The new methods can make compact GWD (Gravitational Wave Detectors) possible.

The next-generation gravity wave detectors can be more sensitive and compact than ever imagined. In some scenarios, the nano-size mirrors with as high a reflection as possible can create an optical structure. Where the laser ray's length is thousands of kilometers. This thing is quite hard to make. 

If researchers create that structure using mirrors that reflect 100%. The system can detect the brightness of laser rays. And when the gravity wave hits those laser rays, it changes their brightness. 

But the other thing is what if researchers can stretch light? In stretching light the length of the light surface is big. And that makes it possible to create a system. That can detect gravity waves

The Kerr-enhanced magneto-optical springs can make the next-generation gravity wave detectors (GWD)


But then we can imagine the case that the sensor uses the magneto-optical springs. In some ideas, the magneto-optical spinning structures can harvest the gravity waves, if they are sensitive enough. The problem is that gravity waves are so weak. Gravity waves must impact enough energy to the sensor that it can detect changes in its structure. 

The GWD sensors are the newest tools for the research universe. Those things offer the possibility of researching black hole's internal structures. 

The detectable gravity waves are forming in the black hole's event horizon. But their origin is far inside the event horizon. That means that black holes are like an onion of multiple internal gravity fields. 

All gravitational objects send gravity waves. Those things can also used to give information about the internal structures of other objects. But the problem is how to create GWD that has high enough accuracy. Gravity wave detectors are tools that give information about the most dominating force in the universe. 


Can we someday benefit from gravity waves as an energy source? 


The GWD sensors can also work as pathfinders for the systems that use gravity waves as an energy source. The sensor that measures gravitational waves harvests energy from those waves. Gravity waves can transfer energy to photons. Those things are interactions. And photons should also transfer energy to the gravity waves. 

So large-scale systems could use laser rays to capture gravity waves. Or gravity waves could transport energy to some lightweight, low-energy particles. And then laser rays can block the gravity waves. That thing makes those particles like free gluons or low-energy quarks deliver their extra energy. And maybe someday, we can make those gluon clouds.

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...
