Kind of a random thought from someone who has no business dabbling in quantum theory but i was wondering if this has could have any validity...
Theorists have derived that the universe is expanding more rapidly over time by studying the changing differences in distance between bodies in space. (bodies that are millions of light years from here) They then compare these changing distances to the changing distances of closer bodies in space. (im sure your all aware of how this works but bear with me...)
They are basically looking farther back in time the farther away they look.
My question is...
Could light over vast distances (3,000,000,000 light years or so) cause an acceleration or deceleration of time within that light stream? Could EMR from major events like a supernova be distorted or distorting the space time continuum and causing ripples in our data?
Im not trying to dispute the expansion of the universe, I'm just wondering if mass amounts of radiation over long distances could be manipulated by themselves and possibly other forces like gravity.
