According to a new paper, white holes, the theoretical opposite of black holes, may account for dark matter, and may even predate the universe. They may even, according to Carlo Rovelli, explain the direction of time: A black hole is one prediction of Einstein’s theory of general relativity. Another is known as a white hole, which is like a black hole in reverse: Whereas nothing can escape from a black hole’s event horizon, nothing can enter a white hole’s event horizon. … In the 2014 study, Rovelli and his team suggested that, once a black hole evaporated to a degree where it could not shrink any further because space-time could not be squeezed into anything smaller, the dying black hole Read More ›

And, it turns out, they must: Zebrafish aren’t just surrounded by liquid, but turn liquid – in part – during their development. As the zebrafish embryo develops from a ball of cells to a fully-formed fish, a region of the embryo switches its phase from viscous to liquid in a process known as fluidity transition. Such fluidity transition has long been speculated to exist in living matter, but is described for the first time to occur in a living organism in a study published today in Nature Cell Biology. The study was carried out by the group of Carl-Philipp Heisenberg at the Institute of Science and Technology Austria, with first author and Postdoc Nicoletta Petridou, and together with the group Read More ›

In an ongoing discussion with hazel and others in another thread, some agreement has been reached that conceptual elements of mathematics (and in a related relationship, geometry) are things we discover rather than invent, such as circles and their mathematical properties. That discussion, IMO, could benefit by discussing what is meant by the term “Platonic Realm”. It seems to me that this issue turns on a very simple question; do we live in a universe that is matter-centric or consciousness-centric? What is the primary, driving force of the physical universe – mind or matter? IMO, quantum experimentation over the past 150 or so years makes the case that consciousness/mind is at least one of the fundamental aspects of even material Read More ›

The Blyth Institute’s new journal will offer a focus on artificial intelligence and philosophy as well as philosophical questions in mathematics and engineering The Blyth Institute, a think tank that explores the relationships between biology, cognitive science, and engineering, has launched a new journal, Communications of the Blyth Institute with Eric Holloway as Managing Editor and Jonathan Bartlett as Associate Editor. Communications is intended as a discussion forum for fresh ideas in a variety of areas, including philosophy of mind as seen from a computer science perspective. It is open to ID-friendly ideas. The inaugural issue covers such topics as Eric Holloway, Creativity and Machines, 13 Jonathan Bartlett, Simplifying and Refactoring Introductory Calculus, 17 T. M. Koch, Recategorizing the Human Read More ›

is Think!: The worst trap that people who are pursuing automation fall into is the desire to automate everything. That’s usually a road to disaster. Automation is supposed to save time and money, but it can wind up costing you both if you don’t carefully consider what you automate. How Automation Goes Wrong Elon Musk found this out the hard way. His original dream called for the Model 3 to be built almost entirely by robots. He believed that automation would increase the speed and decrease the costs of his production line. However, as GM found out in the 1980s, when an automated line goes wrong, you wind up automating failure instead of success. Apart from the fact that the Read More ›

Researchers have found that the presence of oxygen in a planet’s atmosphere may not be a strong indicator of life: Simulating in the lab the atmospheres of planets beyond the solar system, researchers successfully created both organic compounds and oxygen, absent of life. The findings, published Dec. 11 by the journal ACS Earth and Space Chemistry, serve as a cautionary tale for researchers who suggest the presence of oxygen and organics on distant worlds is evidence of life there. “Our experiments produced oxygen and organic molecules that could serve as the building blocks of life in the lab, proving that the presence of both doesn’t definitively indicate life,” says Chao He, assistant research scientist in the Johns Hopkins University Department Read More ›
