Recently, cosmologist Carlo Rovelli, author of The Order of Time, argued that time travel, especially into the future, can work. However, astrobiologist Caleb A. Scarf sees an insurmountable barrier, which he calls the “spatial problem”: Let’s take the Earth’s motion around the Sun. A month of orbit corresponds to moving in an arc of approximately 78 million kilometers. During that same period the entire solar system will have also moved approximately 600 million kilometers around our galaxy, and our entire Local Group of galaxies will have swept through about 1.7 billion kilometers of space relative to the cosmic microwave background. Not only do you need to traverse those kinds of distances, you need to get it correct to within a Read More ›

Delivered by comets. Abstract: We review the salient evidence consistent with or predicted by the Hoyle-Wickramasinghe (H-W) thesis of Cometary (Cosmic) Biology. Much of this physical and biological evidence is multifactorial. One particular focus are the recent studies which date the emergence of the complex retroviruses of vertebrate lines at or just before the Cambrian Explosion of ∼500 Ma. Such viruses are known to be plausibly associated with major evolutionary genomic processes. We believe this coincidence is not fortuitous but is consistent with a key prediction of H-W theory whereby major extinction-diversification evolutionary boundaries coincide with virus-bearing cometary-bolide bombardment events. A second focus is the remarkable evolution of intelligent complexity (Cephalopods) culminating in the emergence of the Octopus. A third Read More ›

From Sarah Chaffee and Granville Sewell at The Spectator:  Whether the standard neo-Darwinian mechanism fully explains the origins of biological novelties is a question that scientists themselves increasingly contest. Yet for the media, evolution is the holy Kaaba of science. Resistance verging on hysteria greets attempts to allow teachers to introduce mainstream controversies found in peer-reviewed scientific literature. Just look at media coverage about Arizona’s state science standards, currently being revised, where minor changes were decried as a wholesale “attack” on evolution. Louisiana passed its academic freedom law, the Louisiana Science Education Act, in 2008 and critics have been denouncing it ever since, dishonestly, for sneaking in instruction about “intelligent design” or “creationism.” Tennessee passed a similar law in 2012, Read More ›

… as the only way to save the species? From Bryan Walsh at Medium: “Our morality and our moral dispositions evolved to stop us from killing ourselves within our small group and to make sure that we cooperated with our small group,” says Savulescu, the Uehiro Professor of Practical Ethics at the University of Oxford. “But they didn’t evolve to provide benefits to strangers or to deal with large numbers of individuals at risk. All those features mean we’re particularly badly placed to deal with large statistical threats like the use of biological weapons or global collective action problems like climate change.” Essentially Savulescu believes that we “lack the moral capacities to deal with the sort of world we’ve created Read More ›

A recent book, Science and the Mind of the Maker: What the Conversation Between Faith and Science Reveals About God , by Melissa Cain Travis might be of interest. According to one of the Amazon reviews, One of the areas in the book that is unique and very interesting is the discussion about mathematics. The author states that, “Several eminent thinkers have convincingly argued that we discover, rather than invent, the realities of mathematics.” She cites numerous references from several scientists supporting this thesis, including Max Planck, Sir Arthur Eddington, Eugene Wigner and Roger Penrose. For example, physicist Wigner (an agnostic) wrote, “The enormous usefulness of mathematics in the natural sciences is something bordering on the mysterious. There is no Read More ›

Fr. Michael Chaberek author of Aquinas and Evolution, has built a website, Aquinas/Design to advance a philosophically responsible Catholic view on the question of design in nature: Thomistic evolutionists maintain that Aquinas’s philosophy/theology is incompatible with the modern theory of intelligent design (ID). At the same time they say it can be reconciled with neo-Darwinism. This may seem odd even for a non-Christian. There may be different reasons why Thomistic evolutionists chose to counter ID: Some may be ignorant of it, some may fear “the scientific community” and “the scientific consensus.” Still others may actually believe that arguments for ID somehow threaten the old Thomistic arguments for God’s existence known as the Five Ways. However, Thomistic evolutionists have never worked Read More ›

