Its like gravity. You make a divot in spacetime, and things being to roll downhill toward the divot. Mass collects, attracts other mass, and soon you have a significant planetoid. Leave it alone long enough, you have a star, or in the case of some places, a black hole. In HSV case, several significant divots. NASA MSFC, Army Materiel Command (Logistics), and the Missile Defense Agency. Caveat on living here, if WWIII happens, we will get nuked.
