Is Empty Space Truly Void of Energy and Matter?

[vivekfw66]

Is there in reality empty space where there is no energy or matter? or has anyone seen or detected it?

The concept of empty space would require a space devoid of matter, energy, or, more importantly fields. Gravity permeates the entire universe, so, the concept of space without the presence of a gravitational field is invalid.

This is not really a question that science can answer.

Detecting the absence of things is lots harder than detecting the presence of things.

It's a commonly asked question though. I see it here about once a month. Usually folks ask about regions with no matter, I think because they already get that, as Chronos pointed out, there isn't anywhere without fields.

EM radiation permeates space just as well as gravity does. So there is definitely no such thing as space without energy.

The OP has been answered. Now we are just inviting speculation.
