For all its vast emptiness, the universe is humming with activity in the form of gravitational waves. Produced by extreme astrophysical phenomena, these reverberations ripple forth and shake the fabric of space-time, like the clang of a cosmic bell.

What would happen if a black hole fell into a wormhole?
Astronomers might detect black holes falling into wormholes via ripples in space-time called gravitational waves, a new study finds. Source: https://www.livescience.com/what-if-black-hole-falls-into-wormhole.html
‘Quantum negativity’ can power ultra-precise measurements
Scientists have found that a physical property called ‘quantum negativity’ can be used to take more precise measurements of everything from molecular distances to gravitational waves. …
Continuous gravitational waves in X-ray star systems—the search continues
Gravitational waves are ripples in space-time that come in many forms. So far, short-duration gravitational wave signals have been observed from colliding black holes and colliding neutron stars, but scientists expect to find other kinds of gravitational waves. Recently published research led by the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav)studied continuous waves: long-lasting gravitational waves, in this particular…
To find giant black holes, start with our solar system’s center
A new study from researchers at Vanderbilt University suggests that to find the most massive black holes, measure the effects of their gravitational waves on the flashes of light coming from pulsars. The best location to do that is at the precise gravitational center of the solar system. Source: https://earthsky.org/space/black-holes-gravitational-waves-pulsars-solar-system…
For the 1st time, a visible light explosion from a black hole merger
In recent years, black hole mergers in our universe have been detected via ripples in spacetime known as gravitational waves. Now, for the first time, astronomers believe they’ve observed visible light from a black hole merger, in a peculiar 3-black-hole system.

Researchers find the origin and the maximum mass of massive black holes
Through simulations of a dying star, a team of theoretical physics researchers have found the evolutionary origin and the maximum mass of black holes which are discovered by the detection of gravitational waves. Source: https://phys.org/news/2020-07-maximum-mass-massive-black-holes.html…
To find giant black holes, start with Jupiter
The revolution in our understanding of the night sky and our place in the universe began when we transitioned from using the naked eye to a telescope in 1609. Four centuries later, scientists are experiencing a similar transition in their knowledge of black holes by searching for gravitational waves.

Gravitational Waves Reveal Lightest Black Hole Ever Observed
sciencehabit shares a report from Science Magazine: Gravitational wave detectors have spotted a cosmic collision in which a giant black hole swallowed up a mystery object seemingly too heavy to be a neutron star, but too light to be a black hole. Weighing in at 2.6 times the mass of the Sun, the object falls into a hypothetical “mass gap,” a…
LIGO and Virgo find a mystery object in the “mass gap”
The science world is buzzing today about a new discovery made via the LIGO-Virgo collaboration. It’s a new object found in the so-called “mass gap” between neutron stars and black holes. Source: https://earthsky.org/space/gw190814-mystery-object-in-mass-gap…
