Face in multiverse

Sabine Hossenfelder Asks, Is the Multiverse Science or Religion?

Or pseudoscience? The no-nonsense theoretical physicist reveals a gift for comedy as she tries to explain theories that place no constraints on what can happen

Some science controversies arise in disputes over findings. The current flap over the James Webb Space Telescope data, for one. Others sound like clashes over philosophy — claims about the multiverse (countless universes out there) are a good example. Theoretical physicist Sabine Hossenfelder takes on the multiverse in in her new book, Existential Physics: A Scientist’s Guide to Life’s Biggest Questions (2022). She also addresses the topic concisely — and wittily — in a short video and a blog post at Back(Re)Action. She looks at three popular multiverse models: Many Worlds, Eternal Inflation, and String Theory Landscape. Here’s her take on Eternal Inflation: We don’t know how our universe began and maybe we will never know. We just talked about…

Abstract fractal patterns and shapes. Beautiful abstract background. Сolored waves,spirals, lines and circles. Infinite universe.

Is Ours One of a Few Working Universes Among Countless Flops?

Is that probable? How would we know? Philosopher Stephen C. Meyer offers some suggestions

In this fourth and final portion of a talk at the Dallas Conference on Science and Faith (2021), philosopher Stephen C. Meyer takes on the claim that the fine-tuning of our universe for life can be explained by the multiverse, that is, “there are many other universes with different laws and concepts of physics and different initial conditions, different arrangements that matter in energy at the beginning of those universes. And there are enough such universes to make the improbable features of our universe probable on a mega cosmic scale.” Dr. Meyer is the author of The Return of the God Hypothesis (Harper One, 2021). (A sample of the book is here.) The first portion is here, the second here,…
