The discussion centers on the theoretical concept of a train within a train and its implications for reaching or surpassing the speed of light. It is established that the velocity of a train within a train cannot exceed the speed of light, as demonstrated by the relativistic velocity addition formula: w = (u + v) / (1 + (uv/c²)). Key engineering challenges include overcoming air resistance, managing extreme centripetal forces, constructing a 40,000 km vacuum tunnel, and the immense energy requirements. Additionally, the accelerations involved would render survival for passengers in the inner train impossible.
PREREQUISITESPhysicists, engineers, and science enthusiasts interested in theoretical physics, high-speed transportation, and the implications of relativity on engineering challenges.
Air resistance, the absurd centripetal force required to keep the train near the surface of the Earth as trains need the speed of light go around the Earth 7 times per second.what would the main engineering problems which would have to be overcome?
No person could ever survive this due to the involved accelerations.and also what affects would this have on the person in central train after let's say a 1 day trip?
