I think we're gonna make the Free State of Valhalla on Earth; Jupiter.
I think Gaia is going quantum Jupiter.You can all go to Epstein's New Moon Prometheus.

"The western states are on their own. IF they were willing to support my rule, we could probably do something. But, they won't. God rest their souls."
So said the Trumpian Heir in February of 2040 after the great quakes devastated the entire west coast.
Then began the journey home ... to safety? Or to ruin?
Read the Apocrypha of the Knight Shamans for an edge-of-your-seat character-driven tale of survival and leadership in evil days.

Gaia hypothesis (Evolution 🧬)
The Gaia hypothesis, also known as the Gaia theory, Gaia paradigm, or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating complex system that helps to maintain and perpetuate the conditions for life on the planet. The Gaia hypothesis was formulated by the chem...

@Huntn00 @cwicseolfor I don't believe any such plan would ever be agreed. We aren't sensible creatures, like the ten-spined sticklebacks, that all become #gay when their #food #supply is too low to #support their #population, & only become #straight again when it can feed them all, so it will be #Gaia that will impose her #solution on us. We WON'T like it!

What Does It Mean to Awaken in a Broken World?
The Knight Shamans are more than mystics in a post-apocalyptic landscape. Their journey begins with a question: what happens when people awaken to themselves, to the spirit world, and to the responsibilities of rebuilding society?
In The Apocrypha of the Knight Shamans, awakening is never a single moment. It is a process—a difficult movement from inherited assumptions toward a deeper understanding of self, community, and the unseen forces shaping both.
The world of the series has already been shattered by earthquakes, political conflict, social collapse, and forgotten dangers. Yet the books are not only about surviving catastrophe. They ask what survivors do next. When roads, institutions, and familiar rules disappear, people must decide which parts of the old world deserve to be restored and which should be left behind.
The inner awakening
A Knight Shaman must first awaken the spirit society has buried beneath programming, fear, and cultural expectations. That awakening is personal, but it is never merely private. Rodney’s ability to see the spirits of the dead, Peter’s emerging shamanic talent, and Justin Earl Knight’s struggles with his own demons all reveal different paths toward self-knowledge.These characters do not receive simple answers. Their gifts come with obligations. To see more clearly is also to carry more responsibility. A shaman must confront the Other Worlds, interpret what is found there, and determine how spiritual knowledge can guide living people without becoming another form of control.
Demons to banish. Fallen Angels unmasked. Pantheons falling where others are rising. Enemies become lovers and Lovers become enemies.
This three-book omnibus is in hardcover and costs less than the three separate paperback versions.

Most journeys through time begin with a destination. In CERNON, Book One of an 8 book series, the destination is only the beginning of the mystery.
Sophia Shaman of the Elk Creek Tribe enters the past seeking answers about Cernon’s origin. She expects to uncover an old story, perhaps a forgotten event or a hidden truth buried beneath layers of myth. Instead, she finds herself in a world tens of thousands of years removed from her own, where an ice age is approaching and a small tribe is fighting to survive.
The deeper Sophia moves into this ancient world, the less stable the idea of history becomes. Her journey is not a simple visit to a distant era. It is an encounter with memory itself. Cernon tells her, “You were never really there. You were riding my memories.”
The statement changes everything. Can a memory carry consequences across time?
These questions give the novel one of its central themes: the uncertain relationship between observer and participant. Sophia arrives intending to help, but her presence may be more significant than she realizes. Her compassion draws her toward the endangered tribe, yet every choice she makes could alter the meaning of Cernon’s beginning. The line between discovering history and creating it grows increasingly thin.
Against the pressure of the coming ice age, the novel places enormous philosophical questions inside a very physical struggle. The tribe needs shelter, protection, and hope. Sophia must respond to immediate danger while confronting the possibility that she is part of a much larger pattern.
That tension makes the story more than an adventure into the distant past. It becomes a meditation on whether time carries us forward—or whether we sometimes become the tools through which time reshapes the world.

