If the beginning of the universe marked the beginning of time then whatever caused the universe to exist, exists outside of time and therefore is infinite.
Unless you have a time machine, this is completely unprovable and is based on a truckload of assumptions. Right here is where everything below this builds up way too high while having a very weak (arguably non-existant) foundation.
If I had a time machine I could only go back as far as the point where the dimensions of time began to exist. The beginning of the universe. TIME began to exist at the time the universe came to exist therefore time did NOT exist before the universe. If time did not exist then whatever was before the universe was infinite.
Whether you want to say that that cause was God or go with the mother universe theory which makes some unobservable untestable unknowable universe infinite and churns out many universes, the FACT is that whatever the causal agent is IS infinite and that's science, not religion.
A scientific hypothesis must be testable. For a hypothesis to be incorporated into a theory or turned into a law, it must be testable by experimentation or observation. If it is not testable, it remains only speculation.
This is far from science or religion. That's just a speculation with a obvious philosophy. Humans can't grasp the idea of infinite, but that does not mean that it is, without uncertainty, infinite. But there's absolutely no reason to sprinkle the christian god ontop of this (the link) to work in an agenda. Thus the whole "Can't prove it? Then it was my god!" I keep noticing with people here.
Most scientists agree that time began to exist when the universe began to exist (no religion involved) That hypotheses has been tested and incorporated into a theory. It isn't speculation. And I quoted a line that spoke of NON religious scientists. Therefore I did not use my link to sprinkle God on top of anything. I didn't even try to prove anything about God with my post. I simply showed how saying nothing can be infinite is not even a statement made by the prominent atheist scientists!
What isn't science is asserting to know with proof, WHAT caused the big bang because science has no way to test it. No matter what a person believes beyond the big bang is a matter of speculation/faith. But if we can know that time began to exist, then we can make a logical assumption that before time began, whatever there was had NO BEGINNING AND NO CREATOR.
Seriously Falconer, if you didn't have such a problem where my sources are concerned, I don't think you would even have disagreed with what I said. If you do disagree, then please explain to me how something can be bound by time and the laws of cause and effect before it even began to exist? Instead of rolling your eyes at my link, answer the issue that is in question??
But don't look to Stephen Hawking George Ellis or Roger Penrose because they are the ones who tested the theory that time didn't exist until the big bang. So I'm pretty sure they are not ridiculous enough to turn around and say that whatever was before our universe isn't infinite. As a matter of fact I KNOW they wouldn't because the same ones are the ones who threw the idea out there for the multi verse idea. So THEY do not believe that everything requires a creator. Which means that the buck stops with something that is eternal.
