Supernova Description (Brendan pg. 30)

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
