The idea that our universe may be just one among many out there has intrigued modern cosmologists for some time. But it looks like this "multiverse" concept might actually have appeared, albeit unintentionally, back in the Middle Ages. When scientists analyzed a 13th-century Latin text and applied modern mathematics to it, they found hints that … Continue reading How a Medieval Philosopher Dreamed Up the ‘Multiverse’ | Space.com
RealClearScience – End the Hype over Epigenetics & Lamarckian Evolution
You might recall from high school biology a scientist by the name of Jean-Baptiste Lamarck. He proposed a mechanism of evolution in which organisms pass on traits acquired during their lifetimes to their offspring. The textbook example is a proposed mechanism of giraffe evolution: If a giraffe stretches its neck to reach higher leaves on … Continue reading RealClearScience – End the Hype over Epigenetics & Lamarckian Evolution
Microbes May Have Fueled Permian Extinction, Earth’s Biggest
A microbial feeding frenzy may have fueled the biggest mass extinction in Earth's history, new research suggests. The findings suggest that bacteria, with a little help from massive volcanism, produced large quantities of methane, thereby killing 90 percent of life on the planet. more at Microbes May Have Fueled Permian Extinction, Earth's Biggest.

I had a couple of people ask me to post any answer I might eventually find. … Continue reading The cosmological horizon problem answer, I think

How was he going to take a 300 page book and turn it into six to nine hours of film? When I watched the first movie, I was pleasantly surprised. The … Continue reading The Hobbit: The Desolation of Smaug
Science and naturalism
Sean Carroll has an interesting piece at The Stone on the New York Times site, pointing out that the theory of cosmic inflation was motivated by naturalism. In other words, it was motivated by the desire to find a natural explanation for something that didn't look natural, such as the apparent fine tuning necessary for the … Continue reading Science and naturalism
