If I place a circle such as a ring of gold in the vacuum of space would that make it eternal? The circle has no beginning and no end.
It has no beginning or end once you start moving along it, but you have to start that movement somewhere, which means there is a beginning to the infinite path.
The is the problem with people who believe that the universe is a self-creating loop. That doesn’t work. Even if the universe ends and creates itself again, without an initial act of creation the cycle could never begin.
Also, you place the circle.
#1 - You place it, meaning that prior to its placement it wasn’t there, meaning it isn’t eternal.
#2 - It’s a gold ring. Gold is a physical element, which was created, and therefore not eternal.
#3 - The vacuum of space is still a physical quantity. It lacks matter, but still has dimension. Given that it is physical in nature, it was therefore created, and is therefore not eternal.
Nothing in the scope of our universe is eternal. The universe is not eternal, and nothing within it is eternal. Everything in our universe is governed, to some degree, by
at least time, and most things are governed by far more dimensions and properties than that. Time is a property of physical existence, with a finite beginning. Therefore, the most anything in the whole of creation can be is infinite, it cannot be eternal by virtue of having a beginning.
Like I said before, you won’t actually be able to
comprehend eternity. We can imagine a line going far back and far forward from our current position, infinite in either direction if you like, but that understanding is still limited in that there is a specific reference point form which we are viewing the line. There is a start to the forward, and a start to the back. It is therefore not an eternal line, just an infinitely long one. Even when we’re dead, if we make it to Heaven, we won’t be able to comprehend God’s eternal nature. We’ll probably be able to understand it better, but it is simply outside the scope of our capacity to comprehend it in its entirety.
