The event horizon of a black hole can host life. Maybe not life as we know it, but life nevertheless, so scientists should start searching for alien life there too. Movies are usually inspired by life. In different degrees, a writer uses personal life and knowledge and combines them with imagined events, characters, emotions.
No one knows exactly which part of it is lived and which is imagined. They get combined to such a degree that even the writer can get confused. And, there are also times when peoples start living the movies they see. They usually end up in a psychiatric clinic.
Science is one of the primary sources of inspiration for Sci-Fi writers. And sometimes they let their imagination get wild and make look possible even impossible scenarios. There is this particular case, where things happened the other way around: a movie inspired the vision of a scientist, and he started to study a Sci-Fi scenario and wrote scientific research.
The event horizon of a black hole can host alien life
The inspirational movie is Interstellar, and the scientist is Physicist Pavel Bakala, of the Hlohovec Observatory and Planetarium in the Czech Republic. And, he wasn’t alone. He got the help of a team to prove that the scenario is feasible. And the bigger surprise is that it is.
Pretty simple, actually. If the exoplanet finds that narrow path of the edge of a black hole horizon and orbits it, then the cosmic microwave background can provide the rest. It will generate the heat and light needed in the daytime, while the black hole shadow will take care of the cooling system nighttime provides on earth, for example.
The cosmic microwave background is the residual waste of electromagnetic radiation left all over space from the Big Bang. We can’t see it; our eyes aren’t fit for it. Just like we can’t see the black matter, so we’re used to believing things we can’t see.
But scientists say that when the unseen cosmic microwave background gets absorbed by the black hole, it gets energized. So much, as it gets close to that special place called the event horizon, that it can replace the Sun’s light and warmth. So, there’s your day! The black hole shadow casts its shadow, which can act as a cooling machine by providing the breezy effect of the night.
“The [CMB] heating regime is very similar to the regime of the planet heated by a standard star when almost all of the incoming energy can be converted to useful work and thus drive the life processes,” said Bakala.
