The discussion centers on the concept of "nothingness" within the framework of Loop Quantum Gravity (LQG), specifically questioning whether an area devoid of quanta of space can exist. Participants conclude that true nothingness is a contradiction, affirming that such an area cannot exist. They emphasize that while an area may lack quanta, it cannot be classified as "nothing." The conversation also touches on the unclear physical meaning of the area operator in LQG, highlighting the mathematical nature of physics theories.

Something that is nothing ( a contradiction) does not exist. So the answer is 'no'.Lunct said:So if space is made up of spin networks and spacetime is made of spin foams, then say hypothetically, is it possible to have an area without the quanta of space? Say maybe if there is an end to the universe. Like a mega vacuum with just nothing in it.
well if you think about it is not really nothing. It is just an area that doesn't contain quanta of space. It is just as close to nothing as you can get. The human brain cannot comprehend nothing. Probably phrased my question incorrectly.Mentz114 said:Something that is nothing ( a contradiction) does not exist. So the answer is 'no'.
