there are something like 30 universal constants all with precise values. the masses of certain particles, the strength of certain forces, etc. we've measured these to a degree of precision.
there is no known reason as to WHY they are set at the values they are.furthermore, it has been observed that, for a fair number of these constants, if the values were even slightly different from what they actually are, that the universe would be radically different. things like the inability of protons and neutrons to come together and form atoms, thus preventing any complex structure in the universe and life itself.the fact that the constants are so finely tuned has prompted religious nuts to proclaim this as clear evidence that a god exists, because 'he designed the universe so perfectly fine tuned so as to support complex structure and life.' if you are atheist, you reject this, and are left with the curious reality that our universe is indeed fine tuned to support complex structure and thus life. except you don't have an explanation, which is problematic.the idea is, at the time of the big bang, a very large number of parallel universes all exploded from a single point, each of these universes having a different combination of values for the universal constants. much like the way we live on earth not because it was designed for us but because we wouldn't have evolved elsewhere, we exist in this universe not because it was designed for us but because the other universes were unsuitable to support life. in this multiverse, life happens somewhere, and it happens where it is most likely: this universe, this planet.my theory extrapolates further on this: why only have multiple universes that merely tweak the values of fixed functions? why not have universes with a completely different set of functions entirely?thus, any possible universe that can exist, does exist.couple with the many worlds theory, and you have such an incredibly vast and most likely infinite number of universes, that everything you could conceivably imagine exists somewhere. that is inclusive of every work of fiction, every religion, every daydream and nightmare, everything. that is the nature of an infinite 'soup' of possibilities. something about an infinite number of monkeys and the works of shakespeare. even if experimentation has shown that the monkeys mostly produce pages consisting entirely of the letter 's.' which ironically mirrors the theory, as most of the universes would likewise be rather uninteresting, consisting of a blob of energy which the rules of that universe prevent from collapsing into interesting or complex structure.
If a universe is created in empty space and nobody's born in it does it exist?
This reminds me of a short story by Arthur C Clarke.
Two men are walking along a road, discussing the nature of the universe, and the infinite. One remarks that if the universe truly is infinite, then somewhere else, there exists a world exactly like their own, down to their own selves having this very conversation. In fact, there are an infinite number of such worlds - some only minutely different, others more so - for if the universe is infinite, then all possibilities must occur. One turns to the other and says that it is then possible that they might turn the next corner and find a tiger in their path, or something else even moreso unusual or unpleasant. The other turns back to him and replies that that notion is nonsense, and that if they don't find a tiger around the corner, he will consider the theory to be incorrect. They turn the corner, and that was the last thing that they ever did.On an infinite number of Earths, an infinite number of people meet an infinite number of tigers, either friendly, hostile, or indifferent, however improbable, for the first had spoken the truth. In an infinite universe, everything has to happen somewhere. It was bad luck, really. This world was one of those that lay closer to the realm of impossible - for what they met was really hungry, and even a tiger would have been a small morsel for any of its half-dozen gaping mouths.that's actually quite amusing DF. it is also in all likelihood a true story.
That's so full of shit I can smell it.
Fathom the set of all points on a 2D plane such that y=x. You should be thinking of a 45 degree line. It has infinitely many solutions, none of which involve a tiger, or y not being equal to x.our universe alone is build upon mathematics vastly deeper than 'x = y' and obviously any solutions prohibited by those rules would not occur. thankfully, df's example did not violate any of those rules. furthermore, my entry involves alternate universes based on entirely different sets of rules and not what those rules allow or disallow. in other words, what is your point.
i think these constants are "fine tuned" because they can only operate at that tuning. reality fluctuates. what works, sticks. naturally. did you know if u take all the positive mass in the universe and add it to all the negative "dark" energy, the sum comes to a very simple ZERO. all mass and existence is created by fluctuations of nothing. positive and negative mass. SCIENTIFIC PROOF that something CAN come from nothing.
Well, they are still working on the "dark matter" concept DSG. Last I heard, the universe was only about 5% matter and the rest was anti-matter.
What happened to your 3-liners?
You have become to mature.
