Is time an illusion?

Time is relative, said Albert Einstein. And that is the only real fact about time. Things like time as dimension or time as wave movement are theories, or attempts to model that kind of thing. We know that we can stop aging by traveling at the speed of light. When an object travels with the speed of light, that thing causes a situation where that particle gets so much more energy than it loses. And that is the situation where the particle is not aging. 

The speed of light is relative. When the universe expands the quantum fields that are slowing the time will turn weaker. And that means the material is also turned thinner. So in the young universe speed of light is slower than it's now. 

That thing that should be real is the medium, where light travels. Affect the speed of light. The speed of light is lower in water than in the air and in air, particle travels slower than in a vacuum. 

But the thing that makes the speed of light relative is that we can observe it outside from water. If we would live in a universe filled with water, we would not see that difference. The speed of light is always the top speed. But the differences in the speed of light in the medium are possible to see only when a photon or some other particle crosses the border of those mediums. 

Cherenkov's radiation forms when a particle crosses the speed of light when a particle crosses the border between water and air, in a short moment,  it travels faster than the speed of light. Things like neutrino detectors benefit that idea. When the particle's speed decreases, it sends a blue light shockwave. And that blue light shockwave turns the sky to blue. 

Because it must release kinetic energy to water for slowing its speed from the top speed in air to the top (or highest) possible speed in the water. But we can see that thing only because we can observe the border between air and water. 

That's why we cannot measure the speed of light outside our universe. The reason for that is we are inside the system. We know it's higher. But that's the only thing that we know. 

Aging means that particle turns to wave movement. And that means time is real in the material. The reason for that is the expansion of the universe. And then we are facing the question is time travel possible? As I always said, like Einstein and Hawking said, time travel forward in time is possible by accelerating the particle or object to so close to the speed of light as possible. But then again we can virtually cross the speed of light. 

The idea for that virtual crossing the cosmic speed limit is this: (Escaping velocity + the speed of object should be over the speed of light). That thing should make particle younger because it gets more energy. And that energy should replace the energy that the particle lost in quantum vaporization. 

But is time travel backward in time possible? The fact is that requires that time exists in space. And nobody has seen time in that form. The thing is that time is unknown to us. It's the thing that we can see from the clock. But that time is not the time that physicists are calling time.

Neutron lasers and neutrino beams are the next-generation tools.

Neutron lasers are neutron clouds that are trapped in magnetic tanks. And the main problem with that system is how to get neutrons. The powerful magnetic field can trap neutrons from nuclear reactors. Neutrons are polar particles so the magnetic system can pull them backward slowing their speed. And then the magnetic field can lock neutrons in a magnetic chamber or tank. 

Those systems have based on the idea that when neutrons are stressed with the energy they send neutron radiation. Those neutrons will capture from nuclear reactors. Then in the middle of the tank is the group of neutrons that are put in line. Then the energy will pump to those hovering neutrons. The neutron cloud that surrounds those entangled neutrons will pump energy to them. And they send neutron radiation in both directions.

Below: A diagram of the neutron laser.

The diagram of the neutron laser is 

1) Neutron cloud

2) Linear positioned neutrons 

3) Outcoming energy 

The outcoming energy stress neutron cloud surrounds linear neutrons. And the beam is forming in that part of the system. Maybe a magnetic field can use to trap those neutrons in the laser system. If that is possible. The neutron laser can be a reality. And neutron-lasers can use as a model for neutrino lasers. 

Image 2) The system used to create the most powerful neutrino beam. " The design of the experiment is elegant — produce neutrinos and measure them at Fermilab, send them straight through 1,300 kilometers of earth, then measure them again in giant liquid-argon detectors at Sanford Lab. Credit: Fermilab". (Phys.org/How do you make the world's most powerful neutrino beam?) In image 2 you can see how difficult is to create a neutrino beam. And that means capturing those particles is even more difficult. 

Neutrino beam can use to research protons.

New sensors in Fermilab were used to test the ability to create a neutrino-particle beam. If that particle beam or "neutrino-ion cannon" is possible to create. That thing allows observing things like the proton's internal structures. The name of that test system is MINERvA. And it's the beginning of the next-generation detectors that can scan subatomic particles' internal structure. 

Neutrinos are ghost particles with very weak interaction. That means they can travel through entire planets without touching anything. And that makes it very hard to detect them. Because neutrinos are particles, they can use to send similar radiation to neutrons. But neutrino radiation is a very short wave. There is a possibility that some kind of magnetic field can trap neutrinos in the chamber. And then powerful radiation will aim at that neutrino cloud. 

When radiation stimulation ends. Neutrinos are sent similar radiation with neutrons. Neutrino beams can use to detect the internal structures of protons. Or they can use "super X-ray" systems that can see many things that are impossible to see another way. Another version is to use neutrinos like ion cannons use ions. But the problem is that neutrinos are not following magnetic fields with very high accuracy. 

Capturing neutrinos in a chamber is not a very easy mission. But if that is possible. It can create a new type of instrument that can observe the internal structures of protons.

New studies are uncovering the form of PTSD.

