In our universe: Time travel? “How a Rotating Universe Makes Time Travel Possible” At Universe Today, Stony Brook astrophysicist Paul Sutter notes that mathematical philosopher Kurt Gödel (1906–1978) wrote a model for Albert Einstein (1879–1955) of a universe that allows time travel into the past: “Gödel constructed a relatively simple and artificial model universe to prove his point. This universe is rotating and contains only one ingredient. That ingredient is a negative cosmological constant that resists the centrifugal force of the rotation to keep the universe static. / Gödel found that if you follow a particular path in this rotating universe you can end up in your own past. ” (January 11, 2023) Our universe, as it happens, is not Read More ›
Last month, Robert Lawrence Kuhn interviewed eminent British mathematical physicist Sir Roger Penrose on a number of topics, including the influence of surrealist artist M. C. Escher (December 9, 2022/32:00 min). Here is a transcribed selection from the second part of the discussion in Part 1 above*, beginning around the 12-minute mark, with some notes: Robert Lawrence Kuhn: We talked about the impossible Penrose triangle which really opens up another area of your life in terms of visual representations of remarkable things. Penrose tiling really new ways of thing of seeing visual representation of fiery fundamental geometric and algebraic transformations and things. But what I wanted to ask you is, as youdeveloped that you had this interaction with the artist Read More ›
Last month, Robert Lawrence Kuhn interviewed eminent British mathematical physicist Sir Roger Penrose on the relationship between mathematics, the mind, and the physical universe (December 9, 2022/32:00 min). Penrose likes to illustrate the relationship between the three with an “impossible” triangle (see below). Here are a couple of transcribed selections from the first part of the discussion in Part 1*, concerning the Penrose Triangle, with some notes: Robert Lawrence Kuhn: Let’s start with your grand metaphysical framework, your three worlds — three mysteries: the physical world, the mental world, the platonic or mathematical world — each connected to the other two in your famous diagram of an equilateral triangle. What’s the origin of this vision of yours of foundational reality? Read More ›
What does it even mean to be aware of something, to be conscious? Why do the vast majority of people only have one consciousness? Will computers ever experience consciousness? On this Bingecast, Dr. Robert J. Marks and Dr. Angus Menuge discuss these questions and more.

Two authors I’ve been reading recently are Roger Penrose and David Chalmers. Penrose is a physics Nobel laureate who has stoked controversy by claiming in The Emperor’s New Mind: Concerning Computers, Minds and The Laws of Physics (1989) that the mind can do things beyond the ability of computers. Chalmers is a philosopher of science who claims in The Conscious Mind: In Search of a Fundamental Theory (1997) that consciousness cannot be reduced to physical processes. Both thinkers are well respected in their fields, even though they articulate positions that imply that the mind’s operation is beyond current science. At the same time, they believe that there is a way to see the mind as part of nature (that is, Read More ›
In the 1960s, mathematician and computer scientist Gregory Chaitin published a landmark paper in the field of algorithmic information theory in the Journal of the ACM – and he was only a teenager. Since then he’s explored mathematics, computer science, and even gotten a mathematical constant named after him. Robert J. Marks leads the discussion with Professor Gregory Chaitin on Read More ›
At Forbes, theoretical astrophysicist Ethan Siegel comments: The true problem with the Universe is that there’s only one to observe, or at least, only one that we’re capable of observing. We don’t have a large sample of Universes to compare between, and we don’t have a large set of data points available to us within our Universe. It’s like rolling five dice, together, once. Your odds of getting all sixes is small: about 1-in-7800. Yet if you rolled five dice at once and saw that it came up all sixes, you wouldn’t necessarily conclude that it was anything more than random chance. Sometimes, nature just doesn’t give you the most likely outcome. It’s possible that the leftover photons from the Read More ›
The article “How an Artificial Superintelligence Might Actually Destroy Humanity” is one of the most irresponsible pieces about AI I have read in the last five years. The author, transhumanist George Dvorsky, builds his argument on a foundation of easily popped balloons. AI is and will remain a tool. Computers can crunch numbers faster than you or me. Alexa saves a lot of time looking up results on the web or playing a selected tune from Spotify. A car – even a bicycle – can go a lot faster than I can run. AI is a tool like fire or electricity used to enhance human performance and improve lifestyles. Like fire and electricity, AI can be used for evil or Read More ›
In Walter Bradley Center director Robert J. Marks’s second podcast with philosopher Angus Menuge, the big topic is the perennial “Hard Problem of consciousness and various proposed solutions. One of the questions that often comes up is quantum consciousness. Earlier, they had discussed Integrated Information Theory (IIT) and panpsychism. But now, what about recent Nobelist Roger Penrose’s approach: quantum consciousness? https://episodes.castos.com/mindmatters/Mind-Matters-134-Angus-Menuge.mp3 This portion begins at 18:22 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks (pictured): Okay. Another model of consciousness of which I am aware is so-called quantum consciousness. I’m really interested in this because reading the works of Roger Penrose, he maintains that humans can do non-algorithmic things. And he looked around at the Read More ›

In last week’s podcast, “The Chaitin Interview IV: Knowability and Unknowability,” Walter Bradley Center director Robert J. Marks interviewed mathematician Gregory Chaitin, best known for Chaitin’s Unknowable Number, on a number of things, including whether computers can show creativity. Chaitin has thought a lot about that: https://episodes.castos.com/mindmatters/Mind-Matters-127-Gregory-Chaitin.mp3 This portion begins at 21:34 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks: We’re talking, just in general, about the unknowable. Roger Penrose recently won a Nobel Prize for his work with Stephen Hawking on black hole theory. He also wrote a book called The Emperor’s New Mind: Concerning Computers, Minds and The Laws of Physics (1989) and he followed it up with The Shadows of the Mind: Read More ›

Readers will recall that we have been looking at science writer Matt Williams’s analysis of the various reasons that we do not see extraterrestrials except at the movies. Last week, we looked at the Firstborn Hypothesis: We don’t see aliens because they haven’t evolved yet. And, when they do, we must be careful not to harm their development through colonization. This week is a bit of a deeper dive: The extraterrestrials have evolved so far beyond us that perhaps we could not encounter them. … the Transcension Hypothesis ventures that an advanced civilization will become fundamentally altered by its technology. In short, it theorizes that any ETIs that predate humanity have long-since transformed into something that is not recognizable by Read More ›
If your mind is one, how can it talk to itself? What will artificial intelligence be like in the future. Dr. Geoffrey Simmons and Dr. Robert J.

Like Excel, AI assists programmers in their design work. AI can search through trillions of possibilities, using data from a million sources, to find a successful design. But the structure of the search and the source of the data is the choice of the programmer. A look at how famous inventors developed products that changed the world sheds some light on the process.
Exponential growth is often the beginning of a sigmoid or s-shaped curve where growth that appears to be exponential but eventually slows and reaches a saturation point. We see this in nature, for example, in bacteria.
Natural and artificial intelligence can be discussed from a number of viewpoints, including philosophically, technically and theologically. Robert J.

These prominent thinkers are driven to panpsychism because materialism about the mind doesn’t really work. So if panpsychism ends up seeming absurd, dualism—there really is an immaterial world—is also worth considering.
