Chinese scientists are proposing a space gravitational wave detection ( Albert Einstein Theory ) project that could either become a part of the European Space Agency’s evolved Laser Interferometer Space Antenna (eLISA) project or a parallel project,

LIGO finally discovered Albert Einstein’s discovery of gravitational waves

The discovery of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory in the U.S. on Thursday, Feb. 11, has encouraged scientists around the world, including China, to accelerate research. Gravitational waves are tiny ripples in the space-time fabric caused by violent astronomical events.

The report said that a group of scientists from the pre-research group at the Chinese Academy of Sciences will finish drafting a plan for a space gravitational wave detection project by the end of this year and submit it to China’s sci-tech authorities for review.

According to the report, the Taiji project has two alternative plans. One is to take a 20-percent share of the European Space Agency’s eLISA project, and the other is for China to launch its own satellites by 2033 to validate the European Space Agency (ESA) project.

“Gravitational waves provide us with a new tool to understand the universe, so China has to actively participate in the research,” Hu Wenrui, a prominent physicist in China and a member of the Chinese Academy of Sciences, said.

“If we launch our own satellites, we will have a chance to be a world leader in gravitational wave research in the future,” Hu added. “If we just participate in the eLISA project, it will also greatly boost China’s research capacity in space science and technology. In either case, it depends on the decision-makers’ resolution and the country’s investment.”

The report said that different scenarios will be included in the draft plan, with budgets ranging from 160 million yuan ($24.3 million) to more than 10 billion yuan.

“Although I am not sure which plan the decision-makers will finally choose, I think the minimum budget of 160 million yuan should not be a problem for China,” Hu said.

Under a cooperative mission, ESA and NASA launched the Laser Interferometer Space Antenna’s gravitational wave ( Albert Einstein Theory ) observatory to detect and observe gravitational waves. The project was proposed in 1993, which involved three satellites that were arranged in a triangular formation and sent laser beams between each other.

The report said that after NASA withdrew from the project due to a budget shortage in 2011, the LISA project evolved into a condensed version known as eLISA.

On Dec. 2, ESA launched the space probe LISA Pathfinder to validate technologies that could be used in the construction of a full-scale eLISA observatory, scheduled for launch in 2035.

“Currently, all the operating gravitational wave detection ( Albert Einstein Theory ) experiments worldwide are ground observatories, which can only detect high-frequency gravitational wave signals,” said Wu Yueliang, deputy president of the University of the Chinese Academy of Sciences. “A space observatory, without any ground interference or limitation to the length of its detection arms, can spot gravitational waves at lower frequency.”

On Feb. 11, gravitational waves ( Albert Einstein Theory ) caused by two black holes merging about 1.3 billion years ago were detected and confirmed by scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the U.S. The report said it was the first time that the elusive phenomenon was directly detected since it was predicted by Albert Einstein 100 years ago.

Now considered the most advanced ground facility for gravitational research, LIGO includes two gravitational wave detectors located in the rural areas of Washington and Louisiana states in the U.S.

“Metaphorically speaking, if the research into gravitational waves is a symphony, the discovery of the LIGO experiment makes a good prelude by proving that the hypothetical wave does exist,” said Hu. “But I believe the other movements will mostly be composed of new discoveries from space observatory devices, because the low and middle band–which can only be detected from space–is the most extensive source of gravitational wave.”

It will jointly be piloted by the department of atomic energy and department of science and technology. “The project will motivate Indian students and young scientists to explore newer frontiers of knowledge, and will add further impetus to scientific research in the country”, said the statement.

The two US-based underground detectors — known as the Laser Interferometer Gravitational-wave Observatory, or LIGO for short — played a crucial role in the historic detection of gravitation waves. One is located in Hanford, Washington and the other in Livingston, Louisiana.

The machines that gave scientists their first-ever glimpse at gravitational waves are the most advanced detectors ever built for sensing tiny vibrations in the universe.

“The major gravitational wave research program in China is the cooperation with eLISA, which is led by Professor Hu Wenrui,” Li told Guangdong’s Nanfang Daily.

“The reason that eLISA made progress rather slowly was that the member states in Europe held different opinions as to whether gravitational waves exist,” Li added. “Now this has been proved to be true, which will greatly accelerate the pace of research in and out of China.”

Now one composer has reimagined the star signals from over a billion years ago as music

“The idea is that when you get a planet that is very like Earth, then the melody the algorithm generates is very nursery rhyme-like with small intervals, but if you get a planet like Jupiter with different characteristics, the sounds will turn out bizarre.”

Up next, Jeffes, Nissanke, and Desert will be working with Marshmallow Laser Feast to bring their music to life audio-visually. A virtual reality experience will, for example, allow users to feel like they are directly seeing and listening to the gravitational waves. “We want to make it work on an interactive level,” said Jeffes.
