"What if aliens live on a different timescale than us, such that blinking their (presumably proverbial) eyes takes centuries? The speed of light suddenly feels a lot faster!" I think it's reasonable to assume that natural selection wouldn't favor that timescale. For one, cosmic catastrophies - and resulting extinction events - would be much more often from the perspective of a "slow motion" lifeform. On the other hand, from the perspective of "super fast living" creatures the universe would appear as a much more peaceful and friendly place.
