Move Over Arecibo -- China Assembling World's Largest Radio Telescope

China is assembling the world's largest radio telescope deep in the mountains of southwest China's Guizhou Province. When it is completed in 2016, the new 500 meter radio telescope will be the world's largest, overtaking Puerto Rico's Arecibo Observatory, which is 300 meters in diameter.

If my estimates are correct, and they may be little off, it looks like about a 6 dB increase in signal at ~1.4 gHz. At first I thought this wasn't much, since that's only about 1 standard S Unit or doubling the signal twice. However, since we're talking about noise level, this could mean detecting signals from stars much farther away than currently. It should also gives us better resolution in looking at the clumping of galaxies in the observable universe and help in deciding if the standard model or some other explanation is more realistic.

A monumental waste of time and money...

Great article :-)

Particularly interesting if you have read Cixen Liu's "Three Body Problem." <br><br>
