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 ..

Scientists detect New Source of Gravitational waves

Scientists have detected gravitational waves produced by collision of neutron star and black hole for the first time. Highlights Gravitational waves ripples were detected in fabric of space-time. This finding shows that there are neutron star-black hole systems. This system will help in answering several questions regarding cosmos ranging from star formation to expansion rate ..

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 ..
