Lhasa, Jan 7, 2017: China is working to set up the world’s highest altitude gravitational wave telescopes in Tibet Autonomous Region to detect the faintest echoes resonating from the universe, which may reveal more about the Big Bang.

Construction has started for the first telescope, code-named Ngari No.1, 30 km south of Shiquanhe town in Ngari Prefecture, said Yao Yongqiang, chief researcher with the National Astronomical Observatories of the Chinese Academy of Sciences, Xinhua news agency reported.

The telescope, located 5,250 meters above sea level, will detect and gather precise data on primordial gravitational waves in the Northern Hemisphere.

It is expected to be operational by 2021.

Yao said the second phase involves a series of telescopes, code-named Ngari No. 2, to be located about 6,000 meters above sea level. He did not give a time frame for construction of Ngari No. 2.

The budget for the two-phase Ngari gravitational wave observatory is an estimated 130 million yuan ($18.8 million). The project was initiated by the Institute of High Energy Physics, National Astronomical Observatories, and Shanghai Institute of Microsystem and Information Technology, among others.

Ngari, with its high altitude, clear sky, and minimal human activity, is said to be one of the world’s best spots to detect tiny twists in cosmic light.

Yao said 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 2016 that scientists with the Laser Interferometer Gravitational-Wave Observatory announced proof of the waves’ existence, spurring fresh research interest among the world’s scientists.

Hawking treated Artificial Intelligence as threat to humanity

Hawking's theory lies upon the assumption that the universe has no boundaries

  • Stephen Hawking passed away on March 14th, 2018
  • He treated AI always as a threat to humanity
  • There were many arguments he presented to support his point

Award-winning physicist Professor Stephen Hawking, who died on Wednesday, always warned against Artificial Intelligence (AI) and its growing dominance over humanity.

“Earth is becoming too small and humanity is bound to self-destruct, with AI replacing us as the dominant being on the planet,” he told wired.com in November 2017.

There are many good uses of AI, but it can be misused too.

“I fear that AI may replace humans altogether. If people design computer viruses, someone will design AI that improves and replicates itself. This will be a new form of life that outperforms humans,” Hawking said.

The theoretical physicist kept on saying in the past that that developments in AI have been so great that the machines will one day be more dominant than human beings.

He noted that a new space programme should be humanity’s top priority “with a view to eventually colonising suitable planets for human habitation”.

“I believe we have reached the point of no return. Our earth is becoming too small for us, global population is increasing at an alarming rate and we are in danger of self-destructing,” Hawking warned.

In 2016, at the opening of Cambridge University’s AI centre, Professor Hawking said that AI could either be the best or worst invention humanity has ever made. Earlier in March, the renowned British physicist said there was nothing around before the Big Bang.

Speaking during a TV talk show “Star Talk” on National Geographic Channel, Hawking propounded his theory on what happened before the universe came into existence. Hawking’s theory lies upon the assumption that the universe has no boundaries. During the show, Hawking argued that before the Big Bang, real ordinary time was replaced by imaginary time and was in a bent form.

“It was always reaching closer to nothing but didn’t become nothing,” he said. Further, Hawking drew an analogy between the distorted time with Ancient Greek philosopher Euclid’s theory of space-time, a closed surface without end.

Taking the example of Earth, he said: “One can regard imaginary and real-time beginning at the South Pole … There is nothing south of the South Pole, so there was nothing around before the Big Bang.”

“There was never a Big Bang that produced something from nothing. It just seemed that way from mankind’s perspective,” Hawking said, hinting that a lot of what we believe is derived from a human-centric perspective, which might limit the scope of human knowledge of the world. IANS
