Time reversal photons play a big role in quantum circuits.

Photon is timeless. And that makes photons an excellent data storage. But the problem is that the information that is stored in photons must be protected against outside effects. But photon-based data storage is quite easy to make. The system must just trap one photon into it. In the systems that stop photons. Photons are stored between electron orbitals. And that makes the practical system quite complicated to create. The reason for that is that electrons disturb lasers that make quantum entanglement for connecting those photons.

The laser system must make quantum entanglement between that stopped photon to transport information to the quantum computers. Stopped photons also can use in quantum computers to transform binary information to quantum mode. The system drives information into the frame and then the photon in the middle of the chamber will superposition and entangle. That kind of system can make it possible to create the next-generation photonic quantum circuit.

The ability to stop photons makes it possible to send them to the future or the past. The system can stop photons and then pump or remove energy in and out of those photons. That thing adjusts time dilation and makes it possible. That system can transport information over time and space.

In quantum mechanics time is reversal. And information is always preserved. That means. Theoretically, objects can go back in the past, and take information. And come back to the future. Same way objects can travel to the future and then return to the past. Time dilation is the key element in that thing. Time dilation means that time is like a river that travels outside the object.

When an object's energy level is high, time passes more slowly relative to that object. When the energy level of an object is low, the time or river outside the object travels faster relative to the object.

We must realize that. When time dilation would slow the speed of time in some systems. The system travels to the future, or its particles are aging slower. When time travels faster in the system, the system would travel black in time or the aging of particles is faster. We know we can make time dilation by pumping energy to the object. And removing energy from the object means that the aging of the particles is faster.

"A team of researchers from the University of Twente has successfully illustrated that quantum mechanics and thermodynamics can coexist by using an optical chip with photon channels. The channels individually showed disorder in line with thermodynamics, while the overall system complied with quantum mechanics due to the entanglement of subsystems, proving that information can be preserved and transferred.

The photon has no time. That means there is a possibility. To send photons to the future by pumping energy to it. And the same way researchers can send photons back to the past by removing energy from it. The problem is how to transfer energy from the past to the future. The Quantum entanglement requires that the energy level in the transmitting part is higher. So because of the cosmic expansion the energy level in the past is always higher than in the future. And photons have lower energy levels in the future.

The problem with time reversal in complex quantum systems is free energy. When the energy level in the system increases it slows the aging of the particle. The problem is that when energy pumping ends the particle sends extra energy as an energy pulse. That energy pulse rips material into pieces.

There is a possibility that the rotating energy fields of the atoms make it possible to send also complicated quantum structures to the past and the future. The problem is that the energy or quantum field rotation must happen in a way that the system can conduct extra- or free energy out from it in a way that will not break the system.

And then remove the free energy from the system. The only problem is the standing wave inside atoms or free energy that rips them into pieces. And that's why time reversal is made in single- or two-photon systems.

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger. The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth. It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons. It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho...

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials.
