If I understand you correctly, Ive long thought about this as well! Note you should clarify that by "slowing of light" you mean a lowering value of the absolute speed of light. While Einstein assumed it was constant, yet said speed and time we're changing. It's actually simpler to say the opposite; speed and time change because speed of light (c) changes .
