Only way to account for red shift would be if the light is smeared as it's emitted.

Or lengthen on it's own the further it travels meaning light speed isn't constant and equations have to be recalculated to find the true age of things as they appear... Easier one would be if the light is emitted and drops to light speed as it is and the object emitting the light is moving relative to some other non expanding field the light latches onto. But then there should also be such high energy on the far side of the galaxies moving away at light speed+ that it should be measurable if it's there and if our technology can even see it with how it would technically be a wave that overtakes itself cause of the objects movement. So it should blue shift and then red shift at some speed as galaxies accelerate more somehow... They still haven't even bothered to address that matter at Lightspeed without expanding space issue yet either....
