Flying wings are coming.

Chinese H-20 and the USAF B-21 stealth bombers are both flying wings. The flying wing design makes those aircraft more economical. And they can carry more payload. Also, the economical flight makes them fly longer time before refueling. And along with stealth technology that makes those bombers very capable for global operations. 

The thing is that those aircraft can be very fast because they are aerodynamically very capable. Their shape is smooth. And the curves are soft. That allows the radio waves from the radars to slide over their body without causing an echo. The same way that shape makes air molecules travel over the bodies of those aircraft. 

There is the possibility that the magnetic field around those aircraft is boosting the stealth capacity of those super bombers. The magnetic stealth system acts as the Earth's magnetic field and pushes the radio waves away from the aircraft. The idea is that the radio waves pass that object without reflection. And that makes those aircraft invisible to radars.

The speed of stealth bombers is limited because the super- or even hypersonic flight causes sonic booms. The air cone of the supersonic flight makes those aircraft easier to detect. So the optimal speed of the stealth bomber is about Mach 0,9 or high subsonic. But there is the possibility that those aircraft have AI-based systems that limit the speed subsonic when those aircraft operate in stealth mode. 

There is the possibility that when stealth bombers are moving to operational areas they use afterburners or even ramjet or scramjet engines. Then the pilot just turns one button to "stealth" mode and then the system limits the speed of the stealth bomber that it flies at subsonic speed. There are only a few details published about those highly classified bombers. 

In the future, stealth bombers can jump out of the atmosphere and make so-called ballistic jumps. That allows them to move fast to operational areas. And there, those bombers can turn to use stealth mode while they are searching for enemies from that area.

Schrödinger's cat: and the limits of that idea.

"In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition". (Wikipedia, Schrödinger's cat). But the same thing can use as model for many other thought experiments.  Sooner or later, or at least in the ultimate end of the universe, the Schrödinger's cat will turn into wave movement. The information that this cat involved exists but the cat does not exist in its material form. The information doesn't ever vanish. It just turns its shape.  We are all trapped in the universe and time. The universe is the space that is entirety to us. There are no confirmed other universities. But the multiverse is a logical continuum for the expanding galactic megastructures.  The problem with natural things is this. They are black and white. They exist or do not exist. Could there be something, that exists and not exists at the same time?  Scrödinger's cat is thinking experiment about case their cat is not dead or not alive. But in this...

The string theory offers a new way to calculate Pi.

"Scientists discovered a new series for pi through string theory research, echoing a 15th-century formula by Madhava. By combining Euler-Beta Functions and Feynman Diagrams, they modeled particle interactions efficiently. Credit: SciTechDaily.com" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Leap in Mathematics) People normally think that. The pi is the ratio of the circumference circle's circumference to the circle's diameter. The Pi is a mathematical constant 3.14159..., the endless decimal number. The Pi is interesting because developers can use that decimal number to make the encryption algorithms stronger.  The idea is that the encryptions program hides the message's original ASCII numbers by multiplicating those numbers with some decimal number. Or the system can add some numbers to those ASCII numbers.  "Aninda Sinha (left) and Arnab Saha (right). Credit: Manu Y" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Le...

There are always more than three actors in the real world.

"An international research team is advancing precision timekeeping by developing a nuclear clock using thorium isotopes and innovative laser methods, potentially transforming our understanding of physical constants and dark matter. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Unveiling the Thorium Nuclear Clock and Its Time-Twisting Secrets) From Three-body problem... There are no pure three-body systems in nature. There are always more than three components in the system. For making real three-body systems we must separate those three bodies from the environment. Otherwise, there are stable effects. But nobody can predict some effects like distant supernova explosions or sun eruptions.  And one of those things that affect all bodies is time. When radioactive materials decay. That affects the stability and symmetry of the object.  Energy levels affect the existence of things like neutrons. The thorium atom clocks are next-generation tools for time measurement....
