The world's first 'artificial black hole'

The latest issue of Digital Science magazine, the world's first "artificial black hole" was born in a laboratory in Southeastern China.

The magazine said that despite its mini-size, the ' artificial black hole ' has not been created nor does it allow any form of matter to escape its gravitational attraction, including sunlight. However, unlike black holes in the universe where people are always worried about a threat of destruction, we can now completely put these ' black holes' in our bags.


Cui Tiequn and Cheng Qiang , of the Southeastern University of China, the two leaders of the research program said: ' In fact, the black hole we created is not entirely a black hole in the strict sense of the word. this '. According to Professor Cheng Qiang, they use a simulation device to create ' artificial black holes '.

Currently, this device only absorbs electromagnetic waves. However, Cheng Qiang believes that in the future it can absorb light. And in addition to electromagnetic waves, this ' artificial black hole' cannot absorb any matter.

According to Mr. Cheng Qiang, the 'artificial black hole ' they create is not only the dangerous ' black hole ' as it is known. Conversely, in the future it can help people better absorb solar energy.

Since the beginning of this year, two American scientists, Evgenii Narimanov and Alexander Kildishev, have published theoretical arguments and design schemes to create a ' mini black hole' . The solution they created was to create an " artificial black hole " that simulates some of the properties of a black hole, capable of drawing radioactive material near it and moving into the center of the " black hole ". spiral.

However, when both Evgenii and Alexander, two Purdue University scientists have not yet realized their ideas, an 'artificial black hole ' was born in China.

In fact, the artificial black hole created by two Chinese scientists compared to the real black hole in the universe is very different. This is not only in size but the principle of existence of these two black holes is completely different.

The black hole in the universe can ' swallow ' all matter, including light, by its enormous material density. Meanwhile, the "artificial black hole " is a device that simulates the nature of light waves when sucked into a black hole. This device causes the light wave to approach to be bent and sucked into the center.

This means that even though both types of black holes produce the same result for the light waves that appear around them, the reception of light is completely different.
