@exnihiloest Here's a question, if the physical reality put's constraints against our imagination then why does our imagination remove them?. You see at one time it was physically impossible that a machine which was heavier than air could fly through the air ...
This is a common misinterpretation of what Lord Kelvin (and also J. W. Rayleigh) said, a falsification of the History. People were not so idiot or naive, even at the time of Kelvin: every one knew that birds fly and that birds are heavier than air. What Kelvin said, after having calculated the weight of flying machines, is that there was no way to make fly a machine heavier than air, with the heavy motors of his time. But we perfectly know that the improvement of the technology can allow machines that were not possible in the past. The impossibilities of the past can be realities of the present. It is a triviality. Now it is one thing to "imagine" that objects will be perhaps possible and another to build them at the time they are imagined. Nobody prevent you to do science fiction or futurology. But we are not here for that. We are here to produce real machines buildable with the means of our time. For this goal, imagination is not enough if one refuses to deal with the present reality, the constraints of Nature and our technological means. It is obvious that "machines heavier than air" were impossible at Kelvin's time. At the Kelvin's time, you would have said "it's possible". I'm sorry to say that at the Kelvin's time, your assertion would have been as useless as almost all the today free energy announcements not supported by facts.
