Everything affects everything else

Think I agree with the basis of astrology. Everything in the universe affects every other thing. The intensity depends on the size and proximity. A car passing by will cause a turbulence in the air, the intensity is highest closest to it. For a hapless fly, this may be enough to cause death but an elephant will barely feel it. By the way what is the perspective of say a worm in the stomach. It sees its sky as red because the sunlight percolates through the tissue of its host. It hears a constant rumble from an unseen heart. It gets rained with food and water at more or less predictable intervals. Now suppose we are in a similar situation, confined in an unknown limited space. Is there a larger world out there?
