Can alien civilizations find us?

When we think that alien civilizations see our microwaves and other signals, there is a possibility that they see us. But making contact with other civilizations is a complicated thing. The aliens have similar problems with us as we have with hypothetical alien civilizations. If aliens want to see what our messages, like TV data, involve, they must break our codes the same way we should break their codes.

We are aliens for aliens. That means their numerical systems might be different than ours. And they must also detect our signals and recognize them as the products of intelligent creatures.

But if aliens sent some kind of voyager to detect intelligent lifeforms from other stars, they might send robots for the first journey. If hypothetical space colonists are traveling to another solar system, Those aliens might send the robots to make the base before the human colonists.

The purpose of those robots is to make comfortable and good bases for colonists. Sometimes there is the idea that even before Mars astronauts arrive, large groups of robots are making the base ready for those human astronauts. In that model, the base is ready to offer protection and a workplace, like laboratories for astronauts who work on Mars.

"Researchers from Mauritius and Manchester University used crowd-sourced data to simulate radio leakage from Earth’s mobile towers to predict what an alien civilization might perceive from afar. The team found that while individual systems output low radio power, the combined spectrum of billions of devices, coupled with more powerful future broadband systems, could be substantial enough to be detected by advanced extraterrestrial civilizations".

Are "little gray men" some kind of robot?'

At first, I must say that there is a possibility that those mysterious "little gray men" could be robots that somebody uses in some kind of ultra-secretive mission. Or the owner of those robots has not been reported or has somehow introduced themselves.

The fact is that those gray aliens could be very advanced robots that use new types of artificial muscles. Making artificial muscles is not as difficult as people think. Silicone bags have a shell equipped with nano springs that can act as artificial muscles. When electricity is injected into both sides of the cell, the electricity pulls up those nano springs.

There is also the possibility that biological muscle cells can turn into artificial muscles. In that case, the organelles of those cells must only be removed, and there must be embedded nanotechnical microchips. Or if the creators of that thing want, the only thing needed is to connect the two heads of the facial muscle cell with electric wires. And then those nano springs or natural proteins pull up the silicone bag.

There is also the possibility of using long proteins as artificial muscle cells. In that case, those fibers are connected with some kind of miniature, nano-sized mangle that pulls those fibers through it. And then those fibers pull up the artificial muscles. Those artificial muscles make it possible to create more human-like robots than ever before.

Well, is the Universe 26,7 or 13,6 billion years old?

The age of the universe is hard to detect. We can see the last flash of the Big Bang. And we can see the moment when radiation started to form material. But we cannot see the Big Bang itself. Many things remain unknown. The normal model of the Big Bang was that the effect, or "the bang," was stable. That means the Big Bang released material and energy into the universe. Or the Big Bang released energy that turned into material in space. When we observe the Big Bang using cosmological models, we are observing it from outside. 

We cannot see time dilation or energy relationships, and actually, we don't know if the Big Bang happened at the same speed all the time. There is a possibility that there were changes in the speed at which the Big Bang released energy. And if we think that we cannot see the entire Big Bang and only the last flash of that, we are not sure how long the Big Bang remained. Or how long it released energy until the first particles were formed. So we might think that the moment when the quark-gluon plasma formed was the moment when the universe formed. That point is 13.8 billion years in the past. But there is a possibility that electromagnetic radiation existed a long time before that.

When scientists calculate the age of the universe, there is always some kind of error. The problem is that things like time dilation in a young universe make it possible for the universe to look older than it is. But the problem is that the universe was different in its youth. Time dilation, energy level, and form of material were different. So we are not sure which age is right.

When we are looking at an image of the universe, we might see that galaxies are on a layer that looks like a ball. The reason we don't know the geometric shape of the universe is that we don't know how much dark matter there is. Another interesting thing is that there is some kind of effect that makes whirls in that layer, where almost all galaxies are.

There is a supermassive black hole, and then that thing makes a galaxy around it. There is a small possibility that the shockwave that left the Big Bang impacted some other wave movements. But that requires the existence of another universe. Or there is some kind of energy peak that is making those whirls.

In some models, dark matter is released into the universe in some other event than the Big Bang. The hypothetical effect that released dark matter is called the "Dark Big Bang.". 