Spirituality & Religious Studies @spiritualityreligiousstudies.wordpress.com@spiritualityreligiousstudies.wordpress.com ·Hephaestus
Author’s Note: This post has mentions of (g)rape. If this is triggering, please go on to 1 of our other posts.
He’s the Greek god of artisans, blacksmiths, carpenters, craftsmen, fire, metallurgy, metalworking, sculpture, & volcanoes.
In Greek mythology, Hephaestus was the son of Hera, either on her own or her husband/brother, Zeus. He was cast off Mount Olympus by his mom, Hera, because of his lameness, the result of a congenital impairment. Or, in another account, by Zeus for protecting Hera from his advances.
As a smithing god, Hephaestus created all the weapons of the gods on Olympus. He served as the blacksmith of the gods & was worshipped in the manufacturing & industrial centers of Greece, particularly Athens. The cult of Hephaestus was based in Lemnos. Hephaestus’ symbols are a smith’s hammer, anvil, & a pair of tongs. In Rome, he was equated with Vulcan.
In Hesiod’s Theogony, Hera gives birth to Hephaestus on her own, out of revenge for Zeus having, without her, fathered Athena (the daughter of Zeus & Metis). Apollodorus similarly states that Hera gives birth to Hephaestus alone. Though according to Homer, Hephaestus is 1 of the kids of Zeus & Hera.
Some sources state that the origin myth of Hephaestus was that of a “daemon of fire coming up from the Earth,” that he was also associated with gas “which takes fire & burns & is considered by many people to be divine” & that only later was a volcano considered Hephaestus’ smithy.
He was associated by Greek colonists in southern Italy with the volcano gods Adranus (of Mount Etna) & Vulcanus of the Lipari islands.
The 1st-century sage, Apollonius of Tyana, is said to have observed, “there are many other mountains all over the earth that are on fire, & yet we should never be done with it if we assigned to them giants & gods like Hephaestus.” Nevertheless, Hephaestus’ domain over fire goes back to Homer’s Iliad, where he uses flames to dry the waters of the Scamander River in order to force its eponymous deity, who was attacking Achilles, to retreat.
His favorite place in our mere mortal world was the island of Lemnos. He liked to live among the Sintians. But he also repeatedly went to other volcanic islands like Lipari, Imbros, & Sicily, which were called his abodes/workshops. In 1 version of events, Hera rejects, then ejects Hephaestus from Olympus/the heavens because of his congenital impairment. (It’s implied that his congenital disability is because of Zeus & Hera’s familial relationship, i.e. brother & sister.)
Because of Hera’s actions, he fell into the ocean & of Hera’s actions, he fell into the ocean & was raised by Thetis (Achilles’ mom & 1 of the 50 Nereids) & Eurynome, the Oceanid. In another version, Hephaestus, attempting to rescue his mom from Zeus’ advances, was cast down to earth by Zeus, not Hera!
He (Hephaestus) was cast down for 1 whole day & landed on the island of Lemnos. On Lemnos, he was cared for & taught to be a master craftsman by the Sintians. Later writers describe his physical disability as a result of his 2nd fall. While Homer makes him disabled from birth.
Hephaestus was 1 of the Olympians who came back to Olympus after being exiled. In an archaic story, Hephaestus wanted revenge against Hera for rejecting him by forging her a magical golden throne, which, when she sat on it, didn’t let her stand up again.
The other gods begged Hephaestus to return to Olympus to let her go. But he refused, saying, “I’ve no mom.” It was Ares who undertook the task of fetching Hephaestus at 1st. But he was threatened by the fire god with torches. At last, Dionysus (the wine god) fetched him, got him drunk on wine, & took the subdued smith back to Olympus on the back of a mule, accompanied by revelers.
According to Hyginus, Zeus promised anything to Hephaestus to free Hera. Hephaestus asked for Athena’s hand in marriage (urged by Poseidon, who was hostile toward Athena), leading to his attempted (g)raping of the goddess, who rejected his advances.
In another version, he demanded to be married to Aphrodite to release Hera, & his mom fulfilled the request. Hephaestus had his own palace on Olympus, containing his workshop with an anvil(s) & 20 bellows that worked at his bidding.
He crafted much of the magnificent equipment of the gods, & almost any finely wrought metalwork imbued with powers that appears in Greek myth is said to have been forged by Hephaestus. He designed all the thrones in the Olympian palace, the Aegis breastplate, Hermes’ (not the fashion house) winged helmet & sandals, Aphrodite’s famous girdle, Eros’ bow & arrows, Helios’ chariot, Heracles’ bronze clappers, & the shoulder of Pelops.
