Consider: If New York were its own country, its army, the New York City Police Department, would be the twentieth-best-funded army in the world, just behind Greece and just ahead of North Korea. Its GDP, $413.9 billion, would be the seventeenth largest, just behind the Russian Federation and just ahead of Switzerland. With more than 8 million residents, it would be more populous than Ireland, Switzerland, or New Zealand; roughly half the countries in the Middle East (including Israel); most of the former republics of the Soviet Union; and all the Scandinavian countries besides Sweden.

We’d be a great trading hub, the city Hong Kong was before it was handed back to China; an international capital of media and entertainment where news, books, and watchable films were peddled and made; and a diplomatic outpost, mediating between that lone superpower the United States and the rest of the globe. But best of all, we’d be able to define ourselves. Gone would be the days as a neglected appendage to an indifferent nation; instead, we’d be “an antenna to the world,” as Shashi Tharoor, an undersecretary-general at the United Nations, once gorgeously described us. And New York City—home to 600,000 Muslims, cauldron of more than 160 foreign languages, birthplace of Jonas Salk, Kareem Abdul-Jabbar, the brothers Gershwin, the telegraph machine, the hot dog—would no longer be identified with a country the rest of the planet hates, fears, and cannot understand.

The Earth is gradually vanishing from the view of any aliens that might be looking for us, because we are using fewer technologies that leak radio waves into space.

This is the view of one of the pioneers of the SETI project (that stands for Search for Extra Terrestrial Intelligence, in case you just crash landed), Frank Drake.

His remarks cast doubt over the current search methods employed by SETI in their hunt for little green men, but, he says, also suggest a reason for the deafening silence out there.

According to New Scientist our transition from radio tranmissions to cable TV could mean that our window of detectability is no more than 100 years.
