I am interested in whether the universe— and for that matter time and space— is finite, and enjoy reading articles on the topic. Yes it does seem scientific opinion is changing with new knowledge and that the verdict, or even general consensus, is not yet out.

Then the metaphysical implications— I’m sure this will still be a hot topic decades if not centuries from now.
