Spacetime isn't quantized as far as we know. We don't know since we don't have quantum gravity or ability to probe Planck scale. Quantum fields are continuous, it is excitations in the field, particles, that are quantized.
- amwet 3mo agoAh, I thought we didn’t have strong evidence either way. Regardless, I shouldn’t have stated spacetime quanta so matter-of-factly. I just have an easier time conceptualizing if I treat everything like hypervoxels and that leaked in.
- lmpdev 3mo agoThe answer is we don’t know for certain There are even some philosophers/mathematicians who attest to finitism (they’re not mainstream, though), but if correct would undermine our idea of fields and continuous structures more broadly
