Here is a two-part replay:
@Gregolas, It was spawned from my current WIP, but I am very much a person who indulges in theory. Thus, the question, as posed, was meant to be theoretical. In it, I specifically mention Understanding due to the WIP background, but I spent the same amount of time considering each Type in the Physics Class before posting. I haven't thought about the Universe class, yet.
Now, for my current WIP, I think @actingpower was right on the money. Thank you!
