200 Highly Advanced Alien Civilizations Hidden In Our Galaxy

The founder of modern SETI, Frank Drake, claimed that at least 200 highly evolved cultures are hidden somewhere in our galaxy.
Estimates of the number vary from 10 thousand to a million. It is a tough figure. No transmissions from space have been observed in the last 30 years. Yes, that is not contrary to conservative scientific dogmas.
The world’s largest computer network links to SETI (Search for Extraterrestrial Intelligence). SETI@home will allow you to process data generated by the world’s largest radio telescope located in Arecibo, Puerto Rico.
The telescope detects signals from the entire galaxy, but does not study them. More than one million PCs participate in the initiative.
Telescopes pointed at stars to look for signs of existence in the constellations of Tau, Eridan and a spherical mass, No13. So far, the search for an intelligent existence has ended in disappointment.
NASA Cyclops mission worth $10 billion. Thousands of telescopes are located at distances of 15 kilometers. The telescope is tuned to transmit signals between 1,000 and 1,300 light-years.
They also constantly tried to attract publicity by sending different signals and artifacts into deep space. The first transmission transmitted from space sent back details about Earth coordinates, simple physical constants, DNA code, Bach songs, and images of the Egyptian pyramids. No response yet.
Why is the room silent?
It’s too early to start complaining about radio waves from Earth hitting the nearest stars. The world is actually older than that. The time would focus on the improvements made by microelectronics and radio telescope technologies.
It is theorized that every technological society would ruin itself.
The zoo hypothesis states that aliens are watching us. The connection between them and us is limited due to the requirements of the experiment.
The tale suggests that our “brothers” consider our innocence to be rightly good, so it is difficult to tell us that a contact has been formed. The latest study by Canadian scientists indicates that the Earth is much younger than the planets of other solar systems.
Josef Schklovsky was one of the most active defenders of extraterrestrial cultures. However, towards the end of his term, he changed his mind and came to a tragic conclusion. Most doctors are wary of electronic cigarettes.
Peter Word and Donald Brownley feel that the Earth and the planetary system can satisfy a variety of rigorous criteria to be suitable for existence and knowledge.
The criteria for a planet are extremely difficult to satisfy: the planet must be located in a solar system; it must even be in an orbital path of massive gaseous planets, the star must have an appropriate shape (in a non-dwarf galaxy), the planet must be located in a warm area of the star, and it could also have a wide natural satellite.
Some progress is being made in the fields of exoplanet detection and intelligent life detection. A find is likely within 20 years, given that intelligent life resides somewhere.
The search could prove useful in discovering large natural satellites of Jupiter. The evidence indicates that Mars has large deposits of ice and ancient water. Mars has no atmosphere. The diameter of Europe is 4 times smaller than that of the Planet. Galileo found the satellite in 1610.
Galileo was a probe of Europe, collecting valuable details. The satellite is 50 km below the ocean, covered by a dense layer of ice. The other two places with significant amounts of water could be Planet and Europa. It also provides an oxygen-rich atmosphere. Scientists also need to establish when Earth’s oxygen originated in the biosphere.
