Greetings to all readers. Welcome to a cozy corner of the absurd.
UFO, UFO. Everyone knows about aliens and flying saucers, but everyone has a different attitude towards these objects. Most of humanity that believes in aliens is confident that aliens are ahead of us in development. But how much? Let's think: "What engines are installed in flying saucers?" Maybe not so far behind the technology of aliens?
What do we know about UFOs?
Not as much as we would like. We do not know their purpose, where they came from, and what the pilots are. We can't even 100% say: "Are their ships manned?" All we have is eyewitness accounts.
Let's stop at speed. Researchers at the University of Edinburgh were able to calculate the estimated speed of the plates. It is about 30 thousand km / h. or 8.3 km / s. This is just above the first cosmic speed. Such speeds have long since obeyed us. Another thing is that terrestrial rockets that reach such indicators are huge and consist mainly of fuel, and this is not observed in flying saucers. Also, our ships cannot levitate. So the alien ships do not work with liquid fuel, like our rockets. But we have guesses.
If the second type exists only on paper, then the first engine has already been created. The RD-0410 engine was designed and created in the USSR in the period from 1965-1985. Its mass was only 2 tons, and the specific impulse was 900 seconds, which is 3 times higher than that of the Proton launch vehicle. Hypothetically, alien ships could have a similar setup.

Antimatter engine is an excellent prospect for space travel. However, we have problems with this, how to get enough antimatter, and most importantly, how to store it.
What else can be installed in alien ships?
Eminent scientists have taken on the development of magnetic motors at all times, but no significant progress has been achieved. It is unlikely that they are installed in alien ships. Magnets do not carry any energy in them. Even if we assume that the UFO levitates in the sky due to the Earth's magnetic field and the magnetic engine, then in open space this will become impossible. And not all celestial bodies have a magnetic field.
The anti-gravity engine is a completely dark forest. Even if we assume that the aliens have a device of this type, then it should work in tandem with another motor, which ensures movement on Earth at a speed of up to 30 thousand km / h. The anti-gravity engine would only allow the aliens to take off and land.
To summarize, the most obvious candidate for a UFO motor is a nuclear powered or antimatter motor. Many would argue that UFOs have wormhole installations. Perhaps, but such technologies are required for space travel. Now the analysis was how they move on Earth.
It is impossible to say that we are hopelessly behind alien civilizations. Most likely the most technologically advanced aliens appeared earlier than humanity. And now we are separated by no more than a thousand years. I can give you an example - shipbuilding. A thousand years ago, ships were propelled by oars, and now by engines. If we compare us and aliens, then we still move in space on oars, but it's only a matter of time.
