(Jon sez:) ![]() You can see these structures for real in Tycho Crater on the Moon. A pair of binoculars is enough to display Tycho in all its glory. Science note: An impact at 300 kph would create rays and an ejecta blanket only in very soft materials. In fact, if you want to play Giant Death Crater at home, get a pan full of flour and drop a marble into it. You'll see cratering, ejecta blankets, and possibly ray formations - although if you drop the marble hard enough to form rays you'll probably have to spend some time cleaning up the kitchen... |
(Mark sez:) ![]() Speaking of awkward segues, I've been meaning to mention for a little while now that longtime fave comic Paradigm Shift has started up again after a hiatus. So you should definitely be reading it if you have a Modern Tales subscription or are willing to just dive in and hope to make sense of the story -- it's worth your while. |
