How `Oumuamua Got Its Shape

That's sort of part of the problem of figuring out what the heck it is. Other studies have concluded that there must be a lot of those things out there so how could such an odd thing be relatively common? This provides an answer.

At the same time, it also provides an explanation for why the surface of the object is so "dry", and how getting close to the Sun could cause volatile materials (H2O) beneath the surface to be ejected and produce that famous non-gravitational acceleration.

It's a nice neat package.

But I have never said that `Oumuamua is not a spaceship.

I will say it...
Oumuamua is not a spaceship.
See , I am not afraid of a true statement.

Oumuamua is not a spaceship.

Prove it.

It didn't have it's origins on Earth.
Nuff said.

That's threading a fine needle... close enough to become malleable but strong enough to not be ripped apart by tidal gravity forces... did their models determine what material it is made of? Maybe it was a dwarf planet that *was* ripped apart but it had a molten core that was stretched?

It did get ripped apart. That is what the model shows.

The tidal fragmentation scenario, as Zhang and Lin call it, provides an elegant solution backed by computer models that simulated the structural dynamics of a parent object as it strayed too close to its host star. As the models showed, a parent object like a planetesimal (an embryonic planet) or even a terrestrial, Earth-like planet, that ventures to within a few hundred thousand kilometers of its host star will start to distort—and distort very badly.

The process is akin to making a super-thin snake from a ball of Play-Doh. As the Play-Doh gets progressively thinner, smaller chunks start to shred off, with each of the bits still retaining their elongated shape.

In the case of ‘Oumuamua and other nascent interstellar objects, the hot, elongated fragments are quite malleable, consisting of a jumble of tiny pieces. As this loose collection of material ventures farther away from its host star, the bits rapidly start to cool and congeal to one another, forming a crust that defines the ultimate shape and structural integrity of the object. The ratio of the long axis to the short axis can be as much as 10:1, according to the computer models.

There are many asteroids and comets that look like 2 (or more) large bodies stuck together. Some were in a molten state when they were hit by others and just the centrifugal spin caused some to elongate, but look like 2 dollups with a very thin section beween them that somehow collapses. There could be many examples that we have not yet seen.

Hi Phage, a few months ago you shared a website where you can track different satellites etc in the night sky. It was a very useful website, but I lost it somehow. Can you share that again please?

As above, so below.

I don't buy their reasoning for it's shape. I think someone's trying to cover/hide the fact that we were visited.

There are some disc-shaped moons in the Solar System. The shape probably comes from fast rotation rate, and material accumulated on the "equator".

Here's one of them, Saturn's moon Atlas:

perhaps the very long, thin object is a orphaned structural metal component of a destroyed Dyson Sphere

thrown into Galactic Space by the exploding Star it once enveloped


~~ Ergo, just a glimpse of Galactic flotsam, which the Milky Way might be cluttered with ~~

A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to explain how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone...

Quite a possibility. Per reflections the object is either the long, oblong shape that we see in illustrations 99% of the time or at the other end of the spectrum it is disc shaped and only millimeters thick. Per SCIENCE! the only way it could be the thin disc shape would have to be manufactured... there is no way something that thin was created naturally.
