Leading Astronomers: Oumuamua Is ‘Alien Probe With Broken Engines,’ Could Have Hostile Intentions

A leading astronomer studying the origins of the space object known as Oumuamua has come out declaring it’s an alien probe with broken engines.  Dr. Jason Wright claims that Oumuamua’s movement is that of a craft that has lost power to its engines.


Right now, leading scientists are studying the odd “cigar-shaped” object which originated outside of our solar system.  Teams lead by renowned physicist, Stephen Hawking, are attempting to discover whether or not Oumuamua is alien or natural. If a radio signal is detected later today, scientists will “proceed with caution.”


Professor Avi Loeb, Professor of Astronomy at Harvard University, sais: “My recommendation, as in any dialogue, is that we first listen and do our best to understand what we are hearing. Once we figure this out, we can decide how to respond,” he said.  “Overall, I am an optimist. I believe that a very intelligent civilization will be peaceful, and we could save ourselves millions or billions of years by learning from it. But there is also the possibility that such a civilization will have hostile intentions and risk our existence, so we should deliberate carefully in any future contact with them.”


According to the Daily Mail, Dr. Wright from Penn State University is already declaring it a spacecraft.  Oumuamua is about a quarter of a mile long, 260 feet wide, and currently traveling at 196,000 mph. Rather than moving through space like other natural space rocks, astronomers believe that it is “tumbling” through our solar system.

‘”Such derelict craft would, if they are not traveling so fast that they escape the Galaxy, eventually ‘thermalize’ with the stars and end up drifting around like any other interstellar comet or asteroid,” Dr. Wright wrote in his blog. “In fact, since they (presumably) no longer have altitude control, one would expect that they would eventually begin to tumble, and if they are very rigid that tumbling might distinguish them from ordinary interstellar asteroids… and in fact, just because their propulsion is broken doesn’t mean that their radio transmitters would be broken.”


Wright suggests that the object could be a “Von Neumann probe,”  a theoretical self-replicating spacecraft that visits star systems. “Such a discovery would imply that there are lots of these things in the solar system at any given moment (even if they are deliberately targeting the sun, they are hard to spot and we’ll miss most of them), and so lots of opportunities to study them,” Wright assessed.  Wright also previously suggested the mysterious dimming of star KIC 8462852  (also known as Tabby’s Star) could be caused by an alien megastructure called a Dyson Sphere (a hypothetical structure which encompasses a star and uses harnesses its energy.)


Wright’s assessment comments come ahead of a project later today in which scientists will use high-tech scanners to discover if Oumuamua was sent by an alien civilization.


Another oddity is that Oumuamua is flying very ‘cleanly’, without emitting the usual cloud of space dust that astronomers observe around asteroids. Scientists say this suggests that the object could be composed of metal, rather than rock.

Stephen Hawking: ‘Earth Will Become A Flaming Ball Of Fire By 2600’

Physicist and professor Stephen Hawking is warning that earth will become a flaming ball of fire by the year 2600. He also warns that if humans want to avoid permanent extinction, we should be making plans to evacuate the earth.


Hawking claims that mankind will destroy the earth making it a fireball within the next 600 years. The renowned physicist believes soaring population sizes and consequential increasing demands for energy and food will lead to the catastrophe. Hawking also says that humanity should begin looking to the stars to avoid this fate, with our nearest neighbor Alpha Centauri the best candidate for our escape. Hawking also urged financial backers to put funds behind a project that would send probes to the star system.


The Alpha Centauri system is the closest star system to our sun and consists of three stars. Of those three stars, Proxima is the closest to our sun. At a mere 4.367 light years away, on our sky’s dome, we see this multiple star system as a single star – the third-brightest star visible from Earth. And it’s this system that Hawking has his eye on.

Hawking made the comments while speaking via video link at the Tencent Web Summit, held in Beijing. The British cosmologist, who was diagnosed with motor neuron disease at age 21, is backing the Breakthrough Starshot project. That project will likely see a probe sent to Alpha Centauri in the very near future; 20 years or so.


“The idea behind this innovation is to have the nano craft on the light beam. Such a system could reach Mars in less than an hour, or reach Pluto in days, pass Voyager in under a week and reach Alpha Centauri in just over 20 years,” Hawking said praising the Breakthrough Starshot project. Astronomers feel that there is a reasonable chance that an Earth-like planet exists in one of the habitable zones within the star system too.


Right now, the fastest spacecraft would take 30,000 years to reach Alpha Centauri. But Hawking also threw another doomsday prediction on the table.  At the 2017 Web Summit, held in Lisbon and attended by around 60,000 people, he warns that AI (artificial intelligence) is on the verge of replacing people. According to Hawking, humanity must be prepared to tackle artificial intelligence to stop robots replacing people. Hawking said the technology could transform every aspect of life in some good ways, but cautioned that intelligent machines pose new challenges. He said robots are already threatening millions of jobs but that this new revolution could be used to help society and for the good of the world, including alleviating poverty and disease.


“The rise of AI could be the worst or the best thing that has happened for humanity,” Hawking said via video link at the opening night of the summit on Monday. “We simply need to be aware of the dangers, identify them, employ the best possible practice and management and prepare for its consequences well in advance.”
