Our "visible" universe is the sphere of space that is within 13.6 million light years. We do not know and cannot know how much larger space actually is outside that bubble.

This is interesting, and illustrates my quandry. How can two objects, which are "within" each others' perceivable Universe, become 13B light years distant in a span of 600M years? Perhaps the Earth and the exploding star have been receding from one another at a rate approaching light speed, causing the light from the star to be coming toward us at far less than light speed due to a Doppler Effect. And yet.....that defies the principle that light travels at......light speed.
I have a headache.
