European astronomers have spotted a new outburst of the accreting millisecond X-ray pulsar designated SAX J1748.9-2021. The outburst, which started on September 29, 2017, is fainter and shorter than previous outbursts of ...
Einstein's understanding of gravity, as outlined in his general theory of relativity, predicts that all objects fall at the same rate, regardless of their mass or composition. This theory has passed test after test here on ...
