No, for two reasons:
1) In an oscillating universe, the age might be far more than 13.7 billion years.
2) I don't believe that the universe (i.e., physical reality) "began to exist." At t=0 (the first instant of time) physical reality existed. There is no "before" t=0, therefore it would be inaccurate to say that physical reality "began to exist" at that point in time, as if it had popped into existence out of nothing.
I gather you are maintaing then, that the universe is eternal.
This position cannont be scientifically or philosophically justified for several reasons:
1. The second Law of Thermodynamics states that the universe is running out of usable energy, like a car running on gas will eventually run out of gas. Since the universe is running down, it must have at one point,
began this process of entropy; just like at one point, there was a full tank of gas which began running out as soon as the engine began to use it.
2. Physicists John Barrow and Frank Tipler observe regarding the Big Bang:
"
At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the universe originated at such a singularity, we would truly have a creation out of nothing." (John Barrow and Frank Tipler,
The Anthropic Cosmological Principle (Oxford: Clarendon, 1986), 442.)
Therefore, it follows, that nothing material existed prior to the singularity, for it is the edge of physical space and time. It therefore represents not only the origin of all matter and energy, but also of physical space and time themselves.
Quentin Persifor Smith (born August 27, 1952 in Rhinebeck, New York) is an American contemporary philosopher, scholar and professor of philosophy at Western Michigan University in Kalamazoo, Michigan. He has worked in the philosophy of time, philosophy of language, philosophy of physics and philosophy of religion. Smith has published over 140 articles and of his published books, he has authored three, co-authored two, and co-authored and edited seven. He is an editor for Prometheus Books and was the chief editor for
Philo from 2001 to 2007.
He has this to say regarding the Big Bang event:
"
It belongs analytically to the consept of the cosmological singularity that it is not the effect of prior physical events. The defintition of a singularity...entails that it is impossible to extend the spacetime manifold beyond the singularity....This rules out the idea that the singularity is an effect of some natrual process." (Quentin Smith, "
The Uncaused Beginning of the Universe", in William Lane Craig and Quentin Smith,
Theism, Atheism, and Big Bang Cosmology (Oxford: Clarendon, 1993), 120.)
Sir Arthur Eddington also states regarding the beginning of the universe:
"
I feel almost an indignation that anyone should beleive in it - except myself." (Arthur Eddington,
The Expanding Universe (New York Macmillan, 1933), 124.)
And:
"
The beginning seems to present insuperable difficulties unless we agree to look on it as frankly supernatural." (Arthur Eddington,
The Expanding Universe (New York Macmillan, 1933), 178.)
Some attempts have been made at trying to offer a naturalistc explanation in light of the above. Namely, Stephen Hawking's quantum gravity theory.
In Hawking's theory, time is finite but does not have a beginning point or edge. Unfortunately for Hawking and any other detractor of creation, his model cannot be an accurate description of the universe.
Why?
Well for one reason, Hawking presupposes that the universe does not exist in "real" time, but "imaginary" time. In his equations, he uses imaginary numbers for the time coordinate, numbers like √-1.
Such numbers are mathematical devices that are completely void of physcial meaning.
In fact, Eddington in 1920 dispelled the veracity of such attempts at using imaginary numbers way before Hawking was even on the scene.
He states regarding these numbers and calculations:
"
it can scarcely be regarded as anything more than an analytical device." (Arthur Eddington,
Space, Time, and Gravitation reprint ed. (Cambridge: Cambridge University Press, 1987), 48.)
Imaginary time he says, was merely an illustrative tool, which :
"
certainly does not correspond to any physical reality." (Arthur Eddington,
Space, Time, and Gravitation reprint ed. (Cambridge: Cambridge University Press, 1987), 181.)
2. Philosophic reasoning tells us that an eternal universe could not exist for the simple fact that there could not have been an infinite number of days before today; otherwise today would never come.
By definition, an infinite can never be traversed - it has no beginning or end. But since we have arrived at today, it follows that there must only have been a finite number of moments before today.
Once again, even the great skeptic David Hume states:
"
The temporal world has a beginning. An infinite number of real parts of time, passing in succession and exhausted one after another, appears so evident a contradiction that no man, one should think, whose judgment is not corrupted, instead of being improved, by the sciences, would ever be able to admit it." (David Hume,
Enquiry Concerning Human Understanding, ed. Chas W. Hendel (New York: Liberal Arts, 1955), 165-66.)
So you see Mark, if you maintain, as you do, that the universe did not begin to exist, then you do so
inspite of the evidence, not
because of it.
Most people deny this simple truth because they have a
pre-commitment to naturalism. This pre-commitment prohibits them from
objectively examining the evidence and making objective inferences from it. If from the outset of your investigation, you presuppose the supernatural to be non-existent, then all of your findings are going to be interpreted in light of that view. This is not only bad science, but bad philosophy, for science is dependant upon philosophy.
Note also Mark, that you said this is your "
belief", and so it is for every other non-theist. You believe in what you do and in light of the evidence and arguments that show your position to be the least objective, you have great faith in these theories and hypotheses and beliefs. I dare say you excercise greater faith than us theists!
