the BIG BANG theory states that  "when two 'objects' collide head-on, they produce sound which can vary from minor hissing to loud banging depending upon the impact of collision and is followed by an emanation and effervescence of  byproducts in the form of steam, heat and liquid."


Just like the theorist himself, the BIG BANG theory is versatile, dynamic and is subject to modification with time/evolution. The latest addendum to the theory states:

"When one object is rear-ended by the other, it produces similar effect (sound and followed by byproducts) as in the case with head-on collision but contrary to head-on, the byproducts in this kind of impact have minimum effect in the long run on the object which is rear ended."
