Earlier this week, Oumuamua's mysterious interstellar object again made headlines. It does not reappear because every new observation or research since passing through our solar system is back at the end of 2017, but more because new paper that is not so subtle suggests that the object actually came from aliens.
This paper, written by researchers from the Harvard Smithsonian Center for Astrophysics, talks about the behavior of objects when circling the Sun and back into space. This highlights the fact that it appeared to accelerate when it left, closing with some unclear suggestions that it might be a foreign ship or even a piece of space space junk. Not everyone in the scientific community wants to take this theory with a nominal value.
Until this point, no one really showed that cigar-shaped objects were the work of aliens. It drove through our system very quickly, and while scientists were back and forth whether it was an asteroid or comet, there was no evidence to support an explanation involving aliens. The new paper did not change that, but it tried to explain how the spacecraft propulsion system known as lightail might be responsible for accelerating objects.
A lightail like a boat screen, only in space. Lightail will stick to other objects and, being hit by material flowing from the star, builds speed without using any fuel. No one has actually built or tested Lightail, but that hasn't stopped researchers from suggesting that it might be a plausible explanation for increasing Oumuamua's speed when leaving the solar system.
This suggestion, and the implication that alien civilization might have used objects to monitor our system or even study the Earth closely, had attracted the anger of many people.
"The thing you have to understand is: scientists are very happy to publish strange ideas if they even have the slightest chance not to be wrong," said astrophysicist Katie Mack in a thread on Twitter. "Some of us are more conservative, of course. And that certainly varies based on the field. But in my area (astrophysics / cosmology), there is generally no loss to publish something that (a) is somehow interesting and (b) is not completely excluded, whether or not it finally becomes the correct answer. & # 39; "
He is not alone, and other scientists have burdened their own doubts about the theory. Simply put, there are no real smoking weapons that shout "aliens!" But there is not much evidence to prove it not. The result is a theory that sounds innovative and extraordinary, but is almost certainly nothing more than a dream.
