Re: Riddle me this:
No, you are not getting bigger because the molecules that make up your body are held together by forces that overcome any expansion in the space between them. Ditto for the entire Milky Way galaxy, and in fact our entire supercluster of galaxies.
Think of as post-its stuck to a balloon. If you further inflate the balloon the post-its get further away from each other but the individual post-its remain the same size.
At some rather large distance what gravity can do to pull two objects closer to each other in time x is overwhelmed by the expansion of space between the objects that occurs during time x. Thus they get further and further apart even as gravity still does its thing.
