Can UFOs scientifically exist?

The image of UFOs is often found in science fiction. But what about reality? What are the chances of people

Probably the first thing that comes to your mind whenyou will be asked to think of an alien spaceship, a flying saucer. This image persists until Jordan Peele's new film Nope ("No"). But how does this match reality?

According to astronomer Colin Stewart, attempts have already been made to create ships that look like flying saucers. So, in the 1950s, the VZ-9 Avrocar was created.

According to the documents, the engineers tried to achievevertical landing and vertical takeoff of the ship using jet engines located along the edge of the disk. Also, experts believed that their device as a whole could reach speeds of up to Mach 3-4 (about 4-5 thousand km / h), climb to a height of up to 30.5 km and have a maximum flight range of about 1900 km. But in reality, the experts were unable to raise the ship higher than a few feet, and its speed was no more than 56 km / h. The central jet engine made the ship loud and exposed the pilot to high temperatures.

Then in 2008 there was information abouta small drone that looks like a saucer. This device will be able to cover the ship with electrodes that can ionize the air to create plasma. Further, the plasma will be accelerated due to the magnetic field and, as a result, lift will be created. According to Stewart, this is the most likely way to launch a device resembling a flying saucer.

If we talk about whether aliens penetratedalready into the Earth's atmosphere and whether they can do it at all, the astronomer is skeptical. Stewart believes that the aliens, most likely, will not be the same size as a person. This is due to the fact that their planet will still be different from the Earth. So, if gravity is stronger on their planet than on ours, then they will be lower than people, and if weaker, then higher.

But even if aliens reallycreated flying saucers, yet the chances of such travel are slim. In order to move from one star system to another, two systems are needed: the actual flying saucer and a cruiser or rocket that will deliver this saucer to the solar system.
