List of all zero energy things in our universe?

Nothing. Not even the vacuum of the deepest space. Not even a substance at absolute zero. They all have a minimum of energy. Look up zero point energy.

Anything with mass has energy; anything that can apply a force over a distance has energy.

 

I think Atheist got one though.

Energy is a property of "stuff". So, as Atheist points out the question is not very well posed.

 

Another point is that having zero energy is not quite the same as having no energy.

 

My example, the vacuum of a supersymmetric theory has zero energy. If the supersymmetry is broken, then it has a positive non-zero energy.

What about blueberry Pi?

 

No actually (;)) I'm referring to non-concepts. Maybe someone is able to help me phrase the question better, then I can post it as a new thread. I asked the question in that manner only because the results of an earlier attempt suggested it's better phrased this way.

I think the answer is, "the list of all things that do not physically exist."
