"Quantum Foam, Space-Time is much less "Foamy" than models predict.
Quantum foam (also referred to as space-time foam) is a concept in quantum mechanics devised by John Wheeler in 1955. The foam is supposed to be conceptualized as the foundation of the fabric of the universe."
NASA's Kepler spacecraft is a prolific hunter of planets outside of our Solar System. Since it launched in 2009, Kepler has confirmed more than 1000 of these exoplanets and catalogued thousands of more candidates. The menagerie includes planets with densities greater than iron and lower than Styrofoam; planets smaller than Mercury and bigger than Jupiter; planets with one sun, two suns, and even four suns!

On March 19, 2010, NASA and Boeing successfully completed the initial flight testing phase of the X-48B. Fay Collier, manager of the ERA Project in NASA's Aeronautics Research Mission Directorate commented on the completion of the first phase of testing saying, "This project is a huge success. Bottom line: the team has proven the ability to fly tailless aircraft to the edge of the low-speed envelope safely."

Following the installation of a new flight computer in 2010, the X-48B was to continue a new phase of flights tests to investigate controlability aspects. The second phase of flight tests with the X-48B began in September 2010.
The X-48C first flew on August 7, 2012. Engine yaw control was among the aspects to be studied.] The X-48C completed its 8-month flight test program with its 30th flight on 9 April 2013.
The Boeing X-48 is an experimental unmanned aerial vehicle (UAV) for investigation into the characteristics of blended wing body (BWB) aircraft, a type of flying wing. Boeing designed the X-48 and two examples were built by Cranfield Aerospace in the UK. Boeing began flight testing the X-48B version for NASA in 2007. The X-48B was later modified into the X-48C version. It was flight tested from August 2012 to April 2013. Boeing and NASA plan to develop a larger BWB demonstrator.
