ok, so congrats to the scientists for finally solving the transportation problem (I assume, its the solution. Still needs to be discussed by the fellowship)<p>but, how the pyramids actually have been built? I mean the stacking of the tonnes of tonnes of rock. From an engineers sight, there are a lot of possible ways - but, how has it really happend? i think, that, we never will find an answer for it. Its a little bit sad - just out of curiosity!
