights the genuine difficulty of accounting for a universe that comes into existence without any underlying intelligence at all. His thought experiment amounts to an intelligent design hypothesis for the universe in which the creators and the laws of nature turn out to be the same thing. It is much bolder than the usual arguments around fine-tuning of our universe. It highlights the genuine difficulty of accounting for a universe that comes into existence without any underlying intelligence at all. Read More ›

At Mind Matters News: Astronomer: We can’t just assume countless Earths out there

Marcelo Gleiser notes that the starting point of the Mediocrity Principle assumes countless Earths. That’s not a conclusion from evidence. It’s bad logic. Read More ›

At Mind Matters News: Physicist: If humans died out, the galaxy might lose all meaning

Brian Cox, host of The Universe, ended up becoming “more religious than I intended” when he reflected on why we care about the stars. Read More ›

At Mind Matters News: Theoretical physicist Sabine Hossenfelder: Colonizing Mars is a ridiculous idea!

The difficulties inherent in the idea of terraforming Mars are a good argument for the Privileged Planet Hypothesis regarding Earth. Earth is indeed special. Read More ›

Sabine Hossenfelder: No way to tell if the universe was fine-tuned for us — Rob Sheldon partially agrees

Sheldon: Even though I agree with Sabine about the fine tuning argument, I disagree strongly with her about the significance of the design we see in the world. "It just is" is not an explanation. Read More ›

Physicist Marcelo Gleiser: Beauty in the universe is an “illusory consequence of our human mathematics”

So what, exactly, is this “false and illusory” view of our universe? Is this short essay another veiled “correct” assault on the fact of the fine-tuning of the universe for life? There seems to be a lot of that out there these days. Orthodox science is now in a deadly conflict with facts… There can only be one outcome. 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 ›
