If the maximum speed was say a 10th what it is, would it have any drastic changes in the universe?
I guess there would be more and bigger black holes and light would take longer to reach us, but what would be the main differences in the universe? Would it be much different?

does this mean that it has not traveled through time at all, but only space?
