As any of us go about our daily business, it is certain that we give our universe little or no thought. It just doesn't seem to affect our lives. It seems too much to comprehend.
Because our lifespan is short compared to anything geologic or astronomical, forget universal, it probably does matter little that our universe is expanding. Of the hundreds of billions of galaxies we are aware (as scientists ) the ones further away from some hypothetical universal center, are flying off away from everything faster that the ones closer in.
So, if we had a few hundred thousand years at the speed of light, we might make across our own galaxy and do a little scientific exploration. But, we had better get a move on if we want to explore any more of the universe in person, because it is all running away from us at tremendous speed.