PTSD (Post-Traumatic Stress Disorder) is one of the most interesting things in psychology. PTSD  forms from traumatic stress, like when people face ultimate violence. PTSD is connected with war. And that means the case, where people do not remember anything about the combat situations. 

But also, accidents and other types of violence like street violence can cause PTSD. PTSD is the result of ultimate shock. And the thing that uncovers PTSD are flashbacks and sometimes phobias. PTSD is linked with all kinds of violence. Verbal violence like threatening children with rejection can cause PTSD. 

There is the possibility that if the person is a child and faces stressful situations like almost being hit by a car that child doesn't dare to tell about that thing at home. Especially if that child is at that place without permission. 

Same way, if the child is the eyewitness of a violent situation, that thing causes traumatic stress. Even the threat can cause the situation. That person doesn't dare to climb on roofs. And sometimes things like threats in some summer jobs are uncovered because a person is afraid to do that kind of work. 

When the person will go to a similar- or same-looking environment where a traumatic situation happened. That thing causes flashbacks. And some "ghost experiences" are flashbacks caused by PTSD. If the person faces a situation at a very young age where the car almost hit that person a similar place can cause a flashback. And the person sees a similar car coming towards them. 

Stressful situations like sexual-, or some other kinds of harassment in cellars can cause the situation. That person will not dare to go cellar even in when that person is an adult. Researchers are investigating PTSD because it uncovers hidden violence.

The new artificial plume robot can act as the ultimate observation tool.

The new light-driven robot looks like a plume. Its controllers control that machine by using light. The robot itself looks like a plume. That makes it very interesting. The artificial plume can land on the human body and observe things like neural electric signals. That new nano- or miniature robot can operate along with quadcopters that are transmitting signals to it. 

The light gives power to that robot, but the same light can use to give commands to that robot's tiny computers. And that means they can slip into houses and other things. Those tiny robots can interact with larger quadcopters. And they can be the ultimate couple in the recon missions. 

Miniature robots are always very interesting tools. And there are many problems with those systems. But those systems have a big opportunity in observation, recon, and all kinds of things. 

The first one is how to make microchips that are agile enough. Those miniature robots can collect samples from liquids like oils. They can check if the person is alive. And they can also operate as recon and intelligence missions. If those systems have seismic sensors they can listen to the surface oscillation and send that data to the headquarters which can be on another side of the Earth. 

The large group of miniature robots can also use to fix holes in the ship's hull or even in flying aircraft. The miniature robots will cover the hole and act as the support structure for repairing compression. And that kind of thing can make many things safer in the future. The field of miniature robots is unlimited. The imagination limits the use of those systems. 

They can observe chemicals or animals in nature. The miniature robots can make recon and intelligence missions. They can place themselves in the clothes and slip into the targeted building.  Those robots can slip into the computers and then send all data from those systems to their operators. The miniature robots can also use to give things like botulinum injections to targeted people. And that kinds of things are making them extremely dangerous. 

Miniaturized robots are the next-generation tools for many things like sensing air pollution, and searching for fire in buildings. Observe rooms and tack unauthorized people. Or they can simply observe air quality in tomorrow's buildings.

NASAs new DRACO engine takes a human to Mars in days.

"Artist concept of Demonstration for Rocket to Agile Cislunar Operations (DRACO) spacecraft, which will demonstrate a nuclear thermal rocket engine. Nuclear thermal propulsion technology could be used for future NASA crewed missions to Mars. (DARPA)" (Breaking Defense/NASA funding DRACO nuclear thermal rocket engine under deal with DARPA)

DRACO (Demonstration Rocket for Agile Cislunar Operations) is one of the most interesting nuclear thermal rocket engines in the history of that kind of research project. The DRACO engine heats hydrogen to 5000 degrees Fahrenheit or 2570 degrees Celsius. 

And the benefit of that kinds of systems is that their thrust is greater than electric propulsion. Nuclear thermal propulsion is like all other rocket engines. But it uses a nuclear reactor for expanding propellant. 

That allows many types of operations. When we think about the power of nuclear thermal propulsion it's one of the most promising engine systems in interplanetary missions. If the propellant like hydrogen comes to the engine from the upward or front side. 

It gives a very powerful punch to the front of the reactor chamber. And that kinds of systems are making it possible to transfer people to Mars in a short time which means a couple of days.

Also, nuclear thermal propulsion is a powerful tool for probes that should take samples to form Jupiter's and Saturn's moons. The thing is that the nuclear thermal propulsion system is not very sharp with the propellant. So the Jupiter or Saturn shuttle can fill its propellant tank from the hydrocarbon oceans or the giant planet's atmosphere. The only thing that limits the type of propellant is that it must travel through the turbine pump. 

The military can have many useful ideas for the DRACO system. 

The nuclear thermal engine can have many purposes. And that's why also DARPA is a participant in that project. The DRACO engine makes it possible to create the most powerful military systems ever created. In some visions, nuclear weapons would park to orbit other planets. 

And if those "super bombardment systems" are needed. The command center would give orders. And then the nuclear-powered device can aim at Earth. The speed that nuclear thermal propulsion can give to the system is enormous. 

