A group of scientists from the Laser Interferometer Gravitational-wave Observatory has detected a third gravitational wave.
Although the group first observed the phenomenon back in February, recently the researchers published their research in the journal Physics Review Letters. This marks a significant moment as Einstein predicted its existence more than hundred years earlier.
A senior astrophysicist at Northwestern University, Vicky Kalogera said, “Our handful of detections so far is revealing an intriguing black hole population we did not know existed until now.”
“Now we have three pairs of black holes, each pair ending their death spiral dance over millions or billions of years in some of the most powerful explosions in the universe. In astronomy, we say with three objects of the same type you have a class. We have a population, and we can do analysis.”
The latest discovery opens up window for further research in Astronomy as the discovery ultimately lead to black holes. By using the results from the latest findings, scientists now can learn black holes’ masses and other characteristics. Shane Larson from Northwestern University said, “Once again, the black holes are heavy. The first black holes LIGO detected were twice as heavy as we ever would have expected. Now we’ve all been churning our cranks trying to figure out all the interesting myriad ways we can imagine the universe making big and heavy black holes. And Northwestern is strong in this research area, so we are excited.”
The latest finding have even larger impact on the future researches related to black holes as it makes the possibility related to existence of binary black holes even stronger. Binary black holes are kind of black holes which exist in relationship with one another. Talking about the latest discovery, spokesperson of LIGO collaboration, David Shoemaker said, “We have further confirmation of the existence of black holes that are heavier than 20 solar masses, 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.”
We will need to wait long to understand the future of the study although the latest discovery has made studies related to space exploration even more interesting.