The standard cosmological model is that the Big Bang released all particles. But the fact is that nobody is sure about that thing. Dark matter, along with dark energy, can exist before the visible material. And nobody is sure if dark matter and dark energy have any kind of connection with each other. But when we are trying to determine the age of the universe, we must realize that we must find the point where we begin our calculation.

The point could be the point where the high-energy universe started to take on the form in which we know it. That point would be the point where the first gluons or quarks formed. The idea is that particles form from the inside to the outside of atoms.

And in that model, the gluon would be the first particle of visible matter. The problem with all models is that we don't know the conditions in the young universe. We know that time dilation was stronger. The energy level was higher, and then the first plasma formed. The energy turned into gluons and quarks. The difference between quark-gluon plasma at CERN and in a young universe is that in a young universe, the quark-gluon plasma stands alone. There were no outside effects in that universe.

But quark-gluon plasma requires that there be quarks and gluons. Time dilation is a problematic thing in the calculations of the age of the universe. Time moves faster in our universe. The dark energy effect is stronger now than in an extremely young universe. In the universe, where there were no particles and impacting waves formed the first particles, there was no gravitation. Or gravitation was different than our universe. If there were WIMPs before the first visible matter particles, there was some kind of gravitational effect from WIMPs.

There is a possibility that there was no internal gravitational interaction before the first particles formed. There was something that created things like black holes in the young universe because wave movement formed material in the Schwinger effect that required the ability to change its direction. There must be something that made waves cross each other.

Anti-aging medicines: the next-generation tools for continuing a working career

The thing that causes aging is damage to the DNA. There is a self-destruction process in cells. But somehow, that self-destruction doesn't always work as it should. If that self-destruction doesn't work, the result is that zombie cells are left in the body. Sometimes the thing that causes failure in the cell's self-destruction process is in genomes where telomers are turned short. Telomers are the first and last parts of DNA. And the self-destruction mode of the cells is hidden in those telomers. So if the self-destruction can connect back to the zombie cell's DNA, that destroys those harmful cells.

Another way to clean those harmful zombie cells away is to use their shell antigens. Some of the zombie cells are not similar to regular cells. The zombie cell is hairy, and that means some mark proteins will touch those cells better than wealthy and functioning cells. Those proteins can mark the cell so that the immune system destroys it. Zombie cells play a key role in cancer cases. Those cells are turning into cancer cells.

A zombie cell means that the cell's mission is over. But they don't "want to die". That means the nanotechnical medicines can contain some kind of chemical mark or antigen that touches only those zombie cells. And that helps the immune system destroy them.

Artificial intelligence is the ultimate tool for the R&D process in medicine. The term anti-aging medicine means medicines that remove zombie cells from the body. Or maybe in the future, those medicines can fix damaged DNA. The difference between those medicines and some cosmetic products is that those medicines affect something that causes aging. And the most conventional way is to just mark zombie cells for immune defense so that it can remove cells that have completed their mission from the body.

"Researchers have utilized AI to discover new senolytic compounds that can suppress age-related processes, such as cancer and inflammation. By training deep neural networks on experimental data, they were able to identify three potent drug candidates from a chemical pool of over 800,000 molecules, promising superior clinical properties to existing senolytics." (ScitechDaily.com/Artificial Intelligence Unlocks New Possibilities in Anti-Aging Medicine)

Zmbie cell

The problem with zombie-cell markers is that they can mark the wrong cells. And that thing can cause catastrophic situations.

Genetic therapy, where damaged DNA will be replaced by fresh DNA, can be the answer to an extremely long life. But the requirement for that therapy is that there be fresh DNA that the system can use to replace the DNA from the cells. The problem is that the DNA must be taken at a very young age. The PCR Polymerase Chain Reaction can multiply that DNA.

But AI-controlled nanotechnology can also make the DNA copy by using a digital database. The DNA is in digital mode, and then nanorobots are making that DNA by using similar systems that are used in protein and complex chemical manufacturing. Those systems are in use in medical factories. Nanotechnology and AI can also make it possible to create artificial DNA. That thing requires complete knowledge of the functions of every DNA base pair. But AI and CRISPR can make this kind of thing possible sooner than we ever imagined.

The problem with anti-aging medicines is that they should fix genomes or DNA. The system can replace damaged DNA by using fresh DNA. There is a possibility that the DNA that was injected into the cells contains a sequence that makes those infected cells immune against some cytostatic or virus, and that helps to remove non-infected cells from the body. Here I mean that the cells' genome is not changed and will be easier to remove.

