Since an adiabatic system is within a surrounding the notion that it's the same as a closed system is highly suspicious. It has never been determined there is a scale at which an impenetrable surface actually exists.
Yes. You mentioned the notion of a universe with no surroundings, and that was what I was responding to. The absolute absence of an environment, including (and not except for) absolutely nothing. This speaks to the first law and also a perpetual universe. Without absolutely nothing there isn't...
If the universe has no surroundings then it is a closed system. It has no environment in which anything can exit into or enter from. Therefore, in that case the first law applies.
This is exactly what I'm getting at – what I'm trying to understand. I think it's fair to say that finite means a beginning and end. A measurable amount of anything. However, in math it appears as though infinite is not treated as its "not" or opposite. As I mentioned before, it's treated as a...
I'm first and foremost wanting to understand math's definitions of them in a more fundamental fashion i.e. as nouns and not adjectives. That being said I suppose we should stick with finity and infinity?
I'm troubled by what I think the 'community' considers them to be, but I'm not sure if I'm correct. It appears as though finite is thought to have both an end and a beginning, but is it true that infinite (infinity) is thought to only have no end? Is this accurate? If so, then it would seem like...
I see no correlation between a dimensionless point and a line although it appears that math has made one. I'm just a philosopher so it's quite possible that I've got it all wrong.
It seems as though any location along a line is always the same location. If a location has no size then it can't...
I'm speaking of the surface only. The ball is the accumulation of all that is inside the surface and it together with the surface would equal the universe I just described.
Allow me to introduce a related notion if I may.
Let's take the case of a single spherical universe with absolutely nothing else outside of it. If the sphere is perfect then the only location that anything can be within it, must be the absolute center. In other words, no matter where we are...
