The hypernova is an even more violent case than a supernova.

"Shock breakout of hypernovae: Hypernovae are even more violent astronomical phenomena than supernovae, with explosion energies exceeding those of supernovae by more than ten times. These powerful explosions are typically accompanied by strong jets that create distinct shock breakout structures at the poles of the star. The jets not only drive the explosion but also induce intense fluid instabilities within the ejected material, further mixing the star’s internal substances. Recent observational data has suggested that the famous supernova 1987A may be closely related to a jet explosion, rather than exhibiting the spherical explosion predicted by previous one-dimensional models.

The description of the hypernova is this. Hypernova is supernova that produces 10^48 J energy. The star that forms a hypernova has over 30 times the sun's mass. That energy load forms when extremely heavy stars collapse. 

The energy level. That hypernova release is 100 times more than the Type II supernova release. When hypernovas explode. They form some of the heaviest particles in the universe. All novas, supernovas, and other explosions form elements. 

The energy level determines how heavy particles those explosions can create. That makes those violent eruptions and collisions interesting. When we think about things like stones of wisdom that turn all material into gold the kilonova is the thing that can turn hydrogen into gold in the real world. 

The shockwave from impacting neutron stars presses the molecular cloud around the neutron stars. That pressure presses atoms with so high power that they turn into new elements. So, we can say that the soundwave from the impacts of those extremely dense objects forms a sound that forms new elements in space. 

Supernova and hypernova form new elements in the three stages. 

1) When a star starts to collapse density and temperature in its structure start to rise. That forms the heavy particle fission. The supernova. Or hypernova forms energy also in the shockwave that travels speed that is 99% of the speed of light. 

2) A shockwave from that reaction starts to travel out from the star at 99% of the speed of light. That presses atoms in interplanetary clouds around the stars together. That reaction forms new elements. It also releases energy. But that energy production is very short term. 

3) Shockwave forms a short-term cosmic void that collapses. That collapse pushes all material and energy into one point. That point forms singularity. So those explosions or eruptions form black holes and neutron stars in the explosions that look like vacuum bombs. 

The collision between neutron stars is different than a super- or hypernova explosion. When neutron stars collide, there is no internal energy production in those objects. The hyper- or supernova explosion happens when lots of star material fusion at the same time. 

The main energy producer in hypernova explosions can be the Nickel isotope 56 Ni. The energy level rises so high, that an impact wave or shockwave travels out from the star with 99% of the speed of light.  

The super- or hypernova forms heavy elements in fusion reactions as well as in shockwaves. The hypernova is more powerful than the supernova. And it always forms heavier elements than in lower-energy supernovas. The violent eruption always forms black holes.
