My apologies on the worthless link then. It wasn't "obviously 'crank' or 'crackpot' as I read it, but I'll chalk that up to a lack of thorough understanding of the topic.
But to get on to the question, what is it that would limit the speed of the objects?
EDIT:
To be more precise, why would...
Three preconceptions for our thought experiment:
1. Gravity's effects propagate at a rate faster than the speed of light. This is demonstrated by the fact that the Earth is not thrown out into space due to the constantly shifting position of the Sun and an 8.3 min delay of "gravity waves"...
