What we now see being influenced near our horizon reaches us by light 
that takes the same time to get here as the gravitational influence 
allegedly acting on those objects, so we should be experiencing the 
same influence, no? Well, suitably attenuated by inverse square 
diminution. I agree that this quickly gets out of hand for intuition 
unaided by elaborate mathematical analysis.
