[Grin] I have a conundrum for you What happens when an irresistible force meets an immovable object? Please explain this in extensive layman’s terms for us non academic types here Regards In layman's terms... something has to give. Imagine 2 freight trains loaded with gasoline tankers hitting head on at 100 MPH...BOOM No need. Neither object is unmovable (they would both be moving) and neither force is irresistable (else why the Boom Boom?) |

Neither object is unmovable (they would both be moving) and neither force is irresistable (else why the Boom Boom?) I understand that the premise of the original question is false. The simple answer... something has to give, means one either one object moves or the other resists. But even in that case, if they collide, there will be some type of reaction. If it's 2 freight trains or 2 ping pong balls, or even a train hitting a ping pong ball, the impact creates some type of reaction.     |

No need to imagine anything; the Law of Conservation of Energy states that Impact = Momentum (Pt=mv) Newton's three laws of motion; http://csep10.phys.utk.edu/astr161/lect/history/newton3laws.html point the way. |

Imagine 2 freight trains loaded with gasoline tankers hitting head on at 100 MPH...BOOM The answer is really very simple. An irresistable force cannot meet an immovable object. In any dynamic system, newtonian or einsteinian, where one exists, the other can not! |

You should have seen my first marriage - 3rd generation German-Italian-American meets well-established hillbilly on both sides. The answer is quite obvious - you duck and run!  |

Ok a 1cm diameter steel ball is traveling at 1 mile an hour slower than the speed of light. It approaches head-on the biggest black hole you can imagine. Since objects accelerate by the pull of gravity, will it violate the law of relativity? I trust this has been thought out, but I would like the full explanation as to why it would stop accelerating. 1 mile an hour slower than the speed of light is still the velocity of light, since this is absolute, so the question can not arise. |

Imagine 2 freight trains loaded with gasoline tankers hitting head on at 100 MPH...BOOM I'm trying to. Usually it's the LOCOMOTIVES that would collide head on. 100 MPH each or combined speed of impact? One of them is usually sitting around waiting for the other one to stop sitting around itself and pass it. Having the other go that speed is rarer than the nearly-the-speed-of-light ball hitting a black hole, er a planet. Gasoline is usually shipped by pipeline, another anachronism. Ask again in a few years if we are sending more ethanol by rail, since it won't travel well in a pipeline.
