Gravitational waves

GRAVITATIONAL WAVES NEWS

In general, a black hole is a region in Space where the pulling force of gravity is so strong that neither matter nor light can ever escape.

Why merger of two black holes, 100 times bigger than the Sun, holds significance

July 18, 2025 12:51 pm

The detection of gravitational waves from this event has generated a lot of scientific interest. It has the potential to refine the current understanding of black hole formation, the evolution of stars, and, possibly, the current models of the universe itself.

On May 20, the full-scale Engineering Development Unit Telescope for the LISA (Laser Interferometer Space Antenna) mission, still in its shipping frame, was moved within a clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, US.

Gravitational waves detected from black hole collision event 800 million years ago

June 23, 2020 10:41 pm

The gravitational signal from this merger event travelled for 800 million years through the universe and arrived at the network of two advanced-LIGO detectors – at Hanford, Washington and Livingston, Louisiana, USA and the advanced-Virgo detector in Cascina, Italy, in the wee hours of August 15 2019, just past 2.40 am IST.

Gravitational waves from unequal mass black holes detected

April 21, 2020 10:47 am

Named GW190412, the merger was collectively detected on April 19, last year. The highly-sensitive signals were detected using Laser Interferometer Gravitational wave Observatory (LIGO) and Virgo, located in the US and Italy, respectively.

Gravitational waves leave detectable mark: Study

May 10, 2019 10:11 pm

Gravitational waves -- ripples in the fabric of spacetime -- leave behind plenty of "memories" that could help detect them even after they have passed, according to a study.

Four new gravitational waves detected from black hole mergers

December 05, 2018 5:25 pm

The position of the binary black holes, located by the LIGO and VIRGO observatories, were spotted 2.5 billion light-years from Earth, and identified with a precision of 39 square degrees.

Signs of supermassive black hole mergers found

October 29, 2018 2:53 pm

Gravitational wave telescopes have been able to find evidence of the merging of smaller black holes since 2015, by measuring the strong bursts of gravitational waves that are emitted when binary black holes merge.

Albert Einstein's gravity theory passes extreme test: Study

July 08, 2018 3:30 pm

Einstein's understanding of gravity, as outlined in his general theory of relativity, predicts that all objects fall at the same rate, regardless of their mass or composition.
