Can dark matter be some kind of Rydberg state?


"This artist’s concept shows a pulsar, which is like a lighthouse, as its light appears in regular pulses as it rotates. Pulsars are dense remnants of exploded stars, and are part of a class of objects called neutron stars.

Astronomers detect dark matter using neutron stars. But can we ever see dark matter itself? Weakly interacting massive particles, or WIMPs are a mystery. The thing that dark matter exists near centers of galaxies and black holes tells us that this thing follows the rule of the gravity. And because dark matter seems to pile up near gravitational centers tells us that the WIMPs should be real. 

In some models, the WIMP is an extremely large particle or particle group. That means the superstrings that form the whisk-looking structure are at a very long distance from each other. That means the internal structure of that material is so thin that energy travels straight throw it. The reflection that comes from those superstrings would be so weak, that we cannot see that reflection. 

The sombrero model can tell that the gravity effect of the WIMP is so powerful, that its energy hill cannot rise higher than the edge of a gravitational pothole. But there is also a model, that the WIMP is some Rydberg's state of atoms. 



Wikipedia says that The Rydberg atom means. "A Rydberg atom is an excited atom with one or more electrons that have a very high principal quantum number, n. " (Wikipedia, Rydberg atom). That means the electron between the electron shells is at a higher energy level than it should. The Rydberg state can also mean a situation that is seen in Bose-Einstein condensate. The most out electron shell can be very far away from the atom's nucleus. That makes the second far electron rise at a higher energy level than the most out an electron. 

"The higher the value of n, the farther the electron is from the nucleus, on average. Rydberg atoms have a number of peculiar properties including an exaggerated response to electric and magnetic fields, long decay periods and electron wavefunctions that approximate, under some conditions, classical orbits of electrons about the nuclei. The core electrons shield the outer electron from the electric field of the nucleus such that, from a distance, the electric potential looks identical to that experienced by the electron in a hydrogen atom. (Wikipedia, Rydberg Atom)

There is a theoretical possibility that the atom's nucleus can go out from its electron cloud. And that thing is one of the most theoretical things that can happen to an atom. And nobody saw a situation. Where the atom's nucleus orbits an electron cloud. But that extreme situation can be possible. 

What if the quarks in an atom's nucleus form a similar thing as Rydberg atoms? What if the distance of quarks can be very long? Can that thing make the WIMP possible? The WIMP means particle, that can interact only through the gravitation. 

But maybe it's possible. That Rydberg atom-type phenomenon can formed in some other subatomic structures than electrons. And the question is can Rydberg-state form between things like quarks? But those things are only the theories of what the WIMP can be.

The hydrogen-burning supernovas are interesting models.

"Researchers discovered a significant magnesium anomaly in a meteorite’s dust particle, challenging current astrophysical models and suggesting new insights into hydrogen-burning supernovas. (Artist’s concept.)Credit: SciTechDaily.com" (ScitechDaily, Rare Dust Particle From Ancient Extraterrestrial Meteorite Challenges Astrophysical Models) If the star is too heavy when its fusion reaction starts, it can detonate just at that moment, when its fusion starts. If the collapsing nebula is heavy enough, it can form a black hole straight from the nebula. But if the nebula's gravity is too heavy to  form  the blue giant or too  small  it can collapse  straight  into a black hole . If  the forming star is a little bit larger than the blue supergiants. It can explode immediately when the fusion starts.    The theory of hydrogen-burning supernovas consists  model  of the giant stars that explode immediately after their fusion starts. When the...

The ancient galaxy mirrors the Milky Way.

"This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc galaxy existing only 700 million years after the Big Bang. This makes it the most distant and earliest known Milky Way-like galaxy found to date. Credit: ALMA (ESO/NAOJ/NRAO)/L. Rowland et al./ESO/J. Dunlop et al. Ack.: CASU, CALET" (ScitechDaily, Astronomers Baffled by Ancient Galaxy That Mirrors Modern Milky Way) Researchers found the youngest Milky Way-type galaxy. The distance to the galaxy is enormous. And the light that comes from that galaxy named REBELS-25 comes from the Universe that is only 700 million years old. The distance to that galaxy is enormous about 236 billion light years. And that means it's a very dista...

Transcendence, or the ability to transcendent thinking may grow in teen's brains.

   "New research has discovered that transcendent thinking, which involves analyzing the broader implications of situations, can foster brain growth in adolescents. This form of thinking enhances brain network coordination, impacting developmental milestones and future life satisfaction. The study emphasizes the need for education that encourages deep, reflective thought, underscoring the critical role of adolescents in their own brain development". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) "Scientists at  USC Rossier School of Education’s Center for Affective Neuroscience, Development, Learning and Education (CANDLE) have discovered that adolescents who grapple with the bigger meaning of social situations experience greater brain growth, which predicts stronger identity development and life satisfaction years later".
