COLUMBIA, S.C. (WIS) - Gamma-ray bursts are a relatively new discovery in space science. The first burst was discovered in the late 1960s. You might be wondering ...

Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.

You might think astronomers have seen it all, but the universe still throws us occasional new mysteries to keep us on our toes. They aren’t that unusual to spot—the universe is so big and GRBs are so ...
