No, I am not, and I don't see how you got that out of what you were responding to.
Perhaps it was the observation that the universe may be oscillating. This does not say anything about whether the universe is eternal or not. An oscillating universe could be thought to have undergone either an infinite number of oscillations or a finite number. So, it could be thought to have an infinite past or a finite past. I lean towards the view that its past is finite.
I don't see how you could get that out of my other point, where I mention "t=0". Perhaps I could have been clearer, but "t=0" is my way of referring to the first instant of time/change.
Incidentally, while I don't trust your scientific arguments for a finite universe, I agree with the following:
This is precisely why I reject the idea of an infinite universe. Incidentally, that doesn't mean that I take Stephen Hawking's precise views, and I don't know why you even brought him up since I didn't mention him at all.
You are making one critical mistake. A beginning to time doesn't imply that the universe began to exist. It suggests that time/change had a start.
It is my view, which is in no way contradicted by scientific evidence, that the universe (i.e. physical reality) did not begin to exist, in the sense of popping into existence out of nothing. Rather, change had its start a finite "time" ago. Physical reality existed at the beginning of change, and so there was no "nothingness" that had preceded it, or ever a "time" in which no-thing had existed.
So, you are presenting a false alternative -- either the universe popped into existence out of nothing, or it was created by something that wasn't the universe. (Your approach seems to be "If I disprove option one, you must accept option two", a classic but flawed debate tactic.) I'm presenting option three as an alternative to your option two.Not all beliefs are alike. I have also stated that this is a philosophical conclusion that I have drawn, held tentatively since I can't prove it directly on empirical grounds. Is that what you are calling "faith"? If so, it is a heavily watered down version of the concept.
I don't have to have faith to see how weak your arguments are, or that you seem to misunderstand my position.
You may dare to say whatever you like, but statements like this are entirely gratuitous posturing. It is not a beautiful trait of character. It's just a way of trying to put others down. I have to imagine that you are doing this for the "audience" because you believe that putting others down with such dramatic language makes for good theater, but you should reflect on what you are doing for your own sake.

The absolute origin of the universe, of all matter and energy, even of physical space and time themselves, in the Big Bang singularity contradicts the perennial naturalistic assumption that the universe has always existed. One after another, models designed to avert the initial cosmological singularity (the Steady State model, the
Oscillating model, Vacuum Fluctuation models) have come and gone. Current quantum gravity models, such as the Hartle-Hawking model and the Vilenkin model, must appeal to the physically unintelligible and metaphysically dubious device of "imaginary time" to avoid the universe's beginning.
Mark, your position is based upon a view found within the steady state theoretical models of the universe. The name of this particular model you espouse is called the "
Oscillating Model".
In the 60's and 70's, some cosmologists suggested that by denying the Standard Model's conclusions that the universe is largely the same in every direction, one might be able to come up with an Oscillating Model of the universe and thereby avoid the absolute beginning predicted by the Standard Model.
The theory is that
if the internal gravitational pull of the mass of the universe were able to overcome the force of it's expansion, then the expansion
could be reversed into a cosmic contraction of a "Big Crunch".
If the matter of the universe were not evenly distributed, then the collapsing universe
might not coalesce at a point, but quantities of matter
might pass by one another, so that the universe
would appear to bounce back from the contraction into a new expansion phase.
If this process could be repeated indefinitely, then an absolute beginning of the universe
might be avoided. See fig. below.
In (a), each expansion phase is preceded and succeeded by a contraction phase, so that the universe in concertina-like fashion exists beginninglessly and endlessly.
Such a theory is
extraordinarily speculative, and has been all but abandoned by the scientific community.
In fact Mark, im quite surprised that you espouse this particular view since it has been abandoned by honest cosmologists and physicists since the 70's.
In 1970, Roger Penrose and Stephen Hawking's formulation of the Singularity Theorems which bear their names signaled the death of the Oscillating Model.
The theorems state that under very generalized conditions, an initial cosmological singularity is
inevitable, even for theoretical inhomogeneous universes.
Hawking, regarding the findings in the Hawking-Penrose Singularity Theorems states that they:
"led to the abandonment of attempts (mainly by Russians) to argue that there was a previous contracting phase and a non-singular bounce into expansion. Instead almost everyone now believes that the universe, and time itself, had a beginning at the big bang." (Stephen Hawking and Roger Penrose,
The Nature of Space and Time, The Isaac Newton Institute Series of Lectures (Princeton, N.J.: Princeton University Press, 1996), 20.)
Secondly Mark, there is no known physics which could cause a collapsing universe to "bounce back" to a new expansion. This is purely imaginitive.
Thirdly, attempts by observational astronomers to discover the mass density
sufficient to generate the gravitational attraction required to
halt and reverse the expansion continually came up short.
In 1998 astronomical teams from Yale, Princeton, the Lawrence Berkeley National Laboratory, and the Harvard-Smithsonian Astrophysics Institute gave a report to the American Astronomical Society that their tests showed that "the universe will expand forever". (Associated Press News Release, January 9, 1998)
In fact the question of the universe's density is no longer even relevant. Why? Because observations of the red-shifts of supernovae indicate that the rate of cosmic expansion is actually accelerating! Even theoretical high density universes would more than likely expand forever. Therefore, a potentially infinite future is no longer the privileged prerogative of a low density universe.
Recent information gathered from the (WMAP) probe indicate that:
"For the theory that fits our data, the universe will expand forever."

So you see Mark, your position is simply unscientific, ungrounded, baseless, and at best highly speculative; if indeed this is what you maintain as being the best explanation of the cosmos.
It also unnecessarily multiplies causes and violates the principle known as Ockhams' Razor when compared side by side with the Design Hypothesis.
Those who maintain this view, as well as the other one's out there, do so inspite of the evidence, not because of it.
