...it's not energy you can release like a bomb.

Yet supernovae are the biggest 'bombs' in the universe.

 

Sure you can: drop a piano on someone's head.

Energy is stored in the gravitational field, though it's many orders of magnitude weaker than the binding energies of the nuclear fields.

Still not a 'bomb'.

You can transmit gravitational energy as a possible weapon of destruction using a gravity field if the curl of the vector field is not zero across the object. It's just not something you can easily carry like a bomb because it requires massive objects moving rapidly closely like neutron stars or black holes in a death spiral.

 

Still not a 'bomb'.

When asteroids hit earth, we measure the impact energy in terms of equivalent TNT. Seems pretty bomb-like to me.

 

Yet supernovae are the biggest 'bombs' in the universe.

Sure, the gravitational potential energy is converted into kinetic energy in a Core collapse supernovae but its the nuclear force (neutrino generation) that makes the bomb effect possible as the Coulomb barrier is broken.

Seems more like an inelastic collision to me.

And all that kinetic energy came from where? Oh yeah, the gravitational field.

I only said it can't be used as a Bomb (outside of supernova nucleosynthesis), not that gravitational energy doesn't exist in a gravity field.

 

well,I think studies about the origin of gravity wave could be useful only if it leads to know a more powerful force than nuclear power...to use as bomb or as a new propulsion.otherwise it doesn't make sense.
anyway ...for misusage of newly studied physic (or even metaphysic) rules,there seems to be always ready syndications watching our minds :\

"This award ensures that NSF's LIGO, which made the first historic detection of gravitational waves in 2015, will continue to lead in gravitational-wave science for the next decade," said Anne Kinney, assistant director for NSF's Mathematical and Physical Sciences Directorate, in a statement. "With improvements to the detectors—which include techniques from quantum mechanics that refine laser light and new mirror coating technology—the twin LIGO observatories will significantly increase the number and strength of their detections. Advanced LIGO Plus will reveal gravity at its strongest and matter at its densest in some of the most extreme environments in the cosmos. These detections may reveal secrets from inside supernovae and teach us about extreme physics from the first seconds after the universe's birth."

In contrast to previous searches, in which new gravitational wave detections were kept hush-hush until scientists were ready to publicize them, new detections will be announced with immediate public alerts. That way, any astronomer will be able to search for possible light produced in the aftermath of the convulsions, potentially leading to new scientific discoveries.

LIGO is back at it. Having just turned back on after months of upgrades on 1 April, the Laser Interferometer Gravitational-Wave Observatory has already spotted another pair of black holes colliding.

It's too bad the whole article is not available for the general public.

It’s a clash of the titans. The Laser Interferometer Gravitational-Wave Observatory (LIGO) has spotted the signs of yet another enormous collision in space, and this one seems to be between a black hole and a neutron star – the first time we’ve observed the two massive objects together.

 

I think this is it.

“With the Coatli we had a chance to observe the gamma-ray flash just 20 seconds after it occurred. The time doesn’t depend on the Mexican research equipment but on the time it takes to send the satellite signal to our email that gives the order to the telescope to monitor a certain area in space. This is the problem that we cannot solve,” Rosa Becerra explained.

The new signal likely represents the instant that the two black holes merged. The merger created an even more massive black hole, of about 142 solar masses, and released an enormous amount of energy, equivalent to around 8 solar masses, spread across the universe in the form of gravitational waves.

The LIGO/Virgo collaboration have by now detected the mergers of ten black hole binaries via the emission of gravitational radiation. The hypothesis that these black holes have formed during the cosmic QCD epoch and make up all of the cosmic dark matter, has been rejected by many authors reasoning that, among other constraints, primordial black hole (PBH) dark matter would lead to orders of magnitude larger merger rates than observed.

 

It should be mentioned that in understanding the QCD science field. Color is not color.

 

Gravitational waves detection is accelerating:

[]... scientists predict that there is also an ambient murmur of subtle, low-frequency ripples constantly flowing through everything in the universe, including Earth. Now, researchers think they’ve found a candidate signal after more than a decade of watching fast-spinning collapsed stars for the faintest sign of a discrepancy that might indicate a wave.
