THIS DISCOVERY Will End the Debate on Oumuamua!
The Pentagon just unveiled a website containing declassified information about unidentified
aerial phenomena. Right now, the website has a few mind-blowing videos that are labeled
as "unresolved”. They show these bizarre objects flying through the sky and no one knows what they
are! These videos are the closest thing we have to concrete proof that there's something out there,
something beyond our wildest imagination. But it turns out there are even more mind-boggling
and mysterious things floating around in space. Take, for instance, this asteroid called Arrokoth.
It looks like a giant snowman! And let's not forget about the comet 67/P Churyumov-Gerasimenko.
The scientists behind the Rosetta mission studied it, and boy, were they in for a surprise.
But the granddaddy of them all is this object called Oumuamua. Say that three times fast!
Not only does its name sound like it's from another planet, but its very existence and
shape are a complete mystery. Some think it's a piece of a destroyed planet. Others believe it's
a piece of advanced alien technology sent our way on purpose. And the debate is now on fire.
In this video, I'll be your guide through the mysteries of Oumuamua, one of the greatest
interstellar puzzle of our time. ---
Oumuamua Identikit
Imagine if you were a famous astronomer, scanning the skies with your powerful telescope, when
suddenly you spot something extraordinary. It's an object unlike anything you've ever seen before,
a visitor from another star system. This is exactly what happened to Robert Weryk,
a talented scientist who discovered a strange interstellar object called Oumuamua.
Fun fact: Oumuamua means “a messenger from afar arriving first” in Hawaiian!
Oumuamua was first spotted by Weryk using the Pan-STARRS telescope at Haleakalā Observatory
in Hawaii. It was already on its way out of our solar system, having just passed its
closest point to the Sun. At the time, it was about 33 million kilometers away from Earth,
which is about 85 times the distance to the Moon. This peculiar object is estimated to be between
100 and 1,000 meters long, with a width and thickness ranging from 35 to 167 meters. It has
a reddish color, similar to objects found in the outer part of our solar system. What's fascinating
is that despite its close encounter with the Sun, it didn't show any signs of a coma, the
nebulous cloud that usually forms around comets. But here's where things get really interesting.
Oumuamua displayed a peculiar acceleration that couldn't be explained by gravity alone. Scientists
believe this could be due to outgassing, where volatile materials on the surface of the object
vaporize and create a small push, or even from the pressure of solar radiation. It also
rotates at a similar rate to other asteroids in our Solar System, but its elongated shape
sets it apart from most other celestial bodies. When scientists studied Oumuamua's light curve,
which shows its brightness changing over time, they noticed something unusual.
Instead of spinning like a top, it appeared to be tumbling, moving in a rather chaotic manner. This,
combined with its rapid speed relative to the Sun, suggests that Oumuamua originated from another
star system. Who knows were it came from! Well, actually we have some ideas.
It seems to be coming from the direction of the star Vega in the constellation Lyra.
Its incoming direction of motion is 6° from the solar apex, which is, according to experts,
the most likely direction from which objects from outside the Solar System would come.
--- Oumuamua Mysteries
Oumuamua has always been a matter of controversy and debate. For instance, how can we be so sure
it is an object of natural origin? I mean, we have powerful telescopes, of course, but who told you
that some alien civilization didn’t make it up and wanted it to look exactly like a natural object?
Yet, that might be their way to get into our solar system. Indeed, some have suggested that
its unusual characteristics, such as its elongated shape and non-gravitational acceleration,
might be indicative of artificial origin. However, the prevailing scientific consensus
leans toward a natural origin, stay with me, cause I will explain you why.
On a more scientific note, Oumuamua led to the proposal of the “comet-asteroid” idea.
What is that? Well, when scientists first studied Oumuamua, they couldn’t really tell
whether it was an asteroid or a comet. The object seemed to lack a visible coma or tail,
and some astronomers proposed that it might have a thin, hard to detect icy coating.
One thing is for sure: whatever Oumuamua is, it represents an unusual object, probably halfway
through a comet and an asteroid. Perhaps many such more objects exist right now in the universe!
Last but not least, Oumuamua might be a fragments of a larger object that broke
apart before entering our solar system. This hypothesis is based on the object's unusual
shape and its potential for being a shard from a larger parent body.
--- Reference Frame
Before we get into its weird trajectory, I really want to share this:
One interesting fact about Oumuamua that confirms its sneaky alien status is that
it seems to be coming from this special place called the "local standard of rest" (LSR),
which is like a secret hiding spot for stuff in space.
Only one out of every 500 stars moves as slow as Oumuamua in this hiding spot. It acts as
a disguise that helps the comet blend in and not be tied to any specific star. The way it
moves compared to the sun could show how the sun moves compared to the LSR. It's like it's just
chillin' on the ocean's surface and then BAM! The solar system crashes into it like a speedy ship.
