Life May Exist Within A Super Massive Black Hole Despite being considered the most destructive force in space and absolutely uninhabitable, the conditions for life exist inside supermassive black holes, a Russian cosmologist has theorised. Going out on a scientific limb somewhat, Vyacheslav Dokuchaev has even suggested that if life did exist inside the SBH, it would have evolved to become the most advanced civilisation in the galaxy. Supermassive black holes are such powerful gravitational forces that they suck in everything around them, including light, and nothing that crosses the black hole’s ‘event horizon’ is ever seen again. But now Dokuchaev, of Moscow’s Institute for Nuclear Research of the Russian Academy of Sciences, says existing evidence combined with new research throws up intriguing possibilities for certain types of black holes. Inside a charged, rotating black hole there are regions where photons can survive in stable periodic orbits. Dokuchaev specialises in studying those orbits and their dynamics. He speculates, in a paper published in Cornell University’s online journal arXiv, that if there are stable orbits for photons, there is no reason why there could not be stable orbits for larger objects, such as planets. The problem is that these stable orbits would only exist once you have crossed the threshold of the event horizon, where time and space flow into one another. The event horizon, at the lip of the black hole, is known as the point of no return. However, beyond the event horizon is another domain, known as the Cauchy horizon, where time and space return to stable states. It is inside the Cauchy horizon that life could exist, Dokuchaev argues in a paper published in Cornell University’s online journal arXiv, However, the type of life that could exist in those conditions - where they would be subject to massive fluctuating tidal forces - would have evolved beyond ours. The life that could exist there would likely be a civilisation ranked as Type III on the Kardashev Scale. There are three levels to the scale with one being the lowest and three the highest. Humanity is still looking to attain Level 1 status; mastery of its own planet. ‘Interiors of the supermassive black holes may be inhabited by advanced civilisations… invisible from the outside,’ he says. Though that is a spine-tingling thought, Dokuchaev’s proposition can only ever remain theoretical. Because nothing can ever escape from a black hole due to its enormous gravitational pull, we will never know if it is true.

Crne rupe skrivaju civilizacije? Nakon teorije da su izvanzemaljce možda progutale crne rupe, pojavila se nova, još intrigantnija Vyacheslav Dokuchaev, znanstvenik s Moskovskog instituta za nuklearna istraživanja, predložio je ovu senzacionalnu hipotezu. Navodi da bi tzv. crne rupe mogle sadržavati ne samo različite mikročestice materije, nego i cijele planete s živim organizmima. Dokuchaev sugerira kako takve planete rotiraju unutar crnih rupa, te imaju stabilne orbite. Prema prihvaćenim pretpostavkama, sve što dospije unutar crne rupe apsorbira se i nestaje. No je li doista tako? Čini se da sve donedavno, čak ni znanstvenici nisu imali jasnu ideju što se točno događa unutar dubina crnih rupa. Proračuni koje je napravio Dokuchaev pokazali su da pod određenim uvjetima objekt poput rotirajuće crne rupe može imati vrlo kompleksnu unutrašnju strukturu, unutar koje se sitne čestice, fotoni i protoni, kao i cijela makroskopska tijela, pa čak i planeti mogu rotirati oko središta singularnosti. Singularnost je središnje područje crne rupe, točka gdje koordinate vremena i prostora postaju beskonačne. Kako to izgleda u praksi? Npr. ako slučajni promatrač upadne u zonu privlačnosti crne rupe, prvo prolazi horizont događaja. Astrofizičari ovako nazivaju imaginarnu granicu prostora i vremena koja razdvaja događaje s obzirom na točku beskonačnosti. Ovo ima veze s pretpostavkom da niti jedna informacija ne može putovati brže od svjetlosti. Sve što prijeđe horizont događaja više ne može napustiti crnu rupu. Teoretski, promatrač koji prijeđe horizont događaja prestaje postojati neko vrijeme, no onda može dospjeti unutar vrlo čudnog mjesta gdje dimenzije svemira imaju odlike vremena. Moguće je da promatrač dođe do stabilne orbite (ovo naravno nije orbita u doslovnom smislu riječi, ali ima neke sličnosti s uobičajenim planetarnim orbitama). Postojanje takvih orbita predložili su već ranije istraživači, i to za one tipove supermasivnih crnih rupa koje, osim vanjskog horizonta događaja, imaju i unutrašnji tzv. Cauchy horizont, nakon kojeg vrijeme i postor uzimaju svoja uobičajena svojstva. Ipak, ovaj fenomen nije detaljno proučavan. Kako navodi Dokuchaev, takve orbite nalaze se izvan ekvatorske ravnine rotirajuće crne rupe, i zbog toga njihova ogromna gravitacija više ne utječe na te objekte. Objekti koji se nalaze tamo, okreću se oko singularnosti, baš kao što se i planete okreću oko središnje zvijezde. No za razliku od uobičajenih orbita, ove nisu kružne, već imaju kompliciraniju putanju koja podsjeća na vijenac. Planet koji rotira takvom orbitom primat će energiju i od singularnosti i od fotona zarobljenih unutar crne rupe.
