From theory to reality, graviton-like particles are isolated in laboratories.

ScitechDaily reports about this thing like this: "A team of scientists from Columbia, Nanjing University, Princeton, and the University of Munster, writing in the journal Nature, have presented the first experimental evidence of collective excitations with spin called chiral graviton modes (CGMs) in a semiconducting material". (ScitechDaily, From Theory to Reality: Graviton-like Particles Found in Quantum Experiments)  There are four fundamental forces or interactions.  1) Strong nuclear force. (Strong Interaction) 2) Weak nuclear force (Weak Interaction) 3) Electromagnetism. (Electromagnetic interaction) 4) Gravity (or gravitation) (Gravitational interaction) Their transportation particles are bosons.

New ultra-fast processors break Moore's law.

"Artistic image of the new inspection tool for ultrafast electronics with femtosecond electron beams. Credit & Copyright: Dr. Mikhail Volkov, edited" (ScitechDaily, Bridging Realms: Unveiling the Future of Electronics at Terahertz Speeds) New photonic microprocessors are faster than nobody expected. The photonic microchips along with femtosecond electron beams make it possible to create a new way to make microchips. And that brings a new way to create fast and secured long-distance data transmissions. But those microchips are so fast that we can say that Moore's law is broken in the photonic networks. The speed of photonic networks and photonic processors is so high. That makes those systems faster than regular processors. Even if there are fewer transistors in the system. The difference between photonic, and electric networks is that photons don't cause so much heat, and because photonic processors can use double frequency in light, that makes it independent from

Quantum gravity is the key to larger-scale gravity models.

Quantum gravity is the gravitational effect between the smallest known particles. Understanding quantum gravitation requires that all other effects be stripped off. So that researchers can measure the gravitational effect between subatomic particles.  There is the gravitational effect between protons and neutrons, as well as, the gravitational effect affects things like electrons and their movement around nuclei have gravitational effect. But the other three natural forces or interactions cover that gravitational effect below them.  Electromagnetism and weak-, and strong nuclear forces cover the gravitational effect between electrons and an atom's nucleus. Quantum gravity is different than full-scale gravity because the object's size is far smaller. And there are also other power fields than just gravitational fields.  The gravity is wave movement like all other fundamental interactions. And that causes ideas that at the quantum level, there could be something that can reflect

How long can life exist in the universe?

That's a good question. When we think about life, we must realize that the autonomous factories that use robots to collect raw materials can also be things that can fill the description of life. In that case, life is the living or non-living creature that can multiply and defend itself. Robot factories can operate quite independently, and their intelligence level is not probably higher than some cells or bacteria.  In that case, those independently operating factories can be remnants of past civilizations. But the thing is that the robots that have genetically cloned living brains can be as intelligent as humans or even more intelligent than we are. In those cases large number of living brains control the spacecraft that involve Von Neumann technology. And they can make copies of themselves.  So are those systems living or dead? Those brains need nutrients anyway. And that means those systems can be an ultimate hybridization. Between machines and living creatures. That kind of andr

Researchers think that the multiverse is not fiction anymore.

Multiverse means that our universe is one of many universes. The reason why researchers and scientists believe that this is true is that logical. About 50 years ago people didn't know that there were other solar systems. Exoplanets were only theories in the 80's.  About 400 years ago people thought that our Sun was the only star in the universe. Edvin Hubble proved that our galaxy, Milky Way is one of many galaxies. Then researchers found that galaxies form groups, and supergroups. That means that today we think that the universe, where we live is the ultimate supergroup of galactic supergroups. And logically thinking there should be other universes. We believe that the universe began its existence in an event or series of events called the Big Bang. That event did not begin, because the energy that formed material should come from somewhere. The Big Bang was not one "bang" or explosion. It was a series of events where material took form. Or the energy level that it h

Quantum breakthrough: stable quantum entanglement at room temperature.

"Researchers have achieved quantum coherence at room temperature by embedding a light-absorbing chromophore within a metal-organic framework. This breakthrough, facilitating the maintenance of a quantum system’s state without external interference, marks a significant advancement for quantum computing and sensing technologies". (ScitechDaily, Quantum Computing Breakthrough: Stable Qubits at Room Temperature) Japanese researchers created stable quantum entanglement at room temperature. The system used a light-absorbing chromophore along with a metal-organic framework. This thing is a great breakthrough in quantum technology. The room-temperature quantum computers are the new things, that make the next revolution in quantum computing. This technology may come to markets sooner than we even think. The quantum computer is the tool, that requires advanced operating- and support systems.  When the support system sees that the quantum entanglement starts to reach energy stability. I

The new tiny accelerators can make a revolution in many technologies.

"Illustration of a shoebox-sized accelerator. An electron source and buncher/injector feeds into a sub-relativistic DLA (the device described in this article), which accelerates electrons up to 1MeV in energy. These electrons are further accelerated by SiO2 waveguide-driven relativistic DLA, and finally pass through an undulator to produce coherent free-electron radiation.

This system makes it possible to create new materials. And one of the purposes of this kind of particle accelerator is to shoot ions into diamond structures. This system can shoot other atoms in ion form in carbon structure because ions can push carbon atoms away from their route in diamonds. That makes it possible to make diamond-based quantum computers.  Tiny particle accelerato

The diamonds are impressive qubits.

"A recent study has introduced a potent combination of diamond and lithium niobate for quantum technologies, achieving a remarkable 92% light transmission efficiency. This advancement promises to enhance the development of quantum computing and communication networks." (ScitechDaily, Redefining Quantum Possibilities: Scientists Develop Diamond-Lithium Niobate Chip With 92% Efficiency) The idea in diamond qubits is that there are some different atoms in the diamond's carbon structure. Those different atoms like nitrogen, boron, or some noble gas can turn into the part of a diamond using electromagnetic radiation. The idea is that those boron atoms can used to make the quantum entanglement in that diamond. In some visions, the high-class light handling capacity makes it possible for the entire diamond or carbon atoms in it to turn into the quantum entanglement network. That makes this system the most powerful solid qubit in the world.  "Figure 1: Lower right: Structura
