# esobio: the Benjamin's hypothesis: looking for Dyson spheres around white dwarfs.

<< Dyson spheres (DSR) are the stuff of highly advanced civilizations, commonly thought of as artificial spheres surrounding an entire star.  (..) any of these configurations would have one unique, tell-tale sign—they would change that star's infrared signature. >> 

Benjamin Zuckerman's << theory focuses on scanning white dwarves for anomalous infrared signatures that might indicate that an artificial construct surrounds them. But why white dwarves? Other than being reasonably ubiquitous, they have the distinction of being the end state of stars like our own. >>️

WISE and Spitzer << watched white dwarves with masses around what we would expect our own sun to turn into. They even noticed some incidences of anomalous infrared signatures. However, the researchers thought dust was the most likely cause of those anomalies, and there was no evidence of any DSR. (..) But the absence of evidence is not evidence of absence—it just helps to constrain the likelihood. (..) According to Dr. Zuckerman, with the observations we have already made, we can do a statistical calculation that less than 3% of habitable planets that orbit stars that eventually turn into white dwarves build a DSR around them. Granted, current estimates put the number of habitable planets around G-type stars that might ultimately evolve into white dwarves at 300 million—so there could still be upward of 9 million civilizations that have built a DSR around their white dwarf home star. But for now, the Fermi paradox still holds, and science continues to collect data that will either further constrain the estimates of the number of advanced technological civilizations in our galaxy or prove that we're not alone once and for all. >>️️

PS:  io non sono mai stato testimone di alieni o di manifestazioni di entità aliene. Tuttavia, forse (qui sottolineo forse), potrei averne frequentata una per decenni. Mia madre era per me una incognita; beveva l'essenziale, non fumava, non dormiva, mangiava poco, non si ammalava, era sempre in energico movimento. Passati i novanta anni di età - grondante di sudore, dopo avere trascorso, giusto per passare il tempo, un paio di ore a stirare nel mezzogiorno della calura agostana riminese - qualche volta l'ho sentita pronunciare la frase: "andrò a coricarmi perchè mi sento un po' stanca". Quando lei entrava in una stanza io immaginavo che virus e batteri sarebbero fuggiti terrorizzati per cercare di evitare quello che di lì a poco sarebbe potuto succedere. Lei era impermeabile a qualsivoglia ideologia o argomentazione che non si traducesse in immediata modalità operativa. Quale (apparente) paradosso, per lei era anche normale individuare e ribaltare immediatamente i punti chiave in merito a qualsiasi argomento. Anche se non lo dava a vedere, era una persona sostanzialmente avversa a qualsivoglia autorità imposta. Ricordo bene che le uniche tesi che non aggrediva erano quelle che trattavano la musica blues, il jazz, il rock - forse perchè intuiva che tali approcci fossero per sè stessi fondamentalmente auto-ribaltanti - e la chimica che, anche quando poteva contenere aspetti meramente speculativi, fantasmatici, lei avrebbe potuto comunque scorgere qualche indispensabile componente operativa osservazionale- sperimentale. 

Per questa sua unicità, dall'età di dieci anni fino ai quindici, ho avuto il sospetto che lei potesse essere il prodotto di qualche ignoto esperimento alieno. 

A distanza di decenni penso che mia madre, sebbene da bambina le avessero imposto di conseguire la sola istruzione elementare - come peraltro molte della sua generazione, sarebbe stata (terrestre o aliena) un valido 'naturale' co-addestratore nel team di una scuola Shaolin.

# tech: The U.S. Navy's patent for a "terrestrial UFO" (titled 'unconventional spacecraft propulsion systems')

<< A craft using an inertial mass reduction device comprises of an inner resonant cavity wall, an outer resonant cavity, and microwave emitters. The electrically charged outer resonant cavity wall and the electrically insulated inner resonant cavity wall form a resonant cavity. The microwave emitters create high frequency electromagnetic waves throughout the resonant cavity causing the resonant cavity to vibrate in an accelerated mode and create a local polarized vacuum outside the outer resonant cavity wall.
