Penguin ISBN 978-0-713-99857-3 A$59.95 242 pages ![]() The story begins 14 billion years ago. Somewhere in a vacuum (one school of thought would have it), a quantum ripple upset the apple cart and – BAM! One-ten-thousand-billionth of a second later a ball of pure energy, 1029 degrees Kelvin, begins its inevitable task, as described by the Standard Model of particle physics, of creating the universe. Energy turns into X and Anti-X particles, which become quarks and leptons, which form nuclei – and slowly a balance is achieved between matter and the mysterious dark matter that holds the galaxies in place. British science writer John Gribbin is known for his accessible works on complex subjects but he has met his match here. That’s kind of his point, however. As he signposts what is still conjecture, Gribbin crafts thorough explanations from what is known about matter and uses the Standard Model to wind back time and ponder the universe’s birth and childhood. As Gribbin moves through the history of the universe, there are moments of great excitement and wonder as he explains what scientists think happened 10-13 seconds after the Big Bang and describes how it might all end. Included along the way are: the theory of inflation (which relies on quantum fluctuations during the first moments after time zero to explain the uniformity of the universe and why galaxies exist at all); where our chemical elements came from; how our Solar System was made; and how life on Earth originated about four billion years ago. There is no happy ending to this story, however. Every biography ends with a death and our universe’s demise is certain, as stars burn out, protons decay and electrons meet positrons then disappear in a flash of gamma rays. Life on Earth will end a long time before then, of course, and human life might well be wiped out by a major extinction, of which there have been five before now (the first, 440 million years ago; the most recent, 65 million years ago). So, let’s enjoy the universe while we can, and a good way to start is by reading this book. Know or not know?Gribbin repeats the phrase “what we think we know, rather than what we think we know” – which, no matter how many times you read it, always leaves you hanging in space.

The Multiverse
Let us understand the multiverse before we are wiped out once again.

What is the relevance of a multiverse?
I believe that "homo sapiens" are a mere "accidental" happening of cosmic evolution, and that in the long run, they will, as a result of "natural selection" disappear as the Universe continues to evolve. After the disappearance, who knows how matter, energy, and spacetime will once again re-organize itself again as it continues to evolve? The current organization of matter and energy we call "homo sapeins" and "the World" while interesting, is an inadequate one at best: the basic question should be "is it possible for a future 'intelligent' organization(s) of matter and energy to be truly capable of peace, justice, and more?" Is there another meta organization of matter and energy that can be called truly "intelligent"?
