      I don’t think the scientific method has produced a satisfactory answer to this question yet. We don’t know if the universe is finite or infinite. So far, energy appears to be conserved within the observable universe, but we don’t know how it got there in the first place.

      I think there are a lot of very smart people working on this problem, but the nature of the scientific method is that we will only ever be able test if their ideas or hypothesis are wrong, we can’t know for certain that an idea or hypothesis is correct.
