Is there no end to all of this? Just kidding.
First of all, according to modern physics, time and space are inter-related. According to quantum physics, the universe is finite, as there is a finite amount of particals, even at the sub-atomic level.
There was some discussion about not being able to traverse infinity. In truth, infinity is NOT a number, it is an abstract concept. Furthermore, there are actually different levels of infinity, referred to by thier “cardinality”. For instance, the set of natural numbers has the same cardinality as the set of integers, or even the set of rational numbers (fractions). The proof for such things is based on the idea that one can generate a mapping from one set of numbers to another. So we can have infinite, and discrete. According to quantum mechanics, the universe is finite and discrete. But the set of real numbers, for example, is of an ever higher level of infinity, or cardinality. A consequence of this is that the probability of picking any one number in the real number line between 0 and 1 is zero.
I think of God as infinite (and of the highest cardinality), and of our finite existense as having zero probability, except for Gods decision to deliberately create our universe, and thus us. To God, our finite existense is very small, and thus well within His capacity to comprehend fully. We, on the other hand, are unable to fully comprehend God. God is NOT bound time, dimension, space, or any known laws. As God is the creator of our universe, and our universe is relatively simple to Him, WE are bound by all laws created by HIM.
Theoretical physicist and Catholics have one thing in common. We both realize that we have to accept the concept of mysteries, i.e., there are somethings that we can never know. God does not have such limitations. To say that God is great is an understatement. How great He is is truly beyond our realm of comprehension.
When someone ask me for proof of God, I say look around. God gave us all a good home that we call Earth. From this, It’s now what we make of it. We are suppose to be Gods children - His family. We have to realize this, and start acting like His family. If we did, then there would not be much suffering, or injustice in this world.
God bless.
