| There is a constant search for means of attaining maximum acceleration; which is limited by the power source. In any event the procedure transpires in the following manor: When grampa pushes grandson on a sled to get it going fast, so that he can jump on the back and they can get a nice long slide, despite the short slope; the energy thus transferred to the sled per second dwindles slightly with increasing velocity, accompanied by a dwindling of the force, exerted, and the energy transferred to the sled by grampa. When grampa feels that the sled is no longer accelerating or responding to his maximum effort, he either lets go, or jumps and lands with his knees on the back of the sled, and whee they _go_. This limit, or equilibrium, occurs despite the strength of the force and energy transferred: That's why nothing but light can be accelerated to, or travel at, the speed of light. Don |

Another factor to think about would be that grampa himself must also be accelerating at the same rate as that of the sled in order for him to be in contact. But this means that no force will result...hmmm - would be no different to 'pushing' the wall. Does light 'accelerate'? Anyone? |

Maybe in a cyclotron the size of Texas(;^) You're quite the BS artiste' there double A; no wonder the teachers got discouraged with arguing with you and gave you A's. Like the employer gives his worst employee a good recomendation in hopes he'll be rid of him(;^) Are you saying that if grampa had a long enough arm and unlimited running speed, he could accelerate the sled and grandson forever? What's this business about his irresistible force pushing an immovable wall? Would the two cancel(;^? Don |

But then you get back to the question of how grampa manage to store all that energy. Think about this. If you were grampa and started to push your grandson like how you descrbed it you would probably get to a certain speed before you start to lose contact - your maximum speed which is equal to the sled's. Now you give the sled to, say, the fastest person in the world, he would manage a higher speed. We could ignore air resistance and friction for the time being to understand this concept. What I said about the arm was just a joke. So my point is, given that there is some kind of person or thing that could accelerate this sled without any speed limit, the sled will indeed keep going until the physical factors kicks in to prevent it from going further namely friction and fluid resistance. There is no acceleration limit (in Newtonian mechanics) unless you take speed of light (quantum mechanics) into account. |

However I think we'll eventually find that light speed is just another barrier that will be obtained. sound gave us a sonic boom. I imagine a bright light flash as a result of obtaining the speed of light, however I'm 99% positive that it won't effect time. ring |
