An Asian studies expert and amateur satellite tracker have voiced their concerns over the possibility that China’s Tiangong-1 space station may be de-orbiting without control from the ground. The station, launched in 2011, was a temporary testbed for the technologies for Tiangong-2, a permanent station scheduled to be launched in September of this year. Beijing’s original plan was to de-orbit the spacecraft in 2013, but Tiangong-1, Chinese for "Heavenly Palace 1", remained in orbit after that date, conducting long-term endurance tests of the now unmanned station’s components.

100 years after Albert Einstein predicted the existence of gravitational waves through his theory of general relativity, a team of astrophysicists has announced the detection of these distortions made in the fabric of space. "With this new discovery, we humans are embarking on a marvelous new quest: the quest to explore the warped side of the Universe—objects and phenomena that are made from warped spacetime," remarks gravitational physicist Kip Thorne.

Of the four fundamental forces known to science in our culture, there are only three that can be manipulated: electromagnetic, strong nuclear, and weak nuclear. Eluding our grasp thus far is the ever-important force of gravity, forcing us to expend large amounts of energy to leave the planet’s surface. However, a revolutionary proposal has been made that may change that situation.
