The Big Bang Theory

Our Universe Sprang Out Of Nothing In About 15 Billion Years Ago
(The Nothing Can Be Exchanged With Singularity)
What Is Singularity?
Singularity Is Something That Is Compacted With Infinite Density In A Tiny Space
Where Does It Come From?
We Don't Know! Some People Say That It Came From God. But It Will Only Make The Problem More TroubleSome, Because Somebody Will Then Ask : Where Do/Does God/Gods/Goddess/Goddesses Come From?

Lets Get Back To The Point!
The Universe Started To Pop Out Either In An Explotion Or Just Kept Expanding Instead
The Universe Continues To Expand Till Today
And It Expand, The Heat Also Spreads
Its May Expand From The Size Of This Dot . To The Uncountable Size Of The Universe Now

Evidence Of This Theory
~ First Of All , We Are Certain That The Universe Of Course Has A Explainable Beginning
~ Second , We Already Got Prove That Galaxies Are Moving Away From Each Other Intensely
This Means That The Universe Is Expanding
If You Opposite It , The Universe Is Getting Smaller And Smaller
And At Last It Will Turn Into Singularity!

My Add-ons
Since It Will Expands (Expanded 15 Billions Years)
Why Not It Gets Smaller The Next 15 Billions Years
Because Of Its Over Expanding And The Coldness
It Will Collapse And In the End Turn Back Into The Singularity Thingy
