The black holes’ sound proves one of Hawking's theorems.

When a black hole merger happens. Those things are spinning around each other before they impact. The black hole rings like a bell. And that proves one of Hawking’s theorems. When black holes collide or merge, that event forms the new black hole. The new black hole is more massive than those black holes, but it's less massive than the total mass of the merged black holes. That thing means that during a merger, black holes lose energy as gravitational waves. And that is one of the most interesting things in the universe. When a gravitational wave travels through the universe, it acts like all other wave movements. If there is a gravitational object, or an object with mass, in the path of gravitational waves, that object distorts those gravitational waves, because all objects with mass send those waves. 

“By analyzing the frequencies of gravitational waves emitted by the merger, the LVK (LIGO, Virgo, KAGRA, gravitational sensors) team was able to provide the best observational evidence captured to date for what is known as the black hole area theorem, an idea put forth by Stephen Hawking in 1971 that says the total surface areas of black holes cannot decrease. When black holes merge, their masses combine, increasing the surface area. But they also lose energy in the form of gravitational waves during the phenomenon. Additionally, the merger can cause the combined black hole to increase its spin, which leads to it having a smaller area. The black hole area theorem states that, despite these competing factors, the total surface area must grow in size.” (ScitechDaily, Scientists Finally Hear Black Holes Ring, Confirming Hawking’s Famous Prediction)

That thing can help determine the source of dark energy. Dark energy means. Free energy that increases entropy, and increasing entropy. Increases the power that we see as the cosmic expansion. So, in the case of dark energy, we should ask, what releases that energy?

Or what puts energy into moving? There is a possibility that the soúrce of that energy is in some kind of cosmic voids. Those voids can be like holes. In some energy fields, they can accelerate and stretch wave movement. When wave movement falls in the cosmic void. It should stretch. Because the scattering effect and resisting fields turn weaker. When that wave movement impacts the opposite side in the cosmic void, that turns the wave movement shorter. And this is why the position. Where we are is important. 

If we are living in a cosmic bubble, that means the bubble distorts wave movement. That bubble or void also makes the particle’s evaporation faster than outside the bubble. Because the energy level in the bubble is lower than outside it, that means matter turns wave movement faster than outside it. 

There is a theory. That we are in a cosmic bubble. That bubble can have an effect. On the measurements. When we think about the black hole merger. Those events can form bubbles. In things like gravity fields. The model is based on the wave movement features. If the very thin but strong wave movement field travels across the field, where the wave movement’s wavelength is the same, the stronger field takes the lower energy field with it. When a black hole merger happens, those black holes release their energy in the form of gravitational waves. 

Those gravitational waves can form a bubble that pushes the gravitational field away from the merger. That kind of gravitational bubble can make the “empty” gravitational waves. When that bubble collapses. Gravitational wave impact in the middle of it. And that makes the event look like a vacuum bomb. The impacting wave movement that reflects from the middle of the collapsing bubble. Can put energy into moving. And maybe these kinds of bubbles can explain dark energy and gravitational waves. 

Gravitation affects the field that takes particles with it. That means when the field travels in the bubble. And reflect from inside, that thing makes those bubbles or voids act like particles. When a particle starts to spin with a very high speed, it collects energy into its whisk-shaped shell. That shell forms so-called superstrings. When a particle spins, it collects energy fields from around it. Or it transforms that field into kinetic energy. Those superstrings collect the field from around them. And some part of that field falls into the middle of the particle. And then that field or waves reflect from the center of that particle.
