If light is not a constant in space then why do we measure distances in light years? If magnetic fields alter the speed of light then how is light speed an accurate form of measurement in space?
Could it be that stars and galexies are closer or farther away than calculations based on the speed of light due to the altering of lightspeed if magnetic fields do in fact alter. Thoughts?

Excellent question! Light slows down when it passes through, say, a prism, where it is refracted but, on exiting the prism, it regains it's speed (Constant) WITHOUT any energy stimulus. Your question goes right to the heart of Einstein's big mistake. Einstein said that space could be bent because he had seen radio waves being deflected. He forgot that space, as a vacuum, which is NOTHING, could not be bent. What he missed is that the radio waves were deflected by the gravitational fields of black holes. Now, if you want to progress, read my web site, it is just a theory but the most comprehensive so far as it answers every question. It will take 20 minutes to read and is written in plain English so is easy to understand. Your comments or questions are welcome using the feedback page, OK?
