David Howell

David Howell asked Neil deGrasse Tyson:

Can you explain, if the universe is expanding from the point where the Big Bang occurred, how can the light from the objects (now) X billion light years away just now be reaching us? How did our slow selves physically get "out here" AHEAD of that light, while we wait patiently for it to arrive? In other words, how is the expansion of space faster than light?

Neil deGrasse Tyson Because there is no rule that prevents space itself from expanding faster than light, which the early universe surely did. Einstein's special theory of relativity restricts speeds to below the speed of light only for objects moving within space itself. So all is well in the universe.

Brian

Brian asked Neil deGrasse Tyson:

Hypothetical question, let's say we lived on a planet with a asteroid ring around it between the planet and the moon. I would assume the ring would be visible to the naked eye? What would it look like from the ground? Would we be able to track of the larger objects?
