Then, in a single fraction of a moment, gravity and all the other forces that govern physics were produced. This was the Big Bang, the moment when everything began, including space and time. One not-so-very special day about 13.7 billion years ago, for some mysterious reason, the singularity, figuratively speaking, just exploded. Yet, it contained within itself all the energy and space-time of the known universe. The initial singularity was so compact it practically had no dimensions. Scientists nowadays refer to this spot as a singularity. Next, you’ll need to gather up everything there is in our universe and squeeze it into that tiniest of spots. And yet, if you want to understand how our universe began, you’ll need to shrink one of those protons down to a billionth of its normal size. There are more protons in the dot of an “i” than there are seconds in half a million years. In case the title itself isn’t a giveaway, “A Short History of Nearly Everything” is a book about “how we went from there being nothing at all to there being something, and then how a little of that something turned into us, and also what happened in between and since.” That’s a lot of ground to cover, so get ready for the intellectual odyssey of a lifetime! Lost in the cosmos
