Gravitational lensing can uncover dark matter.



“Artist’s impression illustrating how wave-like density patterns produced by ultralight dark matter could warp space and alter the path of light from a distant source. As the light travels past the lensing object on its way to Earth, it follows a distorted path shaped by the surrounding mass distribution. The reflective sphere symbolizes the still-unknown nature of dark matter. The image was created using 3D computer graphics software.

Distant quasars can prove that dark matter acts like waves. And if the mythical WIMP is a quantum-sized black hole. That explains gravitational waves. This means that the graviton is a WIMP. That missing graviton boson is just the traveling quantum-sized black hole. This means that. When. Those quantum-sized black holes travel through the universe. They bind energy from around them. And that can explain why gravity is so special. 

Dark matter can bend light. And that can make it possible to see the WIMP. Dark matter is a mystery. It is a gravitational effect with an invisible source. Some galaxies seem to have less dark matter than others. That tells us dark matter can be denser in some areas. And less dense. In some other areas. How dense could those dark matter nebulas be? Nobody knows. Could dark matter form black holes in a very dense energy field? It should. 

Have the ability. To form a black hole. If. Dark matter particles interact through gravity. They should. Have the ability. To form black holes. The black hole doesn’t just pull matter inside it. Its energy also pushes particles away.  So if WIMPs (Weakly Interacting Massive Particles) are quantum-sized black holes. Their halos could have a stronger push effect. Compared. With the event horizon size. than so-called “regular” black holes do. 

The only fact that reseachers know about that strange phenomenon is this. Dark matter. Has gravitational interaction with visible matter. There are. Many things that dark matter could be. In some visions, dark matter is a particle. 

Inside some other particle. And if the particle spins very fast. That spin forms the quantum vacuum around the particle. 

When quantum fields from around the particle try to fill that point. That. Increases the pull of the particle’s gravitational field. When wave movement travels through that microvacuum. That microvacuum stretches it. Its wave movement becomes longer. 


Another version of that model is that Dark matter could be quantum-sized black holes. 


There is also a model. That dark matter is the cosmic minivacuums. Those microvacuums form when very high-energy particles travel outside the galaxy. When. Those particles travel out from the galactic halo. 

They suddenly go into a very low-energy space. This makes them release energy very fast. That forms a cosmic microvacuum. This acts like a particle. 

If. Particles like photons or electrons form outside the galaxy supercluster. They travel faster than they can travel in the supercluster. They release their energy into the plasma. That connects galaxies in the supercluster. And that forms the radiation. 


In some other models, dark energy and dark matter are connected to the universe’s expansion.


There could be a denser plasma wave at the outer border of the universe. That plasma formed when the Big Bang sent an energy wave into the universe. When. That energy wave traveled through space. There formed whirls in that energy. Those whirls turned into the first electrons and later quarks. 

Today, the expansion of the universe forms similar but lower-energy whirls behind that borderline of the universe. There. Could be cosmic microvacuums just inside the plasma wave. And when particles go into that microvacuum, they evaporate. 

If. We think that most of the matter in the universe is at the outer border of the universe. So. The border of the universe is heavier than the internal areas. If. Most galaxies are in that border. 

That means the border sends energy into the universe’s internal areas. There, that energy reflects. And pushes the outer border outward. If the outer border of the universe. Particles also escape from the universe. In that case, those particles also evaporate. They send radiation. And subparticles back to the universe. Those particles impact the universe’s borderline. And they travel faster. Than. They should. 

When those particles impact the universe. They. Must release their kinetic energy. This forms Cherenkov radiation in the universe. That radiation forms when quarks or some other particles hit the border of the universe. The same thing happens inside the plasma wave. But. When a particle evaporates inside that plasma wave. All energy and subparticles can escape from the universe only through that plasma border.

How does the fifth image form in the Einstein Cross?



“A mysterious fifth image inside a rare Einstein Cross exposed a massive halo of dark matter, giving astronomers a rare chance to study both the distant galaxy and the invisible structures shaping the cosmos. (Artist’s concept.) Credit: SciTechDaily.com” (ScitechDaily, Astronomers Spot “Impossible” Fifth Image Unlocking Dark Matter Secrets)

“The Einstein Cross (Q2237+0305 or QSO 2237+0305) is a gravitationally lensed quasar that sits directly behind the centre of the galaxy ZW 2237+030, called Huchra's Lens. Four images of the same distant quasar (plus one in the centre, too dim to see) appear in the middle of the foreground galaxy due to strong gravitational lensing. This system was discovered by John Huchra and coworkers in 1985, although at the time they only detected that there was a quasar behind a galaxy based on differing redshifts and did not resolve the four separate images of the quasar.” (Wikipedia, Einstein Cross)

The reason why the fifth image is possible. The thing. That is, the gravitational lens is a quasar. This is a straight line just behind the galaxy that the gravitational lens will make those four images. The distance to the galaxy is about 400 million ly. And the distance to that quasar is 8 billion light-years. 

The fifth image formed in Einstein Cross is of a supermassive object. In the middle of the image. Pulls radiation back in  focus. This means there is a galaxy that turns light into the form where radiation forms the four images of the single galaxy. The mass that focuses radiation forming that fifth must be between the galaxy (or in this case, quasar) and the observer.

So, there is an object between the distant galaxy and the Earth. The thing that observers cannot see about the object makes it interesting. Can it be some kind of dark matter formation, or maybe there is some kind of black hole between that distant galaxy and Earth? 

But if there is a supermassive black hole between Earth and that distant galaxy, why can't we see that black hole’s halo or the galaxy that should form around it? Of course, that halo can also be a quasar, but the problem is how the thing that forms the radiation cone can remain unseen? The quasar is behind the galaxy. It is in a straight line to Earth. The galaxy or the object that collects radiation into the fifth image is a straight line between Earth and that distant galaxy. 

There is a possibility that gravitational microlensing can also form the Einstein Cross. The gravitational microlensing. Means a black hole that is in our galaxy that bends light. All black holes act as gravitational lenses. In the case of a black hole, the term means a black hole that is at a certain distance from Earth. The microlensing is similar. But a smaller phenomenon. Than the full-size gravitational lensing. There is a possibility that planets. Or other, less massive objects can also form a gravitational lens. And in the case of planets, white dwarfs, and neutron stars. We can talk about microlensing. The neutron stars and planets with no atmosphere are excellent objects. To observe microlensing. In the cases of the stars. The atmosphere makes it hard to separate the gravitational lensing from the effect that the star’s atmosphere causes.

Could there have been UFOs in Earth's orbit in the 1950s?

Aligned, Multiple-Transient Events in the First Palomar Sky Survey could be artificial objects. Or. They could also be some light reflection...
