MAnewbie,
My take on the BB and its relation to QM is based on books I have read. Although I haven't checked on many of the sources provided by them, they are thoroughly sourced throughout, and are scientifically accepted as reliable. I have read many books on QM and it interests me greatly, so based on what I know about QM, the BB theory I believe to be acurate is quite consistant with everything I know.
Once again, I will not go into the same detail as that of the Authors I have read from, simply because I do not have equal dexterity with my words, and I might confuse you and deter my efforts.
If you still desire more detail I'm afraid I will have to point you into the direction of a Book store, with some Book names.
So to explain to you with more detail than before;
• The universe exists.
That much everyone will agree on. We observe its existance, and we perceive it. If one does not assume this as fact then the discussion is pointless.
• The universe had an origin
Many people will suggest that the universe could maybe have existed for an infinite time, where the causes can regress back infinitely. Now this may be an appealing idea, but it is simply not scientifically sound.
We know that the universe had an origin in regards to our current time. It was 'born' some 15 billion years ago (in the Big Bang), which is widely accepted, since the primeval explosion is clearly detectable. We know this as the universe is still expanding, and is filled with an afterglow of radiant heat.
• Every effect/action, has a cause/reaction.
From a young age, we all believe in cause and effect, as we see it happen every day. Nothing happens for no reason. Things are not random. Physics has many laws to support this as well.
Thus, we draw another conclusion;
• The origin of the Universe (the BB) is the result/cause/reaction of something.
In otherwords "What happened before the Big Bang ?" Something must have caused it.
• The origin of Time did not occur before the origin of the Universe.
It was Albert Einstein who taught us that time and space is not merely an arena in which the universe plays out, but part of the physical universe. As physical entities, time and space can change as a result of gravitational processes. Gravitational theory predicts that under the extreme conditions that prevailed in the early universe, space and time may have been so distorted that there existed a boundary, or "singularity," at which the distortion of space-time was infinite, and therefore through which space and time cannot have continued. Thus, physics predicts that time was indeed bounded in the past. It did not stretch back for all eternity.
• Thus the question "What happened before the Big Bang" is meaningless.
Now based on what we know about the nature of time and space, we believe that time itself did not exist before the universe itself. The origin of the universe was not simply the sudden appearance of matter in an eternally pre-existing void, but the coming into being of time itself. Time began with the cosmic origin. There was no "before," no endless ocean of time for physical process, to wear itself out in infinite preparation. This does not solve the problem though. Rendering the previous question meaningless, just generates a new one.
• Instead, a new (and more specific) question arises. "Why should time suddenly 'switch on'?"
So, what actually caused time to suddenly spawn ? This is where QM comes into the picture. There are physical events which do not have well-defined causes in the manner of the everyday world. These events belong to a weird branch of scientific inquiry called quantum physics.
Mostly, quantum events occur at the atomic level; we don't experience them in daily life. On the scale of atoms and molecules, the usual law of cause and effect are suspended. The law is replaced by a sort of anarchy or chaos, and things happen spontaneously-for no particular reason. Particles of matter may simply pop into existence without warning, and then equally abruptly disappear again. Or a particle in one place may suddenly materialize in another place, or reverse its direction of motion. Again, these are real effects occurring on an atomic scale, and they can be demonstrated experimentally.*
A typical quantum process is the decay of a radioactive nucleus. If you ask why a given nucleus decayed at one particular moment rather than some other, there is no answer. The event "just happened" at that moment, that's all. You cannot predict these occurrences. All you can do is give the probability-there is a fifty-fifty chance that a given nucleus will decay in, say, one hour. This uncertainty is not simply a result of our ignorance of all the little forces and influences that try to make the nucleus decay; it is inherent in nature itself, a basic part of quantum reality.
The lesson of quantum physics is this: Something that "just happens" need not actually violate the laws of physics. The abrupt and uncaused appearance of something can occur within the scope of scientific law, once quantum laws have been taken into account. Nature apparently has the capacity for genuine spontaneity.
It is, of course, a big step from the spontaneous and uncaused appearance of a subatomic particle-something that is routinely observed in particle accelerators-to the spontaneous and uncaused appearance of the universe. But the loophole is there. If, as astronomers believe, the primeval universe was compressed to a very small size, then quantum effects must have once been important on a cosmic scale. Even if we don't have a precise idea of exactly what took place at the beginning, we can at least see that the origin of the universe from nothing need not be unlawful or unnatural or unscientific. In short, it need not have been a supernatural event.
• Occams Razor states that the theory with least assumptions is the most correct.
The theory that the BB, along with time itself, was a result of a Quantem Phenomenon requires less assumptions than any other.
• Thus, the BB, (and thus the universe) tunnelled itself into existance.
So there you have it
*Thermodynamic laws are not violated when particles of matter appear into existance.
"Energy cannot be created or destroyed" actually reads "the total energy of the universe cannot be increased, nor decreased"
When one particle appears (increase in positive energy) it follows that there is an increase in negative energy somewhere else. This much we can confirm through Quantem experiments.
Which leads to the eventual conclusion that the total energy in the universe has never changed, regardless of the huge mass of matter in the universe that we know does exists.
I will go into this with more detail if you desire, but for now I will leave it at that. Only 1 topic at a time I think will benefit the discussion. I am sure you agree.
