Most secular teaching claims that the universe came to be with a Big Bang; that there was a small infinitely hot and dense point billions of years ago which is called a singularity point. From this singularity, the teaching says, came all the matter and energy that evolved into all that exists today in our universe. Naturalists believe that the universe is infinite; that it has always existed. Different types of theories have continued to arise in an attempt to explain the origin of the universe including the steady-state theory espoused by Hermann Bondi, Thomas Gold, and Fred Hoyle, and many others that claim that the universe is infinite and that, in spite of entropy and the Second Law of Thermodynamics, new energy and matter continue to, somehow, be generated, replacing that which is used up with the passage of time. These are all attempts to repudiate what the Bible says about the beginning of the universe. But the Bible unequivocally insists that the universe had a miraculous beginning at a point when there was no time, no space or matter; a time when there were no laws of physics as we know them since these laws could not exist without the universe: “In the beginning God created the heavens and the earth…Then God said, “Let there be light…”” (Genesis 1:1,3).
In 1963-1965 when Arno Penzias and Robert Wilson, two engineers employed by Bell Laboratories, looked through a giant telescope of a Satellite Transmission System known as Echo, they saw a film of radiation enveloping the whole universe; the entire universe seemed to be bathed in a soft glow of light. This light became known as the Cosmic Microwave Radiation Background (CMRB).
Prior to this discovery, skeptics had contended that if the universe indeed had a beginning at a certain point in time with the explosion of light, then the vestiges of that light should still be present, somehow. Well, what do you know? Penzias and Wilson discovered the remainder of that light-a telltale sign of creation, as the Bible boldly proclaims… “Let there be light…”
Listen to Penzias’ comment following this discovery: “The best data we have are exactly what I would have predicted had I nothing to go on but the five books of Moses, the Psalms and the Bible as a whole.”1
Although the CMRB is invisible to the naked eye, it continues to shine in the microwave part of the electromagnetic spectrum all around the universe.
