NASA may have decided that Oumuamua, the first interstellar object ever spotted in our system, is a "metallic or rocky object" of a length of about 400 meters (1,312 feet) and from a width of 40 meters (131 feet), but a new study from the Harvard Smithsonian The Center for Astrophysics says it could be something much more exciting – it could be "an original veil of light artificial "sent by another civilization.
The study, which was posted online earlier this month, suggests that Oumuamua's "strange" "excessive acceleration" could be artificial in nature, as it was implied that ## 147 ## # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # 39, it was not an active comet.
"Considering an artificial origin, a possibility is that" Oumuamua is a veil of light, floating in interstellar space as a debris of advanced technological equipment, "wrote researchers.
COMETS AND ASTEROIDS MAY LIVE LIFE ALL ABOUT GALAXY, STUDY FIND
The document goes on to say: "Our similarly sized light sails have been designed and built by our own civilization, including the IKAROS project and the Starshot Initiative, and the light curtain technology could be used on a large scale for the transport of cargo between ships. planets or stars. "
They even theorized that "Oumuamua" could be a fully operational probe, intentionally sent near the Earth by an extraterrestrial civilization ", although this scenario was called" exotic ".
The paper was written by postdoctoral researcher Shmuel Bialy and Professor Abraham Loeb, director of the Institute of Theory and Computation of the CfA.
Other studies have suggested that other "Oumuamua-type objects" could potentially enter our solar system, with some of them potentially carrying lives.
"The likelihood of galactic panspermia strongly depends on the lifetime of the putative organisms as well as the speed of the transporter", according to an article published in The astronomical journal by Manasvi Lingam and Loeb supra.
They add: "Velocities between 10 and 100 km s-1 give the highest probabilities, however, since the lifetime is quite long, even hypervelocity objects moving at more than 1000 km s-1 have an important chance of being captured, thus increasing the likelihood of panspermia "
THE INTERSTELLAR VISITOR & OUMUAMUA & # 39; SHOULD NEVER HAVE LEFT AT HOME, SAYS THEORY
According to an article published on the NASA website, panspermia is the hypothesis that life on Earth originates from the microorganisms of outer space inadvertently carried here by objects such as space, meteorites and asteroids.
Oumuamua, the Hawaiian name for "pathfinder" or "scout," was discovered in October 2017 by the PanSTARRS1 telescope after spotting a new point of light coming from a strange direction at an unusually fast speed.
Since its discovery, the researchers have wondered whether it was a comet or an asteroid, even though it was finally determined that it was safe. 39, acted of a comet.
Oumuamua moves away from the Sun at a speed of about 70,000 mph, to the outside of the solar system. In about four years, it will pass the orbit of Neptune to reach the interstellar space.
