Ask Ethan: Could The Energy Loss From Radiating Stars Explain Dark Energy?
... and try and arrive at a numerical answer. This maddeningly difficult property of spacetime, that it's so hard to characterize exactly, is why it's taken such tremendous computing power, theoretical work, and so much time in order to properly model ...

A Rare Black Hole Just Swallowed A Star
Since their discovery, the only acknowledged black hole varieties represent two extremes: one could swallow the sun, and the other could swallow an entire galaxy. Scientists have long sought proof of mid-size black holes that could fill the gap, and ...
