China's Giant 'Alien-Hunting' Telescope Comes With a Human Cost
As headlines like " China uproots 9,000 people for huge telescope in search for aliens " suggest, people are justifiably upset about. It's especially egregious, considering that these folks are being paid a laughable pittance to move: 12,000 yuan. That's barely $1,800, and less than half the average annual salary in China .
Upsetting to be sure-but would people react differently if it were a highway or a dam? This telescope is a different breed of public works progress, on a different scale. It won't necessarily fix China's notorious traffic problems or keep the lights on in Shanghai. This telescope could help all of mankind to see the universe in a whole new way.
The 1,640-foot-wide telescope is called FAST (Five-hundred-meter Aperture Spherical Radio Telescope), and it's almost double the size as the next biggest radio telescope, a similarly shaped contraption in Puerto Rico. Its 460,000 reflective mirrors will reflect radio signals emitted by the universe onto a 30-ton antenna, which could help us unlock all kinds of galactic secrets, including whether or not we're truly alone in the universe. The $184 million project is supposed to wrap up in September after five years of construction.
But to make that happen, over 9,000 people will trade their homes for a small amount of money. China is actually nefarious for development-induced displacement. Back in 2010, a staggering 300,000 residents were moved back in 2010 to clear the way for the Three Gorges Dam. That seems like a paltry number of people compared the million-plus Chinese that were moved against their will for construction for the 2008 Beijing Olympics. In fact, since the '70s, over 40 million Chinese have been displaced due to various public works projects or infrastructure initiatives.
But this just isn't any public works project. It's one of the most ambitious
So FAST can help us study space at new, mind-blowing distances, and that has many benefits beyond the off chance that we discover life on other planets. As researchers from the Chinese Academy of Sciences reported when the telescope was still in the planning stages:
As the most sensitive single dish radio telescope, FAST would be able to discover more mega-masers and measure the radial velocities of masers with higher precision. This may yield more delicate dynamics of their maser spots. FAST will increase the precision of time of arrival (ToA) measurements for pulsars. This will help in detecting the stochastic gravitational wave background and in establishing an independent timing standard based on the long-term stability of the rotations of a group of millisecond pulsars. FAST might also work as a very powerful ground station for
the futurespace missions
And don't forget that NASA recently discovered
the most Earth-like planet ever found
Does the Chinese government need to treat the people displaced by this massive project better? Absolutely. But let's also bear in mind the fact that China's efforts in developing its space technology won't just help China learn more about the universe. It'll help everyone.
