 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 univ...

 The Universe as a Game Where the Rules are Hidden

‘I talked to a woman of the Kaminari once,’ he says, ‘before the Spike. Don’t give me such a look, it wasn’t like that, we were just friends. But one night on Ganymede, we got philosophical.

 The Universe is Just Right Intellectually

For myself, I like a universe that, includes much that is unknown and, at the same time, much that is knowable. A universe in which everything is known would be static and dull, as boring as the heaven of some weak-minded theologians. A universe that is unknowable is no fit place for a thinking being. The ideal universe for us is one very much like the universe we inhabit. And I would guess that this is not really much of a coincidence.

 The Realization That the Universe May End

In a bravura passage, Darwin also considers Herschel’s disturbing suggestion that the entire cosmos may eventually wither back into ‘one dark centre’. This implies that the universe not only had a beginning, but will have a physically destructive end, a ‘Big Crunch’. There are hints here too of Milton’s vision of the falling rebel angels dropping out of the firmament in Book I of Herschel’s favourite, Paradise Lost. This itself had possible political overtones for a reader in th...

The historical realization that the Universe might die in a "crunch" was followed by the idea that it might rise again like a phoenix.