But making a person young again is a more complicated process than just removing zombie cells from the human body. The system must remove damaged DNA and then inject new DNA into those cells. The problem is that there is a lot of DNA that is needed. The thing that could make the process where the DNA is changed in the cell's nucleus possible could be genetically engineered immune cells, like macrophages or B lymphocytes. Those manipulated immune cells can be injected into a human's bone marrow, and then they can produce artificial viruses. Or change the DNA in the cells.

Advanced nanotechnology also makes it possible to engineer the DNA of bacteria or any other cell. That genetically engineered immune cell can produce DNA that it can use to make artificial viruses. Genetically engineered macrophages can change the DNA in the cell's nucleus. If we want to make people young again, we should replace damaged DNA with fresh DNA. There is a possibility that the DNA that replaces the old DNA involves a sequence that makes "infected cells" immune to some medicine or viruses. Then the cells that are not infected will be destroyed.

The dark energy and antigravitation

Graviton and antigravitation: is dark energy antigravitation?

Mass and gravitation have a connection. Mass is the thing that determines an object's gravitational force. And Higgs field should give mass to objects. So Higgs field could be the thing that connects WIMPs, hypothetical dark-matter particles, gravitation, and visible material. The thing that supports this model is that dividing particles from Higgs boson includes W and Z bosons. And the interaction between Dark matter and WIMPs should contain weak interaction or weak force. So that means the WIMP might interact as well with gravitation. But also with Higgs field. 

Gravitation is a mystery, but gravitational waves, which are the newest tool in physics, are uncovering the mystery of that most dominant force in the universe. In this text, the graviton is the particle that forms and transmits gravitation. So if the vaporization of that particle forms gravitation, the antigravitation would be the quantum radiation, or "vapor", from that object. Or it can be emission radiation that the graviton sends when gravitational radiation stresses it.

The source of gravitational waves is a very small particle. And if we think that gravitation is radiation, its wavelength is very short. So if a graviton is a particle that is between gluon and quark and it sends gravitational radiation, the antigravitation would be the emission radiation from those particles.

So could gravity be the same thing as the Higgs boson? The Higgs boson is the thing that gives mass to particles. And there is the possibility that the Higgs boson is at least very close to the mythic graviton. We see the Higgs boson when it is shot out of matter, and we see that particle only when it flashes just before energy travels out from it.

So if the particle that is between quark and gluon or inside all elementary particles is the reason for gravitation, that thing happens like this: When those particles are vaporizing or turning into electromagnetic waves, they form an electromagnetic low-pressure around them. That low electromagnetic pressure pulls particles toward each other. When that particle between them vaporizes, it turns smaller and compresses an entire atom or some other object. That thing causes the electromagnetic low pressure that we see as gravitation.

That explains why neutron stars, hypothetical quark stars, and black holes have such strong gravity fields. In those objects, the material is in homogenous form, and all particles, like gravitons, have the same size. So they vaporize simultaneously. In that model, all particles that are forming gravitation are vaporizing at the same time.

Sometimes researchers introduce the idea that dark energy is antigravitation. If we think that vaporizing the Higgs boson or some other yet unknown particle that vaporizes between gluon and quark is the thing that is behind the gravitational effect. We must say that proving that thing is extremely difficult. The particle that is smaller than gluon sends radiation whose wavelength is so short that it's hard to detect.

The reason why small particles send radiation or wave movement with such a short wavelength is that they send it more often than large particles. Small particles transmit energy more often than large particles because there is no room for extra energy. When radiation with a short wavelength impacts other particles, it causes smaller changes in the energy level of that larger particle than radiation with a long wavelength.

Emission radiation is wave movement that comes out of a particle when it releases its extra energy. And the thing that destroys material is the end of the stressing radiation. At that moment, the particle sends its extra energy out. The source of gravitation is something very small. And gravitation is very short-wave radiation. So if we think that the mass of particles and objects forms when some particles between gluons and quarks are vaporizing, the energy that this hypothetical particle sends is antigravity.

The fact is that gravitation, or gravity, is the force that has a long-range effect. And another thing is that. Gravitation is the force that affects large material masses or large groups of particles. The third thing is that gravitation doesn't transfer energy to particles. That means gravitation is a so-called "cold force".

