I am reading this book by a cosmologist where he is talking about how the universe must be pretty old to be able to produce observers to figure out how old the universe is. This makes sense. The universe must be at least billions of light years in size to have had the time to produce the elements to produce life. The point I am wondering about is when he says that a universe that was only the size of the Milky Way would only be a month old. The actual universe is 14 billion years old. First of all, is the month claim accurate? Does this mean that we know that something the size of the Milky Way can form in about a month? The Milky Way took a month to make?(the space of it) Where does inflation come into the equation?
Thanks