From computer engineering prof Robert J. Marks at Mind Matters Today: Fake and misleading AI news is everywhere today. Here’s an example I  ran across recently: A  headline from a large-circulation daily’s  web page screams: “No more secrets! New mind-reading machine can translate your thoughts and display them as text INSTANTLY!” Not just “instantly,” notice, but “INSTANTLY!” The Daily Mail is the United Kingdom’s second biggest-selling daily newspaper. … As with all hype, there is some truth in the piece. A headline like “New AI outperforms humans by a factor of a BILLION!” could be written about a calculator that computes specific values of trig functions. Calculating the cosine of 27.3 degrees from scratch to six significant places is a laborious Read More ›

Further to Carlo Rovelli’s views on time travel (only a technological problem, not a scientific one) and the order of time in general,  views, as set out in The Order of Time, our color commentator Rob Sheldon offers, — If I can speculate about what goes on in physicist’s heads, this issue about time is an attempt to force symmetry on the universe. Sorta like the 2-yr old who wants to regularize irregular verbs. “Mommy not home; she goed to the store.” Einstein’s Special Relativity (SR) argued that time was a fourth dimension and should not be treated any differently than height, width, and length. To get the units right, one only needed to multiply time by the speed of light–c*t. Only Read More ›

Not a scientific one. Dan Falk interviews physicist Carlo Rovelli about “about the nature of time, whether it has a beginning and if humans might one day master time travel:” Could time travel ever be possible? Well, “time traveling” is what we do all our lives, isn’t it? But you mean, can we jump quickly to the past or to the future. Jumping to the far future is certainly possible. It’s only a technological problem, not a scientific one. One way is to move very fast. When you move fast, time passes very slowly for you — so if you could run fast enough around your house many times, you could do that in a time span which for you Read More ›

From Cornelius Hunter at Evolution News and Science Today: A recent paper in the journal BIO-Complexity, authored by Winston Ewert, uses a dependency graph approach to model the relationships between the species. This idea is inspired by computer science which makes great use of dependency graphs for packaging of software and optimization of software architecture. Complicated software applications typically use a wealth of lower level software routines. These routines have been developed, tested, and stored in modules for use by higher level applications. When this happens the application inherits the lower-level software and has a dependency on those modules. … What Ewert has developed is a model to explain the pattern of similarities in different organisms that mimics how computer Read More ›

Headline in azcentral:  Renowned ASU professor Lawrence Krauss ousted from post after sex misconduct claims  

From ScienceDaily: “A paper published in 2002 (Enard et al., Nature 418, 869-872) claimed there was a selective sweep relatively recently in human evolutionary history that could largely account for our linguistic abilities and even help explain how modern humans were able to flourish so rapidly in Africa within the last 50-100,000 years,” says senior author Brenna Henn, a population geneticist at Stony Brook University and UC Davis. “I was immediately interested in dating the selective sweep and re-analyzing FOXP2 with larger and more diverse datasets, especially in more African populations.” Henn says that when the original 2002 work was done, the researchers did not have access to the modern sequencing technology that now provides data on whole genomes, so Read More ›

Even while prominent people in that field are coming to terms with the problem. From a New York Times science writer: It is one thing to frisk the studies appearing almost daily in journals that form the current back-and-forth of behavior research. It is somewhat different to call out experiments that became classics — and world-famous outside of psychology — because they dramatized something people recognized in themselves and in others. They live in the common culture as powerful metaphors, explanations for aspects of our behavior that we sense are true and that are captured somehow in a laboratory mini-drama constructed by an inventive researcher, or research team. Huh? Whether many people recognized something in themselves or not, the experiments Read More ›

From Jonathan Bartlett at Mind Matters Today: Bitcoin solves a lot of tough problems in very ingenious ways. Unfortunately, however, those benefits don’t tend to translate well for end users, who are not nearly as ingenious as the people developing the system. More. Readers will recognize Johnny Bartlett Jonathan Bartlett, Research and Education Director of the Blyth Institute, as a longtime author here.
