50 years of space flight (1957–2007) have made the questions of gravity and weightlessness and their effect on man as well as the relationship of gravity to centrifugal force more prevailing than ever. Manned experiments with weightlessness have become possible and are performed daily and bring up questions on the still unknown entity of gravity. Due to space flight medicine’s view has become more precise in front of the astronomical front door in the whole solar system.

Until 1992 the solar system ended with Pluto as the ninth planet (discovered 1930). Pluto was also considered to be the only Trans-neptunal Object (TNO). In addition there was the so-called Kuiper Belt (Kuiper Belt Objects) as a region which stretched for a distance of 30–50 astronomical units (AU) outside of the Neptune orbit. Based on studies of comet orbits a hypothetical circumsolar comet cloud was assumed which today is called the Oort cloud. It spherically encloses the solar system at a distance of three hundred to one hundred thousand AU. Today the KBOs, TNOs and the Oort cloud objects (OCO) have become the richest astronomical era of discoveries.

Vienna in the last few years has successfully published the exact size of the fields of gravity of the planets and compared them to the orbits of the newly discovered moons. Normal matter, as we have known for it centuries, has become rare in space. According to the latest views of astronomy the largest part (95%) of space consists of dark matter and dark energy which also show signs of gravity.
