Which is more likely, that you can have infinite free energy or that the very careful measurements of the distances to supernova that happened billions of years ago on the other side of the universe, and for which we have virtually no standard yardstick to compare against are not accurate?
You are just making an appeal to ignorance. All of physics and astronomy is based on the assumption that the rest of the universe follows the same basic laws that the part we can study follows.
That the universe is isotropic and homogeneous is a necessary basic assumption to even begin to measure the distance to objects that are very far away. If you can't assume that the basic laws of physics operate the same everywhere, then you have no basis to make any claims about anything that isn't local.
