JD: Are we misusing the term shower? Is it the Earth going through all these items in space or are they actually falling towards the Earth?
DD: Well these debris clouds are orbiting the sun as well and what happens is our orbit of our Earth happens to intersect their orbit that’s when we see them. So everything is moving. We actually move through there and we would say we sweep them up. So our gravity captures them so then they fall through the upper air.
