Bright GRB and interesting exoplanet.



"Astronomers think a long GRB (gamma-ray burst) arises from a massive, rapidly rotating star when its core runs out of fuel and collapses, forming a black hole in the star’s center. In this artist’s concept, two jets emerge from the dying star and interact with surrounding gas and dust.

The new gamma-ray burst (GRB) unveils the secrets of the formation of black holes.


NASA captured the brightest gamma-ray burst near a star that collapsed into a black hole. The gamma-ray burst might happen when the star explodes, and then the forming black hole starts to pull those supernova remnants into it. In that model suddenly forming effect causes an effect. Where those particles fall back to the gravity center.

That causes a situation in which some particles impact each other. And there forming an electromagnetic vacuum there more material falls. The black hole will not form immediately. The plasma just starts to rotate around the magnetic axle. And then there happens extremely powerful nuclear fusion. In that moment energy level in that plasma rises very high.



The question of why the supernova can form the GRB (Gamma-Ray Burst) can be answered from the model that during that explosion, there is first a large group of small black holes. This period might last a couple of microseconds. That period is short but the GRB forms in that moment. And after that process. There was one large black hole remaining after the star fell.

The mystery has been how the supernova can form GRB. That thing requires lots of energy. And things like colliding neutron stars and black holes can create GRB. The supermassive black holes are the known static gamma-ray sources. Stellar black holes send X-ray impulses.





Astronomers have discovered a super-Earth, TOI-715 b, in a potentially habitable zone around a red dwarf star 137 light-years away. This planet, which is about one and a half times the size of Earth, could support liquid water if other conditions, such as a suitable atmosphere, are met. (Artist’s concept.)

And again.

The new super-earth was detected in a habitable zone of 137 ly from Earth. The new object called TOI-715 b orbits a red dwarf. So there is not a very good chance that on that exoplanet will be intelligent lifeforms. The TOI-715 b is the superearth that can theoretically maintain some kind of lifeforms like algae or bacteria. But the problem is that the planet is locked. The TOI-715 b is one of the promising objects there could be some primitive life forms.

But otherwise thinking the TOI-715 and other exoplanets that orbit red dwarf stars can offer a very good place for a civilization that is quite advanced. In those scenarios, civilization would form a planet that orbits a blue star. The base element in this model is that the civilization realizes that their star will destroy their home planet quite soon. So they put all their energy and colonize the red dwarf that is about 0,5-2 light years away from their home planet.

Locked planets offer a good position for solar cells and wind energy. The idea is that advanced civilizations can make that journey using massive and slow arcs that transport their entire population into another solar system. But that is only one of the models that was created for finding intelligent 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.

Image
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
