Oumuamua
Who thinks up these names!
Is this your own blog?
Thanks Voption.

I am pleasantly surprised with the high-level of discourse with only a tinge of wackiness, and just for fun.
I applaud you all!
totally tangential— Article in the WSJ last week, about how the YouTube algorithm sends you down esoteric rat-holes, surprisingly fast, especially with flat-earth et-al, stuff.
(I’d link to it, but its behind the paywall.
Shaken, not Stirred.
No need to click through if you just put the last couple of paragraphs of the blog here. Seriously, it wasn’t that long, especially if you clip off the begging for donations part.

A new analysis of the data obtained when the interstellar object Oumuamua flew through the solar system in October 2016 suggests that it is tumbling in a chaotic manner, and that the surface is spotty.
Straight away, they discovered that Oumuamua wasnt spinning periodically like most of the small asteroids and bodies that we see in our solar system. Instead, it is tumbling, or spinning chaotically, and could have been for many billions of years.
While it is difficult to pinpoint the exact reason for this, it is thought that `Oumuamua impacted with another asteroid before it was fiercely thrown out of its system and into interstellar space. Dr Fraser explains: Our modelling of this body suggests the tumbling will last for many billions of years to hundreds of billions of years before internal stresses cause it to rotate normally again.
To me, this data settles the question about whether Oumuamua is not an artificial structure. It is not. If it were, an impact that would have caused this kind of tumbling would have almost certainly destroyed it. Instead, it likely broke the original bolide up, producing many fragments, including Oumuamua and its elongated shape.
As for the objects spottiness:
Dr Fraser explains: Most of the surface reflects neutrally but one of its long faces has a large red region. This argues for broad compositional variations, which is unusual for such a small body.
It is really a shame we couldnt get a closer look before it sped away.
