How is spacetime quantized?

[Guest]

FYI: "The construction of accelerated fields differs from ordinary quantum field theory and provides a mathematically consistent way to quantize spacetime. In this approach, space and time are quantized in the way quantities like energy and momentum are quantized in ordinary quantum field theories."
