According to QFT or Quantum Gravitation Theory space and time are discrete or continuous?
This has been discussed here ad nauseum. I suggest a forum search.Philipsmett said:According to QFT or Quantum Gravitation Theory space and time are discrete or continuous?

This is a fundamental question in the field of physics and cosmology. While some scientists believe that space is made up of individual units, others argue that it is continuous and has no distinct boundaries.
One of the main pieces of evidence for discrete space is the quantization of energy levels in atoms, which suggests that space is not continuous but rather made up of individual units. Additionally, some theories, such as loop quantum gravity, propose that space is made up of discrete units called "quantum foam."
The concept of discrete space is closely tied to the concept of discrete time. Just as space may be made up of individual units, time may also be made up of discrete moments. This idea is explored in theories such as loop quantum gravity and causal dynamical triangulation.
If space is indeed discrete, it would have significant implications for our understanding of the universe. It could impact our understanding of gravity, the behavior of particles, and the structure of the universe itself. It could also potentially reconcile the theories of general relativity and quantum mechanics.
Currently, there is no definitive way to test the idea of discrete space. However, some scientists are working on experiments that could potentially provide evidence for discrete space, such as measuring the smallest possible unit of space or observing the effects of quantum foam. Other scientists are using computer simulations and mathematical models to explore the implications of discrete space on the behavior of particles and the structure of the universe.
