The energy density of E&M waves in intergalactic space
I think the author is trying to ask about the energy present in the space if it’s just an empty void I mean there’s nothing around it yes for surely if it is surrounded by some luminous object the energy … We have geometry associated with it how to space is being curved the energy would depend on that also how much the area is also the time span for calculating the energy of that particular area, dark energy …
