Physicist: Science, by Nature, Can’t Have a Theory of Everything

Such a theory is a sort of religious quest that has united philosophers, theologians, and scientists, But is it possible?

With admirable clarity, astronomer and physicist Marcelo Gleiser explains what a Theory of Everything is and is not: It’s not about every detail of life that happens to us. It’s the search for a single, underlying force that unites the four fundamental forces of nature — gravity, electromagnetism, the strong nuclear force, and the weak nuclear force — into one single underlying force. Why haven’t we found it? Well, first, he says, “We do not see this unity because it is only manifest at extremely high energies, well beyond what we can perceive even with our most powerful machines.” But second — and more significantly — there is a real question, Gleiser contends, whether science is by nature suited to…

Why Did Stephen Hawking Give Up on a Theory of Everything?

Daniel Díaz and Ola Hössjer continue their discussion of the fine tuning of the universal constants of nature with Robert J. Marks

In a continuing conversation with Swedish mathematician Ola Hössjer and Colombian biostatistician Daniel Díaz on the fine-tuning of the universe — and Earth — for life, Walter Bradley Center director Robert J. Marks asks them about why a Theory of Everything eludes us and about the life-permitting interval — the narrow window for life that the constants of the universe permit. This is the second part of Episode 3, “The universe is so fine-tuned!” (September 16, 2021). Earlier portions, with transcripts and notes, are listed below. https://episodes.castos.com/mindmatters/Mind-Matters-Episode-152-Hossjer-Diaz.mp3 This portion begins at 12:36 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks: In truth, there’s a lot of fundamental constants — the electric charge of an electron,…


How Materialism Proves Unbounded Scientific Ignorance

There is an infinite number of things that are true that we cannot prove scientifically and never will

Science is based on a glut of laws from physics, chemistry, mathematics, and other areas. The assumption of scientific materialism, as I understand it, is that science has explained or will explain everything. The final conclusion of scientific materialism, also known as scientism, is nicely captured in a question chemist Peter Atkins asked philosopher William Lane Craig in a debate: “Do you deny that science can account for everything?” Scientism’s assumption that science can establish everything is self-refuting. Careful analysis shows that there is an infinite number of things that are true that we cannot prove scientifically and never will. Stephen Hawking saw the tip of the iceberg of this truth when he said, “Up to now, most people have…

AI: Still Just Curve Fitting, Not Finding a Theory of Everything

The AI Feynman algorithm is impressive, as the New York Times notes, but it doesn’t devise any laws of physics

Judea Pearl, a winner of the Turing Award (the “Nobel Prize of computing”), has argued that, “All the impressive achievements of deep learning amount to just curve fitting.” Finding patterns in data may be useful but it is not real intelligence. A recent New York Times article, “Can a Computer Devise a Theory of Everything?” suggested that Pearl is wrong because computer algorithms have moved beyond mere curve fitting. Stephen Hawking’s 1980 prediction that, “The end might not be in sight for theoretical physics, but it might be in sight for theoretical physicists” was quoted. If computers can now devise theories that make theoretical physicists redundant, then they are surely smarter than the rest of us. The program behind the…

Can a Powerful Enough Computer Work Out a Theory of Everything?

Some physicists hope so even if it would put them out of work. But is it possible?

Recently, prominent physicists were asked whether a sufficiently powerful computer could come up with a Theory of Everything, by the sheer power of crunching numbers. As a recent New York Times article by Dennis Overbye shows, physicists were divided and uncertain: “It might be possible, physicists say, but not anytime soon. And there’s no guarantee that we humans will understand the result.” But doubt, in the view of multiverse theorist Max Tegmark, means we are guilty of “carbon chauvinism”—the idea that humans could be smarter than computers. The late Stephen Hawking thought that computers would replace humans and was alarmed by the prospect. According to Overbye, Hawking had been warning that computers would start to replace physicists in particular since…
