Undersea Neutrino Observatory To Be Second-Largest Human Structure

cylonlover writes "An audacious project to construct a vast infrastructure housing a neutrino observatory at the bottom of the Mediterranean Sea is being undertaken by a consortium of 40 institutes and universities from ten European countries. The consortium claims that KM3NeT, as it is known, will 'open a new window on the Universe,' as its 'several' cubic kilometer observatory detects high-energy neutrinos from violent sources in outer space such as gamma-ray bursts, colliding stars and supernovae. On the scale of human constructions, it will be second only to the Great Wall of China."

a bit disingenuous

I think it's a bit disingenuous to say that this is the second-largest human created structure. While this is an impressive experiment which I think is very clever and great for physics, calling this a structure is a bit of a joke. If you were to call an array of phototubes a structure you could easily compare it to, say, the street lights of Los Angeles -- which I'm sure would be counted as a larger "structure".

It's sparse

No, it's not the biggest. The Deep Space Network has satellites (antennae and data storage servers) around Earth and around Mars. And neither it nor the KM3NeT are solid structures.

The Great Wall is not strictly connected either but at least it consists of large solid fragments that are big on their own. This observatory is merely an array of sensors suspended in the sea. If you want the biggest structure, I'd look at a road system of a country.

Not to mention, say, "the North American power grid" or "the global fiber optic network".
