Quanitized Space & Black Hole Formation

In summary, the conversation discusses the idea of how matter in a forming black hole may affect the transmission of gravitons due to the quantization of space-time in Loop Quantum Gravity. It is proposed that as the matter collapses and becomes compressed, it may prevent the transmission of gravitons and other particles, potentially eliminating the singularity at the center of a black hole. Research has been done in this area, but the exact effects are still unknown.

demiurge

Hi, I'm an amateur cosmologist/physicist and I was hoping that someone more well-versed in these areas may be able to comment on this idea that I have.

Assuming space-time is quanitized and the universe is limited to 3 spatial dimensions (as in Loop Quantum Gravity), has any research been done on how the matter comprising a forming black hole may affect the transmission of gravitons within the collapsing star, i.e. as the matter collapses to the point where it is compressed so greatly that their are literally no empty interstices between the component matter, is it possible that what would seem to be an impenetrable layer of matter stacked together in shoulder-to-shoulder Plank discreteness could prevent the transmission of gravitons (and possibly other force-carrying particles) and thus prevent the black hole from collapsing into a singularity?

Thanks,
Chris Granger

Space quantization doesn't just mean some standard sized small modules like some checkerboard lattice. It means the quanta of space will be established by some projection operation - observation, or decoherence, or whatever. The size of the observed quanta will depend on the energy they contain. Just as in ordinary QM the higher energies will be associated with shorter distances, so the quanta in the center of the black hole would get smaller accordingly. Of course the hope is that LQG will eliminate the singularity at the center of a black hole and so they wouldn't have to go to the limit of zero volume.
 

1. What is quantized space?

Quantized space refers to the concept of dividing space into discrete units or chunks, rather than being continuous. This idea is a fundamental aspect of some theories in physics, particularly in quantum mechanics.

2. How does quantized space relate to black hole formation?

Quantized space plays a key role in the theory of black hole formation. According to some theories, during the formation of a black hole, space itself becomes quantized, meaning that it is divided into discrete units. This is believed to happen at the event horizon of the black hole.

3. What evidence supports the existence of quantized space?

Currently, there is no direct evidence for the existence of quantized space. However, some theories, such as loop quantum gravity, make predictions that could potentially be observed through experiments or observations. Additionally, the concept of quantized space is a fundamental aspect of many successful theories in physics, such as quantum mechanics and string theory.

4. Can quantized space help solve the problem of singularities in black holes?

One of the major challenges in understanding black holes is the presence of singularities, which are points of infinite density and curvature. Some theories, such as loop quantum gravity, propose that quantized space can help resolve this issue by providing a more complete description of space at the quantum level. However, this is still an area of active research and there is no consensus on the role of quantized space in solving the singularity problem.

5. How does the concept of quantized space impact our understanding of the universe?

The idea of quantized space has significant implications for our understanding of the universe, particularly at the smallest scales. It suggests that there is a fundamental discreteness to space, which could have profound consequences for our understanding of gravity, time, and the very fabric of the universe. However, much more research is needed to fully understand the implications of quantized space on our understanding of the universe.
