> five times slower than what, where Slower than the time we measure here on Earth, or outside Earth/solar system/galaxy. They are very minor time dilation differences between those cases. > In particularly, how can you say time ran slower before such and such a time, compared to after, because those periods do not overlap; no meaningful comparison can be made. Of course you can compare different time periods. When the twin from twin paradox returns younger to Earth, you can say time ran slower for him in the past. We are actually seeing the past (of those quasars) unfold in slower time right now.
