Maybe mysterious little red dots at the edge of the universe are black hole stars.

 Maybe mysterious little red dots at the edge of the universe are black hole stars. 


"Artist’s impression of a black hole star (not to scale). Mysterious tiny pinpoints of light discovered at the dawn of the universe may be giant spheres of hot gas that are so dense they look like the atmospheres of typical nuclear fusion-powered stars; however, instead of fusion, they are powered by supermassive black holes in their center that rapidly pull in matter, converting it into energy and giving off light. Credit: T. Müller/A. de Graaff/Max Planck Institute for Astronomy" (ScitechDaily, Mysterious “Universe Breaker” Red Dots Could Be Black Holes in Disguise)

The little red dots at the edge of the universe could be so-called black hole stars. If that thing is true, those red dots would be the most fundamental things in the world. The black hole stars, or so-called quasi stars, would be the most interesting things in the universe. The quasi-star could form around the small back hole. In the early universe, those black holes could form when the so-called Schwinger effect formed a material point. 

That formed a singularity. And then those black holes started to pull material into them. There is a possibility that black holes pull particles they forming a stellar-shaped structure around the event horizon. Those hydrogen atoms are locked around the black hole. Those hydrogen atoms can form a spinning layer in the distance where the escaping velocity is the same as that atom’s speed.

The quasi-star, or black hole star, is like other stars if we see them outside. But they could be far larger than regular stars. If those famous red dots are quasi-stars that help to calculate other black holes and black hole-based structures. Things like extremely small black holes that can hide in ball-shaped asteroids are waiting for their finder. The quasi-stars will help to fill in the puzzle about the black holes. Those things will not be fundamental, and intermediate mass black holes are not fundamental. But they will confirm theories and models of back holes and their formation. 

The quasi-stars would not exist in our universe. The thing that forms the structure is the interaction between layers that form that object. The energy from inner structures interacts with the outer structure. Those structures push each other away. When those structures' temperatures turn lower, that breaks the quasi-star. 


"An illustration shows the JWST in space next to its observations of some of the earliest galaxies ever seen, the so-called "little red dots." (Image credit: NASA, ESA, CSA, STScI, Dale Kocevski (Colby College)/ Robert Lea (created with Canva))" (Space.com, James Webb Space Telescope sees little red dots feeding black holes: 'This is how you solve a universe-breaking problem') 

If those little red dots (LRD) are black holes that formed before galaxies or even material that could mean that first were so-called “Kugelblitz”-black holes that formed straight from wave movement. Then those kugelblitz black holes formed galaxies around them. That means it’s possible that black holes formed before matter. 





"Size comparison of a hypothetical quasi-star to some of the largest known stars."(Wikipedia, Quasi-star)

“As a quasi-star cooled over time, its outer envelope would become transparent, until further cooling to a limiting temperature of 4,000 K (3,730 °C). This would mark the end of the quasi-star's life since there is no hydrostatic equilibrium at or below this limiting temperature. It would then dissipate without a supernova, leaving behind an intermediate-mass black hole. These intermediate-mass black holes are theorized as the progenitors of modern supermassive black holes, and would help explain how supermassive black holes formed so early in the history of the universe.” (Wikipedia, Quasi-star)

The energy that this quasi-star shines is energy that forms in the black hole’s material disk, and in the case that the back hole pulls that radiation’s wavelength longer. The extreme gravity causes a virtual redshift because gravity stretches light. That means quasi-stars should be red. The massive gravitational redshift will pull all radiation longer than it should be. Or to the red side of the electromagnetic spectrum. 

So the black hole can pull X-rays. And gamma-ray wavelengths turn longer. And that thing causes an interesting model. That can make a black hole invisible because extreme gravity pulls electromagnetic radiation’s wavelength so long. If the gravity is strong enough, that thing can turn even gamma-rays into radio waves. 

That means that there is a possibility that black holes’ gamma- and X-rays are also a result of some, yet unknown, radiation’s wavelength stretch.  A black hole's environment has a wavelength longer than it should. This means that the black hole seems to be at a longer distance than it actually is. Otherwise, if those objects are on the other side of the universe, the redshift would be strong anyway.

A new mysterious object has been discovered at the edge of the solar system.

 A new mysterious object has been discovered at the edge of the solar system. 

“A composite image showing the five dwarf planets recognized by the International Astronomical Union, plus the newly discovered trans-Neptunian object 2017 OF201. Credit: NASA/JPL-Caltech; image of 2017 OF201: Sihao Cheng et al.” (ScitechDaily, Astronomers Discover Mysterious New World at Edge of the Solar System

The JWST telescope discovered a mysterious object, designated 2017 OF201, at the edge of the solar system. That object is one of the so-called trans-Neptunian objects, TNOs. That opens new paths to discover new planets and dwarf planets in our solar system. The 2017 OF201 is the dwarf planets. These are introduced in the image. Above this text. 