Hephaestus also created the gift that the gods gave to mankind: the 1st woman, Pandora, & her pithos (a large jar)/box. In some versions, Prometheus stole the fire that he gave to man from Hephaestus’ forge. Hephaestus gave to the blinded Orion his apprentice Cedalion as a guide. In later accounts, Hephaestus worked with the Cyclopes Brontes, Steropes, & Arges, who were highly skilled blacksmiths in their own right & forged Zeus’ thunderbolts, Poseidon’s trident, & Hades’ helmet of darkness/invisibility.
According to Homer, Hephaestus built automatons of metal to work for him or others. This includes tripods with golden wheels, able to move at his wish in & out of the assembly hall of the celestials; & “handmaidens wrought of gold in the semblance of living maids,” who had “understanding in their hearts, & speech & strength,” as a gift of the gods.
They moved to support Hephaestus while walking. Hephaestus also put golden & silver lions & dogs at the entrance of the palace of Alkinoos in such a way that they could bite the invaders. These guard dogs didn’t age or perish. (So does this mean that they could possibly still be around, hidden somewhere? Like the Nag Hammadi library.)
A similar golden dog was set by Rhea to guard the infant Zeus & his nurse (the goat Amaltheia) on the island of Krete/Crete. Later, Tantalus was said to have stolen the automaton when it guarded Zeus’ temple, or to have persuaded Pandareos to steal it for him.
Later texts attempt to replace the automaton with the idea that the golden dog was actually Rhea, transformed by Hephaestus. Hephaestus fought against the giants & killed Mimas by throwing molten iron at him. He also fought another giant, Aristaeus, but he fled.
During the battle, Hephaestus fell down exhausted & was picked up by Helios in his chariot. As a gift of gratitude, Hephaestus forged 4 ever-flowing fountains & fire-breathing bulls for Helios’ son Aeetus. At the marriage of Peleus & Thetis, Hephaestus gave a knife as a wedding present.
When the Trojan War began, Hephaestus sided with the Greeks & forged the armor of Achilles, the cuirass of Diomedes, & Agamemnon’s staff of office. But Hephaestus was also worshipped by the Trojans & saved 1 of their men from being killed by Diomedes.
Though she was married to Hephaestus, Aphrodite had an affair with Ares, the god of war. Eventually, Hephaestus discovered Aphrodite’s affair through Helios, the all-seeing sun (We’re gonna circle back to this. Keep this in mind.), & planned a trap during 1 of their trysts.
While the lovers lay together in bed, Hephaestus ensnared them in an unbreakable chain-link net so small as to be invisible & dragged them to Mount Olympus to shame them in front of the other gods for retribution. The gods had a good laugh at the sight of these unclothed adulterers. Poseidon persuaded Hephaestus to free them in return for a guarantee that Ares would pay the adulterers’ fine, or Poseidon would pay it himself.
In The Odyssey, Hephaestus says he would give Aphrodite back to Zeus & demand back his bride price. Some versions of the myth state that Zeus didn’t return the dowry. In fact, Aphrodite “simply charmed her way back again into her husband’s good graces.”
In The Iliad, Hephaestus is described as being married to the Grace named Charis during the events depicted in the Trojan War. While in Theogeny, he’s married to the Grace named Aglaea, with no indication of having ever been married to Aphrodite.
In Dionysiaca by Nonnus explicitly stated that, though Hephaestus & Aphrodite were once married (she’s referred to as his “ancient wife”). They’ve since separated & Hephaestus is now married to Charis.
Here’s the keep-in-mind part: In a later detail, Ares put the young soldier, Alectryon, by their door to warn them of Helios’ arrival, as he suspected that Helios would tell Hephaestus of Aphrodite’s infidelity if the 2 were discovered. But Alectryon fell asleep on guard duty. Helios finds the 2 & alerts Hephaestus. Ares, in a rage, turned Alectryon into a rooster, which always crows at dawn when the sun is about to rise.
The Thebans said that the spicy time union of Ares & Aphrodite produced Harmonia. But that of the union of Hephaestus with Aphrodite, there’s usually no issue. Because Harmonia was conceived during Aphrodite’s marriage to Hephaestus, for revenge, on Harmonia’s wedding day to Cadmus, Hephaestus gifted her with a finely worked but cursed necklace that brought immense suffering to her descendants, culminating in Oedipus. (Check out our post on Oedipus.)
An Athenian founding myth tells the city’s patron goddess, Athena, refused a union (spicy time) with Hephaestus. Pseudo-Apollodorus records an archaic legend, which claims that Hephaestus once tried to (g)rape Athena. But she pushed him away, causing him to ejaculate on her thigh.
Athena wiped the happy time juice off using a tuft of wool. She tossed it into the dust. This impregnated Gaia (his own great-grandma). This caused her to give birth to King Erichthonius, whom Athena adopted as her own kid.

