BICEP2 experiment announced the detection of a significant amount of the primordial tensor mode polarization in the CMB power spectrum. Résonaances and Sesh Nadathur on the topic.
Europa Erupts! Possible Geyser of Water Seen on Jupiter’s Moon
So just the presence of water under Europa’s surface is exciting. But life also needs energy, and it needs raw materials. The fact that these geysers exist shows that plenty of energy is being pumped into the moon; it takes substantial power to blast water that high off the surface. It also indicates the surface and the ocean underneath interact with each other, which means raw material for life are available. Jupiter’s fierce magnetic field produces radiation, which reacts with molecules on the surface of Europa to create simple organic compounds
Un titolo troppo ad effetto, A Jewel at the Heart of Quantum Physics, ma una fonte ragionevolmente affidabile, Simons Foundation: com’è che nessuno ne parla?
Per fortuna l’articolo del Quanta Magazine è stato ripreso da slashdot in maniera abbastanza esagerata da spingere Peter “Not Even Wrong” Woit a dire due parole sulla questione.
