According to media reports, the first detection of gravitational wave devices now open again to explore the universe of corrugated trip, laser interferometer gravitational wave observatory (LIGO) began in January of this year to stop work for equipment upgrades, now all the instruments back online, gravitational waves continue to search the depths of the universe. LIGO in February 2016 for the first time announced the detection of gravitational waves, second times in June to detect gravitational waves. The two detected gravitational waves are caused by the collision and fusion of the black hole. Scientists at the California Institute of Technology, said that since January this year, the performance of engineers and scientists of LIGO were evaluated, and the laser pointer, electronic circuit and optical equipment has been upgraded to enhance the sensitivity of LIGO.

Time and space ripple is like a shock to the drum surface, these ripples for scientists to study the universe opens a new perspective, and it is possible to reveal the invisible feature of the universe.

Detection of gravitational waves is likened to "hear" the voice of the depths of the universe. Time and space ripple is like a shock to the drum surface, these ripples for scientists to study the universe opens a new perspective, and it is possible to reveal the invisible feature of the universe. Some scientists believe that the discovery of gravitational waves has opened up a whole new field. LIGO scientists say that the LIGO probe into the mutual integration of the black hole is likely to not produce any light, so other observation equipment or telescope may not be observed at all.

LIGO scientist David Reitze said, by increasing the sensitivity of LIGO, and the longer the time of observation, we are likely in the future observed more black hole fusion phenomenon, deepen our understanding of the dynamics of the black hole. Although prior to this, scientists can through some indirect evidence to infer the existence of gravitational waves, but they cannot directly detect high power laser pointer, until September 2015, LIGO found this historic phenomenon, and for the first time announced in February 2016. Gravitational waves in space and time structure in the expansion, when the gravitational waves through the earth, LIGO will be formed at two points in the gravitational waves observed between the changes.

These changes are in fact very small, if the length of the LIGO detector extends from 4 km to 4.25 light years, they can be detected from a long distance to the change of the hair to the hair. LIGO team plan to enhance the sensitivity of the equipment in the future. LIGO has been collecting data since 2002, but has been unable to detect the signal until later on it was a major update, known as the LIGO Advanced program. At the end of January this year, the 30mw laser pointer mission is the first observation of the LIGO upgrade. LIGO Livingston Observatory director Giaime Joseph said that this year, LIGO of all the staff are focused on updating the observation equipment, and docking down a new round of observation is full of expectations.
