You're saying that there should be such a thing as a "proper scientific conclusion" to this meme about a video game physics engine? The only definition of these portals that we have to work with is the definition in the Portal physics engine. There is no definition of anything that behaves like these portals in the scientific study of physics. It is meaningless to try to draw a scientific conclusion about something that does not have a scientific definition.

Oopsie again. Try reading what was written.
