There are probably not many people alive on this planet who can imagine what it might be like just before the Big Bang. I mean we have a rough, if not entirely accurate, idea of what the universe (or multiverse) is, and what it was like within a second or two after it went “bang”. We’re talking about all the baryonic matter and baryonic energy, dark matter and dark energy, and anti-matter and anti-energy, space and time, as well as anything else that might be hanging like mistletoe from the continuum of what is. Incidentally, there probably wasn’t any “bang” during the Big Bang since, as my father asked me when I was seven years old, if a tree falls in a forest and nobody was around to hear it, did it make a sound? There certainly wasn’t anyone around to hear the Big Bang.
Could another Big Bang happen in our universe? Hopefully not. That’s probably why they call the Big Bang a singularity, but then they call black holes singularities too and black holes are found in many different galaxies around the universe. One of the advantages of the multiverse theory is that you can have Big Bangs going off like firecrackers all over the place all of the time, but only one per universe.
So what caused the Big Bang? Before the Big Bang you had one big nothing. No matter, no energy, no space, and no time. Just potential, one humongous potential. How long did this nothing last? How big was this nothing? These last two questions have no meaning whatsoever. Like dividing by zero. I once heard a story about what happens to one of those old Friden mechanical calculating clunkers when you try to divide by zero. The arm just flies off, killing the student sitting next to you, and the machine falls apart. Needless-to-say we were forbidden from dividing by zero on our Fridens.
I just finished reading up on the Big Crunch (Contracting Universe) and Big Bounce (cyclical Bang then Crunch ad infinitum) theories of the universe. These theories have fallen into disfavor somewhat because they seem to defy the second law of thermodynamics, something about how they allow too much heat to build up between Bang-Crunch cycles. Now that humongous potential between the last Crunch and the next Bang might be made up of potential matter, potential energy, potential space, and potential time but, the way I see it, the heat from the second law of thermodynamics should be conserved from the Crunch heat to the Potential heat to the Bang heat, neither more nor less, but exactly the same.
Because it would make no sense to ask how long the time between Crunch and Bang was, I would conjecture that it took no time at all; that is, the Big Bang occurred immediately after the Big Crunch. It would also be rational to conclude that the Big Bang was caused by the Big Crunch. It was not only the sufficient cause, it was the only cause. As Sherlock Holmes said in The Sign of the Four, “when you have eliminated the impossible, whatever remains, however improbable, must be the truth”. At the time of the Big Bang there was nothing else besides the disappearing Cheshire Cat smile of the Big Crunch.
Maybe I should call my theory the Big Boing Theory. It has all the attributes of the Big Bounce Theory without the silliness of the official name. Besides, it reminds me of the similar sounding name of that stupid American television series about those three idiot-savants. Who knows? Maybe I’ll be able to sell the rights to a TV series about my theory. It might go viral like the sales of my latest sci-fi novel.
