Surprising data leaked from NASA. EmDrive works?
We heard about a drive that would revolutionize space flight back in 2000, but most researchers didn’t take the news seriously. Why? Because it defies the laws of physics. However, a recent accidental leak of data from NASA has electrified the public, because according to it, it turns out that American scientists confirm the operation of EmDrive.
The father of the project is Roger Shawyer. It is a British scientist whoóry in 2000 developed EmDrive. The drive, according to the designer, works only with electricity. No propellant is needed here, making it extremely cheap to operate. Assuming, of course, that the operation of such a motor is possible.
EmDrive and the laws of physics
The principle of operation is based on the so called. radiation pressure. In a big skróIn a cone-shaped structure, a microwave tube producing waves of a certain wavelength will create radiation pressure and thusób is about to form a string. The pressure will be created because the waves propagating towards the narrower end of the structure will slow down, and those thatówhich will propagate in the opposite direction and accelerate.

It all sounds quite nice, but scientists who are less enthusiastic about the project point out that it violates one of the basic principles of physics, i.e. conservation of momentumóra móThis will cause the vector sum of momentumóin all theóin an isolated system remains constant. So, if it turns out that such a drive works, the laws of physics will have to be verified.
A space propulsion dream
In 2009, Chinese scientists built a prototype of such a device and confirmed that it produces thrust. Similar results were obtained during an experiment by scientist Giudo Fett, whoóry through his company Cannae Inc. launched a miniature satellite into space equipped with an EmDrive. In the meantime, tests of the device were carried out repeatedly with róThe principle of operation is based on the so-called.
The whole thing fires the imagination of people all over the world. If it turns out that such a drive does work, in króIn a short time it would change the appearance of our world. With enough power, e.g. With a two-megawatt reactor, it would take 70 days to fly to Mars. A flight to the Moon takes several hours. To the nearest star – Alpha Centauri would arrive in 92 years. It is hard to imagine what mankind could achieve with such a drive.
The whole thing will be screwedótce decided. NASA has announced a publication on the subject in December. All that’s left for us to do is wait impatiently.
