Intimately related to this is the veil of ignorance. This concept merely extends and completes the previous thought: Not only is everyone starting at some hypothetical ground zero, but no one, including the legislative mind, knows what his position in society will be after the laws are enacted...

...solely by gravity. He proposed that "ether," an invisible theoretical substance that at the time was believed to pervade space, exerted drag on the nucleus, slowing it down. After observing flares streaming from Comet Halley's surface in 1836, another German astronomer, Friedrich Wilhelm Bessel, conceived a more plausible concept, the fountain theory. Bessel proposed that a comet was a loose clump of particles. He suggested the flares were fountains of these motes erupting from its nucleus and that they acted as a brake. Bessel's work was largely ignored at the time, but it turned...
...most important contributions from the Vega program will be what is called the Pathfinder concept. Together the probes will attempt to reckon the position and orbit of Halley's nucleus with a precision impossible from ground-based observations and then beam the data back to the Soviet Union, which will in turn relay the information to European mission control in Darmstadt, West Germany, in time for Giotto's rendezvous on March 13. Precision is of the essence: zeroing in on a nucleus that scientists estimate measures only two to six miles in diameter and is traveling some 154,000 m.p.h...
