Here is the news.Chinese scientists are working to set up the world&`&s highest altitude gravitational wave telescopes in Tibet. The move aims to detect the faintest echoes resonating from the universe, which may reveal more about the Big Bang.Construction has begun for the first telescope, code-named Ngari No.1, in Ngari Prefecture. The telescope, located 5,300 meters above sea level, will detect and gather precise data on gravitational waves in the Northern Hemisphere. It is expected to be operational by 2021.The following phase will involve a series of telescopes, code-named Ngari No. 2, to be placed at 6,000 meters above sea level.The budget for the whole project is estimated at 130 million yuan, roughly 19 million U.S. Dollars.Ngari is known for its clear skies and minimal human activity, thanks to its high altitude. The prefecture is one of the world&`&s best spots to detect tiny twists in cosmic light.The Ngari observatory will be among the world&`&s top primordial gravitational wave observation bases, alongside the South Pole Telescope and the facility in Chile&`&s Atacama Desert.Gravitational waves were first proposed by Albert Einstein&`&s theory of general relativity 100 years ago. But it wasn&`&t until last year that scientists announced proof of the waves&`& existence, spurring fresh research interest around the globe.China has announced its own gravitational wave research plans, which include the launch of satellites and setting up FAST, a 500-meter aperture spherical radio telescope in southwest China.This is Special English.U.S. president Barack Obama&`&s tweet following his farewell address to the nation has become the most popular post on the presidential account.Obama tweeted from the POTUS account, saying "Thank you for everything. My last ask is the same as my first. I&`&m asking you to believe-not in my ability to create change, but in yours."As of midday, the message had been retweeted more than 500,000 times. Twitter spokesman Nick Pacilio says it outperforms his previous top tweet, a message posted after the Supreme Court&`&s June 2015 decision to overturn state bans on gay marriage.The POTUS account has more than 13 million followers.

Norway has begun shutting down analog radio technology, making it the first country in the world to phase out the FM signal for national and some regional broadcasting.The FM signal was switched off in January in one of its districts in favor of Digital Audio Broadcasting, or DAB.The switchover was performed by a radio listener who moved a lever to drum rolls and a countdown from the audience at a public library in northern Norway. The listener said she had been listening to FM radio for more than 70 years.Norway gradually switches to digital, and the shutdown process is due to be completed by Dec. 13.The Norwegian government has cited its landscape with deep fjords, high mountains and scattered communities for making it expensive to operate FM networks. Norway&`&s Parliament made the decision in May 2011.It will save the country an estimated 200 million kroner, roughly 23 million U.S. dollars.This is Special English.The annual Consumer Electronics Show has been held in Las Vegas in the United States.
