ONeill Cylinders Essay -- physics space

Science fiction authors for many years have written book after book exploring, as Star Trek described space, the closing frontier. While many spate focus on the exploration side of space, there are some who believe that space is our next refuge. Stephen pitch has said I dont think the human race will survive the next thousand years unless we spread into space. While some spill of moonbases, or planet-side bases, star of the most intriguing ideas is the ONeill Cylinder.Gerard K. ONeill created the ONeill Cylinder in his book The High Frontier. An ONeill Cylinder consists of two cylinders which counter-rotate around each other, each one has a two mile (3 kilometer) radius, and a 20 mile (30 kilometer) length. The two cylinders counter-rotate to create simulated gravity by centripetal force everything is pushed to the outer mole due to that force. However, some design choices stem from this, some to combat the negative effects, and others to take advantage the centripetal force. Due to the nature of artificial gravity, many people might experience nausea and dizziness. To combat this, the speed of rotation would need to be decreased to about two revolutions per minute. To take advantage of artificial gravity, diametrical parts of the ONeill Cylinder can rotate at different speeds. In the middle of the cylinder, the artificial gravity will be smaller than everywhere else in the cylinder, and manufacturing facilities would be placed here to take advantage of that fact.The cylinders themselves would have six sections on them, half of them are windows, the other half is the ground. Behind each window would be a mirror so they could direct the sunlight into the cylinder, while night could be simulated by simply moving ... ... an object is at a Lagrange Point, it acts much the same as a satellite that is in geosynchronous orbit with a planet. Things at a Lagrange point are at a fixed place in space, which is quite an advantage for ONeill Cylinders.Bibliography BooksONeill, Gerard K.
