If the giant plasma ball surrounds the universe. The radiation that comes into the universe causes annealing. The universe is like a bubble in an electromagnetic vacuum. And that thing means that the radiation travels outside the universe faster than inside the universe. But why that thing causes the expansion of the universe?

The reason for that is that the material is denser in the universe. The radiation pushes against material and quantum fields when it moves the particles. If there are no quantum fields and material the radiation cannot push against something. The denser material causes the pushing effect from inside the universe is higher.

The universe is full of magnetic fields. The strongest of them are surrounding things like neutron stars and black holes. But some of those magnetic fields are extremely weak. The fact is that even if something in the universe is weak, that doesn't mean that the thing is without effects. Distances and dimensions in the universe are far larger than in the laboratory.

The thickness of our galaxy's material disk is 700 ly. And the Milky Way's diameter is 200 000 ly. The radio signal travels through our galaxy vertically for 700 years and horizontally 200 000 years. That means the time that even the weakest effect would have a long-term influence on the radio signal. So in the universe, the weak effect can be very long-term. And that thing is one of the remarkable things that we must realize in the universe.

Interaction is one of the things that are causing the problems. Things like super heavy black hole Sagittarius A in the center of our galaxy might seem insignificant. But we must remember that the entire galaxy spins around Sagittarius A. That means the Sagittarius A has the dominant effect on our galaxy and everything around it. But we have very hard to notice that effect.

The things like planet Jupiter are covering the flow around Sagittarius A. The same thing causes finding other universes is extremely difficult. Proving the multiverse theory requires observations of another universe. And that means the shine of galaxies and plasma is covering the shine from another universe. The effect is similar to streetlights. That is covering the shine of the stars.

The multiverse theory is one theory that seems very true with the big probability. But proving that theory is extremely difficult.

In that case, the local effect is stronger than the larger effect. And that is the thing that makes the observation of the universe quite difficult. The reason for that is we are in the universe. The fact is that we are also in the galaxy called Milky Way. So, we might believe that Milky Way is an extremely large thing. Its dimensions are impressive.

But if we would fly and compare the milky way with the size of its local galactic group we can think that our galaxy is a very small thing.

Same way, when we are comparing the solar system's size with the size of the Milky Way we might think that our solar system is smaller than the pin end.

And still, we must travel for over a year to our closest neighbor planets. The light and radio signals are traveling to Mars in many minutes. The radio signal travels 11 minutes from Mars to Earth.

But when we are thinking about the shape of the universe as the plasma ball, and where is the layer, we must remember one thing. If the entire universe has a common magnetic field that magnetic field affects the plasma bubble. That surrounds the entire, visible material. That thing means that there could be some kind of axle-looking ray that is forming poles to the plasma bubble.

And if all galaxies are traveling in the same direction. That means there is some kind of gravitational center in the universe. But observing a plasma ball is extremely difficult. The brightness of the stars and galaxies are covering that bubble behind them.

In that case, the cosmic magnetic fields are formed by the dynamo-effect of the plasma that surrounds the hypothetical gravitation center. The magnetic fields in the universe are a mystery. Some of them are around neutron stars.

But theoretically, there is the possibility that the plasma bubble around the universe sends radiation inside the universe. When radiation hits that giant plasma core it makes it anneal. And the annealing causes the situation that the particles are starting to send radiation.

Black holes cause a virtual redshift because gravitation stretches the wavelength near them.

At the beginning of this text is a film about the redshift of black holes. Gravitation stretches light, and that means gravitation fields are pulling waves longer. That thing is called the gravitational redshift. As you can see from the film, the black hole stretches radiation and distorts the redshift. Gravitational redshift, or virtual redshift, means that a black hole might seem to be at a longer distance than it is. The film shows the redshift of the star that orbits a supermassive black hole. But all other black holes interact the same way. The event horizon is always constant. At that point, the black hole's escaping velocity is the same as the speed of light. So every black hole interacts basically in the same way. And it's possible to apply that model to all black holes irrespective of their size. Is gravitation the thing that forms dark energy? That thing seems somehow strange. But when photons and other particles are traveling through the ball that forms the visible

The shape of the brain means more than neuro connectivity.

Well, we might say that the brain is in its entirety. Another thing is that all things in the brain have some kind of purpose. The shape of the brain and, especially, the folding of the brain shell are extremely important things. Those folds are expanding the brain's surface areas. And the brain shell has a primary role in the thinking process. The surface area of the brain determines how large the cerebral cortex is. And in a large cerebral cortex, there are a large number of neurons. But as I just wrote, the brain is in its entirety. "Researchers have discovered that the shape of a person’s brain significantly impacts thought, feeling, and behavior, overturning the prevailing emphasis on complex neuronal connectivity. Utilizing MRI scans and the principle of eigenmodes, they found that brain function is closely linked to its geometric properties, much like how the shape of a musical instrument determines its sound, offering new avenues for exploring brain function and diseas

New nanomaterial is 4 times harder than steel. And, at the same time 5 times lighter than steel.

New nanomaterial is 4 times harder than steel. And, at the same time 5 times lighter than steel. The new material is the hollow glass fiber with DNA molecules inside that structure. Or as you see from the image. The glass fibers are on both sides of the DNA. DNA molecule is the thing, that involves the genetic code of the cells. Genetically engineered cells can make DNA, and those molecules can used as the nanomaterial's structures. DNA manipulation makes it possible to create new types of extremely strong materials. And those materials are stronger than steel and lighter than it. DNA molecules can act as nano-size springs. And in some visions, genetically engineered cyborg cells like cyborg macrophages can make extremely long DNA molecules. And then they can just use those molecules as spears that can pierce wanted cells. Or those cyborg cells can also dumb targeted cells full of the DNA that terminates them immediately. The DNA and nanotube combinations can also act as DNA-b
