Hi there,
"LQG does not make any testible predictions, and even if it did, there is no built in mechanism to bring an ever expanding universe to contract in the first place. So for now, the bang will not be replaced."
on the contary it does, for one the photons traveling from distant Galaxies, ones with a higher energetic level, will travel slighty faster than its lower engergy counterparts, can't recall why this is so... I am guessing its a result of the (higher engertic) photon taken a the path of shortest distance - or ligh cone (LQG spacetime is not consitanty smooth, but rather bubbly)
