Dream of 15 min. towns. Can we make everything in 15 minutes?

Everybody knows the dream of 15 min. towns. In those towns, every service is 15 minutes trip away from home. But can we escalate that dream? Could 15 minutes city or 15 minutes urban area involve the idea that every service will happen in 15 minutes?

How realistic this model that everything happens in 15 minutes is? And could the most modern technology turn the global environment into 15 minutes entirety, where people can reach everything on Earth in 15 minutes?

That means we would go to the doctor in 15 minutes. We are waiting for the doctor for 15 minutes. And then we spent 15 minutes in the examination room. After the doctor, we go to the drugstore in 15 minutes and after 15 minutes. We have medicines in our hands. Could that thing be possible someday? We can call that vision the 15 minutes society. Everything happens in 15 minutes.

When we are building taller buildings. The reason for that is that price of land is high in urban areas. And we can make hybrid solutions for an environment where people are living in smaller areas. And shopping centers are connected to houses where people are living. That makes the use of time more effective.

And when those complexes are ready that solution decreases emissions. But the problem is that people might not ever go outside. And in the most extreme dystopic visions, those shopping-center-home hydrides are turning to independent states.

Maybe shopping centers are the service centers of tomorrow. And if the robots are making physical products people can work in the same building where they live and go shopping. There could also be things like public services like doctors. But of course, this kind of advancement means that people have fewer contacts with the outside world than ever before.

If we have the internet. We can click ourselves to another side of the Earth. Of course, we are not physically in there. But we can use VR screens that are giving us a real-looking vision of the environment. But the problem is that we are selecting information. We must not read things that do not please us. And that means we are missing the information that can be vital.

But can we travel physically around the world in 15 minutes? Or travel to any place on Earth in less than an hour?

When we think about things like hypersonic aircraft and hyperloop trains those things might transport us to any point on the Earth by using hypersonic transportation. New hypersonic systems use hydrogen fuel so they are not causing emissions. And the hypersonic VTOL (Vertical Take-Off and Landing) aircraft can take people to any location on the Earth in less than an hour.

But the "magnet loop" train could be a more powerful and faster transportation system than any other transporter invented before. The magnet loop is a particle accelerator that transports the train inside the vacuum tube.

The system uses magnetic levitation. And also magnets are pulling the train in that tube. Because there is a vacuum in the tube there is no friction. And that allows rising the speed of that system to be highly hypersonic. That kind of system can make it possible to make a new type of transportation that is faster than any atmospheric system before it.

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
