I don't see how a flat smooth manifold would not be infinite (although perhaps that is a failure of my imagination). Maybe you refer to a non-smooth model? Could you give an example of such a model embedded in Rⁿ?

If the time component of space-time is infinite, then indeed the universe must be infinite even if the space component is finite every step of the way. Although, then the space component could be potentially infinite.

What do current theories have to say about any resolution to this question? The visible universe might be finite, but that says nothing about the totality. Should we include the Multiverse in this discussion (if there are many worlds)? What about the nature of quantum foam? Could that have a...

The presence or absence of a gravitational potential field has virtually no effect on the progress of nuclear reactions, because the gravitational force is so many times weaker than nuclear forces that cause an explosion and the electrostatic forces that hold the device together.

Maybe... That which has inertia? The nature of matter is determined by context, e.g., the Copenhagen interpretation.
