No
local point of view. If you could be a global observer, the contents would indeed appear to be shrinking.
I'm just curious what implications this would have for cosmology. Would it change anything? What about gravity?
I was thinking about this in terms of size as well. When you look at a car in the distance, it looks like a toy car as it's about as big as a toy car would be in a closer frame of reference. So the sizes of things at least appear to be expanding and contracting relative to the observer, just like time. Could gravity
shift according to the observer as well, and we only experience the gravitational pull of the 'large' bodies we are in close frame of reference to, such as the sun and earth? What would this do to dark matter/energy theorizations?
