Wow. Somewhat in balance to yesterday's reblog of part one of Coel Hellier's post defending multiverse theories as scientific, here's Amir Aczel skewering many of the proponents of multiverses and other untestable cosmological theories. He takes aim at Brian Greene, Max Tegmark, Lawrence Krauss, and others, for presenting metaphysical assertions as science. The universe is a marvelous … Continue reading Pseudophysics: The New High Priesthood

Max Tegmark and MinutePhysics on the mathematical universe
This is a subject that we've discussed repeatedly here, so I thought you might find Tegmark's narration of this video interesting. http://www.youtube.com/watch?v=HGG4HmlotJE I'm pretty sure that mathematics are not only something humans created, that they are based on relations we observe in the world, but beyond that, I remain largely agnostic on the Mathematical Universe Hypothesis … Continue reading Max Tegmark and MinutePhysics on the mathematical universe
I don’t share Stephen Hawking’s worry about AIs
This essay by three physicists: Stephen Hawking, Max Tegmark, Frank Wilczek, along with Stuart Russell (the one computer scientist), seems to be getting a lot of attention. It keeps popping up in my various feeds, showing up in various venues. With the Hollywood blockbuster Transcendence playing in cinemas, with Johnny Depp and Morgan Freeman showcasing clashing visions … Continue reading I don’t share Stephen Hawking’s worry about AIs
Max Tegmark posts his chapter on cosmic inflation online
If you enjoyed my write up on Tegmark's Level II multiverse, you might enjoy this guest post that he makes on Sean Carroll's blog, which includes a link to the chapter on inflation from his book, including those visual aids I referenced! Since the BICEP2 breakthrough is generating such huge interest in inflation, I’ve decided … Continue reading Max Tegmark posts his chapter on cosmic inflation online
Tegmark’s Mathematical Universe Hypothesis
I recently read Max Tegmark’s latest book, ‘Our Mathematical Universe‘, about his views on multiverses and the ultimate nature of reality. This is the fourth and final post in a series on the concepts and views he covers in the book. The previous entries were: Tegmark’s Level I Multiverse: infinite space Tegmark’s Level II Multiverse: bubble universes … Continue reading Tegmark’s Mathematical Universe Hypothesis
Tegmark’s Level III Multiverse: The many worlds interpretation of quantum mechanics
I recently finished reading Max Tegmark’s latest book, ‘Our Mathematical Universe‘, about his views on multiverses and the ultimate nature of reality. This is the third in a series of posts on the concepts and views he covers in the book. The previous entries are: Tegmark’s Level I Multiverse: infinite space Tegmark’s Level II Multiverse: bubble universes Tegmark … Continue reading Tegmark’s Level III Multiverse: The many worlds interpretation of quantum mechanics
Tegmark’s Level II Multiverse: bubble universes
I recently finished reading Max Tegmark’s latest book, ‘Our Mathematical Universe‘, about his views on multiverses and the ultimate nature of reality. This is the second in a series of posts on the concepts and views he covers in the book. Tegmark postulates four levels of multiverse. In the first post of this series, I described Termark's Level I … Continue reading Tegmark’s Level II Multiverse: bubble universes
Tegmark’s Level I Multiverse: infinite space
I've just finished reading Max Tegmark's latest book, 'Our Mathematical Universe', about his views on multiverses and the ultimate nature of reality. This is the first in a series of posts that I plan to do on it. Tegmark postulates four levels of multiverse. This post is about the first, and simplest version, the Level I … Continue reading Tegmark’s Level I Multiverse: infinite space
What is mathematics about? – James Franklin – Aeon
James Franklin has an interesting piece today at Aeon, asking what exactly mathematics is. He looks at Nominalism and Platonism, but discounts both in favor of Aristotelian Realism, which is something I'd not heard of before but seems equivalent to the idea that mathematics is empirical. What is mathematics about? We know what biology is about; … Continue reading What is mathematics about? – James Franklin – Aeon
You say multiverse, I say galaxies
Corey Powell has an interesting post up on what he calls the Four Great Eras of Exploration. The first era was Galileo's discovery of the vastness of the universe, the second that stars were composed of chemical elements, and the third was Hubble's discovery of other galaxies. The fourth, and main topic of his post, … Continue reading You say multiverse, I say galaxies
