I am tired of the assertion that the Great Wall is the largest human construction, or the only one visible from space. Four thousand square miles of Holland (the quarter of the country that would be sea without human intervention) is surely bigger by volume, and naked-eye visible from further away. This makes KM3NeT third.

freaky, i am scared.

It reminds me of the Tower of Babel.

Geometeer, I think the point is that the Great Wall and the Pyramids were marvels created by the ancient world. Your marvel of keeping the sea at bay is a modern marvel, but it was done with modern machinery and engineering. The Hoover Dam was also such an engineering feat. The area of land that it made arable was considerable too.

All right Geometeer. Yours is bigger.
Anyway, back to the point, it seems that the scientific community is full on searching for WIMPs (to prove the theories of dark matter and super symmetry) by observing for example the annihilations of neutralinos. Very nice.
Is there a plan as to the whereabouts of the site ?

Riccobene\'s \"on the scale of human constructions, it will be second only to the Great Wall of China\" said nothing about date -- and date can hardly be the point, since KM3NeT will be \"done with modern machinery and engineering\". As to whether Holland was, the first stage was in the sixteenth and seventeenth centuries, which pumped dry many lakes for agriculture, with windmills. In the nineteenth century, they pumped more, by steam. Where does \"modern\" begin?

I thought the IceCube could see the galactic center just fine, since neutrinos are hardly affected by the whole earth mass.

I hate to ask an obvious question, but, how would this structure affect and/or be affected by, submarines? In peacetime, or during warfare? Will it be strong enough to pierce the hull of a nuclear submarine? \"It couldn\'t happen here [there, or anywhere]\" is not a comforting assurance. Neither is, \"We\'ll post it off limits on the charts\".

Labels like \"modern\" and \"natural\" are subjective and carry no objective meaning, making them useless for communicating ideas. I suggest that the first person to use their mind to survive was employing the most potent tool possible. Their technological development at that point is irrelevant.
Too bad this enterprise is not built for profit. It would be better and cheaper. The less public projects the better, no matter how grand they seem.

Where the detector is placed is dependent upon what type of Nutreno is to be observed, what advantage is there to having a detector in a busy shipping lane full of plankton, silt debris and sonic disturbance over the current methods of using glaciers in the Antarctic and solvent tanks in salt mines ?.
Looks cheaper with a large number of detector towers mainly by people who do not understand the expense of working in such an extreme environment for a long time. In 1901 Marconi\'s first antenna at Poldhu was destroyed by storms, a very similar structure to this one. One pressure wave from a distant landslide would do horrible things to the instrument. To get a quick repair job done it is a far cry from erecting 2 masts and a long copper cable.
