Big Bang and Realities

"I am sure you have heard of the big bang. The so-called 'creation of the universe' is what you humans like to call it."

Asura quoted 'creation of universe' with his fingers.

"Seriously, that's the most ridiculous discovery of human civilization so far. But they are far off from the truth. I will keep everything short and get straight to the topic. After all, you are my enemy."

A brief pause later, Asura continued, "A reality is a period between one 'big bang' to another. One reality gets destroyed, and another is created. But there are multiple things to keep in mind.

Just because one reality gets destroyed doesn't mean a new one will be created. And that also doesn't mean that the people living in reality died or went extinct.
