A Physicist Tries to Avoid the Fact of Design in Our Universe…
Physicist Alexander Vilenkin of Tufts University argues, against apparent fine-tuning, that our universe’s cosmological constant should have a special value like zero, but doesn’tIn his discussion with Robert Lawrence Kuhn at Closer to Truth, Tufts physicist and cosmologist Alexander Vilenkin addresses the question, “Is the Universe Fine-Tuned for Life and Mind?”: If the deep laws of the universe had been ever so slightly different human beings wouldn’t, and couldn’t, exist. All explanations of this exquisite fine-tuning, obvious and not-so-obvious, have problems or complexities. Natural or supernatural, that is the question. Vilenkin — who is also a professor of evolutionary science — concedes the main point: Alexander Vilenkin: [0:40] Well yeah that’s right. It appears that the Universe is fine-tuned in the sense that there are about 30 constants of nature which take some specific value: if you look at these numbers, they look Read More ›
How Quantum Theory Relates To Consciousness
Experimental physicist Rob Sheldon explains the background to Hameroff and Penrose’s contested quantum consciousness theory, which is beginning to be tested
The Theory That Consciousness Is a Quantum System Gains Support
Hameroff and Penrose’s Orch Or Theory sees consciousness as the outcome of a quantum collapse of a wave function
Will the Driving Force for Space Exploration Be a Religious Cult?
A Biochemist Begins To Sense the Limits of Materialism
William Reville seems both confident and uncertain at the same time that science can crack the problem of consciousness
If Science Were Just Bookkeeping, Fine-Tuning Wouldn’t Matter
Astrophysicist Marcelo Gleiser wishes we would just quit asking questions about why the universe is fine-tuned — as if we could…
The Multiverse: Better in Fiction Than in Real Life?
The multiverse may be “unscientific nonsense” or a “religious” belief, as some physicists assert but the rules of storytelling are not the laws of nature
Why are eccentric theories of consciousness tolerated?
Even prominent theorists have held eccentric theories of consciousness. It stems from the apparent impossibility of deriving human consciousness from the material substances of the brain
Can Roger Penrose Explain Consciousness Through Physics?
The Nobel Laureate physicist makes clear that he only wants a theory of human consciousness if the explanation comes down to physics
Does the Evidence for Our Universe’s Fine-Tuning Mean Anything?
Why is a divine Mind not “scientific” if the evidence points in that direction?
The Universe and its Mathematical Structure
Do humans project mathematics upon nature or vice versa?This past June, we published an article featuring a conversation between physicist Lawrence Krauss and novelist Cormac McCarthy, where they discussed whether mathematics was “discovered or invented.” Robert J. Marks went on to write his own thoughts on the question shortly thereafter. If you’re further interested in mathematics and whether there is an actual correspondence between math and the natural world, consider watching new podcast episode featuring Dr. Melissa Cain Travis. Do humans project mathematical order onto nature? Or was it there all along? On a new episode of ID the Future, I conclude a three-part conversation with Dr. Melissa Cain Travis about her recent book Thinking God’s Thoughts: Johannes Kepler and the Miracle of Cosmic Comprehensibility. In Part 3, we look Read More ›
The Big Bang: Last Summer, Doubt Suddenly Exploded. Why?
Why did a story that cast doubt on the Big Bang quickly go viral about a year ago? An experimental physicist offers some thoughts
Blinded by a Defunct Theory
The "interaction problem" is everywhere we look in physics, but the dogma of materialism remainsMaterialism. What a weird word. It sounds like a ghost, materializing in front of me. And it is sort of like a ghost, one that has mysteriously taken over the minds of many intelligent people. Because they believe in materialism, these smart people don’t believe in ghosts. Especially the ghost in the machine. The problem is there is no way for the ghost to interact with the machine. This is known as the “mind-body interaction problem”. The great thing about materialism is at least that theory doesn’t have an interaction problem. Any material thing can interact with any other material thing. Yet there is a deep irony. Let’s explore the idea of materialism to see why. Materialism is the idea that reality only consists of matter. Read More ›
The Search for Extraterrestrial Life 19
One current focus for exoplanet research is on the way life is known to alters its environment in order to remain in existence — the Gaian Habitable ZoneIn our universe: “Billions of celestial objects revealed in gargantuan survey of the Milky Way”: “The new dataset contains a staggering 3.32 billion celestial objects—arguably the largest such catalog so far”: “Most of the stars and dust in the Milky Way are located in its disk—the bright band stretching across this image—in which the spiral arms lie. While this profusion of stars and dust makes for beautiful images, it also makes the Galactic plane challenging to observe. The dark tendrils of dust seen threading through this image absorb starlight and blot out fainter stars entirely, and the light from diffuse nebulae interferes with any attempts to measure the brightness of individual objects. Another challenge arises from the sheer number of Read More ›
Physicist: Life After Death Is Incompatible With Physics
In 2011, Sean Carroll wrote an essay for Scientific American on why — from a science perspective — our minds must be extinguished at deathBack in 2011, particle physicist Sean M. Carroll wrote a guest blog at Scientific American, dismissing the idea of life after death or the immortality of the soul. He began by responding to astrophysicist Adam Frank’s reflections at NPR: For myself I remain fully and firmly agnostic on the question. If ever there was a place where firm convictions seem misplaced this is it. There simply is no controlled, experimental verifiable information to support either the “you rot” vs. “you go on” positions. In the absence of said information we are all free to believe as we like but, I would argue, it behooves us to remember that truly “public” knowledge on the subject — the kind science exemplifies — Read More ›
How Surreal Artist MC Escher Influenced Physicist Roger Penrose
Escher’s mathematical art was all the more remarkable because he had no formal training in mathematicsLast 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 ›
Nobelist Roger Penrose Talks About His Impossible Triangle
At Closer to Truth, the mathematical physicist explains to Robert Lawrence Kuhn how he understands the relationship between mathematics, the mind, and the physical worldLast 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 ›
A Physicist Rejects the Idea That We Live in a Sim Universe
At IAI News, Marcelo Gleiser worries that the claim that we are simulated beings with no free will reduces our ability to tackle the problems humanity facesDartmouth College physicist Marcelo Gleiser insists that the reality in which we live is not a simulation by advanced aliens or other intelligences — and that the fact that it isn’t is important. As the summary of his essay at IAI News explains, The idea that we are living in a simulation has become commonplace. Elon Musk, for example, thinks it is almost certain we are living in a simulation. But the simulation hypothesis comes up against insurmountable problems, and is, in the end, an excuse for us not to sort out our real moral failings… Marcelo Gleiser, “Reality is not a simulation and why it matters” at IAI News (January 4, 2023) The “simulation” idea may sound pretty far-fetched Read More ›
The Search for Extraterrestrial Life 17
Interest in moon exploration and bases is growing and it turns out there is more water there (carried by the solar wind) than thoughtIn our universe: We’re always learning new things now. The universe “has 2−3× more light than expected from the integrated light from galaxies” “According to new measurements by New Horizons, the light coming from stars beyond the Milky Way is two to three times brighter than the light from known populations of galaxies – meaning that there are even more out there than we thought! – Matt Williams, Universe Today, (December 24, 2022) The paper is open access. While we’re here, rogue stars may be even older than we thought: “”We don’t exactly know what made them homeless. Current theories cannot explain our results, but somehow they were produced in large quantities in the early universe,” James Jee, an astronomer Read More ›
