Challenging Einstein.

"Research into gravitational lensing, where light bends around massive objects, aligns with Einstein’s predictions from billions of years ago. However, newer findings suggest some deviations, indicating potential variations in gravitational behavior over large distances, sparking further investigation into the validity of Einstein’s theories.

The Theory of Relativity means that everything is relative to something else. Einstein's paradox, called the "Train paradox" is that an object can move very fast even if it's not moving at all. When we stand in a train that moves 200 km/h we can say that we don't move at all. But if somebody stands outside the train, that person can say, that we travel 200 km/h. In that case the space moves. 

So the movement is energy. When we stand or sit in a moving train that means we don't use energy. The moving train, if it's an electric train, takes electricity from wires. And then it transforms it into kinetic energy. When the train slows its speed it transforms its kinetic energy into thermal energy. 

During that process, the energy transformation pulls kinetic energy out of the passengers. But if we jump out from the moving train the kinetic energy that train stored in us would remain in our body until we touch the ground. The paradox is that what if we stand in spacecraft that travel speed of light? And then start to run forward? We can say that the quantum fields and wave movement that we face are like air molecules. We would not interact with those waves and fields if we were in a closed space. 

The thing is that. It's possible. That nothing happens. Because we are in a closed space. But if the nose of the spacecraft opens or we would sit on an open spacecraft and step forward that causes a situation in the impacting energy field that impacts us faster than the speed of light. In that case, the open structure or open platform makes it possible for the field to interact with objects. 

If we think of the effect where impacting wave movement or energy field can cause a situation where the particle virtually crosses the speed of light that effect could make it possible to escape from the black hole. The idea is that the impact speed between quantum fields that travel against a particle's trajectory can cross the speed of light. That effect can form a wave or particle that can escape from the black hole. But that requires that the particle can change its movement direction in the event horizon. 

" Artist impression of ESA's Gaia satellite observing the Milky Way. The background image of the sky is compiled from data from more than 1.8 billion stars. It shows the total brightness and colour of stars observed by Gaia released as part of Gaia’s Early Data Release 3 (Gaia EDR3) in December 2020." (ScitechDaily, Gaia (spacecraft))

The most modern instruments like the Gaia satellite, bring data that has been impossible before this time. Those observations tell us that things like gravity have not been stable in the history of the Universe. The strength of gravity- or gravitational effect- has changed in the universe's history. And that means that Einstein might make mistakes. 

Or maybe there is a distance where we can use Einstein's Theories of Relativity for modeling spacetime. The fact is that things like Newtonian gravity models are still useful tools for calculating gravity and object interactions. 

Same way. Things like Theories of Special Relativity and General Relativity are suitable models for calculating an object's behavior in the different types of gravity fields. The distance between objects from gravity centers determines which theory or equation is most suitable. But those theories are never tested in extremely long distances and in borders like when a particle crosses the line between the "regular universe" and cosmic voids.

The Big Bang was an event that released all known energy and material to the spacetime.  That model means that the Big Bang also released gravity into the spacetime. So when black holes "eat" material and wave movement they should eat gravity as well they eat other wave movements like visible light and radio waves. 

Gravity or gravitation is wave movement as well as electromagnetic radiation. That means there must be some kind of scattering effect between gravitational waves. In the young universe, the energy level was higher than in the modern universe. The Higgs field or base energy field in the universe was also stronger. 

Gravity waves were stronger in dense fields. But gravity waves impact each other. That caused the thing that gravity waves to scatter stronger than in the modern universe. The impacting gravity waves simply shared each other in the smaller pieces. And maybe that happens also today. But in the young universe, those gravity waves were wider than they are today. 

In black holes, massive gravity stretches all objects. That means. Also, gravity waves can travel straight. The massive gravity that pulls objects in the pothole minimizes entropy. And if the wave movement and particles turn into spaghetti-shaped things that are straight there is no entropy at all. In some models, the gravity waves can touch each other inside the black hole. That forms a gravitational electric arc that could create so high energy gravity waves that they can push the event horizon back to space. 

If we think this way the massive gravity fields should also focus gravity waves as they focus other wave movements. That means gravity lenses should also affect gravity waves and focus them into one point. And if that thing is true black holes should also pull gravity waves inside them. Or if a gravity wave is wave in the Higgs field that means black holes pull the Higgs field inside them. 

Same way. When the universe expands there should be less gravity left in the space that turns larger in comparison to energy and material. That thing doesn't mean that there gravitational interaction between particles and objects turns weaker. But is the thing that causes the effect the distance or does black holes pull that gravity inside them? That means cosmic inflation affects also gravity.

Why we afraid artificial intelligence and new killer-drones?

This is a writing about the paradoxes of war and militarism. The militarism and war are things, what is strictly out from normal people head, and there are many things, why is not very tolerated to speak about the military systems. One of them is that the national security is limiting the comments about those things. And when we are looking very sharply to the militarism and army, we are seeing that our religion has been against violence in 2000 years, and we still fight together by using weapons.


And even if we are against violence, many people are getting their salary from military forces their equipment, and the weapons industry around them. War is good business for the weapon dealers, who offers more and more lethal and advanced weapons, what suits for many missions. Also, support equipment like GPS systems is a very good article, because the owner of those satellites can cut the location signals of those weapons, and that's why they cannot use against the deliverer of GPS-system, and that ties the clients more effectively to the influence of another actor in the field of international politics and strategies. Strategies have always depended on the politics, and that's why the political support for weapon trade is extremely important.

We must say that using killer-drones would create the military, where doesn't serve a single man. But here we must know, that if there would be autonomous killer robots, what replaces the places of the military personnel, we would come to the situation, that there would be no work for the men, who serve in those military forces. And one of the first group. what would be lost their jobs, are the fighter pilots, who serve in the war against terrorism. Those missions can be done by using drones, what just fly to the target, and then drop their weapons.


The human's advantage in comparing with robots is that human would make surprising movements for those aircraft. And that's why human pilots still win the drones, and this is the thing, what keeps those pilots in the cockpits. When we are thinking that the use of missiles and drones is somehow cowardly action, we must say, that the leaders of the terrorist organizations and military forces would not be in any danger in those operations. If some Tornado or Sukhoi-pilot would drop the bombs from the high altitude like 10 000 meters, there would not have the single missile, what could harm that aircraft, if the opponent is some kind of Isis-terrorist.


The smart bombs, what have satellite guidance are extremely sharp, and in those operations, they could destroy targets very effectively.  The civilians are not suitable to comment those things, because that would be harmful to the reputation of military forces. If those pilots would be replaced with the artificial intelligence, there would not be heroes in another side, what is, of course, our side. But when we are going to speak about the fighters, we could act like some children at the sandbox, who are asking each other, whose car is the best?


In this case, when we are talking about multipurpose-fighter contracts, we can ask the question, what is the best, 4th,5th or 6th. generation fighter or multirole aircraft? And in this case, people have the right to talk, which one is the best, Super-Hornet, Gripen or SU-27? And if the writings have no influence or expertise, why those people would not have right to write about those things? Of course, somebody says, that I'm writing this for revenge because I didn't have promotion in the 100th. anniversary of the  Finnish defense forces, and that's why I' writing about this thing.  But people have right to their opinions.
