Introduction

In Christopher Nolan’s 2014 sci-fi masterpiece Interstellar, three planets (aside from Earth) captivate viewers with their extreme environments.
Surprisingly, these worlds, technically termed Blanets, may not be purely fictional and could exist in reality.

What are Blanets?

Formation Theory: In 2019, Japanese scientists proposed a theory suggesting that planets could form within massive dust and gas clouds surrounding supermassive black holes.
Unique Characteristics: Blanets, unlike Earth, are not expected to resemble habitable worlds due to their formation near black holes.
Surrounding Environment: Black holes are encircled by colossal discs of gas and dust, influenced by the black hole’s gravitational pull and heating effects.
Galactic Presence: Nearly every galaxy is believed to harbor a supermassive black hole at its center, acting as a gravitational nucleus around which stars organize.

Similar Mechanism: Planets near young stars form from the collision and aggregation of dust and gas particles in swirling disks. A comparable process could occur near supermassive black holes.
Blanet Characteristics: Blanets are anticipated to be approximately 3,000 times larger than Earth and must orbit the black hole at a distance of about 100 trillion km to avoid gravitational disruption during their formation.

Extreme Environments: Blanets represent worlds of extremes, vastly different from habitable planets like Earth.
Scientific Inquiry: The study of blanets offers insights into the dynamic interactions between black holes and their surrounding environments, pushing the boundaries of astrophysical understanding.
