For thousands of years people have been wondering whether there is a beginning and end of time, whether space has any limits, and can matter be divided into smaller and smaller particles indefinitely.

But another question is whether causality itself has any limits. If you look at a certain thing or phenomena, for the most part, it is so because of something – it has an underlying cause. And that something is so because of something else – another cause – and so on…

Is it possible to arrive at something which is the last cause and there is nothing beyond it? It’s like considering the universe to be finite, but if it is so, what is it enclosed into? And if there are many other universes contained in some superior multiverse, what is it enclosed into and so on…

Can something be just by itself and have nothing that caused it, itself being its own cause?

And if causality is infinite could we ever comprehend it because it would take a mind with an infinite conceptual ability, whereas our minds are, apparently, limited in their conceptual ability – can conceptual and logical causality be infinite?

Is God the ultimate cause of an infinite causality? – this statement seems to be paradoxical.

If there are rules and laws of things, where did they come from, do they have superior laws and so on?
