News - Alpha Centauri is one of the closest star system to Earth. The distance is "only" 40 trillion kilometers, equivalent to 4.37 light years. That's where the most ambitious mission in history to search for alien beings.
Inisiatornya there were three, the founder of Facebook, Mark Zuckerberg, a leading physicist Stephen Hawking, and the Russian billionaire Yuri Milner.
Summarized from the Daily Mail, Thursday (04/14/2016), the mission of finding alien life (alien) was named "Breakthrough Starshot" and cost an estimated 100 million US dollars.
"The Earth is a beautiful place, but probably will not be around forever. Sooner or later, we must explore the stars. Breakthrough Starshot is the first step that trip, "said Hawking.
Breakthrough project Starshot rely on thousands of small spacecraft named nanocraft launched into space by conventional rocket.
Once in orbit, nanocraft will start perjalannanya. Nanocraft very small, roughly comparable with the stamps. Weighing just a few grams. Propulsion concept something like the ship, which moves to the "withdrawn" by a kind of a special screen.
The difference, not the wind that will drive the display nanocraft, but a laser beam from Earth. Method "sailboat" is believed to make the tiny vehicle was moving at 20 percent the speed of light.The time required to reach Alpha Centauri was spelled out very short, only 20 years old. That period is much shorter than a trip to the spacecraft's fastest time, which takes 30,000 years to go there.
"The wall that limits us is much space between us and the stars. However, we will be able to surpass it with light, display, and spacecrafts lightest ever made, "said Hawking. Arriving at Alpha Centauri, nanocraft will search for planets similar to Earth and take a picture.
Will take yearly to send the photo as an electromagnetic signal that is used as a medium sender moving at the speed of light, while light takes 4.37 years to reach Earth. The problem is, before any can dispatch nanocraft, scientists on Earth takes many years to develop related technologies.
Coupled with the time travel, it seems citizens of the Earth still had to wait a few more decades before they can see the photos from a neighboring star system.
