The term Euclidean quantum gravity may make you want to nod off.
Metric tensors are used to define the angle between and length of tangent vectors (somewhat analogous to the dot product of vectors in Euclidean space)
Just as it is unscientific to look for square circles in Euclidean geometry, so it is unscientific at this stage to look for purely chemical and physical explanations for life.
Not in Euclidean geometry, another abstract system.
For example, photons (which appear as particles in Euclidean space traveling at the speed of light) take advantage of the ultimate "shortcut" available in Minkowskian geometry.
Approximately equal to 3.14159, Pi represents the ratio of any circle’s circumference to its diameter in Euclidean geometry.
They were trying to use the particular technique called Euclidean Quantum Gravity (in which you temporarily forget that time is any different than space) to calculate rates at which different things could happen, when the stumbled across a puzzle.
To justify “2” rather than any other close number, we need only one assumption - that the space is Euclidean, which is eminently reasonable.
(The theory of relativity showed what had been held to be an example of the synthetic a priori, namely Euclidean geometry, to be false as the geometry of physical space).
This restriction of the model is called the Euclidean “kernel” of the model.