Most of those dwarf planets are found in the Kuiper Belt, and only Ceres is in the asteroid belt. That means there can be many dwarf planets hiding in the Kuiper Belt. And that is one of the most interesting questions about dwarf planets. Why are there no dwarf planets in the inner solar system? The dwarf planets are interesting because some of them might have formed as moons of planets. And maybe. Some dwarf planets have been part of larger planets. Those were destroyed in cosmic collisions. 

Most of those dwarf planets are in the Kuiper Belt. That raises the idea that maybe some of those small objects are from other solar systems. Maybe some of those small worlds have been some kind of rogue worlds that slipped away from some red dwarf system, or maybe some nova or supernova threw some of those dwarf planets out of their orbits. Or maybe those things were Uranus’s or Neptune’s moons that some cosmic catastrophe threw out from their orbit. 

The gravity effect that comes from some planets, or some kind of particle beam. Or asteroid impacts can cause an effect. Those small moons that are at a long distance from their planet just go out of their trajectories. The interesting detail in those dwarf planets is that Haumea. Which looks like an egg. It is larger than the ball-shaped Ceres. The shape of Haumea tells. that it has been fast-spinning when it formed. The fast spinning movement stretched that dwarf planet, or there must be some internal effect, like some kind of beam. that stretched that dwarf planet into shape as we see it.

The planet candidate near Alpha Centauri (part II)

    The planet candidate near Alpha Centauri (part II)


"Alpha Centauri A Planet Candidate"

"This artist’s concept shows what a gas giant orbiting Alpha Centauri A could look like. Observations of the triple star system Alpha Centauri using NASA’s James Webb Space Telescope indicate the potential gas giant, about the mass of Saturn, orbiting the star by about two times the distance between the Sun and Earth." (ScitechDaily, NASA’s Webb May Have Found a Planet Next Door. Then It Vanished)

"In this concept, Alpha Centauri A is depicted at the upper left of the planet, while the other Sun-like star in the system, Alpha Centauri B, is at the upper right. Our Sun is shown as a small dot of light between those two stars. Credit: NASA, ESA, CSA, STScI, Robert L. Hurt (Caltech/IPAC)"(ScitechDaily, NASA’s Webb May Have Found a Planet Next Door. Then It Vanished)



The planet candidate in the Alpha Centauri system is an interesting thing. The planet could be a Saturn-type gas giant in a very elliptic trajectory. Alpha Centauri is far brighter than Proxima Centauri, which orbits the binary star system 4 light-years from Earth. The JWST saw a structure that could be an exoplanet, but then it vanished. Maybe there was some kind of eruption in that solar system, and that covered the exoplanet behind it. The Alpha Centauri Ab can face a similar fate as Alpha Centauri Bb, which was a proposed exoplanet near Alpha Centauri B, that is the K-type star. 

There is not enough evidence of the existence of that exoplanet. But there is a possibility that there are many secrets in the Alpha Centauri system, which is the closest solar system, a triple-star system near Earth. The most interesting thing in exoplanet hunting is that those exoplanet candidates are found quite near to us. But if there are big exoplanets hiding in that solar system, that thing opens new paths to the exoplanet hunters. 


"This three-panel image captures NASA’s James Webb Space Telescope’s observational search for a planet around the nearest Sun-like star, Alpha Centauri A. The initial image shows the bright glare of Alpha Centauri A and Alpha Centauri B, and the middle panel then shows the system with a coronagraphic mask placed over Alpha Centauri A to block its bright glare. However, the way the light bends around the edges of the coronagraph creates ripples of light in the surrounding space. " (ScitechDaily, NASA’s Webb May Have Found a Planet Next Door. Then It Vanished)

"The telescope’s optics (its mirrors and support structures) cause some light to interfere with itself, producing circular and spoke-like patterns. These complex light patterns, along with light from the nearby Alpha Centauri B, make it incredibly difficult to spot faint planets. In the panel at the right, astronomers have subtracted the known patterns (using reference images and algorithms) to clean up the image and reveal faint sources like the candidate planet.

Then It Vanished)


The existence of the planets in a triple star system in orbit that goes between those stars means that there could be many exoplanets waiting for their finder. Finding and confirming an exoplanet in the Alpha Centauri primary system will be far, far more difficult than confirming exoplanets near red dwarfs. The last confirmed exoplanet near Proxima Centauri was found in 2022. And the first of that system’s planets was found in the year 2016. There is still, unconfirmed exoplanet candidate near Proxima. And another interesting thing is that astronomers could confirm exoplanets near Barnard’s Star this year. 


"This image shows the Alpha Centauri star system from several different ground- and space-based observatories: the Digitized Sky Survey (DSS), NASA’s Hubble Space Telescope, and NASA’s James Webb Space Telescope. Alpha Centauri A is the third brightest star in the night sky, and the closest Sun-like star to Earth." (ScitechDaily, NASA’s Webb May Have Found a Planet Next Door. Then It Vanished)

"The ground-based image from DSS shows the triple system as a single source of light, while Hubble resolves the two Sun-like stars in the system, Alpha Centauri A and Alpha Centauri B." (ScitechDaily, NASA’s Webb May Have Found a Planet Next Door. Then It Vanished)

The image from Webb’s MIRI (Mid-Infrared Instrument), which uses a coronagraphic mask to block the bright glare from Alpha Centauri A, reveals a potential planet orbiting the star.

