Dang.
I started writing something about it probably being positive, given that many things in the physical world seem to drop back to a baseline after a disturbance, but then I remembered we can see the oldest galaxies by light that seems to travel forever, and it also occurred to me that a disturbance isn't the same thing as changing a vector, which can definitely be irreversible, and I realized I was heading for the deep end of the pool. Think I'll just stay here and paddle around.
