How could the extraterrestrials have visited Earth in the past?Michio Kaku: “The military must demonstrate that we have not been visited by aliens: there are videos,”Have you finally found the astronomers a Dyson sphere?

The group more recently discovered rocky bodies close to the Earth is a particular type of the so-called “objects coorbitales” . This is the “cuasisatélites”, a series of rocks in space that trace, as does the Moon, orbits are stable around our planet and that will accompany us on our journey around the Sun. By now, you know nine cuasisatélites of the Earth , but your number could be much higher.

According to an article recently published in The Astronomical Journal by the researcher James Benford, these small bodies, dark, and difficult to study, prove to be particularly suitable for intelligent extraterrestrials who want to have guarded the Earth . And the ideal place to locate probes “spy” , which could be installed there, watching us, from time immemorial.

given the fact that the cuasisatélites are very close to our planet once a year, at distances much smaller than any other thing that is not the Moon itself. In fact, they have the same orbital period than the Earth and provide an ideal way of observing our world from a natural object, close and safe. In addition, according to Benford, this kind of coorbitales provides a series of resources that could be very useful for the spies aliens: materials, energy, solar constant, a firm footing and, above all, an ideal place to stay hidden.

sniffers

Until now, the cuasisatélites have been poorly studied by astronomers, and no program of SETI, the organisation that seeks to civilizations smart in the space, has been busy never of them. For that reason, Benford proposes to carry out a series of observations of these objects to find out if there was any probe alien. And warns that those probes could also be very ancient, even before the existence of man.

Benford calls these hypothetical devices “lurkers” (peeping toms or prying eyes). A lurker, therefore, is a viewing tube hidden, unknown and has managed to pass completely unnoticed. It is possible that behind it are hidden, or not, dark intentions, as are the motivations of the builders. And almost certainly, the lurkers will be robotic, as are our own probes of exploration, from the Voyager to New Horizons.

These spy robotic, says Benford, could have been sent to observe the Earth a long time ago , and it is even possible that some of them have already exhausted their source of energy, which implies that to find them would be to do authentic “archaeology extraterrestere” . According to the researcher, if after you have registered the cuasisatélites not found anything, that I would like to say that no one has come never to observe the life of the Earth, and this despite the fact that that life would be evident (due to the characteristics spectral lines of our atmosphere) to any observer interstellar explore our region of sky during the past billion years.

objective

The cuasisatélites, writes Benford, the objects are very attractive for the search of SETI because of its proximity. The researcher is convinced that we should investigate these bodies as soon as possible, both in the electromagnetic spectrum of the microwave and the light, as in the radar. We could even visit them with probes. Among them, the most promising would be 2016 HO3, which is the cuasisatélite of the Earth, the more small, stable, and close known until now. For now, only China has announced its intention of sending a probe up there.
