Hello David,Yes, in the most recently accepted theory the SEB returns starting from one (subsequently up to 3) location and then expanding to created the dark/light markings of SEBn and SEBs. So what you see as dark spot is in reality one of the source of the dark matter (maybe soot?) that will become part of the newly formed SEB.Andrea T.
