Space is Negative Energy

The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materiahse out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy."

To help you get your head around this weird'd but crucial concept, let me draw on a simple analogy Imagine a man wants to build a hill on a flat piece of land. The hill will represent the universe. To make this hill he digs a hole in the ground and uses that soil to dig his hill. But of course he's not just making a hill— [c's also making a hole, in effect a negative version of the hill. The stuff that was in the hole has now become the hill, so it all perfectly balances out. This i the principle behind what happened at the bcbeginning of the universe.

when the Big Bang produced a massive amount of positive energy, it simultaneously produced the same amount of negative energy. In this way, the positive and negative add up to zero, always. It's another law of nature.
