in New paper Posted in the magazine IscienceAstronomical physicist from the University of Vodan discusses the ability to send Nanocart to a black hole in 20-25 light years of Earth to test the nature of the built-in organism and essential physics in strong gravitational fields.
Black holes are sources of strongest gravitational fields that can be found today in the universe and are perfect laboratories for Einstein’s theory of general relativity in the strong field system. In his article, Professor Bambi explains that the possibility of a task among stars to send a small spacecraft to the nearest black hole, despite severe speculation and challenges, is not completely unrealistic.

“We do not have technology now. But in 20 or 30 years, we may be.” Professor Cosimo PambiAstronomical Physics expert and black hole expert at the University of Vodan.
“The task depends on two major challenges – finding a black hole close enough to target and develop investigations capable of taking the trip.”
As of now, the closest black hole to the ground is the Gaia BH1, which was discovered in September 2022 and is 1560 light -years.
However, we can expect that there are many unknown black holes closer to the ground.
From simple considerations, we can appreciate that the closest black hole to the ground may be at only 20-25 light years, even if this is just an approximate estimate and is affected by great doubts.
Professor Bambi said: “The previous knowledge indicates how the stars evolved that there can be a black hole that is only 20 to 25 light -years away from the ground, but finding this will not be easy.”
“Since black holes do not emit or reflect light, they are almost invisible to telescopes.”
“Instead, scientists discover and study them based on how they affect nearby stars or distort light.”
“There were new techniques to discover black holes. I think it is reasonable to expect to be able to find a nearby version over the next decade.”
Once the target is set, the next obstacle reaches there.
Traditional spacecraft, backed by chemical fuel, are very rational and slow to take the trip.
Professor Pambi refers to Nanocratt-Investigations on a gram scale consisting of a chip and light sailing-possible.
The earth -based laser will explode with photons, which accelerates the craft to a third of the speed of light.
“At this pace, the craft can reach a black hole from 20 to 25 years, about 70 years old,” he said.
“The data collected by two other contracts will take to return to the ground, making the total task period about 80 to 100 years.”
“Once the craft is approaching the black hole, researchers can conduct experiments to answer some of the most urgent questions in physics.”
“Does the black hole really have a horizon that happened, and the limits that cannot even escape the withdrawal of gravity?”
“Do the rules of physics change near a black hole?”
“Will Einstein’s theory maintain general relativity under the most extreme circumstances in the universe?”
Professor Bambi said: “The laser will cost about one trillion euros today, and the technology needed to create a nanocari has not yet.”
“But within 30 years, these costs may decrease and technology may be able to catch these bold ideas.”
“It might seem really crazy, and reasonably closer to science fiction.”
“But people said that we have never discovered gravitational waves because they are very weak. We did it – after 100 years.”
“People thought that we would never notice the shades of black holes. Now, after 50 years, we have pictures of stability.”
