...though admitting that theoretical explanation fails because of lack of knowledge.
If I've not misread it, this is what Rossi says too and he can't get the theoretical bit sorted out. If he has succeeded or not I can not tell but I do applaud his efforts. Unlike you he has the means and the guts to have a serious go for it, instead of entertaining a impossible attitude.
However this is something of great importance to understand. I do not believe our laws of thermodynamics will survive in their current iteration if we are to reach the next level. Nano engineering for example if we are to get there will require vast amounts of energy and we need to master the atom if we are to build with atoms. If you are really into science, expansion of knowledge tends to not quell questions but raise more of them. Which in turn demand more knowledge in order to be answered. It's a hopeless cycle which is seemingly infinite however I tend to believe that we in this situation would be limited by our own capacity to understand the universe. It would be a shame to let it end at this point, don't you all agree?
