Physics In physics, the word nothing is not used in any technical sense. A region of space is called a vacuum if it does not contain any matter, though it can contain physical fields. In fact, it is practically impossible to construct a region of space that contains no matter or fields, since gravity cannot be blocked and all objects at a non-zero temperature radiate electromagnetically. However, even if such a region existed, it could still not be referred to as "nothing", since it has properties and a measurable existence as part of the quantum-mechanical vacuum. Where there is supposedly empty space there are constant quantum fluctuations with virtual particles continually popping into and out of existence. In the context of the multiverse, nothingness can be conceived of as that within which no space, time, energy, matter, or any other type of information could exist (such as tears or holes in the structure of the manifold of the multiverse itself). It had long been theorized that space is distinct from a void of nothingness in that space consists of some kind of aether, with luminiferous aether postulated as the transmission medium for propagating light waves (whose existence has been disproven in the now famous Michelson–Morley experiment).
