"In the 1960s two scientists[*] practically by mistake stumbled onto one of the greatest discoveries of modern science. They picked up of an unexplainable static on a measuring device leading them ultimately to discover the background static of the 'big bang,' [...]
"Just as there is a background sound permeating all the universe as a result of the initial instant of the big bang, we can say similarly that there is a spiritual background voice in the world resulting from the giving of the Torah at Sinai, an event that actualizes God's purpose for creation. Just because we don't hear the sound of the big bang doesn't mean it's not there. Similarly, just because we don't hear the voice emanating from Mt. Sinai everyday doesn't mean it's not there to be heard."

[*] I believe he's referring to Arno Penzias and Robert Wilson discovering the cosmic microwave background radiation.
