This is Big: Astronomers Just Did What Einstein Said Was Impossible
When the theory of relativity was being mapped out, Einstein didn’t think that one of his predictions, the prediction that the light of a distant star being warped and magnified by the gravity of an object in its path, would ever be observed. Astronomers have laid eyes upon Einstein’s prediction and used it to their incredible advantage. They used such an observation to figure out the mass of a white dwarf! An idea inhabiting only theoretical dreams was dragged out into scientific reality in an incredibly fantastic manner. This idea was rejected by Einstein. Image Credit: NASA, ESA, and A. Feild (STScI) With mathematical equations dragged into our physical world today, a new path of understanding galactic evolution and history is now here. It’s time for a story. In order to fully understand the significance of this finding, a portion of Einstein’s legend and legacy demands narration. A key concept of Einstein’s theory of general relativity is gravitational lensing occurring...
