The technology what makes the mobile telephones 3D-scanners is actually the same, what is used to make 3D maps of Earth and other planets. In that technology satellites use radars and meters range between satellite and planet, what makes possible to make those maps, and modern computers and radars allow to make high-resolution 3D-maps, what can be zoom in very good accuracy.


By using VLF or ELF  (Very or Extra Long Frequency) radars those satellites can make 3D maps from the ocean floor from the orbital trajectory. Same way ships can make 3D maps from the ocean floor, by using sonar systems. Also, Lidar or laser radars can be used in those mapping operations. Blue-green laser radars can scan very deep areas of the oceans, and that equipment can also meter the altitude and length of the waves.


But now I missed the thing, what I suppose to write. If the mobile telephones would be connected to drone-helicopters, and they could use enough sharp GPS-system, they could be used to scan very large areas. Of course, the system must know only the distance between the target and phone, and GPS is the very good tool to check the position of the telephone. But it could also work with triangle metering. The changes between the position of the drone and perfect circle can be the addition or subtract from the perfect circle.


That equipment works like satellites, but they are much smaller. And they can scan even entire buildings or ships by using their SONARS. So this might be new role fort smart telephones, what can now use in many things. And if that telephone would cover with waterproof cores and underwater drones it can use to scan entire fish, atolls or shipwrecks. Also, intelligence services can use those things to make 3D-models of submarines. Only thing what is necessary is that SONAR signal must pass the core.

The anomalies in gravity might cause dark energy.

"Physicists at UC Berkeley immobilized small clusters of cesium atoms (pink blobs) in a vertical vacuum chamber, then split each atom into a quantum state in which half of the atom was closer to a tungsten weight (shiny cylinder) than the other half (split spheres below the tungsten). (ScitechDaily, Beyond Gravity: UC Berkeley’s Quantum Leap in Dark Energy Research) By measuring the phase difference between the two halves of the atomic wave function, they were able to calculate the difference in the gravitational attraction between the two parts of the atom, which matched what is expected from Newtonian gravity. Credit: Cristian Panda/UC Berkeley" (ScitechDaily, Beyond Gravity: UC Berkeley’s Quantum Leap in Dark Energy Research) Researchers at Berkeley University created a model that can explain the missing energy of the universe. The idea is that the particles and their quantum fields are whisk-looking structures. Those structures form the superstrings that are extremely thi...

When the most advanced tool becomes the enemy of advance.

Why... Above this text is the image that is not made by using AI. I took that image yesterday evening. That thing required a little bit of trouble and time. Walking into that point, taking my cell phone, and taking that picture took time. When I looked at that picture I realized why people use AI in many things. AI offers easy things to get the job done. That easy tool allows people to make thousands of lines of code in minutes.  That is possible if the person uses some code libraries. And that makes a person effective. But that thing is not good for advancement and innovation. Also, that way of making programs is not good for data security. If some hackers get those code libraries that allow them to break the systems those codes are used.  We know that thing. But we ever ask why person makes that thing? Why does that person use libraries and copy-paste? Why that person uses code, that somebody gave to the hard disk? The answer is this something forces a person to make things ...

Neon and time crystals can be the new tools for quantum computing.

"New research investigates the electron-on-solid-neon qubit, revealing that small bumps on solid neon surfaces create stable quantum states, enabling precise manipulation. This research, supported by multiple foundations, emphasizes the importance of optimizing qubit fabrication, moving us closer to practical quantum computing solutions." (ScitechDaily, Quantum Riddle Solved? How Solid Neon Qubits Could Change Computing Forever) Researchers created a superposition in solid neon. And those neon ions, where the system creates superposition in their surfaces.  Making it possible to manipulate those atoms. The atom-based qubit has one problem. Orbiting electrons cause turbulence in their quantum fields. The thing that can solve the problem is to use the quantum fields for the superposition.  If the system can position electrons at a certain point, it can make a small hill to the atom's surface. And the system can use that thing for making quantum superposition between the mos...
