It is quite hard to visualize a time, approximately 13.7 billion years ago, when the whole universe existed as a singularity. According to the big bang theory, one of the key contenders struggling to describe how the universe came to be, all the matter in the universe -- all of space itself -- occurred in a form minor than a subatomic particle. When you think about that, an even tougher question arises: What precisely existed just before the big bang happened? The question itself exists before current cosmology by at least 1,600 years. Fourth-century theologian St. Augustine struggled with the nature of God before the formation of the cosmos. So what was his answer?
Time was part of God's formation, and there basically was nothing like "before" that a deity could call home. The famous physicists, Albert Einstein, came to very parallel deductions with his theory of relativity. Just think about the effect of mass on time. A planet's immense mass bends time -- making time run a little bit slower for a person on Earth's surface than a person on s satellite in orbit around Earth. The change in the speed of time is too minor to notice.
The pre-big bang singularity controlled all the mass in the cosmos, efficiently passing time to a standstill. Following this route of logic, the heading of this article is essentially flawed. According to Einstein's theory of relativity, time only came into existence as that primeval singularity stretched toward its current size and shape. Case solved? Well nope.
This is one cosmological difficulty that won't stay dead. In the decades after Einstein's death, the beginning of quantum physics and a host of current theories revived questions about the pre-big bang universe. So, what existed before the big bang is still an open question and needs to be answered. Maybe another universe or a different form of our own universe existed before the Big Bang Or maybe a sea of universes, every universe with a different set of laws governing its physical reality.
So what are your views about what existed before Big Bang?????
