dead space
Empty wasted zone
Dead space is an area where something expected—air, signal, activity—doesn't reach or function.
In physiology, it's the part of the respiratory system where air sits without participating in gas exchange.
In architecture or design, it's unusable or wasted area: The closet under the stairs is just dead space.
In communications, dead space is where radio signals fail to penetrate.
The term suggests emptiness that serves no purpose.
