A mysterious cigar-shaped object spotted tumbling through our solar system last year may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested.The object, nicknamed 'Oumuamua, meaning "a messenger that reaches out from the distant past" in Hawaiian, was first discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii.Since its discovery, scientists have been at odds to explain its unusual features and precise origins, with researchers first calling it a comet and then an asteroid, before finally deeming it the first of its kind: a new class of "interstellar objects."Now, a new paper by researchers at the Harvard Smithsonian Center for Astrophysics raises the possibility that the elongated dark-red object, which is 10 times as long as it is wide and traveling at speeds of 196,000 mph, might have an "artificial origin.""'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," they wrote in the paper, which has been submitted to the Astrophysical Journal Letters.The theory is based on the object's "excess acceleration," or its unexpected boost in speed as it traveled through and ultimately out of our solar system in January 2018."Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment," wrote the paper's authors, suggesting that the object could be propelled by solar radiation.The paper, written by Abraham Loeb, professor and chair of astronomy, and Shmuel Bialy, a postdoctoral scholar, at the Harvard Smithsonian Center for Astrophysics, points out that comparable light-sails already exist on earth."Light-sails with similar dimensions have been designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative. The light-sail technology might be abundantly used for transportation of cargos between planets or between stars."In the paper, the pair theorize that the object's high speed and its unusual trajectory could be the result of it no longer being operational."This would account for the various anomalies of 'Oumuamua, such as the unusual geometry inferred from its light-curve, its low thermal emission, suggesting high reflectivity, and its deviation from a Keplerian orbit without any sign of a cometary tail or spin-up torques."'Oumuamua is the first object ever seen in our solar system that is known to have originated elsewhere.At first, astronomers thought the rapidly moving faint light was a regular comet or an asteroid that had originated in our solar system.Comets, in particular, are known to speed-up due to a process known as "outgassing," in which the sun heats up the surface of the icy comet, releasing melted gas. But 'Oumuamua didn't have a "coma," the atmosphere and dust that surrounds comets as they melt.Multiple telescopes focused on the object for three nights to determine what it was before it moved out of sight. 3063

A top trending video on YouTube Wednesday suggested an outspoken survivor of the mass shooting at Marjory Stoneman Douglas High School is an actor.Calls by student David Hogg for stricter gun laws in the days after last week's massacre have made him the subject of smear campaigns and demonstrably false conspiracy theories."I'm not a crisis actor," Hogg told CNN's Anderson Cooper on "AC360" Tuesday. "I'm someone who had to witness this and live through this and I continue to be having to do that."  515

A revised lawsuit says the U.S. Census Bureau was able to claim it had reached 99.9% of households because census takers were pressured to falsify data in order to close cases. The amended lawsuit was filed Tuesday by a coalition of advocacy groups and local governments. It says 2020 census takers sometimes guessed the number of people living in a household or lied that residents had refused to answer questions. The lawsuit argues the disregard for accuracy was done to end the count early so the data could be processed while President Donald Trump was still in the White House, regardless of who wins next week's presidential race. 645

A passenger on board an American Airlines flight from Los Angeles to Nashville is being evaluated after reporting a serious illness.  Details were limited at this time. However, American Airlines officials confirmed that Flight 1289 landed around 5 a.m. Thursday with an ill passenger. Former Arkansas Governor Mike Huckabee was apparently on the plane and tweeted about his experience.  415

A motion filed in Superior Court says there is proof that El Cajon councilman Ben Kalasho and his wife are behind fake social media accounts used to defame a local beauty queen and restaurant. A civil lawsuit was filed earlier this year against the councilman and his wife, Jessica. It claims the woman who won in 2016, Zhala Tawfiq, was stripped of her title and not awarded the total prize money she was supposed to receive. The lawsuit claims around that time, a fake Instagram account was also created that posted the beauty queen’s face on top of other naked women’s bodies. The motion filed Monday says there is computer evidence to support the plaintiffs’ claims that the Kalashos were behind the Instagram account. The documents say “Instagram identified the IP address.” The court documents say it traced back to a close friend of Ben and Jessica Kalasho. During her deposition, Jessica Kalasho said she was with that friend the weekend the pictures were published. The Kalashos are also accused of defaming the business, 3 Brothers Taco Shop, known as the Tres Taqueria restaurant. The court documents say the Kalashos were behind a fake poll calling them the “worst Mexican food in El Cajon.” This was in retaliation for not posting Kalasho’s campaign signs on the restaurant property, according to the documents. It alleges fake Facebook profiles used to defame the restaurant “were accessed at least 194 times from the Kalasho’s El Cajon home.” Two other plaintiffs are named in the lawsuit. Attorney Lina Charry and another former beauty queen Paris Kargar, also accuse the Kalashos of defamation. It calls the behavior of the Kalashos "outrageous conduct consisting of fraud, harassment, and defamation conducted both online and in person." In a written response to Team 10, Ben Kalasho released the following statement: "The filing is comprised of untruthful allegations. IP addresses which are open to the public aren't proof. No evidence has been produced to me or my counsel to date, everything thus far has been pure allegation. Their counsel was accusing me of making the doctored up nudes when this case first started, last month he was accusing another associate of ours and now he is accusing a former queen. He is just harassing everyone at this point. This is nothing but a fishing expedition for money. It's pretty sad that we live in a society where greed and fabricated stories are normal just for 5 minutes of fame.  IP addresses on open networks don't prove anything. And, different individuals can use an IP address at different times (such as at a public library or Internet cafe or Open Networks like we had at our home).  Often, many individuals using a public or private network that use network address translation (NAT) may share a public IP address. Thus, IP addresses pose additional hurdles and are thrown out by judges. IP addresses can also be spoofed, i.e., a criminal actor can forge an IP address and thus “leave some other person’s fingerprints” or a criminal actor can relocate his illegal content from one IP address to another, or host that content from multiple IP addresses and thus leave lots of fingerprints over time. All this can be done by just parking outside my home. All the plaintiffs know where I live and work. We have footage of them parked outside my home. I have on a number of occasions offered my laptop to be searched and scanned by a forensics expert to prove I had nothing to do with any of the untruthful allegations against me, but the Plaintiffs Lawyer has chosen to ignore my offer because he knows that it will destroy his case. Their game plan is to drag this into the media for as long as possible. We look forward to trial and will not be bullied, harassed or intimidated.”  3891