Things like quantum gravity are interesting phenomena because they are the smallest elements of gravitation, and maybe if we can see that phenomenon, we can see antigravitation. The problem is how to confirm the existence of antigravitation. Gravitation is such a weak force, or its wavelength is so short, that other forces are covering it at the subatomic level.

Einstein's gravitational model and Theory of Relativity still stand strong.

The fast shrinking of a black hole is what causes its strong gravitational field.

All black holes are losing their mass. When black hole masses decrease, they shrink. And that shrinking causes low electromagnetic or quantum pressure around that vaporizing object. Vaporization means that an object turns into an electromagnetic wave. And then other quantum fields are trying to fill that area that the shrinking black hole leaves behind it. The fast shrinking of a black hole is what causes its strong gravitational field.

A black hole, or its event horizon, is a ball-shaped gravitational lens. That thing focuses all radiation, including gravitation, in the middle of it. And if that is true, Gravitational waves are reflections from the center of the black hole. If we think that the Higgs boson is the thing that gives mass to objects, we can use that model to explain why the gravitational field of a black hole is so powerful. If the radiation that decreases the mass of the black hole is coming from vaporizing Higgs bosons, that explains the power of the black hole's gravitational field. 

When a black hole vaporizes or loses its mass, there is an electromagnetic or quantum low pressure around it. All quantum fields are trying to fill that low pressure. And that flow is what we know as gravitation. Black holes are actually ordinary objects whose gravitational field is extremely strong. And if the vaporization of the black hole or decreasing of its size forms the gravitation, that model can be applied to all other gravitational centers, like planets. The reason why the gravitational field around planets is not as strong as around black holes is that their particle sizes decrease slower than in black holes.

A black hole or its event horizon is a ball-shaped gravitational lens. That thing focuses all radiation including gravitation in the middle of it. And if that is true. Gravitational waves are reflections from the center of the black hole.

What is a black hole? We can say that the black hole is the ball-shaped lens that focuses all radiation in the middle of it. And then that thing causes reflection from the center of the black hole. If the black hole also focuses gravitational radiation or gravitational wave movement, that explains the gravitational waves that are coming out of it. In that case, the gravitational waves are reflections from the center of the black hole.

When gravitational waves fall into the black hole, they collect around the singularity. The outgoing gravitational radiation turns that wave's energy level higher and higher until energy starts to travel out from the black hole. There is a possibility that a singularity that spins extremely fast also aims gravitational waves at its poles and sends gravitational peaks, gravitational tornadoes, or "wormholes" across the universe.

*****************************************************************

"Researchers have confirmed a fundamental assumption in physics with unprecedented accuracy — that the various properties of mass, such as weight, inertia, and gravitation, are always equivalent, regardless of the specific composition of the mass involved. This reinforces the equivalence principle, essential to Einstein’s theory of relativity, and addresses a critical point of divergence between classical and quantum physics." (ScitechDaily.com/Gravity Still Holds: Einstein’s Relativity Theory Stands Strong After Quantum Challenge)

Light cone in 2D space plus a time dimension.(Wikipedia/Light Cone): Does the gravitational focus turn the gravitational waves upside down to their mirror waves?

*****************************************************************

Can the event horizon turn gravitational waves upside down? And could that effect also happen in the focus of the other gravitational lenses? The idea is that the gravitational lens acts like an optical lens. There is a focus, and if we were looking at the image through the optical lens behind the focus, we would see the image upside down.

In some models, gravitation turns the other way inside the black hole. The idea is taken from the famous "light cone". The idea is this: When gravitational waves travel across the point where the gravitational field turns so strong that escalating velocity crosses the speed of light, that thing also affects gravitational waves and the form of gravitation. So if we think that the event horizon is a focus that unites gravitational waves like a lens unites light waves, the event horizon turns the gravitational waves upside down, just like the lens makes an image that is upside down if we are looking through it behind the focus.

The quantum challenge cannot shake Einstein's Theory of Relativity and its position in the world of science. The fact is that quantum theories are not yet complete because we cannot know the essence of matter. Without knowing the entire system, it is impossible to make models of it. The quantum systems are the entirety of wave movement and particles. Each fundamental force is the wave movement. And there is a distance where each force is dominant. A strong nuclear force is a force that has effects only over a short distance. That force is the interaction between gluons and quarks.

