The Big Bang Theory – “In the beginning there was nothing; during and after that moment there was something: our universe. According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know.” (http://big-bang-theory.com/) 

I was watching science channel and heard some scientists explain this. Let us back track, I will start from what is a Star. 

A star is comprised on Nuclear Fusion reaction (shakti/intelligence) of hydrogen in the core, and there is gravity (Bhakti/Love) from outside trying to squeeze in. The balance between these 2 forces creates / maintains a star in stable form. When star’s life ends it creates a lot of elements that form smaller stars and planets and Solar system. So who is our ancestor, in true terms it is a Star that died and gave birth to our Sun and planet earth and then us. 

How are star’s formed ? Dust and hydrogen cloud in space called "Nebula" comes in contact with Gravity and when Gravity is very intense there is nuclear fusion reaction and star is formed when this gravity is balanced with fusion reaction of hydrogen. That is the beginning of creation of building blocks of our solar system. 

When there is a balance of 2 forces - nuclear fusion (Shakti/Intelligence) & Gravity (Bhakti/Love), there is creation. This is also called the duality. This duality exists everywhere in our lives. 

My Guru told me once, when you can maintain balance between Shakti & Bhakti, you will realize Divine. As beyond this Duality there is only Divine. 

Let’s try to answer the Big Bang Theory. If all of the creation is because of imbalance of duality, then there cannot be a singularity. The only thing that is single or absolute is Divine itself. This is explained by scientists as “Nothingness”. 

 All you have to decide is whether you came from Nothing or you came from Divine the Absolute. 

Those who still want to believe "Nothing created Something", think about it, nothing cannot create something as they are totally opposite. Only that which is Nothing+Something = Absolute=Divine can create them or only at Absolute, duality does not exist, hence the Absolute=Divine and not Nothingness. 

 The cheat sheet - 

Gravity/Love/Bhakti & Fusion/Intelligence/Shakti = Duality 

Duality(Balance) = Divine 

Duality (Imbalance) = Creation 

Divine = Absolute <> Nothingness
