Einstein is invincible. However, there are a few problems with spacetime models.

Can dark energy be the same as Hawking radiation? 

It's possible. When researchers measure things like gravitational lensing. They just forget that black holes make fields and materials denser than usual. Maybe researchers don't remember that near black holes other energy interaction than just gravity is also stronger. Or maybe there can be some structure that reflects energy back from structures near or even inside the black hole's event horizon. The Hawking radiation is the thing that ever measured. And for making precise models researchers must know the entire system. 

The source of dark energy is unknown. We know that black holes send gravity waves. But could it also send Hawking radiation and could dark energy and Hawking radiation be the same thing? People sometimes mix the terms gravity wave and dark energy. Gravity waves are waves in energy fields. Their source is in gravity centers. Dark energy is wave movement with an unknown source. 

That question is: can theoretical Hawking radiation be the dark energy? If that thing is true that means the black hole turns or transforms energy and material into dark energy. We know that dark energy is the wave movement that source is unknown. But because dark energy interacts with material it should interact with a black hole. The black hole should make the dark energy denser and it should change its route. So that means. Gravitational lensing should work with dark energy and dark matter. 

Above Gravitational lensing. 

When we think about spacetime and gravity, we say there is a pothole around gravitational centers.  That means there is something that pulls energy and material into the endless pothole, there it cannot flee. So, we can say that the gravity centers like black holes are endless potholes that will not fill. The problem is this. Where do those black holes put energy and material that fell into them? 

Theoretically, that energy should blow the black hole away. The problem with Einstein's models is that during his lifetime nobody knew that things like black holes existed. And the second thing is that dark energy and dark matter were not even predicted during Einstein's lifetime. The black hole must put energy, wave movement, and materials that it pulls inside it somewhere or it blows away because its internal power wins gravity. 

We can think that gravity is negative energy because it pulls material into the black hole. The energy that falls into a black hole impacts other energy waves at least at the center of a black hole trying to break out from that monster. So theoretically is possible that the black hole forms an energy level that breaks its structure. The singularity is the thing that forms a black hole. 

That means material where all particles and quantum fields form one entirety. But to keep its form that massive structure requires an outcoming energy field. The energy field presses the structure. And if it's gone, the energy flow starts to travel out from singularity. And sooner or later that massive structure turns into wave movement. But even black holes just turn energy and material into another form. 

In the same way, material is one form of energy. And a black hole is the only thing that can interact with dark matter. And there is introduced a model. Where a black hole turns material into dark matter. Or it can pull material to the spaghetti-shaped structure. But then we can think about the black hole's structure. 

Lasers can block the light itself. So could there be a structure around the black hole that blocks some other energy forms? Theoretically is possible that maser-emission or the ability to turn wavelength coherent and block other waves is universal to all wave movement types. That means also dark energy and gravity can turn coherent and then block other waves with same wavelength. So could it be possible that some energy form cannot fall into the black hole?

In some models, there are strings just in the middle of a black hole. If those energy strings or superstrings are long enough, that means they pull energy out from black holes. The idea is from the string theory, where energy forms strings, Those strings can be even billions of light years long. And the material is one form of those strings. 

And that means if those strings exist they can pull out energy from the black hole. Those theoretical superstrings can be hollow and even if a black hole can pull them inside, those superstrings can hang out from a black hole for millions of years before that monster can pull them inside it Because energy travels to the lower energy level. Those hypothetical strings can pull energy out of the black hole. 

A black hole is like a pothole in spacetime. When material and energy fall into them through the event horizon the point, where escaping velocity reaches the speed of light there are no observations about that information. But before material and energy fall into a black hole they follow the spiral-shaped trajectory. 

And just before the event horizon is the ring of material. In some interesting visions, one photon can turn into the ring. That surrounds the event horizon. That ring interacts with its environment and pumps energy into that gravitational pothole.  

But then we can see that structure in another way. We can say that if the energy ring orbits the pothole it could send energy waves over that pothole. 

And that energy can block the same wavelength fields to drop into the black hole. The idea is the same as the thing where laser light blocks light itself. If there is a so-called energy lid around the black hole we can ask what energy that thing removes. Is it possible that there is no energy form in the black holes? 

The black hole is a pothole in space-time. It's possible that the pothole that forms gravity channels is not smooth. In some models, there are waves in its shells. Those gravity waves or gravitational lumps in that pothole can cause the strength of the gravitational field will not grow symmetrically. Or maybe there is a thin, string-shaped structure where the side-coming energy pushes power. If that string is almost straight or its wavelength and frequencies are very small. Measurements of that string are a very difficult operation. Because. A black hole's radiation covers that string's existence.
