In before someone complains about it being a Forbes link.

If it wasn't aliens, that leaves only one possibility.

I read the headline quick and thought someone was talking about a secret link between these 2 films:

The two guys who co-wrote the "Theory" think the object deployed a solar sail, the same type of sail they are working on at Starshot. I'm surprised more people aren't calling them out on that. They've clearly written this to drum up interest in their own project. That's a pretty dick move on their part, especially considering how much attention this non-story is actually getting.

So is this the cover up?  This is the "It was swamp gas"?  I knew it.  Harvard tried to disclose and here comes the man!  Next thin you know, they will discredit the Easter bunny.

To be more fair to them, they're aren't many other explanations being bantered about.  I was hoping someone would at least offer something like a heat exhaust solution, similar to that used to address the pioneer anomaly.  But zilch, nada, zippo.

Quick question:  does anyone know how giant mysteriois spaxe rock's acceleration stacks up when compared to that of the pioneer anomaly?

They're=there    Stupid autocorrect

But I do mean spaxe instead of space.  The X makes it appear much edgier to millennials

It sort of bothers me that it's taken as a foregone conclusion that the object was shaped as an elongated ellipsoid. It was never imaged. The observation was just a single pixel of light, fluctuating in intensity, to which a (uniform albedo) model was applied to estimate aspect ratio and rotation characteristics. There are a lot of other degrees of freedom available to be used to achieve the same light signature.

Without even looking at the debunking article.  Calculations show that there should always be interstellar objects passing through the Solar System, many of them in fact.   Spotting them has been the problem because space is farking big.  The not-an-alien object just happened to pass unusually close to the Earth near the time which humanity could notice it and figure out it came from outside the Solar System.

With thousands of natural objects passing though year, what are the odds the the very first one would be an alien artifact? Pretty my damn small.  And the reasoning is that we can't completely explain everything about therefore aliens.  That is horrid "reasoning."  Call me when 20,539th object does something that is not a minor mystery and is different from the 20,538 objects before it.

Now lets see what Forbes has to say after I post this.

There actually are several. The primary one is actually why it was reclassified as a comet rather than an asteroid after its perihelion. Comets routinely experience acceleration away from the sun greater than 'Oumuamua did, because they release more material on the day side than night side. It never produced a visible coma or tail, but objects like Phaethon (an active asteroid believed to be an extinct comet) produce an invisible tail that is very hard to detect, and Phaethon in particular was observed quite well for some time without noticing it.

Another proposal is the pioneer anomaly. It's mostly ruled out, because it's far greater than can be easily explained, but the uncertainty in its size and albedo does leave enough wiggle room for this to work.

Has anyone explained how it is shaped different than any object ever discovered or encountered before yet?

But Isn't it worthy of note that, to date, every obeject we have observed leaving our solar system has been measured as accelerating inexplicably?   I mean there are explanations, certainly,, so inexplicably perhaps isn't the best word choice.  But those explanations are reallly only guesses, at this point.   And we can't rule out new physics.

The sample size for such objects is small. Like really small - I am only familiar with three, though their could be a couple I've missed. Scientists can test for their explanations with a carefully calibrated probe - if the acceleration is truly inexplicable, then we know new physics will be required.    I think that makes it worth a green light.

Of course it's an alien space craft
Oummaumau is the Hawaiian word for emissary or scout.  How obvious can it be.
I'm surprised someone from Hawaii hasn't pointed this out.  They probably have, but the media would rather write about Trump's hair or Michelle's book.
