I was watching this show and it was talking about the usual stuff such as wormholes and warping spacetime but the one thing that caught my attention was towards the end. I cant remember the guy`s name but he was talking about observing spectral lines and how when he had looked in one direction of the universe, EM force got weaker with distance. When he looked in another direction, EM force got stronger with distance. What would be the implications of this on current theories/understanding? Would there be a simpler explanation to what hes observed?
