Quotes from Mary Kay Carson

The Big Bang theory says that billions of years ago, a great explosion created all of space, matter, light, and even time. The clock of the cosmos starting ticking as all the stored energy in the explosion changed into matter. Einstein's E = mc2 explains it, actually. An enormous eruption of energy flies apart, converting E into mass, or m. The earliest matter was just particles and atoms, but those eventually formed stars, solar systems, and planets.