It's not difficult to extrapolate from an understanding of #homeostasis as noted in individuals to population and ecological community levels. Alas, #fossilfuel companies encouraged #Lovelock and #Margulis in their #Gaia research, as it was surmised their findings would lull the general public to believe the earth would self-regulate regardless of levels of pollution. It probably did help with the propaganda.
To maintain homeostasis, however, always requires an #EROEI. We have dysregulated the ecological homeostasis. When it costs as much to sell and ship an item as we can make from doing so, we will stop doing so. Ships, aircraft, trains, barges and trucks are vulnerable to this. WE are vulnerable to this. >>

If this isn't evidence for the Gaia hypothesis, I don't know what would be. It's literally an induced, prophylactic immune response to one of the most unsustainable food systems humans have. Now if we could just have a highly contagious, otherwise symptomless STD that (after a variable incubation period) caused sterility and a distinctive facial scar for any human attempting to use a car or lorry...

squirrel; its all it take to get my attention:-)
Just some relief from the news in the US.
While taking photos at local pond I caught a squirrel showing how useful white spots were. I guess that is why lots of animals have them, bobcats, fawns, etc

Weekly Update from the Open Journal of Astrophysics – 25/04/2026
So here we are again, on a Saturday morning, with another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further five papers, bringing the number in Volume 9 (2026) to 87 and the total so far published by OJAp up to 535.
I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter (which nobody should be using); these announcements also show the DOI for each paper.
The first paper to report this week is “Bayesian Cosmic Void Finding with Graph Flows” by Leander Thiele (U. Tokyo, Japan). This was published on Monday 20th April in the folder Cosmology and Nongalactic Astrophysics. The paper presents a method using a deep graph neural network to identify cosmic voids in sparse galaxy surveys, improving upon traditional deterministic algorithms by considering the problem’s probabilistic nature. The overlay is here:
You can find the officially accepted version on arXiv here and the announcement on Fediverse here:
https://fediscience.org/@OJ_Astro/116435864086025246
The second paper for this week, published on Wednesday 22nd April in the folder Astrophysics of Galaxies, is “Sifting for a Stream: The Morphology of the 300S Stellar Stream” by Benjamin Cohen (U. Chicago, USA) and 20 others distributed around the world. This study analyzes the morphology of the $300S$ stellar stream, revealing three density peaks, a possible gap, and a kink, suggesting significant influence from the Large Magellanic Cloud on its structure.
The overlay for this one is here:
The official version of the paper can be found on arXiv here and the Fediverse announcement here:
https://fediscience.org/@OJ_Astro/116447005556180402
