Scientists suggest mysterious “Oumuamua” object is an alien spacecraft, possibly a probe sent by extraterrestrials.

Earth’s technology, in terms of solar-powered lightsails, is still at the beginning. We plan to send a fleet of tiny laser-powered light sail craft, Breakthrough Starshot, of the Breakthrough Listen initiative.

Is technology of other planets with extraterrestrial life-forms more advanced?

Scientists have been buzzing over “Oumuamua” ever since the mysterious space object was observed rolling past the sun in late 2017. “Oumuamua,” a Hawaiian term that means “a messenger from afar arriving first.”

The late Stephen Hawking led a team back when it was first observed to further investigate this. He believed it was the alien mothership.

Hawking and his team said, “Researchers working on long-distance space transportation have previously suggested that a cigar or needle shape is the most likely architecture for an interstellar spacecraft, since this would minimize friction and damage from interstellar gas and dust.”

Harvard researchers have now come forward to say that it had clearly come from outside of our solar system.

Oumuamua is fast, massive (the size of NYC Empire State Building), reddish in color, and spins with an unusual trajectory.

The most curious part is that it’s flattened and elongated. They also note, the way it has “accelerated on its way through the solar system set it apart from conventional asteroids and comets.”

The researchers are raising the possibility that Oumuamua is an alien spacecraft. In The Astrophysical Journal Letters, the object "may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization."

“Alternatively, a more exotic scenario is that Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization,” two Harvard researchers noted.

While the researchers are suggesting that aliens sent Oumuamua, they aren't claiming outright that aliens sent it. But after a careful mathematical analysis of the way the interstellar object sped up as it shot past the sun, they say “Oumuamua” could be a spacecraft pushed through space by light falling on its surface. The paper calls it a "lightsail of artificial origin."

It is impossible to guess the intention of Oumuamua without more information and data.

Avi Loeb, chairman of Harvard's astronomy department and a co-author of the paper, said if Oumuamua is a lightsail, one possibility is that it was floating in interstellar space when our solar system ran into it, "like a ship bumping into a buoy on the surface of the ocean."

Loeb and his collaborator, Shmuel Bialy, of Harvard-Smithsonian Center for Astrophysics, acknowledge that the alien spacecraft scenario is an "exotic" one.

Some other space scientists have strong doubts about it.

"It's certainly ingenious to show that an object the size of Oumuamua might be sent by aliens to another star system with nothing but a solar sail for power," Seth Shostak, a senior astronomer at the SETI Institute in Mountain View, California.

Coryn Bailer-Jones, an astronomer at the Max Planck Institute for Astronomy in Heidelberg, Germany, voiced similar objections. "In science," he said in an email, "we must ask ourselves, "Where is the evidence?, not "Where is the lack of evidence so that I can fit in any hypothesis that I like?"

But maybe we just haven’t had the opportunity, or means, to gather the necessary evidence.

Bailer-Jones, who earlier this year led a group of scientists who identified four dwarf stars as likely origin points for Oumuamua, raised further questions. The scientists were particularly fascinated by the object's tumbling motion.

Many had followed Bailer-Jones lead, but Loeb called the hypothesis "purely scientific and evidence-based," adding, "I follow the maxim of Sherlock Holmes: when you have excluded the impossible, whatever remains, however improbable, must be the truth."

The truth may be hard to establish, As Oumuamua has left the solar system and is no longer visible even with telescopes, the truth will be hard to confidently conclude.

Loeb called for a survey of lightsails as extraterrestrial civilizations “in the solar system is warranted. Irrespective of whether Oumuamua is one of them."

Loeb said, “The fact that we've observed one interstellar object like Oumuama suggests that others may be out there — and astronomers should begin a search for them.”

Alien conspiracies point to that we are closer to this “truth” than NASA and the government will admit.

Luckily, we have scientists like Loeb on our side.

Oumuamua is spinning on its axis every seven hours and is expected to zoom past Jupiter next year, before Pluto in the 2020s.

One thing is for sure, as far as the public knows, the most fundamental question in science is still not answered. Are we alone?
