Gravitational Waves Current Affairs, GK & News
Gravitational Waves
Gravitational Waves were for the first time discovered in February, 2016, 100 years after they were hypothesized by Albert Einstein in 1916. These waves were detected by the scientists working at two LIGO (Laser Interferometer Gravitational-wave Observatory) facilities in United States. LIGO scientists detected these gravitational waves produced by collision of two black holes located ..
What is Hum of the Universe?
The Hum of the Universe was recently detected by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). According to the researchers, the hum was produced by gravitational waves. About the Hum of the Universe The Hum of the Universe comes from a type of dead star called a “Pulsar”. These stars are basically neutron ..

LIGO detects first merger of two unequal-mass black holes
The scientists of Laser Interferometer Gravitational Wave Laboratory (LIGO) have recently recorded the first merger of black holes that were of unequal masses. On April 12, 2020, the LIGO-Virgo collaboration detected collision between two black holes that were 2.4 billion light years away. The scientists have now concluded from their researches and analysis that these ..

LIGO: Second Merger of Neutron Stars detected
The LIGO (Laser Inferometer Gravitational-wave Observatory) detected gravitational waves due to collision of two neutron stars. This is the second time the gravitational waves are being detected. Highlights The mass of the neutron stars detected is expected to be 3.3 times and 3.7 times as that of the sun. The scientists believe that the neutron ..