Next one up, the third paper of the week, is “IRMaGiC: Extending Luminous Red Galaxy Selection into the Infrared with Joint Rubin Observatory’s Large Survey of Space Time and Roman’s High Latitude Imaging Survey” by Zhiyuan Guo & Chris. W. Walter (Duke U., USA) and Eli S. Rykoff (Stanford U., USA) on behalf of the LSST Dark Energy Science Collaboration. This was published on Wednesday April 22nd in the folder Cosmology and Nongalactic Astrophysics. The paper introduces IRMaGiC, an algorithm that improves the selection and redshift estimation of Luminous Red Galaxies (LRGs) by incorporating infrared data, enhancing future cosmological surveys.
The overlay for this one is here:
The final, accepted version can be found on arXiv here and the Mastodon announcement is here:
https://fediscience.org/@OJ_Astro/116447067337351283
The fourth paper this week, published on Thursday April 23rd, is “The Diagnostic Temperature Discrepancy as Evidence for Non-Maxwellian Coronal Electrons” by Victor Edmonds (Final Stop Consulting, USA). This paper, in the folder Solar and Stellar Astrophysics, presents two methods of measuring electron temperature in the quiet solar corona yielding different results, suggesting non-Maxwellian electron velocity distributions may be responsible for the discrepancy.
The overlay is here:
The finally accepted version of this paper can be found here and the Mastodon announcement follows:
https://fediscience.org/@OJ_Astro/116452775389963618
The fifth and final paper for this week was published on Friday 24th April in the folder Astrophysics of Galaxies. The title is “Galaxy evolution in the post-merger regime. IV – The long-term effect of mergers on galactic stellar mass growth and distribution” by Sara L. Ellison (U. Victoria, Canada) and Leonardo Ferreira (Universidade Federal do Rio Grande, Brazil). This study uses a large sample of post-merger galaxies to demonstrate that galaxy mergers trigger significant and extended stellar mass growth in their central regions, independent of stellar population modelling.

IV – The long-term effect of mergers on galactic stellar mass growth and distribution” by Sara L. Ellison (U. Victoria, Canada) and Leonardo Ferreira (Universidade Federal do Rio Grande, Brazil). This study uses a large sample of post-merger galaxies to demonstrate that galaxy mergers trigger significant and extended stellar mass growth in their central regions, independent of stellar population modelling.

🎭 Bueno, por fin hay cartel para el acto de entrega de premios del certamen de microteatro "Vila de Verdú" (sábado 25 de abril), donde han tenido a bien concederme el 3er. premio por una obrita colapsista titulada "Algoritmo Final". Si alguien andar por la comarca de Urgell o se quiere acercar desde Lleida... por allí estaremos sufriendo un síndrome del impostor 'nivel dios' en medio de la buena gente del teatro 😅

Scientists find evidence of faraway worlds colliding
Astronomers say unusual readings from a star system 11,000 light-years away suggest that two of the planets circling the star crashed into each other, creating a huge, light-obscuring cloud of rocks and dust.The analysis, laid out this week in a paper published

ASTRONOMY MILESTONE: Scientists have solved the 'mass-distance degeneracy' problem, using #GravitationalLensing observed from Earth & the #Gaia space telescope to pinpoint a #RoguePlanet's exact mass & location. The Saturn-sized object, 9,785 light-years away, was likely violently ejected from its star system. This confirms theories of a vast, hidden population of nomadic planets & opens a new era for #Astronomy with upcoming telescopes like #nancygraceroman

