**Physics, Astronomy & Cosmology / Is there a difference between zero energy and a zero balance of energy?**

I’ve tried on a number of occasions to get an answer to this, including in a recent thread. Perhaps separating it from other material might do the trick.

Consider the statement: “The total amount of energy in the universe is zero.”

Are there two ways in which this could be interpreted?

1. There is no energy in the Universe.

2. There is a specific amount of positive energy in the Universe. There is also a specific amount of negative energy in the Universe. These amounts are equal, therefore, the balance is zero.

In the case of our Universe, there is, manifestly, an energy content, therefore 1 cannot apply.

If 2 is the appropriate interpretation, although the positive and negative energies cancel each other, they cannot destroy each other; thus, there must be a difference between “zero energy” and “a zero balance of energy”.

I’m prepared to acknowledge that my reasoning could be wrong, but I would appreciate knowing how/where.