Gravitation is the weakest of all forces. But it interacts across long distances. The strong nuclear force can also travel long distances, but the wavelength is so short and the transmitting particle of that force is so small that there is no visible strong nuclear force interaction over long distances. So if there is some kind of long, strong nuclear force's distance interaction across protons and neutrons, we cannot see that interaction because the other three fundamental forces are coming from larger particles, and those nuclear forces' wave movement forms are easier to detect.

There is a possibility that the Higgs boson is normally between gluons and quarks. Or maybe that boson is inside each particle. Nobody knows if that particle is the Higgs boson or if there is some kind of other particle called "top" or "god". When those particles are vaporizing, that thing forms electromagnetic or quantum low pressure.

And the quantum fields around atoms are pushing them lighter. The reason for that is that the size of atoms and particles decreases. In the young universe, the size of particles was larger than it is now. The reason for that is cosmic inflation. The expansion of the universe causes the quantum fields around atoms and subatomic particles to weaken. And that causes an effect where energy travels out from particles.

The JWST telescope just found the first candidates for dark stars.

The thing is that we cannot see those dark matter objects straight. But the gravitational effect of dark matter objects causes interaction with gas and dust near those objects. That interaction means that gas and dust start to whirl. And that makes the friction in those particles. The same way the dark matter object interacts with stars. And if some planet's mass dark matter glimpse impacts with a star, that causes the rise of the star's energy level. The rising temperature uncovers the dark matter particles. But there is no other interaction between dark matter and visible matter than gravitation. So the heat of those stars will not affect dark matter glimpses. 

"A team of astrophysicists has discovered three potential “dark stars” using the James Webb Space Telescope. These theoretical bodies, thought to be powered by dark matter particles, are much larger and brighter than our sun. If confirmed, they could significantly illuminate our understanding of dark matter, one of the most significant unresolved issues in physics. Furthermore, their existence could reconcile the discrepancy between the current standard cosmology model and the observation of large galaxies early in the universe". (ScitechDaily.com/Powered by Dark Matter: Webb Space Telescope Catches Glimpse of Possible First-Ever “Dark Stars”)

The JWST telescope probably found the first evidence of a dark universe. If that is true, it makes a revolution into our worldview.

If the JWST telescope's observation about stars made of dark matter is right, That thing causes a sensation in science. That observation can open the road to analyzing weakly interacting massive particles (WIMPs). The existence of dark matter stars could explain why we cannot see the mysterious "Planet X".

The answer could be that hypothetical planet X or the ninth planet, is an object formed of dark matter. So if a glimpse of dark matter causes the gravitational anomalies in planet Neptune's trajectory, that opens a new page in science and material research.

If somewhere there is an object that is formed of dark matter, that object will pull material around it. But the mass of that dark matter planet or star is too low for the black hole. The planetary mass glimpse of dark matter could be sensational.

"The James Webb Space Telescope spotted three objects that may be formed from dark matter particles annihilating one another. (Image credit: NASA/ESA)" (Space.com/Do fabled 'dark stars' actually exist? James Webb Space Telescope spots 3 candidates)

The term "dark star" means a theoretical star that is formed of dark matter. That means those stars are forming weakly interacting massive particles (WIMPs). And if those dark stars are possible, that means that there could be dark planets, dark solar systems, and dark galaxies that we cannot see. It was a long time before I wrote an article about the theoretical dark universe. In that article, I wrote about the possibility that dark matter can form similar structures as visible material.

The idea for that theorem came from observations of galaxies where there was no dark matter. Because dark matter is not homogenous around the universe, it brought up the idea that maybe there are interplanetary nebulas, but why not galaxies, planets, and even species that live in a universe that is with us? But is invisible to us? 

Maybe the finding of the Webb telescope could confirm that theorem. And now it seems that there are at least some dark stellar-type objects in the universe that are formed of dark matter. Dark matter interacts with regular matter through gravitation. So if there is some invisible object that pulls matter around it, and if the mass of that object is too low for it to be a black hole, That means there is a possibility that the object is made of dark matter.

Theoretically, dark matter is a form of WIMP. The weakly interacting particles could be particles whose spin is too high. At that point, I mean that maybe the spin of that particle is over one. Or maybe the speed of the spin of WIMPs is extremely fast. That could form the onion-looking power field around that particle. The fast spin adds two energy peaks to the rotation axle of those particles. 