It makes you wonder, are there other buoys out there, serving as a network of stations or signs
to show us the average space reference point? ---
Defying Cometary Physics One thing is sure: Oumuamua
has left scientists baffled and intrigued. This asteroid, or comet, or well, let's just
call it a "thing," has defied everything we thought we knew about cometary physics.
You see, typically, comets that pass through our solar system speed up as they journey
away from the sun. This is because the solar gravity gives them a push,
and the dust on their surface outgasses due to solar heating, providing an extra boost. But
Oumuamua didn't have any of this surface dust, which meant it didn't have the glowing halo or
tail that we usually associate with comets. And that's what got scientists scratching their heads.
One possible explanation for this anomaly is something called the
Yarkovsky effect. This is when small objects like asteroids, or tiny comets like Oumuamua,
absorb photons from the sun and then emit them, creating a kind of propulsive plume.
But even this effect couldn't account for the degree of acceleration that Oumuamua showed.
So, what could possibly explain this strange behavior?
That's the million-dollar question that scientists are still trying to answer. Now, some of them
think to have an answer to this cosmic enigma. Hey, before moving on, be sure to like or dislike

--- The Explanation
This means that there are three potential reasons for the observed strange propulsion:
nitrogen, carbon monoxide, or molecular hydrogen. These gases are commonly found in comets and are
known to easily transition between gas and solid states. We call them hypervolatiles because they
seem to really like being in the gaseous state. However, they can freeze sometimes.
Indeed, when Oumuamua was wandering around in space, we saw that those hypervolatiles
reached very low temperatures, reaching -269 degrees Celsius, or 450 degrees Fahrenheit.
Theoretically, we are able to confirm the possibility of the following scenario:
As the little comet was cruising towards the sun, the hypervolatile gases would be getting all warm
and fizzy. Like a soda bottle that's been shaken up too much. And then, boom! Outgassed plumes shot
out, giving Oumuamua a boost that even Usain Bolt would envy. Now, this kind of thing happens to
other comets too, but they're like the big guys at the gym. They're too buff to be bothered by a
little push. But little Oumuamua? Well, let's just say it must have felt the difference.
Like its the majority of its fellow comets, Oumuamua is really rich in water. But here's the
twist: when this comet was chilling out in deep space, the freezing temperatures turned that water
into ice, a special type of ice we call in its amorphous state. This ice had little holes in it,
like a sponge. And to make things even more exciting, cosmic radiation started playing
games with the water molecules, making some of the H2 break free and hang out in those sponge-like
holes. So, when Oumuamua swung by our solar system and started to warm up a bit, that ice transformed
into normal, solid ice, closing up those holes and setting the H2 free! And guess what? That's
what gave the comet the boost it needed to zoom on by. Seems like a cool way to produce fuel!
Astronomer Bergner states that when the water matrix gets all jazzed up,
it rearranges itself into a more chill and compact form. But in the process, those little
holes disappear and the hydrogen goes poof!" So, mystery kinda solved, with the possibility
to sleep better at night because it seems like no UFOs were involved.
But fear not! Bergner, Seligman, and the gang will be on the lookout for similar mini-comets
that are sneaky and dark when the Rubin Observatory starts doing its thing in Chile's
Atacama desert in 2025. They're on a mission to catch those comets releasing hydrogen gas.
Before 2017, nobody even knew these Oumuamua-like comets existed. But now,
thanks to the Rubin Observatory and its awesome astronomers, we're about to unravel the secrets
of their behavior, makeup, population, and more. Can't wait to get all the juicy details!
--- Outro
And that's a wrap on the mysterious object known as Oumuamua! We've explored its strange
characteristics, debated its origin, and even uncovered a possible explanation
for its natural propulsion. Oumuamua has certainly sparked a lot of curiosity and
debate in the scientific community and beyond. While some still speculate that Oumuamua could
be a piece of advanced alien technology, the prevailing scientific consensus leans
toward a natural origin. Its elongated shape and non-gravitational acceleration are still puzzling,
but scientists believe it could be a fragment of a larger object or a unique
combination of a comet and an asteroid. The Yarkovsky effect and the presence
of hypervolatile gases such as nitrogen, carbon monoxide, and molecular hydrogen offer possible
explanations for Oumuamua's propulsion. These gases, when heated by the Sun,
could have created outgassed plumes, giving the object a boost in speed.
So, what do you think Oumuamua actually is? Do you believe it's a natural phenomenon or a creation of
extraterrestrial intelligence? Let us know your thoughts in the comments below! Until next time,
keep looking to the stars and embracing the wonders of the universe. Goodbye for now!
