The goal of elementary particle physics is to answer that question. Our current paradigm includes various possibilities. The simplest one (and that of our best model, which is incredibly accurate) is that there exist truly elementary point particles which cannot be divided further. So they consist only of themselves, if you want..
So then a quark consists of a quark, as far as the current paradigm is concerned. Some would say it's substructure consists of nothing
I think you may be a little confused about the concept of coordinate system. It's just an arbitrary set of labels for points. You can put the origin wherever you choose, regardless of where you are..
My point here was, when someone says and I quote
"This ignores the fact that a point has a location in space and so contains information. Information is not nothing."
and I say
"The location information that a point contains is relative to whose view point.
Ours, inside space or outside space?"
and then you say
"I don't understand the question"
and then I say
"what I am asking is, if you are for example on Mars or 3000 light years away, would your co-ordinate system's point of origin be the same?
ie x,y,z or x1,y1,z1"
and then you say
"I think you may be a little confused about the concept of coordinate system. It's just an arbitrary set of labels for points. You can put the origin wherever you choose, regardless of where you are."
I am not confused about co-ordinate systems, I know that the point of origin can be anywhere.
However,if the point as some would say contains information of location, my question is which co-ordinate system would it be, and if the point of origin moved would it update its information. If not, then how could the point hold its location information.
In physics we often include time in the specification of points. Such a thing can't move, since it exists only at an instant of time. A point particle, as time passes, sweeps out a line of such points..
This line of points. What do they consist of? Particles? Nothing? What?
I don't think I explained that very well. The point is, you have to be very careful how you define things. There is a valid sense in which if you built up your collection the way you describe the football collection would always be larger in volume. But you cannot simply compare infinities without knowing how you arrived at them. Once both are volumes are infinite, they can no longer be compared without the information about how you got there. This is called taking a "limit" in mathematics.
This is what my argument is about about the 1 cubic metre of golfballs and 100 cubic metres of footballs. When you get to infinity, which you never do, the golfball sets volume is always is smaller because the volumes were different when you started.
That should be obvious, since we could also arrive at infinite volume for both collections by using 100 cubic meters of golf balls for every one of footballs, and then your logic would say the golfballs are bigger... even though in both cases, both are infinite. See the problem?.
How could the golfballs be bigger than the footballs, they were smaller when you started the infinite sets. Its not about the size of an individual golf or football, its about the size of the container 1 cubic metre versus 100 cubic metres. The spatial volume of the initiating sets.
I think you are messing with my brain for your entertainment
Philosophy is the set of things too vague to be science. This, on the other hand, is mathematics.
So far we have discussed this in philosophical terms and not in mathematical terms.
As far as Witt and Stenger --
Stenger says "Our universe may be no more than re-arranged, re-structured nothingness"
Witt says "Everything is constructed of nothing"
Whats different?
Witt also says the following --
1. Matter and antimatter are always created in equal, yet opposite amounts, whose electrical sum is zero.
2. Positive and negative electrical fields sum to a neutral universe with zero net electrical charge.
3. Energy is conserved in all interactions: the magnitude of of the universes energy has zero change.
4. Space is a collection of points, little bits of nothingness itself, embodiments of the geometric zero.
5. Charge must be conserved in particle interactions, the sum of charge differences is zero.
6. Momentum is conserved, so the universe's net momentum remains constant at zero.
What are your comments on these points as they sound quite reasonable to me.
