Where did the universe come from?(from the Universe Forum, NASA, the Harvard Smithsonian Center for Astrophysics)No one knows how the first space, time, and matter arose.scientists are grappling with even deeper questions:And• If there was NOTHING to begin with, then where did the laws of naturecome from?• How did the universe "know" how to proceed?• And why do the laws of nature produce a universe that is so hospitableto LIFE?As difficult as these questions are, scientists are attempting to addressthem with bold new ideas — and new experiments to test those ideas.SRC, Warsaw, 3 October 2013 9
In Search of Quantum GravityUnderstanding how the universe began requires developing a bettertheory of how space, time, and matter are related. In physics, a theory isnot a guess or a hypothesis. It is a mathematical model that lets us makepredictions about how the world behaves. Einstein’s theory of gravity, forexample, accurately describes how matter responds to gravity in the largescaleworld around us.And our best theory of the tiny sub-atomic realm, called quantumtheory, makes very accurate predictions about the behavior of matter attiny scales of distance.But these two theories are not complete and are not able to makeaccurate predictions about the very earliest moments when the universewas both extremely dense and extremely small.SRC, Warsaw, 3 October 2013 10
