Suppose you have two light waves which are coincident and inverted.
They would cancel each other.
***yes***

If energy waves are random some waves are adding while others are subtracting.
***no total cancellation***

But suppose a majority of waves were created in a single event, like the “big bang” and energy waves were created in a way that they tended to be opposites.
***no opinion-they would probably separate and not interact***

If two incident waves which are canceling eventually separate, would they appear to be created out of nothing?
***yes, depending on perspective. Focussed laser beams can do that***

Would they still exhibit mass according to the equation M = E/C^2 while they air cloaked?
***no- photons have pressure but no mass***

If they did then space itself would exhibit a background invisible mass.
***it does anyway- called dark matter***

This mass may not be detectible in most conditions due to an density distribution which is close to a constant.
***not so- it would affect to motion of planets and stars, which are observable***

*** In addition space itself has dark energy which behaves like a mass in keeping the universe flat- if you kjnow what that means***
