A robotic truss builder that was conceived, designed and built by Caltech researchers has successfully built a structure in space—without the help of astronauts—for the first time. The truss builder, part of DARPA's Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design (NOM4D) program, consists of an autonomous manipulator that picks up struts and joints held in nearby dispensers to repeatedly assemble identical sections, or bays, of a perimeter truss.

Vibrating mirrors of light create analog of a black hole event horizon
Optical cavities are pairs of light-trapping mirrors and underpin the operation of lasers, atomic clocks and many types of precision sensors. If the distance between the mirrors is changed rapidly enough, some theories predict that the waves inside them should bunch together into
