Neutrino
This tiny particle moves at the speed of light, has a weak interaction, exists in the field of String Theory and, as a result, can serve as a mirror of a known neutrino source or interfere with it. Each person has their own neutrino background. So, if someone were watching a person from the far side of the Moon, they would be able to do this in real time absolutely unnoticed by the person himself, and from Proxima Centauri or Alpha Centauri they would need a period of time of more than four years for these purposes. If you notice patterns in real time with the far side of the Moon or over a period of more than four years, be sure to report it. We cannot remain silent about this.
Everything on earth has its own unique neutrino background and, as a result, for humans it can serve as medical support; each speck of dust has its own neutrino background, which is important for positioning systems in space for drones, robots, autopilots, and humanoid androids.
As an ordinary person, I am more interested in neutrinos from the point of view of organizing communications and positioning in space as the closest area of application in human life and potentially as the fastest-growing concept of investing in neutrinos, but I do not argue that there are other more expensive aspects of using neutrinos from an investment point of view. With the use of neutrino-based communication, the usual barriers of known radio and laser types of communication are lost. Mirroring, interference and quantum technologies make this type of communication almost impossible to hack. Agree, shouting into the radio wave of your phone or WI-FI router to the entire known area is, in principle, not the best idea even if there are several encryptions, although many people probably don’t even realize this.