Those energy peaks will just pull energy that travels to the WIMP in two directions in extremely thin energy strings. When energy travels out from particles in those energy peaks, they pull energy or a quantum field with them. And that causes quantum underpressure around WIMPs. That means that other Qauntum fields are trying to fill that hole. If that model is true, it explains why WIMPs interact only through gravitation.

New research doubles the universe's age. And thoughts about the infinite question: are we alone?

The new age for the universe is 26,7, not 13,7 billion years.

Cosmic inflation means the space expands relative to the material. The distance between particles is growing. And the electromagnetic radiation's relative to gravitation effect particles turn higher. That energy will push particles away from each other. The quantum gravitation between particles is not powerful enough. That it can resist the energy and its pushing force. 

In some models, the wavelength of the gravitation could explain that thing. If the wavelength of repelling energy is longer than the pulling energy that we call gravitation, that could explain why gravitation loses. If the wavelength of some other energy form is longer than gravitational waves that make it possible that the longer wavelength pushes particle,  like string over the shorter wavelength. 

"A new study suggests the universe might be 26.7 billion years old, almost double the widely accepted age of 13.7 billion years. The new model, incorporating Zwicky’s tired light theory and Dirac’s evolving coupling constants, could explain the existence of mature, small galaxies formed just 300 million years post-Big Bang and propose a revised interpretation of the cosmological constant." (ScitechDaily/Cosmic Paradigm Shift: New Research Doubles Universe’s Age to 26.7 Billion Years)

The effect is similar to a bigger man pushing the object with a longer stick than a smaller man pulling with a shorter stick. And that means the shorter man cannot affect to object under the longer stick. 

When the universe expands the particles vaporize or turn to electromagnetic radiation or wave movement. That wave movement makes standing waves between particles. And then when that wave movement that comes from particles impacts with those standing waves that thing forms the effect called scattering. The problem is that the scattering effect cannot explain. Why there is too much energy in the universe?

When there is silent time in science, things like alien civilizations get space in media. The fact is that SETI (Search for Extraterrestrial Intelligence) is a scientific program. The fact is that. We cannot be sure about the existence of ETI (Extraterrestrial Intelligence) until we get the first confirmed message from another solar system. 

The new tools have doubled the age of the universe. And that thing is one of the most remarkable things in cosmology. The universe's age is a very important thing when researchers want to make models of the time when planet formation begins. So researchers require the universe's age to make the model of possibility to find intelligent lifeforms. Almost all theoretical lifeforms can create machines and cultures connected to their home planet. 

"NASA’s Astrobiology Program is focusing on understanding the origins and requirements of life in the cosmos to answer the age-old question “Are we alone?” Research begins with understanding how life began on Earth, starting from the birth of our Sun". (ScitechDaily.com/Are We Alone? – Beginnings: Life on Our World and Others)

The existence of the planet is necessary for all known intelligent organisms. Of course, there are theoretical models of the things like AI-based civilization. But that kind of civilization requires the carbon-based lifeforms that put the development of AI ongoing. There is no AI without carbon-based- natural organisms with enough high intelligent levels that they can make that kind of project. 

In many models, there are lots of habitable planets. But the lifeforms on those planets are primitive. So even if we find primitive alien races like some kind of amoebas swimming in the ocean of Jupiter's Europa moon. In the case of that kind of alien organism we can say that even if we could find some kind of bacteria in those planets or moons, we still are alone. 

Those primitive aliens cannot answer our questions. So even if we can find some alien bacteria in those distant oceans, we cannot communicate with them. The model is similar as we will sit in the middle of vegetables or bacteria cultures. 

When we think about things like, really intelligent civilizations we must realize a couple of things. We are also aliens for those civilizations and same we as we are, they must be careful about contacts. If some civilization tries to make too early contacts without investigating carefully the messages, they might fall into the trap. And if some interstellar civilization wants to harm us or some other pre-Kadechev civilization, that thing requires only one about 1000 Kg spacecraft that they drive against the targeted planet. 

The thing is research on alien intelligence has just begun. Things like investigative cosmo-biology, cosmology, and SETI programs are established in the early 21st century. And in 2020's researchers started to make systematic and open investigations into UFOs. Before those programs, people tried to tell us that maybe there is some kind of intelligent civilizations in our galaxy or some other galaxies treated like clowns.
