In special relativity, we know, (proper time)^{2} = - (proper distance)^{2}. But, in Causal Dynamical Triangulations (CDT), they introduce an asymmetry parameter \alpha as, (proper time)^{2} = - \alpha (proper distance)^{2}
[Q. 1] Can you please explain me about, why we need to introduce \alpha ? And, Is there is any useful resources to learn more about the role of \alpha in Quantum Gravity? Or, Any derivation relating to asymmetry parameter with proper time and proper distance?
[Q. 2] In most of the research in CDT, why they prefer to choose \alpha to be 1? Concrete reason needed!
[Q. 3] Does CDT prefer Time-reversal symmetry?
With thanks,
Damodar
