... The Lin-Shu Theory | ... As we have seen here, understanding the spiral structure of galaxies took many twists and turns even in the hands of Bertil Lindblad who seems rightly regarded the main father of this whole subject. By the early 1960s, with the arrival of computers, plasma physics and several fresh investigators, it entered a new period of unusually vigorous activity, not always very united or monothematic, but broadly grouped under the umbrella marked `density-wave theory'. ...

... Then in 1959 the National Aeronautics and Space Administration asked the United States military services to list their members who met specific qualifications. The search was underway for pilots for the exciting new manned space flight program. In seeking its first space pilots, NASA emphasized jet aircraft flight experience and engineering training, and it tailored physical stature requirements to the small cabin space available in the Mercury capsule then being designed. ...

According to Velikovsky, about 4000 years ago a giant volcano on Jupiter erupted and spewed a vast glob of debris into space, leaving the Great Red Spot behind as a permanent scar. The red hot lump ejected from Jupiter (referred to as a comet by Velikovsky) wandered into the inner Solar System, repeatedly crossing the Earth?s orbit and in fact often passing close to our helpless planet in the following millennia. ...
