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

If you're well read in science, a lot of this might … Continue reading Neil deGrasse Tyson in ‘The Inexplicable Universe’

First potentially habitable Earth-sized planet confirmed by Gemini and Keck observatories — ScienceDaily

This is a pretty big milestone.  The first Earth sized planet in a star's habitable zone.  Pity it's so far away (500 light years) that spectral analysis probably won't be possible to figure out what its atmosphere has in it. The first Earth-sized exoplanet orbiting within the habitable zone of another star has been confirmed … Continue reading First potentially habitable Earth-sized planet confirmed by Gemini and Keck observatories — ScienceDaily

Neanderthals and Cro-magnons did not coexist on the Iberian Peninsula, suggests re-analysis of dating — ScienceDaily

The meeting between a Neanderthal and one of the first humans, which we used to picture in our minds, did not happen on the Iberian Peninsula. That is the conclusion reached by an scientists after redoing the dating of the remains in three caves located on the route through the Pyrenees of the first beings … Continue reading Neanderthals and Cro-magnons did not coexist on the Iberian Peninsula, suggests re-analysis of dating — ScienceDaily
