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'.
Yes, it is possible for there to be a region of space with no matter or energy under Loop Quantum Gravity (LQG). This is because LQG theorizes that space is made up of discrete, indivisible units called "quanta" which can exist independently of matter and energy.
In other theories of gravity, a vacuum is still considered to have a certain energy density and fluctuations in energy. However, in LQG, an area with nothing would truly have no energy at all due to the discrete nature of space.
Yes, even in areas with no matter or energy, there can still be gravitational effects in LQG. This is because the fabric of space itself can exert a gravitational pull, and the geometry of space can also affect the behavior of matter and energy.
Currently, there is no way to directly observe or measure the absence of matter or energy in a specific region of space. However, the mathematics and predictions of LQG have been tested and verified through various experiments and observations, giving credibility to the theory's concept of an area with nothing.
It is possible that an area with nothing in LQG could challenge our current understanding of physics. However, this is also the case with other theories and concepts in physics, and further research and experimentation will continue to refine and expand our knowledge. Ultimately, the goal of science is to push the boundaries of our understanding and constantly question and revise our theories.
