Because most of it lurks in the microwave region of the electromagnetic spectrum, the CMB is invisible to us because microwaves are far past the realm of visible light since they are too long for the human eye to process. ![]() It is also the most powerful radiation source in the entire universe. The cosmic microwave background (CMB) is made up of the remnants of electromagnetic radiation from the Big Bang. That still doesn’t answer the question of how life could survive there if any extraterrestrial life-forms had (hypothetically, again) appeared in the movie. The planet’s precarious orbit and zooming around close to the speed of light kept it safe from Gargantua’s gaping maw. Gargantua was immense and rotated extremely fast, with Miller’s planet orbiting just about as close to the event horizon it could get without being shredded by intense gravitational forces and lost to time and space (though some scientists would disagree about that). ![]() Remember when the crew of the Endurance in Interstellar touched down on an exoplanet dangerously close to the supermassive black hole Gargantua? The movie had inspired a related study Bakala was involved in. “The basic condition for the existence of imaginable biological forms is a sufficient supply of energy, and therefore a reasonable surface temperature of the exoplanet,” Bakala and his team said in a study recently published in The Astrophysical Journal. If this is a supermassive black hole of the right size, a planet could somehow host life that survives even on the fringe of extreme cosmic hostility. ![]() Never mind that the event horizon is the point of no return. Physicist Pavel Bakala, of the Hlohovec Observatory and Planetarium in the Czech Republic, and colleagues have figured out a way that life could flourish on an exoplanet orbiting just on the edge of a black hole’s event horizon. An exoplanet orbiting a supermassive black hole is probably one of the most inhospitable places for life that you could possibly think of.Īssuming the planet doesn't fall in, who - or what - could survive in such a place? There is possibly a (hypothetical) exception.
