How did the universe get here? Scientists confirm the Big Bang Theory and the beginning of the universe.
Scientists believe that our universe began with one enormous explosion of energy and light, which we now call the Big Bang. This was the singular start to everything that exists. The beginning of the universe, the start of space, and even the initial start of time itself. Nothing we observe today existed prior to that exact moment.
Further, it was something outside of time, outside of space, and outside of matter that caused all of this to come into existence.The realization that our universe started, and did not always exist, brings enormous challenges to nontheistic scientists.
Are scientists certain of this Big Bang Theory? Yes. In the late 1920’s, astronomer Edwin Hubble saw through his telescope that galaxies (some millions of light years away) were hurtling away from each other at fantastic speeds. This was not caused by some force thrusting them away from each other. Rather, they were still moving as a result of a primeval explosion, all from one point of origin.
In this point of origin, all the mass in the universe was compressed into a single point of infinite density…smaller than a single atom.2 Then in a cosmic explosion–the Big Bang–the universe came into being. Steven Weinberg, a Nobel laureate in Physics, gives further description, “At about one-hundredth of a second, the earliest time about which we can speak with any confidence, the temperature of the universe was about a hundred thousands million (1011) degrees Centigrade. This is much hotter than in the center of even the hottest star, so hot, in fact, that none of the components of ordinary matter, molecules, or atoms, or even the nuclei of atoms, could have held together.”3 He goes on, “The universe was filled with light.”
This eerily parallels the record, “In the beginning, God created the heavens and the earth…and God said, ‘Let there be light,’ and there was light.”4 It came about not from matter, but from pronouncement. A spoken word. “Let there be light.”
Looking at the sacred texts of all the major religions, only the Bible describes what scientists have since discovered: there was an explosion of light and a beginning to our universe…from outside of the universe itself. With it came the very start of space, matter and time. It was a singular starting point for everything. Over and over in the Book of Genesis is the description, “And God said….” followed by “…and it was so.”
Instead, could our universe have come about through the laws of physics: such as gravity, electromagnetism, speed of light, etc.? No, because those things did not yet exist. The initial start of the universe itself produced the laws of physics and everything began without them.
