Take chemistry, add energy, get life. The first tests of Jeremy England’s provocative origin-of-life hypothesis are in, and they appear to show how order can arise from nothing.
Supernova hunters were able to train their telescopes on a recent eruption just hours after it exploded. What they found only adds to the growing list of questions surrounding these cosmic blasts.
The team that discovered gravitational waves put their data online. Now an independent group of researchers claims that they’ve found what might be a serious problem.
Breathless media coverage notwithstanding, the cases for and against a hypothetical Planet Nine in the outskirts of the solar system remain inconclusive.
The newly developed theory of emergent gravity, proposed as an alternative to dark matter, struggles in one of its first trials.
Recent calculations tie together two conjectures about gravity, potentially revealing new truths about its elusive quantum nature.
Does the force of gravity change at large scales? Perhaps not, but a new theory of dark matter shows why that could appear to be the case.
A different kind of dark matter could help to resolve an old celestial conundrum.
New math shows how, contrary to conventional scientific wisdom, conscious beings and other macroscopic entities might have greater influence over the future than do the sum of their microscopic components.
