I think the problem is that no matter how much we all like "why?" questions, for everyone there is a point where they simply accept that something exists because it exists. For me, whilst within the frame or reference of everything/reality/the universe/... the question for causes, origins, etc. makes perfect sense, I see no reason why to ask the same question in transcending this frame of reference in which these questions make sense.Thanks everyone for your responses. I'm getting the impression that alot of you think that questions about why reality exists to be, well, stupid or something. I don't understand why. To me, it seems perfectly natural to wonder about it.
But the more interesting question is: Does the existence of the existence of existence exist?That your primary metaphysical axiom is that existence exists,
That your primary metaphysical axiom is that existence exists, nature exists, and that it is not nessessary to go beyond this to any other metaphysical principle.
Just out of curiosity, if you don't believe that God is real, what do you believe governs reality? What's your theory? What is it that determines the rules of physics, the architecture of everything that is?
I think that physicality is more fundamental than consciousness, which is to say that physicality does not depend on consciousness for its existence, however, consciousness depends on physicality (on something physical) for its existence.
1) One the laws of thermodynamics and the observations on perpetual motion indicate a universe winding down. If the assertions that nature exists as your foundational metaphysical principles true, this would mean that either energy or matter would have to be eternal. However, these facts indicate that nature is not eternal. That, left to its own devices, it will subside to heat death. As far as my reading of Hawkins and others are concerned, the attempt to use an oscillating universe theory has been unsuccessful.
I take it from your Ayn Rand picture that you're talking about the primacy of existence as opposed to the primacy of consciousness?
Can you go into some detail here? How does energy transfer from a vacuum? If it is truly a vacuum, doesn't that imply that there is nothing there, and if a transfer happens, doesn't there either need to be something to "take" the transfer, or energy to be transferred? And, if this is true, does this discount heat death? Or is that still in effect?While the Second Law is a very good means to observe macroscopic systems; like all things Newtonian, quantum effects still triumph when the numbers and size get small. There are certain processes that transfer energy from the background of space which are purely known through quantum mechanics. These allow for energy transfer from a vacuum which can lead to the creation of new particles. This will continue no matter how old the universe gets. It's an utterly random process.
My contention here is that, despite the fact the universe will continue, the winding down of macroscopic systems seems to indicate that they were wound up. I understand this does not prove theism, but it does make it a reasonable place to begin exploring, since the random processes on a microscopic level never reverse the nature of entropy.Also, due to the nature of atoms and the fact that absolute zero is unattainable (via yet another thermodynamical law), the atoms will always be in some sort of motion no matter how long the universe goes on aging. The kinetic energy involved in their motion never disappears, though you might get systems of atoms with only a few nanoKelvin as a temperature, while systems are allowed to approach absolute zero, it is impossible to attain. This would violate Heisenberg's Uncertainty Principle, which I, for sake of some brevity, will not go into unless you wish for me to.
You can explain anything you want in as much depth as you want. This stuff doesn't bore me.Basically, energy and matter never disappear. This is in tune with the First Law of Thermodynamics. Of course, if you wished to get more in depth, we could leave Thermodynamics entirely and talk about solutions to the Friedmann equations or other things that suggest a universe that will keep on aging, keep on existing, and keep on possessing energy. It may be a one-time deal; but the laws that govern the universe will keep on governing it; no matter what happens.
Silenus said:Okay, I'm going to start by saying this to Lucretius. If you don't have time to explain things to me further, don't feel the need. You obviously can answer some questions I've always had about quantum theory from my amateur readings. If you feel its more appropriate to answer them over e-mail or message instead of forum that would be fine too. And if you're too busy, feel free to recommend books.

In fact, even at absolute zero (this is something I will learn in Q&M) a particle would have a residual energy. The reasons for this are unknown to me, but it comes out of some math and I'd wager a guess this is also due to the uncertainty principle.
So no perfect vacuum can exist.
What happens with the energy transfer is this: the vacuum can spontaneously give rise to particle/anti-particle pairs. This is such that energy is conserved because the particle and anti-particle annihilate one another and the sum energy lost is 0. We can observe the effects of these particles in terms of the Casimir Effect. The resonance energy (the energy a particle or vacuum has even at absolute zero) results in an inward push on, in the case of the Casimir Effect, two parallel plates standing very close together.
