Is there a vacuum?

What is this world made up of? Is it ultimately the energy that is distributed in various forms - one being mass - across the space? So what does it mean when one says that there are some places where there is nothing. That there is no energy at those points, at a particular instant of time.So there are pockets of voids for the energy distribution in the space. Can that really happen?

What is it that exactly defines a particular point in space? Is it only the type and quantity of energy at that point? Of course, the laws of nature must somewhere associated with each point - otherwise how will that energy pocket, sitting at that point, know what do next?

And what about the spatial co-ordinates?

(still to conclude...)

I think a point in space is defined by the so called spacial coordinates which doesn't have anything to do with mass. Space is defined is a place where there exists no mass. Though energy is convertible to mass (and vice versa). The place remains vacume untill the aforementioned act is performed neverthless the fact there exist zillions of energy packets floating around.

@ indianninerva:

Thank you for sharing your thoughts. Sapce is not a place with no mass. First of all, we need not consider mass specifically, since it is only one form of energy.

So coming back to my original question, I was asking if at all there is a vacuum at some point in space, that should mean that there is no energy at that point. Because when you have some energy located there (at that instant) it implies that there is some enery particle/wave there, which in turn implies that it is not vaccum!

But is that really possible or not is my question. Is is possible to have a spacial point with zero energy? I have not still concluded as you see, but just initiated the thought.
