Empty space Quote by Henning Genz
““It is impossible to bring a substance down to a temperature of absolute zero; there cannot be a blackbody without radiation because absolute zero cannot be reached. And that means that empty space in its true sense cannot be created.””

Source Lecture: Thermodynamics and Quantum Mechanics, 2019
Matter cannot be cooled to absolute zero, so any object, even empty space, must emit radiation.
In simple terms: Absolute zero is unattainable, so true emptiness doesn’t exist.
