STATES CHRONICLE – Scientists intend to use gravitational waves detection to find out more about the evolution of the Universe. A year ago researchers used LIGO to prove Einstein’s theory regarding the existence of gravitational waves in deep space. LIGO is the Advanced Laser Interferometer Gravitational Wave Observatory.
After completing that experiment, Professor Archana Pai, a member of the Indian Institute of Science Education and Research (IISER) who was also part of the team of scientists back then, claimed that Indian officials support the idea of installing a LIGO detector in India. If researchers managed to set up a LIGO, then they may increase the possibility of detecting and analyzing gravitational waves.
Prof. Archana Pai noted that there were recorded subtle noises which indicate the existence of gravitational waves, but they still need sensitive equipment to prove their existence. Installing LIGO detectors might help scientists have a palpable proof. Pai also pointed out that researchers are developing further analysis and observations of the algorithmic data provided by LIGO detectors in Hanford and Louisiana.
On Saturday, February 11, Prof Archana Pai presented a paper on gravitational waves at a program marking the International Day of Girls and Women in Science. She argued that gravitational waves detection are bound to help scientists prove several theories regarding space and time, deciphering the mysteries of the universe’s evolution.
Prof Pai explained how she together with a team of researchers tested and examined gravitational wave information and revealed that the data was consistent with the General Theory of Relativity of Einstein. Back in 1916, Einstein predicted the fact that accelerating masses are bound to emit gravitational waves. Unfortunately, scientist needed centuries actually to prove that theory.
On September 14, 2015, researchers conducted the LIGO experiment where the detectors helped them record gravitational waves which occurred in the collision of two black holes. Before merging with one another, one of the black holes was 29 times bigger than the Sun, and the other one was estimated to be 36 times larger than our Sun. After the collision, in the process, they lost three solar mass energy.
The massive black hole that formed had a mass 62 bigger than the one of the Sun. This discovery was announced only this year, on February 11 after researchers verified the data.
