Sean Carroll: The multiverse might be impossible to test directly. Even if such a theory were true, the worry goes, how would we ever know? Is it scientific to even talk about it?
In 1937, after the rise of quantum mechanics, Ettore Majorana, an Italian theoretical physicist, realized that the new physics implied the existence of a novel type of particles, now called Majorana fermions. After a 75-year hunt, researchers have now spotted the first solid evidence of their existence. And their discovery could hold the key to…
Many mysteries surround black holes, but new research led by the Niels Bohr Institute has come up with groundbreaking new theories that might explain several of their more mysterious properties. The new study reveals that black holes have properties that resemble the dynamics of both solids and liquids. Black holes are extremely compact, so compact…
ESA’s Planck satellite has delivered its first all-sky image of the Cosmic Microwave Background (CMB), bringing with it new challenges about our understanding of the origin and evolution of the cosmos. The image has provided the most precise picture of the early Universe so far. For the most part, the data agree extremely well with…
The most crowded alien planetary system found yet possesses five worlds all orbiting a star at least 12 times closer than Earth does the sun, researchers say. KOI-500 is a super-compact planetary system, the most tightly packed one seen yet, hosting at least five planets ranging from 1.3 to 2.6 times the size of Earth….
None of us would be here today if, billions of years ago, a tiny, single-celled organism hadn’t started using oxygen to make a living. Researchers don’t know exactly when this happened, or why, but a team of scientists has come closer than ever before to finding out. They’ve identified the earliest known example of aerobic…
SciAm excerpts Maria Konnikova’s “Mastermind: How to Think Like Sherlock Holmes“: “It is surprising that people do not believe that there is imagination in science,” Nobel-winning physicist Richard Feynman once told an audience. Not only is that view patently false, but “it is a very interesting kind of imagination, unlike that of the artist. The…
