Can we find aliens someday in the future?

  


In philosophy, the creature or object does not exist until we mention it. The existence is not black and white. It's like the grey spectrum under the drawing program.  The white is the position where we do not even mention the object. Then the scale goes to black through the levels of grey. Those levels are that we mention the object, discuss it, and then take images or other documents about it. And then the black is the fully proven evidence of the thing. The knowledge or even hypothesis makes the object exist. 

So do alien civilizations exist or not? That is one of the greatest mysteries in the universe. Alien civilizations do not exist until we find evidence about their existence. But if we don't see alien civilizations or keep in contact with them daily, that doesn't make them non-existent. Civilization is real if it exists. And then it can exist 10,000 ly away from us. 

That means we ever can make contact with them. Or do we? We all wait for the day when hypothetical other civilization makes contact. At the same time, we are afraid that day can come after 10,000 years, or it can come tomorrow. Or maybe we are the aliens that meet some primitive civilizations someday in the distant future. 

We are alone until the alien takes contact, or we can isolate the alien message from the cosmic radio background.  The day when aliens make contact makes them real. But until we see those signs. Aliens are only hypothetical creatures. The alien civilization is a totally, unknown thing to us. And that means the aliens are a mystery until we see them. 

Why aliens don't answer? Maybe they don't get our messages yet. Maybe they don't want to answer. And maybe those aliens want to be sure, that their answer does not cause war on the worlds. Or maybe they don't want to discuss with the unknown. Because. They might be afraid that the hostile civilization gets their message. Same way as humans aliens must be sure that the message is sent by a friendly creature. And maybe they don't answer immediately. They want to research signals before they decide to make an answer or forget. 

Maybe there are no alien civilizations so close, that our signals reach them. The alien civilization might not exist so close, that we can communicate. But until we see the alien civilization those things are not real. And the contact is the thing that turns them real. And are we ready for that thing? 

But can hypothetical aliens be dangerous to us? The worst scenario is that the alien civilization answers using too high an energy level. And that can detonate the entire Earth. In some scenarios the alien civilization uses an energy level that is the same as FRB, and if they use too high energy in data transfer that thing can destroy the entire planet. 

The hypothetical alien craft that arrives at our solar system is the probe. If there are some programming errors. That probe can accidentally destroy the entire earth. Some Harvard astronomers introduced that the first alien spacecraft that came into our solar system was the probe, which lost contact with its builders. 

In some scenarios, the other civilization can send the probe to another solar system. If those probes have programming errors that can cause a situation, where the probe impacts Earth with a speed that is about 10-25% of the speed of light. 

Another dangerous thing is if somebody finds that probe's fuel tanks, which are full of antimatter, that thing causes large-scale destructions. In the worst scenarios, there is a black hole in those tanks, and some person can accidentally release that thing into our atmosphere or orbiter. In that scenario, the probe or its tanks could seen as an incoming missile or asteroid, and then the defense system starts to fire. And that can release the power source of that thing to space. 

Many things can go wrong in interstellar flight. Even if the alien craft cannot travel faster than the speed of light, maybe aliens can use things like a Tipler cylinder that allows those, still very hypothetical creatures to travel between stars. The time dilation in that time machine denies the aging of the crew. Or maybe advanced biotechnology makes those creatures immortal. 

Those things are not possible for humans. But maybe aliens have different cultures. Maybe aliens do have not the same relationship to their home planet as humans have. Maybe aliens are created using cloning technology. Or maybe, they are robots that living neural tissue controls. The thing is this. Until we see aliens all roads are open.

Researchers created fully functioning mini brains using bioprinters.

  "Currently, the global annual cost of treating brain diseases amounts to €3 trillion. (Image: Mostphotos)" (University of Helsinki, Development of human-derived mini-brain close to completion - A new technical solution promotes the treatment of brain diseases) When we think that AI cannot reach the same intelligence level as humans, we talk about binary-computer system-based AI. That AI is a very passive thing. But biological microchips where living neurons communicate with microprocessors are different things. Those systems are in mini-brains. Or cloned neurons that developed for medical testing. Those mini brains involve living neurons that interact similarly, to neurons in the human body.  "Scientists at the University of Wisconsin–Madison (UWM) say they have created the first 3D-printed brain organoids that function like natural brain tissue." (FreeThink, Scientists create the first “functional” 3D-printed mini brains) “The neurons communicate, send signals, i

Researchers found a "pause" button that can stop the human embryo advance.

Researchers found a "pause" button that can stop the human embryo advance. And that thing can have many solutions. In the case of a mother's illness or injury, the medical team can save the embryo's life by stopping its advance. But that ability can make things like interstellar travel possible.  It's one theoretically, a very easy, way to transfer people to the other solar system if we don't want to get them back. The mission controllers can use the human embryos for the other solar system. Those colonists can have the robot controllers, and they can have the training material for the mission. That thing might not yet be possible. Because of our culture and moralistic-ethical thinking. Of course, technology sets limits to that kind of project.  "Research indicates that humans might harness a dormant diapause-like capability to optimize reproductive health and IVF success.

Wormholes and fundamental avionics.

Image
Thoughts about wormholes and hypothetical engines.  Acoustic and electromagnetic systems can create acoustic or electromagnetic channels through air or water. The system can create an acoustic beam or laser beam, that pushes air molecules out of the aircraft's way. That makes the air thinner. And that allows the aircraft to move faster than usual.  An interesting way to raise objects silently up from the ground is to use the tornado that formed above the craft. There is a hatch under the craft and then the system creates an artificial tornado above the craft. Then the craft closes the hatch, and the tornado above the craft pulls it up. The system requires a hatch that can feed rising tornado using air.  The hatch allows it to rise that tornado high enough, that it can pull objects up. The hatch can also used for the acoustic tractor beam. The acoustic tractor beam is the tornado that pulls objects up from the ground. The horizontal tornado makes the craft move faster or it removes