Then It Vanished)

Those very dim and lightweight stars start to wobble if there is a small planet orbiting them. But the problem is that large gas giants can cover the changes that small planets cause to red dwarfs' characteristic movement  under their gravitational effect.  So the exoplanets near G- and K-type stars are far difficult to detect, because their brightness covers them. But also, even the most massive objects cannot cause a wobble in those stars' trajectory across the sky. But the exoplanet in the Alpha Centauri primary system could be an interesting discovery.

Are the “red little dots” in the young universe so-called quasi-stars?


"By all rights, they shouldn’t exist. When NASA’s James Webb Space Telescope (JWST) first opened its eyes to the distant past, it spotted hundreds of tiny, brilliant objects glowing red in the infant universe — just 600 million years after the Big Bang. These “little red dots,” as astronomers came to call them, gleamed with such surprising brightness and density that they seemed to defy the basic rules of cosmology."Mysterious red dots may be a peculiar cosmic hybrid between a star and a black hole."(ZmeScience, The Universe’s First “Little Red Dots” May Be a New Kind of Star With a Black Hole Inside")

Little red dots are the first star-shaped objects in the universe. There is a new theory that those little red dots can be so-called quasi-stars. Quasi-stars are hypothetical star-shaped objects that get their energy from the black hole inside them. But can those objects exist in the universe where we live? Or could they exist only in the young universe? 

The hypothetical quasi-stars are star-like objects that get their power from black holes inside them. The idea in quasi-stars is that those black holes can lock particles around the event horizon, forming objects that look like stars. For a long time, researchers thought that the quasi-stars could be very large stars. But there is one thing that makes those quasi-stars more interesting than ever before. That thing is the primordial black hole. In models, primordial black holes can be very small and lightweight. Those low-mass black holes can be very small. Also, things like black hole relativistic jets can press even planets into black holes. 

In Einstein’s models, every particle or object can turn into a black hole. That means there can be very small black holes. The smallest possible black holes, called quantum-size black holes, are quarks or gluons that energy presses into an extremely dense form. In some models, those quantum-size black holes can be in your room. They are so small that they cannot pull particles inside them. But there is a possibility that things like ultra-heavy neutron stars can involve black holes. 



(ZmeScience, The Universe’s First “Little Red Dots” May Be a New Kind of Star With a Black Hole Inside")

The hollow neutron shell can orbit the small black hole. The neutron structure will be locked around the event horizon. That neutron shell can rotate the black hole in a “safe distance”. That kind of object looks like a massive neutron star. But it would involve a black hole. The existence of that kind of thing can be proven in the cases where the neutron star seems too massive. 

Those black holes can be grapefruit-sized, extremely high-energy objects. In some models, quasi-stars are not possible in our universe. Except for those things formed in the early universe. Or there is also the possibility that the low mass black hole can form a quasi-star around it if that thing is in the dense supernova remnant. But there is also a possibility that an extremely low mass black hole can form a planet-shaped shell around it. In that case, the water molecules or things like metal or silicone crystals can form ball-shaped structures around them. 

There is a possibility that some very hot red dwarfs or stars like Spica could be the quasistars. The thing is that the small, low-mass black hole can still lurk in our solar system. And there is a possibility that this exciting object can hide under the icy shell of some dwarf planet. That is the thing that can make the “ninth planet” exist and explain why it cannot be seen from Earth. So there can be something very massive lurking in our solar system.

The first exoplanet that JWST found has no atmosphere.


Above: Artist's impression of exoplanet LHS 475 b

Even the perfect size of an exoplanet doesn't guarantee that there are lifeforms. The exoplanet LHS 475 b is 99% of Earth. But the problem is that it doesn't have an atmosphere at all. Or an extremely thin atmosphere. In the last case, the planet captures star wind around it. That means the extremely thin atmosphere could be external. And that is a remarkable thing. The LHS 475 b orbits the red dwarf star in the Octans constellation 41 light years from Earth. 

 Even large rocky planets can be without an atmosphere. And that expands our knowledge of planets. The exoplanet LHS 475 b is the first exoplanet found by the JWST telescope. But that planet is extremely hostile to lifeforms. So even a large size doesn't guarantee that the exoplanet has an atmosphere. 

But the reason for the lost atmosphere is also interesting. The lack of atmosphere can be the reason for the lack of a magnetic field. In that case, the solar wind blows the atmosphere away. And if that thing is true, there is a possibility that the planet is a so-called "zombie world" where is no radioactive material left. 

And that thing means that the LHS 475 b could be a very old planet. There is a possibility that this exoplanet is sometimes born near some other star. And then supernova- or nova eruption pushed it away from its orbiter. Then another star could capture that rogue planet. Those kinds of things are making LHS 475 b very interesting.

Could there have been UFOs in Earth's orbit in the 1950s?

Aligned, Multiple-Transient Events in the First Palomar Sky Survey could be artificial objects. Or. They could also be some light reflection...
