matter
I'm not sure what you mean by "resists change" but one word for something that takes up space and has mass is a substance.
Yes, a vacuum is still a vacuum if electromagnetic waves are present. A vacuum is an area with no matter in it. We know that matter is anything which has mass and takes up space. Electromagnetic waves have no mass, and certianly take up no space. They're energy.
A mathematical point in space has no dimensions therefore takes up no space. Certain particles have no rest mass but have the energy equivalent because of the velocity they possess. A singularity is a theoretical no volume point but has a huge mass.
Neither have mass or take up space
matter
No. Matter is anything that has mass and takes up space (has volume). Energy has no mass and does not take up space, therefore it is not matter.

Mass
Anything with mass takes up space.
matter
It is Energy; either this and/or empty space.
One object that takes up space and has mass is matter.Anything that takes up space and has mass is called matter in physics. This is anything that has physical substance.
Mass is defined as anything that has weight and takes up space.
Anything that has mass and takes up space is matter. Energy is not matter because it does not have mass nor does it take up space. Pretty much everything else is matter.
All matter 1) has mass and 2) occupies space (has volume).
Anything that has mass and takes up space is matter. Energy is not matter because it does not have mass nor does it take up space. Pretty much everything else is matter.
