Rogan and Astrophysicist Talk Aliens and UFOs

Are we really the only (intelligent) beings out here?

By David Klinghoffer Our astrophysicist friend Brian Keating from UC San Diego was on the Joe Rogan Experience — for three and a half hours, much as philosopher of science Stephen Meyer was recently. I’ve listened to the whole thing. Very interesting! And with shout-outs to Dr. Meyer on a couple of points that Dr. Keating offers for consideration: that religious faith prepared the way for modern science by teaching the intelligibility and order of nature, and that what really got Galileo in trouble was challenging not the Bible but Aristotle, who had in effect (but not literally) been embraced as a saint by the Catholic Church. Watch and listen here on Spotify. From Another World, or Our Own? The conversation is very wide-ranging, as Read More ›

But Do “Hidden Webs of Information” Really Solve Life’s Mystery?

Cosmologist Paul Davies won an award last year for an attempt that left “more questions than clean-cut answers (Physics World)

Last year, State University of Arizona’s cosmologist Paul Davies won a Best Book award from Physics World for Demon in the Machine: The book’s subtitle is “How hidden webs of information are solving the mystery of life.” But are they? The book deals with established physics concepts (such as the second law of thermodynamics), but also delves into Davies’ thoughts on topics such as the emergence of human consciousness (while making sure the reader is aware of what is speculation). Readers, though, are likely to be left with more questions than clean-cut answers about the laws of nature. “Just in the last 10 years or so, I suppose, I’ve begun to see a confluence of different subjects. Partly, this is Read More ›

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 Read More ›

Could AI Understand the Universe?

World-renowned chemist thinks it might understand what we can’t, including consciousness
Atkins is arguing that the fact that we do not understand what consciousness is, far from being a barrier to creating artificial consciousness, offers the hope that, once we do create them, artificially conscious entities will understand consciousness but we won’t. The proposition sounds a bit confused, no?
