The gravitational wavesThe astronomical phenomenon that occurs when two hypermassive objects, such as black holes, collide violently, has recently shaken the basis of physical knowledge. And it is that the LIGO observatories, in the United States; Virgo, in Italy, and KAGRA in Japan, detected the highest number of gravitational waves to date.
Experts are excited, as they believe that this finding can help solve the mysteries of space, such as the fundamental components of matter and the functioning of space and time.
“This is truly a new era for gravitational wave detection. It is a breakthrough in our quest to uncover the secrets of the evolution of the universe,” he said. Susan Scott, Researcher at the Center for Gravitational Astrophysics at the Australian National University and one of the authors of the study.
They ran into a tsunami of gravitational waves
The researchers detected 35 new gravitational waves between November 2019 and March 2020, of which 32 are the result of collisions between pairs of merging black holes, and three correspond to collisions between neutron stars and black holes. That’s why Scott said they ran into a “Tsunami of gravitational waves”.
There are already 90 gravitational waves that have been detected between 2015 and 2020. However, this discovery has to be reviewed by other teams, but most experts consider that this information is very promising.
What are gravitational waves?
When cosmic objects move or collide, they create a ripple in the fabric of space-time, which stretches space-time in one direction and compresses it in the other. The first scientist to predict this phenomenon was Albert Einstein, in 1916, but it was until 2015 that the first detection of a gravitational wave was achieved. The researchers consider that gravitational waves allow us to have a broader view of the universe.
