This is a cool article/pictures of a supposed comet collision at “hypervelocity,” a word which again reminds me, in conjunction with other recent posts, of Calvin’s excellent suggestion of renaming the Big Bang the “Horrendous Space Kablooie.” It doesn’t mention any proposals to change “hypervelocity” to “insane unthinkable instant death speed” but it makes it sound like the discovery was something of a “wtf” moment for astronomers.
