Can alien megastructures uncover intelligent civilizations?


Image: Science Alert, Mysterious Objects in Space Could Be Giant Dyson Spheres, Scientists Say



If a civilization can use all the energy that their star sends. That makes civilization invisible to humans. But how can the civilization make that thing? In some visions, the civilization can close their star in the closed ball, called the Dyson sphere. If the sphere is closed. That makes the civilization invisible to outsiders. 

The reason and motivation for building giant megastructures can be overpopulation. But those structures can also used to control things like energy production. The giant Dyson spheres can press plasma into artificial stars. And they can press stars and planets into the artificial black holes. 

The civilization can close things like red dwarfs in the sphere and can control their energy production using laser or microwave systems. The sphere stores energy that the star produces and then sends it back in the form of microwaves or laser beams. That helps to control the star's brightness. 

Theoretically, giant Dyson spheres can cover entire stars and entire solar systems. Those giant structures can help alien civilizations use all the energy that their star can create. Giant Dyson spheres can also be used to control the star of the hypothetical alien civilization. 

In some models, the giant ring orbits the Dyson spheres. That ring can used as the giant space sling that throws the craft to space. 


There could be three types of Dysion spheres. 


1) Fully closed ball that can close 100% of the star's radiation inside it. 


2) The whisk-looking structure. In some models, those belts or rods can turned into ring-shaped structures. That means this kind of Dyson sphere can adjust its shape. 


3) The large satellite group. Those satellites can adjust the central star's brightness by shooting it with lasers or microwaves. 


The Dyson spheres can also used to create artificial stars or press stars and planets into black holes. But the fact is that Dyson spheres are hypothetical structures. 


If that sphere does not send any radiation through it. It is invisible to outsiders. 


But have we detected some kind of Dyson spheres? The thing is that there is a structure in the universe. That we can call the "dark matter star". The dark dark matter star is an invisible structure in the universe. That structure is too light to be a black hole. That structure can be the dark matter gob. But it could also be the large Dyson sphere that can close some stars inside it. 

Another thing that can prove a Dyson sphere is the smallest stars in the universe. Some think that those stars that are smaller than Jupiter could be artificial. 

There is no straight evidence of those hypothetical alien megastructures. But it's good to see that also starting to talk about those things freely. The Dyson spheres are things that can uncover some alien civilizations.

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.

The Pentagon published its new UFO report and found no evidence of the alien connection.

SR-71 The Pentagon says that they have no evidence of the UFO's extraterrestrial origins. But even if there is no evidence that aliens are behind the UFOs, we must keep our minds open. The alien message to radio telescopes is not a spacecraft from another solar system. And spacecraft from another solar system can be probed. Nobody confesses to holding alien spacecraft, but the world is full of extremely rare aviation vehicles. And that means UFOs are true, but aliens are not. Says Pentagon. So if most of those UFOs are the Pentagon's secretive military projects. There are still many interesting things.  That means the famous Roswell Alien, which has the main role in the footage Alien Autopsy can be the human-looking robot. That explains rubber and other things in that character. So the film is real, but the object of the autopsy is a robot, not an alien. You can search this film from the net using keywords: "alien autopsy".  Maybe most of the UFOs are Pentagon's h
