Ripples in Space and Time detected for third time
The Laser Interferometer Gravitational-wave Observatory also known as LIGO of Louisiana detected gravitational waves for the third time. These waves were produced from collision or merging of two black holes. These ripples in space time fabric confirmed that there is too much to explore in space than we thought it used to be. With every new detection , they are getting more information about the behaviour of these mysterious gravitational waves.
The spokesperson of Ligo Scientific Collaboration quoted.
We have further confirmation of the existence of stellar-mass black holes that are larger than 20 solar masses. These are objects we didn’t know existed before LIGO detected them. It is remarkable that humans can put together a story, and test it, for such strange and extreme events that took place billions of years ago and billions of light-years distant from us.
The entire LIGO and Virgo scientific collaborations worked to put all these pieces together.”
LIGO is working on this from a very long time and they are happy to see the results. It opened a new window in astronomy. LIGO made the first-ever direct observation of gravitational waves in September 2015 during its first observing run since undergoing major upgrades in a program called Advanced LIGO. The second detection was made in December 2015. The third detection, called GW170104 was made on January 4, 2017. It described in a new paper accepted for publication in the journal Physical Review Letters.
located 1.3 and 1.4 billion light-years away, respectively.)
The newest observation also provides clues about the directions in which the black holes are spinning. Pairs of black holes spiral around each other. They also spin on their own axes — like a pair of ice skaters spinning individually while also circling around each other. Sometimes black holes spin in the same overall orbital direction as the pair is moving — what astronomers refer to as aligned spins — and sometimes they spin in the opposite direction of the orbital motion. What’s more, black holes can also be tilted away from the orbital plane. Essentially, black holes can spin in any direction. “Black holes” which were once thought to be hypothetical are now studied extensively by scientists. They contain answers related to dark matter and energy, exotic matter and even time travel .
Clearly , this new study is important in many aspects as we will see the impacts in near future. LIGO has proved that their observatory is responsible for advancement in revealing dark side of the universe. We may be able to detect Collisions of two neutron stars (if these are massive black holes are formed ) with the help of LIGO soon…
