If true – ESA experimental measurements of the polarization of

spacetime does not have a granular structure, which would have had a
measurable effect on the polarization of these distant gamma rays,
down to a level of 10^-48 m (which is exceedingly small)) trillions
of times smaller than the Planck scale.
Spacetime does not appear to be granular – at least down to these
incredibly small scales. These results have lead me to question any
hypothesis that seems to depend on spacetime having a discreet
granular structure.
Do you know if those are the results considered as "refuting" "loop
gravity"?
In fact, I find intuitive that a quantized gravitation lead to a
quantization of space-time curvature, and itself, but comp seems to
fit better with continuous space time, as it multitplies the comp-
histories in a very smooth way.
In the universal dovetailing, the winner "universal subdovetailers on
the programs defined on some "rich ring" structure, might be the
winner, but of course that remains to be shown.
Those questions are very hard.

Here is a link, which makes things seem very, curious, if true.
