number system goes from 0 to ∞ (and 0 to -∞ for negatives)

 

as far as i know nothing in our physical world holds no mass and all matter is energy (correct me if i am wrong)

 

now, my question is: can nothing be calculated?

There are massless particles - for example the rest mass of the photon is zero.

 

However, even if there weren't, I don't see how that nothing can be calculated follows...

Care to explain?

There are examples of situations where "zero" is a mathematical prediction of a model — a permanent electric dipole moment of an atom, for example. Measuring that it is zero is what is essentially impossible. All you can do is make the uncertainty as small as possible.

Of course, that's not unique to zero. No measurement is infinitely precise.

Zero is a mathematical object. and the concept should also be considered in physics. Nothing in our physical world holds no mass and all matter is energy.

 

and what is the one type of energy that creates action at a distance and en-compasses our atmosphere but is also the least understood while it is in motion?

 

I ask only because it goes in a circle. It is all cyclical.

I can calculate plenty of things. For example, I calculate that 1+1=2. But that can't be what you meant. Care to clarify?

Mathematical zero corresponds to physical nothing. For example there is no magnetic monopole, the "magnetic charge" of everything is zero.

No type of energy creates action at a distance. That would have to be a force.

I don't know what you mean.

But zero presents special problems. You can measure zero by mistake quite easily — leave something unplugged. Showing that you actually measured zero carries some extra baggage with it.

It is considered in physics, like any other number.

 

Nothing in our physical world holds no mass and all matter is energy.

Things that carry no mass include the photon, gauge bosons and gluons.

 

and what is the one type of energy that creates action at a distance and en-compasses our atmosphere but is also the least understood while it is in motion?

Nearly all type of energy create action 'at a distance'.

Do you actually mean anything by this at all?

sorry for unclear question. thank you for the responses...i am beginning to understand...

 

Look at it this way.

 

Object A (doesn’t exist) – can be calculated? No

Object B (existing but, for example, not in motion or zero) – can be calculated? I don’t know.

Calculation could be in terms of time and space.

I think the word "calculated" is causing some confusion. I think what you mean is more like "measured."

 

So, yes, something with no measurable effects cannot be measured (he said tautologically).

I can calculate things that don't exist. We do that in physics class all the time. In fact, in physics class we hardly ever calculate things that do exist (frictionless surfaces, I'm looking at you!).
