During the pandemic I have been pulling off old books from my shelf that I have never actually read, so I decided to give "In the Beginning" a try.
Nearly 30 years ago, Gribbin produced an excellently written book ,as usual, this time on cosmology and the origins of life. There are some very good explanations of astronomical topics, the cosmic microwave background and so on, but the book is very much out of date (the edition I read was from 1993) and the assertions about the Earth, Galaxy and Universe being literally alive (albeit no claim of them being conscious) are, in my book at least, sensationalistic and completely indefensible. As far as I can tell, the events Gribbin attributes to "evolution" (in the sense that life forms evolve) are completely physical and bear no more evidence of life than eruption of a geyser or the formation of a crystal lattice. But do keep in mind that it is an "old" book and Gribbin may well have altered his viewpoint.
In general, even if the claim of the Universe being "alive" were realistic, it does not broach the subject of ultimate origin, as to why the physical laws are such as they are, except the common conjecture that there may be an infinitude of universe, each with different laws, and we happen to have one where life is possible.
The is no mention that I could see of a reason that there are an infinitude of universes, which would be the next obvious question. I am *not* suggesting Intelligent Design or any intervention of a deity, but the question of "Why is there something rather than nothing" (first articulated by Leibnitz, I think) is all that Gribbin attempts to answer. Basically, as with other cosmologists and physicists, he says that they Universe may have come from nothing, literally, as a separation of negative energy (e.g., gravity) and positive energy (matter) exactly cancel each other out, leaving.... nothing.
But this only describes a potential process, saying nothing at all as to why the process is even possible. This, in my opinion, is the ultimate question, and one that probably can not be answered to the satisfaction of limited human mind.
Overall the level of writing of "In the Beginning" is topnotch and the book was good in its day for the astronomical descriptions it gives. But today there are many other, more current, choices.
