    I was posting a response to you when that thread closed. Here it is (500 characters at a time):
    If that is a philosophical definition, as you claim, then what is the physics or physical sciences definition?

    I am not presuming any so-called perfect information at all. I am also not sticking to that definition at all. Why did you presume that I am not seeing the difference between a philosophical discussion and a scientific one?

    you appear to be taking my open questions, always asked from an open perspective, completely off track and off topic. Physics and deals with what is measurable and what is observable. So, what is the agreed upon and accepted word or term here for 'that', which all matter, space, and energy considered to be as a whole can or could be observed and measured? If the word and term 'Universe' does not suffice, then what word or term does?

    It really depends on what you are trying to measure, observe, or analyze. As you may have noticed in the Einstein example above, you get to improvise. In general, a Physicist will look at the experimental results, perhaps find some patterns, and form some ideas. Then they will find a way to communicate those ideas. So it's the subject matter that precedes the definition.

    There are terms that are pretty fixed. For example, if you talk about a "Newtonian universe", most will immediate envision a 3D Cartesian coordinate system with Euclidean geometry and very simple and deterministic physics. You can say "Schwarzschild black hole" and every knows that's the model you get with General Relativity and no angular momentum. Those terms have very specified stories behind them. "Universe" isn't one of them.