The main importance of this virtual particle pair production, I think, is in terms of the early history of the universe, when inflation took place. The expansion was in fact so rapid that the expansion of the universe pulled these particle pairs apart before they could even annihilate, resulting in the particles we see today. This would mean, in terms of energy conservation that gravitational energy is negative energy! A bizarre notion, and one I am currently reading about in Alan Guth's book.
I see where you are coming from. If the universe is heading towards greater and greater entropy, how could such a time have existed in which entropy = 0, without negative entropy proceeding it? Well, without touching on the "origin" of the fundamental forces (they are called fundamental for a reason), we can see that, assuming space and time exist ( I don't see how we could get anywhere if they didn't), the universe could have followed the process I described before. The energy for a gravitational field is negative, and a lot of negative potential energy must have been stored in the early universe when it was very tiny and dense (thus gravity would play a rather large roll). When inflation occured and this negative potential energy was released, the energy from the vacuum fluctuations (positive energy) could have been harnessed (this would imply the total energy is the universe might be zero), producing all the particles we see today. What led to inflation, you might ask? I'm no expert on inflation and in fact I'm reading Alan Guth's book for the second time now to try and wrestle with the concept. If you wish to know more, I would recommend his book, but be sure to do some research on a Higgs Field prior to your read, as things get pretty hairy after the first eight or so chapters.
Silenus said:No perfect vaccum exists due to law number three, and what we see as a vaccum is actually particules we can't sense because we observe particles in movement and, in a vaccum, their movement is undetectable. I think I get it.
Silenus said:I read this and I think I get it, but theories like this seem to indicate to me that exploring a theistic premise isn't untenable. Yes, I agree that one must realize that any intellectual search will lead to fundamentals that seem to stand on their own, but, the winding down of the universe indicated to me something outside of nature starting the clock. Also, i have trouble conceptualizing a fundamental principle that is bound by space-time. This is not what i hang my belief in God on, there are many things that contribute to it, both rational and experiential, but I think the two things I mentioned provide some starting points for explorations into theism.
Could you elaborate on what you mean by "Also, I have trouble conceptualizing a fundamental principle that is bound by space-time."?
The foundational principle would need to be outside of space-time because of the nature of movement and the fact of entropy. If a fundamental principle is bound in space-time, it still is bound by cause and effect and we are stuck with a set of infinite causes and no explination for rationality. Couple this with the other argument I put forward, and I start looking to Theism. Now, I understand the falsified thing. But the metaphysical principles science is based on cannot be falsified either. Science is based on metaphysics outside the laboratory and, to me, it becomes a search for what corresponds to what is out there. Yes there is a problem, because how do you know what corresponds to what is out there, unless you are the one out there over everything? But, I do think there are certain things that cannot be denied, rationality being one of them.
I would say the problem with jumping to theism by fear of an infinite causal loop is that you are being entirely arbitrary in postulating a being and putting at the start of the chain. In essence, not knowing and having the causal loop is a more rational choice than simply arbitrarily placing some supernatural force at the beginning without any justification other than "we don't currently know the answer." As for the assumptions upon which science is based; I'd say the justification for this lies in the findings of science. Science has been constructed such so that it takes evidences from the natural world and uses them to formulate theories about the natural world. The supernatural is left out because, while it may exist, there can be no evidence for it in the natural world. What problems exactly do you have with the assumptions that science makes then?
No one is positing a causal loop here though. We simply don't have the answers as to the earlier causes. It may be the case that under the extreme conditions present during the early seconds of our universe, that the Second Law is dwarfed by another process that acts to counteract what the Second Law achieves. The point is; our knowledge about this era of our universe is still in it's infancy. Coming to any sort of conclusions especially ones positing the supernatural are presumptuous.
Next you present the inductive fallacy. It is true that strictly speaking, one can never go from induction to deduction and therefore all universal statements are never absolutely justified. However, if we are to throw out induction; what then do we have left? Induction has proven itself (I say that in a non-logically rigorous way!) to be very accurate in the world. I base that claim on the fact that right now I am using a computer built from understanding electricity. I live in a dorm powered by electricity, that has heating. I have a fridge, etc. All of this has been achieved through science. Notice how none of these require explanation through divine intervention. It is only because we do not know what went on during the earliest period of our universe that you seek to place God there.
The point is, despite the fact that we have certain physical laws that seem to prevent certain things from occuring at the early stages of our universe; the fact is that things get rather strange during this era. Hell, we don't even know how general relativity works during this time because quantum mechanics is suddenly on an equal footing what makes you think we can come to any conclusion about entropy flow during such a time?
