Nanosatellites are the next-generation tools in military and civil work.

It's possible that around the Earth flies even millions of nano-size satellites. Those systems can be about the cell phone size systems that form clouds that can make recon and other missions. Nanosatellites can use as an entirety. They can focus their extremely-small cameras on one point. And that gives them very high resolution. 

The nanosatellites can boost communication. But they can do many more things than offer over 1GB data transmission capacity between orbital devices and ground stations. They can act as next-generation multipurpose systems that give the high-power ELINT capacity for recon satellites. Or they can act as a large entirety that can observe Earth with extremely high accuracy.

The nanosatellites can observe larger satellites. That means they can follow them and search for their condition. Or the nanosatellite can observe data transmission of larger satellites. The nanosatellites are hard to detect because they are very small and nanosatellites can look like space junk. 

The nanosatellites can host very small biological laboratories. Or they can grow crystals inside them. And those cheap satellites can return to Earth after they have done their missions. 

"Spire Global, in partnership with ESA, has launched a second pair of satellites designed to communicate with each other securely using light-based optical inter-satellite links. These satellites will demonstrate the ability to transmit more than 1 GB of data securely within a short window of direct visibility, over distances equivalent to 5000 km, similar to the distance from Glasgow to New York.

The nanosatellites can act as the extremely large radio telescope. In that case, the satellites are looking in different directions. And when those satellites see something interesting they can turn their antennas to the same point. And that thing makes it possible to use those satellites as extremely large radio telescopes or radar antennas. 

Because those satellites are forming a cloud and each satellite can operate independently destroying those spaceborne drone swarms is not an easy operation. The radar satellites can focus their radio transmitters on one target and form an electric arc that destroys the targeted satellite. 

The nanosatellites are giving ultimate ASAT(Antisatellite) and ABM (Antiballistic missile) capacity to owners of those systems. When those satellites' IR sensors detect a missile launch or hostile satellite, the AI can drive them to impact course to those targets. Also, nanosatellites can protect larger satellites against ground-launched or airborne-launched ASAT systems. The idea is that the nano-size satellite can impact incoming ASAT weapons. And destroy them or push them out of the course. 

In some extreme visions, the nanosatellites are connected by using the net of some strong fibers. Or maybe they use laser rays that are strong enough that they can cut those missiles into pieces or damage their aerodynamics. The idea is that those satellites can make that net at the front of the incoming ABM mass raid, and that can cause damage to those missiles. The damaged nose of the warhead can cause the situation. That the warhead breaks into pieces when it returns to the atmosphere before its detonators operate.

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...

Spinning cylinders prove a 50-year-old physics problem.

"Scientists at the University of Southampton have experimentally proven the Zel’dovich effect by amplifying electromagnetic waves using a spinning metal cylinder, confirming a theoretical prediction from the 1970s and opening new avenues in technology and quantum physics. Credit: SciTechDaily.com" (ScitechDaily, 50-Year-Old Physics Theory Proven for the First Time With Electromagnetic Waves) "“Colleagues and I successfully tested this theory in sound waves a few years ago, but until this most recent experiment, it hadn’t been proven with electromagnetic waves. Using relatively simple equipment – a resonant circuit interacting with a spinning metal cylinder – and by creating the specific conditions required, we have now been able to do this.” (ScitechDaily, 50-Year-Old Physics Theory Proven for the First Time With Electromagnetic Waves) Researchers amplified electromagnetic waves using spinning metal cylinders. That experiment proved the Sunyaev–Zeldovich, SZ effect, is v...

What makes it hard to create a room-temperature superconductor?

"The discovery of wave-like Cooper pairs in Kagome metals introduces a new era in superconductivity research, offering potential for innovative quantum devices and superconducting electronics, driven by theoretical predictions and recent experimental validations. Credit: SciTechDaily.com" (ScitechDaily, Kagome Metals Unlocked: A New Dimension of Superconductivity) "Superconductivity is a set of physical properties observed in superconductors: materials where electrical resistance vanishes and magnetic fields are expelled from the material. Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered, even down to near absolute zero, a superconductor has a characteristic critical temperature below which the resistance drops abruptly to zero. An electric current through a loop of superconducting wire can persist indefinitely with no power source" (Wikipedia, Superconductivity) Theoretically, a superconducting electric circu...
