“To my way of thinking, there is every bit as much evidence for the existence of UFOs as there is for the existence of God. Probably far more. At least in the case of UFOs there have been countless taped and filmed and, by the way, unexplained sightings from all over the world, along with documented radar evidence seen by experienced military and civilian radar operators.”
said George Carlin .
On this World UFO Day , let us take a look through the "Physics of UFO".
UFO
reports have been evaluated in terms of the supposed reliability of eyewitness accounts and questionable photographic evidence. The constraints that interstellar distances, time and the conservation of energy impose on interstellar space travel for these supposed alien craft seem never to be considered by UFO proponents. Since they do provide descriptions of spacecraft of circular disks, cylinders and triangles that move strangely and rapidly and vary in size from 50 feet in diameter to 300 feet long, I undertake here to apply these constraints to the design of a hypothetical spacecraft in order to determine the feasibility of such craft and their use for interstellar travel. As a physicist and astronomer I think it important to consider not just the accounts of alien contact, but the physics of such a possibility as well.
The basic principles of physics are applicable independently of where in the galaxy a stellar system is located and will not change over time. Newton’s three laws of motion and the conservation of energy are descriptions of the manner in which different parts of a physical system interact. Consequently, a model based on an exploratory expedition leaving Earth would apply equally to all planetary systems in our galaxy. Any culture, no matter how advanced in technology, would face the same constraints imposed by physics.
