Ever wonder how big the Big Bang had to be to create the universe?
Now imagine a balloon filled with water. If you squeeze it tightly to reduce its size, the water inside will push back. If the resisting force becomes stronger than the balloon's durability, it will burst, and all that internal pressure will be released outward. But because of friction and air resistance, the force gets reduced.
So, the larger the amount of water and the stronger the balloon, the bigger the resulting explosion will be.
Now imagine the water is all the matter in the universe. The balloon's durability is just enough to compress it to a single point, and there is nothing else to resist the force. And that's when you get the Big Bang.
What if "Nothing" actualy stop it? What if the void around it actually resisted the expainsion of space from the sigularity? And that where our weird story took place.