Polacy znowu patrzą w niebo. Projekt OGLE odkrył „samotną planetę” wędrującą przez naszą galaktykę
W cieniu targów CES i premier gadżetów, polscy astronomowie z Uniwersytetu Warszawskiego dokonali odkrycia wagi ciężkiej (dosłownie).
Zespół programu OGLE namierzył swobodną planetę, która nie krąży wokół żadnej gwiazdy, lecz samotnie przemierza Drogę Mleczną.
Samotny wędrowiec o masie 70 Ziem
Odkrycia dokonano w Obserwatorium Astronomicznym Uniwersytetu Warszawskiego pod kierownictwem prof. Andrzeja Udalskiego. Obiekt, który udało się namierzyć, to tzw. planeta swobodna (rogue planet). To ciało niebieskie, które zostało wyrzucone ze swojego macierzystego układu i teraz dryfuje w przestrzeni międzygwiezdnej.
Astronomowie wyliczyli, że planeta ta jest 70 razy cięższa od Ziemi. To stawia ją w kategorii gazowych olbrzymów (dla porównania: Jowisz jest ok. 318 razy cięższy od Ziemi, a Saturn 95 razy).
Kosmos w wersji Smart Home. Jak inteligentne teleskopy sprawiły, że nie musisz marznąć pod gwiazdami
Jak dostrzec coś, co nie świeci?
To jest najciekawsza część techniczna. Samotne planety są ciemne i zimne, więc nie da się ich zobaczyć przez teleskop w tradycyjny sposób. Polacy wykorzystali zjawisko mikrosoczewkowania grawitacyjnego.
Gdy niewidoczna planeta przechodzi na tle odległej gwiazdy, jej grawitacja działa jak soczewka – zakrzywia i wzmacnia światło tej gwiazdy. To właśnie to pociemnienie i pojaśnienie zarejestrowali naukowcy. Co kluczowe – zjawisko zaobserwowano jednocześnie z dwóch perspektyw:
- Z Ziemi (teleskop OGLE w Chile).
- Z kosmosu (satelita Gaia należący do ESA).
Dzięki temu (tzw. mikrosoczewkowanie paralaksy) udało się precyzyjnie wyznaczyć odległość i masę obiektu, co w astronomii jest niezwykle trudne.
OGLE – polska duma
Warto przypomnieć, że projekt OGLE (Optical Gravitational Lensing Experiment) to jeden z największych sukcesów polskiej nauki. Działający od ponad 30 lat program regularnie dostarcza przełomowych danych o strukturze Drogi Mlecznej i planetach pozasłonecznych. Tym odkryciem Polacy potwierdzają teorię, że nasza galaktyka może być pełna takich „samotnych wędrowców”.

In Greek mythology, #Oceanus is the #Titan god of the great river that encircled the world, believed to be the source of all seas, rivers, and springs. He was one of the eldest Titans, born from #Gaia and #Uranus.
Unlike most of his Titan siblings, Oceanus stayed out of the great war between the Titans and the #Olympians. With his wife and sister #Tethys, he fathered thousands of river gods and ocean #nymphs known as #Oceanids.

Who is Pontus
In Greek mythology, #Pontus is the primordial god of the Sea, one of the first beings to emerge from #Gaia, the Earth. He represents the deep, unshaped waters that existed before the seas were ruled by #Poseidon or filled with life.
With Gaia, Pontus fathered many ancient sea deities, including #Nereus, #Thaumas, #Phorcys, #Ceto, and #Eurybia. Together, they shaped the mysteries and creatures of the ocean.

Weekly Update from the Open Journal of Astrophysics – 18/10/2025
It’s time once again for the usual Saturday update of the week’s new papers at the Open Journal of Astrophysics. Since the last update we have published six more papers, which brings the number in Volume 8 (2025) up to 156, and the total so far published by OJAp up to 391.
I’d like to encourage people to follow our feed on the Fediverse via Mastodon (where I announce papers as they are published, including the all-important DOI) so this week I’ll include links to each announcement there.
The first paper to report is “Shot noise in clustering power spectra” by Nicolas Tessore (University College London, UK) and Alex Hall (University of Edinburgh, UK). This was published in the folder Cosmology and NonGalactic Astrophysics on Tuesday October 14th 2025. This presents a discussion of the effects of ‘shot noise’, an additive contribution due to degenerate pairs of points, in angular galaxy clustering power spectra. Here is a screen grab of the overlay:
