Stephen Hawking is Building Interstellar Spaceships

Astrophysicist Stephen Hawking and Russian billionaire Yuri Milner are building miniature sized robots the size of a smartphone and sending them to Alpha Centauri - 4.37 light years away. “For the first time in human history we can do more than just gaze at the stars. We can actually reach them.”
Milner explained how breakthroughs in microfabrication, nanotechnology, and photonics have allowed us to build smaller, lighter, and more powerful spacecraft than ever before. Starshot will accelerate nanocraft to 20% the speed of light giving them the ability to make it to Alpha Centauri in only 20 years.
Stephen Hawking had this to say, “The limit that confronts us now is the great void between us and the stars, but now we can transcend it. With light beams and lightsails and the lightest spacecraft ever built we can launch a mission to Alpha Centauri within a generation. Today we commit to this next great leap into the Cosmos because we are human and our nature is to fly.”
Each nanocraft will carry a StarChip and be able to send photos and other information back to Earth. The vast space between Earth and Alpha Centauri is full of comets and asteroids. We could learn a great deal from these objects that have so far been too distant to study.
There was times when cable was important in our lives and allowed us to watch television in home with family or alone, however, today, media streaming devices are replacing cable TV and that is the reason we decided to show you why media streaming devices became so popular. In this particular article we are going to provide you with all relevant information that will provide you perfect idea what we are talking about. Read more
If we say that technology has completely changed the way people live their lives, then this will be a very true statement. Not only has technology contributed in getting knowledge about the human bodies, about our earth and a number of other things, it has also contributed to the field of construction. In the past, the way people used to go about the construction and the methods and machinery that was used in the construction field was totally different than what is being used now. Read more
