You have yet to present a paradox or problem.
And I am not sure what you are stumped about
If the Hindus reconciled the problem 2,000 years ago then why are you not able to tell us exactly what the problem is?
I am not stumped. I am quite happy with an infinite universe*.
The problem hinges on this "finite but unbounded" statement, now I don't know how the Hindus arrived at the problem. But it was probably with a similar phrase.
I have already stated the problem twice;
1;
1; Does the universe continue into infinity?
If the answer is yes, then there is no "beyond the universe"
2; Or is the universe finite?
If the answer is yes, I would argue;
1; there is a beyond the universe or
2; its turtles all the way down(which is equivalent to a yes to question 1).
2;
1; Does the universe continue into infinity?
(hence an infinity relating to matter).
2; Or is the universe finite?
(if finite it can be defined as an "object")
If there is one object, why not two or three or an infinite number?
turtles all the way down.
Both these arguments hinge on the issue of can a finite thing be described as an object, ie have theoretical boundary.
If a finite thing can have no theoretical boundary then it must be; unbounded=unboundedness=infinity.
*This is not entirely true, but to continue with this line of reasoning I am adopting the position of an infinite universe.
