Reverend Robert Evans • Finds Supernovae • Dying stars • Able to find minute differences in the sky • “Imagine a standard dining room table covered in a black tablecloth and someone throwing a handful of salt across it. The scattered grains can be thought of as a galaxy. Now imagine fifteen hundred more tables like the first one[,] each with a random array of salt across it. Now add one grain of salt to any table and let Bob Evans walk among them. At a glance he will spot it. That grain of salt is the supernovae.” (Bryson, 30)
Supernovae • The explosions created by dying stars • Stars are usually larger than our sun • Releases energy of a hundred billion suns “burning for a time brighter than all the stars in the galaxy.” (Bryson, 30) “It’s like a trillion hydrogen bombs going off at once,” –Robert Evans • Biggest events in creation • Cause of cosmic rays • Term “Supernova” was created by Fritz Zwicky • Finding Supernova Quote (Brendan pg. 33)