The kinetic energy concrete-filled shell that is removed from the nuclear-powered carrier can hit the target with enormous power. In that model, the nuclear carrier continues its journey past Earth. When it released that "artificial meteorite". 

Or the system can also use a thermonuclear warhead. That is one of the most frightening visions that nuclear thermal systems can make. Researchers took the idea for that thing from "Project Orion".

Nuclear rockets are the most effective tools for civil and military operators.

"Illustration of a Mars transit habitat and nuclear propulsion system that could one day take astronauts to Mars. Credit: NASA" ScitechDaily.com/Could a Nuclear Thermal Rocket Engine Power a Trip to Mars? NASA and DARPA Are Testing)

Nuclear thermal propulsion is a powerful system. It allows the possibility transfer spacecraft to Mars in a short time. If we compare that system with regular chemical rockets. Nuclear thermal propulsion is one of the most promising systems in the world for many other missions than just for the interplanetary drive. 

The nuclear-powered systems can use to make repairments service to space telescopes. That is orbiting the sun far away from Earth. Also, nuclear-powered space shuttles can operate freely in the orbiting trajectory. 

The nuclear-powered recon satellites or recon shuttles can wait at high orbiters. And then they can dive into the lower orbiter for their missions. And then return to a higher orbiter. 

Small-size nuclear reactors can use subcritical - or modified thorium reactors. In that system, an outcoming energy ray like a laser- or microwave radiation keeps fission going. 

Modular nuclear-powered systems can mount in the small suttle's cargo bay. Those miniature reactors can use the plutonium with weapon enrichment level or modified thorium technology. 

Modified thorium technology or subcritical nuclear reactors are safer than regular reactors. Subcritical nuclear reactors require laser or outcoming energy rays to maintain fission. Cutting energy rays ends the fission reaction. 

Nuclear reactors can use for powerful spaceborne lasers. 

Nuclear reactors can also use in spaceborne military satellites. If large-size satellites are far away from Earth that gives them time to react to incoming ASAT weapons. There is a possibility that four large-size recon satellites can see almost the entire Earth if they are at stationary trajectories. Those satellites are in a static position and they would turn their telescopes. And that allows that system to see all positions on Earth in seconds. Those satellites might be similar to the JWST telescope. 

But stationary recon satellites are good targets for ASAT weapons. That means they need the weapon system to defend themselves against kinetic energy ASAT. And those systems can use also be against other satellites. The same satellite can operate as recon and attack missions at least against other satellites. 

If the killer satellite is above all other satellites it can destroy targets by using high-power lasers or maser rays. The military killer satellite can al jam the communication of other satellites. And those systems can deny communication between nuclear submarines and command centers.

Is it possible to use asteroids as spacecraft?

The image above this text is David Hardy's vision of asteroid-looking spacecraft. The spacecraft has ion engines for maneuvers. In Hardy's vision is a possibility. The craft could be equipped with antimatter or powerful laser systems. That means it could defend itself against incoming asteroids. But that system could also bombard planets by using antimatter ions. 

The fictional asteroid craft was created by equipping the asteroid with systems like ion engines and other things like self-defense lasers. And maybe that kind of system is possible in the future. 

There was once a plan to use asteroids as bombs. In those plans. The creators of those kinds of weapons didn't mean to use natural asteroids. They planned to use aerodynamically shaped concrete profiles that will shoot against ground targets from the orbital trajectory. Those ammunitions destroy targets by using kinetic energy. And that's why those weapons are called meteorite bombers. 

Using asteroids as spacecraft is not a new idea. In some futuristic theories, alien civilizations and maybe humans in the far future will use asteroid spacecraft as reconnaissance or intelligence vehicles. The idea is that the craft that looks like an asteroid would operate unseen in interesting solar systems without disturbing other intelligent species. Those space reconnaissance spacecraft could be manned or controlled by artificial intelligence. 

In this text, I want to highlight one thing. That is that the asteroid recon vehicle is not necessarily manned. It might be a probe that is searching for intelligent lifeforms. When the asteroid Omuamua arrived in our solar system, that caused discussions about the possibility that it was an alien reconnaissance vehicle. The fact is this: nobody landed on Oumuamua. And that means we don't know if that thing is some probe or not so that thing is officially open. 

By the way...

Could the "Flying Dutchman" mean some UFO? 

Regularly people think that "Flying Dutchman" is fata morgana. If the light comes at a certain angle it will make the ship's shape in the air or rain. In some other theories, a tiny wormhole or Enstein-Rose bridge acts like a light cable and brings light from the past to modern times. 

Sometimes is introduced a theory famous "Flying Dutchman" is the alien recon vehicle. That theory is not mentioned, at least very often. And nobody ever visited the flying dutchman's deck. The thing is that the world is full of mysteries. And we should keep our minds open. So this is the reason why I wrote that the "Flying Dutchman" can be UFO.

 Nuclear reactors and ion engines could give a powerful propulsion system to the vehicle that masked to sail. The sails would be the heat exchangers for the nuclear reactor. The system could fly by using vertically and horizontally aimed ion engines. That vehicle could fly for years if it uses nuclear power.
