5+ day, 21+ hour ago   (348+ words) Physicists around the world remain deeply divided on key mysteries of the universe, from dark matter to quantum gravity. The standard cosmological model failed to gain majority support, and no leading theory dominated the survey results. The largest survey ever…...

5+ day, 21+ hour ago   (948+ words) An analysis of 75 meteorite falls identified seven distinct processes that occur as space rocks melt, break apart, and slow down before reaching the ground. Their results show that melting and fragmentation, rather than evaporation alone, determine how these objects shed…...
