I think he is arguing that if you have a lottery with an infinite number of combinations , there is only 1 number that corresponds to nothingness (the empty set). The chances of picking that number among all the others is essentially 0, so that isn't going to happen. I guess he's trying to say that the universe exists because existence is far more probable than non-existence.

Why do you think the question doesn't make sense?

Right, but that's a massive assumption. I mean, nothing in our knowledge dictates that anything similar to a lottery would be at work. My objection is thus the same as that which naturalplastic puts forward. Even if there are a billion different somethings, nothing that we know of would dictate the relative probabilities, so to assume that this is entirely random is not a justified assumption.

First of all: Kon- why are you refering to yourself in the third person?
You ARE the OP ( the 'origninal poster' in case you didnt know).

Second we are all trying to say the same thing : that you are assuming that all possibilities are equally likely.

Your assuming that Got is sitting in front of a roulette wheel with a million numbers on it. One number is for an empty universe, and each of the others is for some crazy variation on our universe ( except the one that is for our universe as it is).

He spun this wheel, and where it landed thats what we got.

But that rests on the assumption that each outcome is equally likely.

Maybe god is lazy and would rather not make matter. So he gives the roulette wheel , not just one, but 50 percent of the numbers the prize of an empty universe. So the "empty set" isnt just one chance in the billion choices, but is 500 million out of the billion possible universes.

How do you know god parses out the choices evenly? Thats a huge assumption.

And ofcourse Im using the word "god" metaphorically.

The THING is...topic

I cannot imagine nothingness. I tried when I was a kid, in a pitch dark, noiseless closet, but even then THAT was SOMEthing.

Much ado about nothingness.

We forget how the universe we live is in fact little more than a void consisting of only smidgen more than nothing. A hiccup in a vacuum.

First consider how far apart stars from each other, and then within our solar system how far apart planets are from each other- you then realize how little solid matter there is compared to the vast amounts of empty space in the large scale of the universe.

Then you look around at the "solid" matter around us that you and I and the objects around us on the earth's surface are made of. You realize that even this 'solid' matter isnt solid at all.

The distances between atoms in your body are huge compared to the size of the atoms themselves.

Then you look at each atom. The atoms themselves are almost entirely empty space.

You have a halo of light wieght electrons as the outer shell of an atom.

But the heavy nucleas at the center is tiny- comparable to the distances between planets in the solar system- relative the size of the subatomic particles.

So on every level matter is made mostly of nothing.

Thats the universe we already live in.

So an totally empty universe is NOT much different from what we already have.

There should be nothing and yet there is something instead, which is truly bizarre. The ability to contemplate this itself is even more bizarre.

Apparently everything comes from Nothing. Strange.

Even empty space isn't really "empty". Think about how electrons are spread out in wavefunctions in the atom. Think about the "quantum vacuum", etc. So, in a sense, one can argue that true emptiness/nothingness doesn't exist in our universe.

42 is not the Answer to the Ultimate Question - it's the Answer to the Ultimate Question of Life, the Universe, and Everything. Not quite the same thing. :)

One of the posts started off, "Assuming there is a God..." That's where you lost me. You're starting off by assuming your conclusion. You may well believe there is a God (I do), but you cannot logically prove His existence with any argument that starts off by assuming it.

As for your original argument, Kon, if the Many-Worlds hypothesis is correct, then there would be an infinite number of universes. Of these, there would be an infinitely-large subset of universes in which the laws of physics, following the Big Bang, did not support the existence of anything, and a similarly infinite subset of universes in which there never was a Bang to begin with - empty universes. There are also infinite universes in which there is something, one of which is the universe we occupy now.

Why do we occupy a universe of something? Because if there were nothing here, that "nothing" would include us - that is to say, we wouldn't be there to comment on it. This is called the Anthropic Principle. It comes in two flavors - the Weak Anthropic Principle says that we know this universe exists because we are in it, while the Strong Anthropic Priniciple holds that the only universe that exists is one which has observers - that a universe cannot exist without life to note its existence. (I don't follow the logic of the second argument; I personally think it's just another way to try to slide religion into science by the back door.)

The Anthropic Principle basically says nothing more than if a person were to say, "I can observe this because this is here" and as such serves as a tool to ignore thoughts of "why is this here?". Yes, life wouldn't be here if all the conditions weren't within acceptable parameters, however with each independent parameter being within acceptable values correct for life to exist the probability of such happening on its own decreases. Even with every item necessary for life to exist on a planet though, such is not necessarily sufficient to cause life, but for those with faith in luck they can go play at casinos and expect to beat the house.

if God or the concept of a God is the ultimate non-physical reality, and this God also exists, then there must be a non-physical reality.

Perhaps you should watch this item. It might change your mind.

you're saying that (a) There is infinite kind of something.
i can not see that there can be an infinite amount of any manifestation because otherwise it would fill the universe to a density that is uncontainable by the boundaries of reality.

naturalplastic wrote:

there is no "kind" of nothing. nothing does not exist.

naturalplastic wrote:
The probability of any kind of universe is about the same.
yes.

naturalplastic wrote:
That probability is the reciprocal of infinity.
the reciprocal of infinity is "zero". "zero" and "infinity" are opposite concepts, and they both do not exist because they cancel each other out.


naturalplastic wrote:
So the probabllity that the universe would be nothing is this microscopic number a notch above zero.

there is no probability that the universe could be "nothing" because the universe, whatever it is, exists, and "nothing" does not.

naturalplastic wrote:
Being exactly the way it is just as unlikely as it being a void.
"anything" being a "void" (nothing) is ultimately impossible even when quantum consideration is exhausted.

The 20th century philosopher Alan Watts pointed out that most people take for granted that we exist, when it is in fact quite an odd situation. Here we are, egos trapped inside a bag of skin, living on this ball of rock orbiting a spherical fire. Watts quoted G.K. Chesterton to illustrate this point:

"It is a special kind of enlightenment to have this feeling that the usual, the way things normally are, is odd—uncanny and highly improbable. G. K. Chesterton once said that it is one thing to be amazed at a gorgon or a griffin, creatures which do not exist; but it is quite another and much higher thing to be amazed at a rhinoceros or a giraffe, creatures which do exist and look as if they don't."
— Chapter I, The Book: On the Taboo Against Knowing Who You Are, Alan Watts, 1966
