So our telescopes only show us the universe in its past. Wouldn't it be nice if we could see the present? In fact we're building them right now - the gravitational interferometers. But you say even gravitational waves take time to propagate, so we really couldn't see the present even if we wanted to. Yes unfortunately this planet is being accelerated so we can't see anything in the present. However we sure could see a lot more considering all matter created during inflation is now in gravitational communication since the universe was very small at that time. The trick is when objects accelerate the changes in their gravitational fields propagate only at the speed of light. However note static gravitational fields are in instantaneous gravitational communication.
