It is certain that there won’t be any life on earth once the sun gets burnt out and it starts expanding to form a red giant which will end the earth and solar system. This is estimated to happen in five billion years from now on. But that time is very far from us, so we don’t need to panic right now. Besides, the search for another shelter planet is going on with the rapid development in science and technology. The other thing that we should...
The society I am living is about 5 square kilometers in area. It takes probably an hour to go around. This society is just a small part of the city, and the city itself is a small part of the country. There are hundreds of such countries and thousands of such cities on the earth. I can't imagine how many hours or years will it take to visit around the earth.
The other day I was browsing some images of telescopic views of space. At...
South Korea has lost contact with its Naro-1 rocket, just 137 seconds after take-off. Officials believe the rocket exploded.
Korea Aerospace Research Institute (KARI) and Khrunichev State Research and Production Space Center had hoped to use a Naro-1, South Korea's first carrier rocket, to launch a STSAT-2B satellite.
South Korea had postponed the launch on Wednesday due to problems with the rocket's fire extinguisher system. Science...
Chinese researchers have successfully built an electromagnetic absorbing device for microwave frequencies. The device, made of a thin cylinder comprising 60 concentric rings of metamaterials, is capable of absorbing microwave radiation, and has been compared to an astrophysical black hole (which, in space, soaks up matter and light).
The research published June 3 in New Journal of Physics (co-owned by the Institute of Physics and German...
