So far we agree.No one should say that “there was a time when the Universe did not exist.” That is indeed an incoherent statement, primarily because the universe IS time but also space, so that they form a fabric and contain all matter and energy. That sum total of time, space, matter, and energy is the universe.
But it does, implictily. If you had said that “a finite time ago the Big Bang occurred, and the Universe assumed its current form” then there would be no implicit reference to the “before”.Rather, and more appropriately, I would affirm the statement, “A finite time ago, our universe came into existence.” This more accurate statement does not assume time before the universe. In fact, the initial moment of time, which we indicate using a singularity, marks the edge of spacetime so that space and time literally come into being in the immediately proceeding moment.
That is not accurate. It should say that “about 13.7 billion years ago the Big Bang happened”.This is the standard model among cosmologists, which is why you will often hear the universe being called 13.7 billion years old. That is the “finite time ago” I am referring to in the statement I affirm.
The usage of “always” also implies a time outside the Universe.You cannot rightly suggest that the universe has always existed because this would commit the fallacy of infinite regress. In an infinite time, all possibilities would be realized in our universe. There are several problems that this would create if true, but suffice it to say that an infinite of anything can never be realized in spacetime. despite what you seem to be suggesting. If our universe has always existed, then an infinite amount of events have already occurred, which is impossible.
Saying that the Universe is a “created being” already assumes the result which you wish to demonstrate. It is incorrect to assume the expected result as one of the premises. (***)
- You argue that the universe–that is, spacetime and the sum total of all matter and energy–simply exists and does not need a cause. I have shown already that in fact it does need a cause*, it did come into existence, and scientists know roughly how long ago it came into existence. Since the universe is a created being, it requires a cause.
Except I explicitly stated that the base assumption of the atheists is that the Universe is uncaused and “uncreated”.
- God exists outside of the universe–including spacetime. This is not simply an arbitrary assertion, but a necessary reality! Why? Because if God was bound by spacetime, or even just space or time, he could not be the cause of the universe, which has spacetime as a component. Something which is among the universe cannot cause the universe without committing the fallacy of begging the question.
I did not ask that. And I also agree that it would be an incoherent question, just like “What caused the Universe?” is an incoherent one.So God exists outside of the universe and because of that he really does not require a cause. For how can we speak of a cause outside the context of time? The terms “before,” “after,” “cause,” and “effect” only make sense within the context of time, just as you cannot go left without space to turn left within! Therefore, since these terms mean nothing outside of time, the question “What caused God?” is incoherent and thus negligible.
I did not say that the universe extended infinitely into the past, since the usage of “past” assumes an “absolute time”, and we both agree that time only exists within the universe.
- If the universe was not caused, so that it has always existed, then certain incoherences arise. For instance, in a universe which extends into the past ad infinitum, all events in the present have been realized…
The current form of the Universe. We can say nothing about the “before”, because the “before” would assume an “absolute time”.
- …You must realize that the standard model adopted by cosmologists places a singularity 13.7 billion years ago, representing the reality that the universe did not always exist and in fact came into existence at that time (t=0).
Refer back to (***) where you introduced this expected result as one of the premises.For these reasons, we understand that the universe requires, not only a cause…
Summing up: “The proposition that the Universe simply exists does not imply an infinite, absolute past” - which is the backbone of your argument. According to our best knowledge, matter/energy/momentum etc. cannot be created, nor destroyed. It is a basic principle, which cannot be “proven”, of course. Also causation (like space and time) cannot be defined “outside” the Universe.
I accept that is whole argument creates a “picture”, which cannot be “visualized”. We are unable to “visualize” a huge blob of STEM (space/time/enrgy/matter) which somehow “resides” in a “nothingness”. But visualizing something is not necessary to hold it true. We cannot visualize a hydrogen atom either. The first model suggested by Niels Bohr was a miniscule “solar system”. This “visual model” was discarded, and nothing really took its place. We are simply unable to attach a “normal world” picture to a hydrogen atom, or the totality of the Universe. It is regrettable, because we humans are highly visual beings. But the lack of a picture does not render it impossible.
