The astrophysicist did not consider it shameful to search for signals from other worlds.
Nikolai Kardashev, academician of the Russian Academy of Sciences, director of the Astro Space Center of the Lebedev Physical Institute, died on Saturday, August 3, 2019. Scientists who are looking for brothers in mind will remember him with a kind word for a very, very long time and refer to his famous scale - the "Kardashev scale", having caught some strange signals from the depths of the Universe.
Nikolai Semenovich believed that representatives of extraterrestrial civilizations could well signal us. He even figured out who exactly is able to get in touch.
Nikolai Kardashev classified highly evolved aliens back in the 60s of the last century, when mankind first aimed radio telescopes in the hope of picking up signals from brothers in mind. In the basis of the classification, which is still in use, the scientist put the level of energy consumption by a particular civilization.
According to Kardashev, type I civilizations are those that fully use the resources of their planet - all possible sources of energy. By the way, we do not yet reach them. Our level is just above zero. After all, humanity uses only a tiny part of the energy resources of its planet. And he has not yet mastered, for example, thermonuclear sources.
Type II civilizations have the energy of local luminaries at their disposal, which makes them 10 billion times more powerful than Type I civilizations.
Type III civilizations are omnipotent. They found ways to tap the resources of an entire galaxy, including the energy of black holes. This makes them 10 billion times more powerful than Type II civilizations and allows them to colonize neighboring star systems.
Kardashev assured: mankind is capable of reaching both II and III levels sooner or later, like any other civilization, whose energy consumption is growing by at least one or two percent a year. As, by the way, on Earth.

The transition to the next stage of development, according to the scientist, takes from several thousand years to several tens of thousands. On the scale of the Universe - just a moment.
The academician's ideas look fantastic, but seem to be confirmed. The fact that civilizations of a "higher order" do exist, perhaps, is evidenced by the so-called fast radio bursts (FRB) - incredibly powerful signals coming from some mysterious sources of radio emission, distant from the solar system by billions of light years old.
Mysterious signals were revealed by Kardashev's colleagues - astronomers working on the Search for Extraterrestrial Intelligence (SETI) program. It was revealed, which is very symbolic, with the help of artificial intelligence (AI) - artificial intelligence (AI), which recognized the "intelligent beginning" among 400 terabytes of accumulated information. This information itself was data obtained from the Green Bank Telescope radio telescope.
Colleagues assured, according to Kardashev, to provide energy to "transmitters" generating pulses of FRB of colossal power, could easily be a type III civilization.
Nikolai Kardashev was in charge of the international project "Radioastron". And then he thought unconventionally. I thought that with the help of the space radio telescope of the same name installed on the Spektr-R satellite, it would be possible to find "wormholes." Or wormholes, as such passages in the fabric of space-time are also called, connecting different points of the Universe, including very distant from each other. Through these holes we could get to the brothers in mind. Or they are up to us. After all, the academician did not rule out that one of the wormholes could be near the Earth.
Unfortunately, the telescope broke down at the beginning of this year. And now his "father" has passed away …
