AI Thread Summary
The discussion explores the relationship between stuff, space, and motion in the universe, proposing that defining "stuff" requires distinguishing it from "space." It suggests that motion necessitates both stuff and space, and that both are forms of energy capable of transformation. The idea is presented that space might be a form of energy itself, especially in the quantum realm where stuff can seemingly appear and disappear. However, the conversation highlights the importance of time, arguing that without considering time, the movement of stuff in space is limited. Ultimately, the discussion raises questions about the nature of space and time in the context of the universe's structure.

Suppose one categorizes the universe as composed of only stuff, space, and motion.

It seems that to define stuff one needs to identify something that stuff is not.

Let's assume that space is not stuff and thereby allow a definition of both stuff and space.

Now, let's throw in the common observation that stuff moves in space and further that there seems to be no way to totally prevent it from moving in space. It seems reasonable that stuff should need space to move and that motion needs both stuff and space to exist.

Another common observation is that there are many sub-types of stuff and a common opinion that these subtypes can and do under certain conditions transform from one subtype to another.

I think, it is commonly conceded that both stuff and motion are a form of energy and can and do transform into the other under certain conditions. If this is true then that seems to put space in the do little position of not being able to convert into stuff.

In the quantum environment it seems that stuff can appear and disappear, as if, by magic. But, what if it it is really transforming into space? If so, that would seem to make the argument that space is just another form of energy.

It would also seem to make for a harmonious universe.

What do you see as the pro and con issues concerning this perspective?

Well, you've forgotten to account for time. Sure, stuff needs space to move around in, but if we're all stuck in the same moment of time, it's unlikely to be going very far.
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
