Gravitational lensing and twist in the universe’s expansion.

“Timing delays in quasar light bent by massive galaxies offer a fresh way to measure the universe’s expansion, and the results deepen the rift between early- and late-universe estimates. This growing tension may be a clue that something fundamental about cosmic physics is still undiscovered.

When there is a difference between observations and theoretical models, it means. Something is missing from the model. The missing thing. It might be the fifth force or some other large-scale effect. Like a spinning megastructure. Because the material is not homogeneously spread. Through the universe. That means its effects are not homogeneous. The just-found megastructures are like strings throughout the universe, and they should cause interactions. That slows large areas in the universe. 

Things like previously unknown high-energy reactions can also cause unpredictable effects in the universe. When GRB or CRB injects energy into particles, they will not deliver that energy straight away. They glow or. Deliver energy for a while. 

Those megastructures can also form a maser effect inside them. That means. They will collect energy into those massive structures. Like. Metal tubes do. When a magnetic field forms inside it by rolling an electric wire around that tube. Those megastructures act like all other tubes. But they are far larger. So, they might have a stronger electromagnetic effect than previously thought. 

The previously unknown megastructures can cause a need. To re-estimate cosmological principles. An extremely. A large megastructure. It can have a gravitational effect on large parts. Of the universe. Those spinning megastructures that can close chains of galactic superclusters. Inside them can cause previously unknown interactions in some areas of the universe.  That means the universe’s expansion speed might not be the same everywhere

The universe’s expansion is slowing. Or, is it? The question is about the Hubble constant, which is thought to be 73 km/s per megaparsec (km/s/mpc). But in some new measurements, the Hubble constant is slowing down to 67 km/s/mpc. But there is also a possibility. The expansion of the universe. It is not the same everywhere. This means that. There are masses. That. We don’t know in the universe. If something slows the expansion of the remarkable part of the universe, that thing must be very massive. The thing that slows the expansion can be in the universe. Or, outside the universe. Or something else. The expansion of the universe depends on many things. Like, cosmic voids. 

And the differences between quantum field energy levels. Those things cause energy flows. That can have. An unexpected, powerful effect on the universe’s expansion. If. The effect’s area is large enough. It can have. An effect. On the entire universe. There are observations. The universe’s expansion. This is not in line with a young universe. The reason. For It. It can be that the radiation and temperature in the young universe. It was higher than in the modern universe. But that universe caused a stronger redshift in space around it. 

Nobody expected that. Objects were close to each other, and they caused redshift between each other. We can think. About things. Like merging black holes. Those black holes stretch radiation also between them. In the young universe, the scattering effect was stronger. And this caused the idea that the young universe needed. To have components. That is unknown. Some quite common particles. In the young universe. Exist in the modern universe. In very high-energy areas. Also, those exotic particles existed longer in the young universe. This can cause measurement mistakes. If. We use models. Those were made for the modern universe.

It’s possible that the hypothetical fifth force is not a new force. It might be some previously unknown interaction between known natural forces. And, maybe EM-fields. If the model doesn’t fit the system, it means something is missing. 

Gravity and light interact. In the same way, new observations show. Electromagnetic fields can also have. A stronger interaction with light. Than predicted. This means the fifth force might not be some new force. It might be a previously unknown interaction. “Scientists have recently discovered an interaction between an electromagnetic wave and its own magnetic component as it passes through a material, updating a 180-year-old assumption that only accounted for the interaction between light and its electric field.” (Science Alert, A 180-Year Assumption About Light Was Just Proven Wrong)

“This phenomenon, the Faraday effect (FE), was first described in 1845 by Michael Faraday, providing some of the earliest evidence of interaction between magnetism and light waves.”(Science Alert, A 180-Year Assumption About Light Was Just Proven Wrong)

“It describes how a beam of light passing through a transparent material is affected when that material is subjected to a magnetic field. Specifically, this changes the direction of polarization of that light beam.”(Science Alert, A 180-Year Assumption About Light Was Just Proven Wrong)

For a simplified perspective, light can be unpolarized or polarized. When light is unpolarized, its electromagnetic oscillations occur in various directions (perpendicular to its plane of travel).”(Science Alert, A 180-Year Assumption About Light Was Just Proven Wrong)

So can some other interaction. Between photons and light remains unknown. Another thing is that. If some particles travel out from the universe faster than the main material. That means those particles can decay or vaporize throughout the universe. This means that those particles release energy, which pushes the universe or even large megastructures back. 

The light and its interaction with gravity mean that the light. Will not necessarily travel on straight routes. Gravitational lenses bend light. Also, things like string gravitational fields can stretch light. This causes an unexpected redshift. Things like cosmic voids can also cause an effect. The wave movement that travels into those voids can jump back from its center. The universe is full of cosmic voids. That means. Those voids can collect and reflect energy. In the same way. Spinning megastructures.  It can bind energy into them. When those megastructures spin, that spin binds energy. And those megastructures can have a large-scale effect on the universe. The previously unknown structures and interactions can affect things. Like, the Hubble constant.
