The square kilometer array produces data equivalent to twice the entire Internet traffic and 100 times the size of the Large Hadron Collider.
IBM is developing 3D chips to achieve the required computing power of a square kilometer array.
According to foreign media reports, the US IBM company is designing the strongest computers in history. The daily data throughput is equivalent to the entire Internet. It can be used to analyze the radio waves from space and explore the mysteries of the origin of the universe. The computer will be connected to an array of 1,900 square miles (about 4,920 km2) of telescopes, a square kilometer array, to analyze data obtained from the telescope. The square-kilometer array was able to observe the cosmic scene of 13 billion years ago. Shortly after the big explosion, it was the dawn of the universe.
IBM has designed the most powerful computer computing capability that is millions of times faster than current fastest PCs. The amount of data that is processed will reach 100 times that of the Large Hadron Collider. IBM R & D department of Tang. Emposon said: “The data acquired per square kilometer array is equivalent to twice the current daily Internet traffic of the world.†It is reported that the square kilometer array will be completed in 2024 and will be able to observe the cosmic scene of 13 billion years ago and will be used to Study the evolution of galaxies, the dark matter and the origin of the universe.
IBM will use 3D chips to build this computer to achieve the required computing power of the square kilometers array. The square kilometer array will have thousands of dish antennas installed, covering an area of ​​more than 1 square kilometre. The width of the entire array is equivalent to the continental United States. This telescope array has 50 times the sensitivity of any previous radio telescope and is 10,000 times faster than current telescopes. The number of data generated per square kilometer per day for a square kilometer array is estimated to be a few EB (Aibytes). After processing, the annual stored data is estimated to be between 300 and 1500 PB (patches bytes). In contrast, the annual output of the Large Hadron Collider produced by the European Organization for Nuclear Research is around 15 PB.
On April 3, the head of the Kilometre array project met in Amsterdam to discuss the specific construction site for this array of giant telescopes. It is reported that the array will have an area of ​​1900 square miles and is expected to start construction in 2016. Michael Van Haarlem, the interim general manager of the Square Kilometer Array project, said: "This telescope array will have a profound impact on our understanding of the Earth's position in the universe and will help deepen our understanding of the history and future of the universe. We believe that a series of major discoveries will be staged in the future."
Our understanding of the universe. Dr. Ian Griffin of the British Association for Science Exploration Center stated: “The square kilometer array project will provide astronomers with a brand new tool that will revolutionize our understanding of the universe. This array can be used on a large area of ​​space. The observations in the region reveal incredible galaxy details that help scientists study mysterious and exciting black holes and other objects to verify the theory of relativity and allow astronomers to learn more about the early history of the universe."
The scientific community believes that they can use the square kilometer array to determine whether there is life outside the solar system. Searching for life outside the system requires the use of breakthrough technologies. The square-kilometer array dish antenna is 15 meters in diameter and can detect electromagnetic radiation emitted by celestial bodies. They have incredible sensitivity and can find airport radar on a planet 50 light-years away from Earth. Dish antennas will be observed with the aid of low-frequency and medium-frequency aperture arrays. These arrays allow a square-kilometer array to have a wide field of vision and allow observation of multiple space areas at once.
The square kilometer array uses an astonishing length of cable that can orbit the earth for two weeks. At present, the location of the construction of this telescope array is still unknown. Both southern Africa and Australia are under consideration. Both regions have an environment suitable for observation by telescopes. The telescope must be able to get the clearest “line of sight†without electronic interference, such as interference from mobile phones. The square kilometer array is expected to begin construction in 2016 and the dish antenna will be put into use after 8 years. The array's prototype KAT-7 consists of seven 16-meter dish antennas and is currently being tested in the Karoo Desert, South Africa.
