Write4U Wouldn't it depend on whether you were observing from the 2d surface toward the 3d "construct" or from the construct looking "downward"? It can be very Alice in Wonderland, you know. It appears very solid up here(usually). I just have to say that while I accept their work, I'm not so sure of some of the "extrapolations" they make, we'll see, the LHC has probably already made the observations that will tell us which way to go, it's just buried in a gigaton of data. If tomorrow the LHC gets sucked into a tiny Black Hole just before it disintegrates into a burst of Hawking Radiation(a low, but not zero probability)the data is stored in a server several miles away. Er, come to think of it, they might want to move it a little farther out, the moon might survive it. GrumpyPlease Register or Log in to view the hidden image!
