Firstly, apologies if this is the wrong thread for my post. Please direct me if wrong. My first observation was this! If the universe is expanding at all points away from each other. Should that not mean that everything including us, our instruments our measuring tools and, in fact, the earth too? If so. We would not perceive an expansion because us and our methods of measurement would be expanding proportionately. Therefore, my assumption is... the fact we are observing the expansion means our planet, and us are not expanding. I am not getting bigger, and the distance between the gradient on my ruler are not getting Wider. Doesn't this mean that objects with mass are not subject to the expansion. But the space between? If this 'BIG' assumption is correct. What does this hold for gravity, space and time? space and time will become 'stretched' therefore wont Gravities effect on the universe become diminished as objects become further away from each other? For example, our orbit of the sun being affected as its momentum 'being proportional to space and time' overcomes the progrssively weaker gravity? My question is. Does this have an affect on the theory of special relativity?
