Why Harvard Scientists Think This Object Is An Alien Spacecraft

Narrator: We have a mysterious
new kid on the block. Astronomers call it Oumuamua. Which in Hawaiian, roughly translates to “first time visitor from far away.” Oumuamua is the first interstellar object ever detected in our solar system. Astronomers discovered it in 2017 with the Pan-STARRS1 telescope. And like all grand discoveries, it has raised more
questions than it answers. Where did it come from? What’s it made of? And yes, even the ultimate
query, is it aliens? That’s what two Harvard
astrophysicists posed in a recent paper, suggesting that Oumuamua
could be some type of alien spacecraft. And when we spoke with one of them, the idea didn’t sound as
far-fetched as you might think. Loeb: I prefer to adopt the
maxim of Sherlock Holmes that if you rule out the impossible, whatever remains, as improbable as it is, must be the truth. Narrator: Now a good rule of thumb is that aliens are always
the least likely answer. But here’s the thing, the
more reasonable explanation right now isn’t panning out. Most astronomers think that Oumuamua is probably a stray comet
from another stellar system. The only problem is that it
doesn’t look like any comet we’ve ever seen, because it appears to
lack that iconic tail. Loeb: There was an
anomaly seen in the data. And it cannot be explained by the most conventional explanation, which in this case is
a cometary outgassing. And so we propose an
alternative interpretation which is the only one I can think of. Narrator: But it seems
extreme to assume aliens just because Oumuamua doesn’t
look like a comet, right? Not when the Harvard scientists accounted for another peculiarity. As Oumuamua traveled
through our solar system, it didn’t follow the normal
path of a typical comet under the sun’s gravity. Rather, it slightly shifted off course, which couldn’t be
explained by gravity alone. Something else, some unknown
force was also at play, manipulating the object’s behavior. Loeb: I cannot think of
any other possibility other than the outgassing
that we find in comets, which seems to be ruled out because we don’t see a cometary tail, or the pressure from the sunlight. There is no other proposal
on the table right now. Narrator: Pressure from sunlight. It works similarly to how wind pushes against a sail on a boat. So too can sunlight push
against a spacecraft to propel it through space. Incidentally, we call these
spacecraft solar sails. There’s just one catch. Pressure from sunlight is extremely light. Lighter than the weight
of a fly on your hand. Which means in order
for it to be effective, solar sails also have to be
extremely light and thin. In 2010, for example, Japan’s space agency launched its Ikaros solar sail, which only weighed 1.1 pounds. But it eventually managed to
travel over 65 million miles from Earth on just sunlight alone. And it’s this type of force
that the Harvard scientists think could be propelling Oumuamua too. Of course, that’s if
it’s an alien made sail in the first place. Loeb: Well first of
all, I am not confident that this is the correct interpretation because we don’t have enough data. And so this is one possibility. I would highly recommend
people to read the paper. If they have a better idea,
they should publish it. Narrator: And as always,
not everyone agrees with Loeb’s hypothesis. Weryk: I think that their explanation, I think it’s in contrast
with what the data says. You know, we did consider that possibility in our own paper, which
was published earlier, and we dismissed it as not
being physically valid. You know again, there’s no
reason to think Oumuamua is anything but a natural object. Narrator:That’s Rob Weryk, who first discovered Oumuamua in 2017. Weryk: So we think Oumuamua still has ice and the sublimating ice
gives it a small tiny kick that gravity alone wouldn’t account for, but that the dust it has is much larger than what comets typically have. And so we just don’t see
that from the ground. Narrator: And yes, in all
probability, he’s right. Oumuamua is a natural object, like a comet or asteroid. But neither Weryk nor
Loeb can know for sure without more data. And sadly, Oumuamua is on its
way out of the solar system beyond the reach of our telescopes. So the best bet for solving this mystery? Weryk: So for Oumuamua
itself, it’s basically gone, it’s too faint to see from the ground. There’s no way we could
send a spacecraft mission, so we really have to find a second object. That would help answer a lot of questions that we don’t know. You know, I’m very interested
in finding a second one. It’d be nice if I found them all. Narrator: And Loeb already has some ideas on where to look next. Loeb: There should be quite a lot of them right now in the solar system. And some of them could be
trapped by Jupiter and the sun that act as a fishing net. And so some of these interstellar objects are bound to this solar system
after the first passage. Narrator: That’s right. Some of these interstellar objects might be right here in our solar system, trapped, and waiting to be found. It looks like astronomers may have more fascinating discoveries to come.

    The Object that is in the graphic is made to look like a rock.
    I will tell you this though….. The "Cigar shaped object" that flew into our solar system from above the plane was the long dead and debris encrusted remains of a vessel that, in a last and defiant act of bravery and despair, pointed it's navigation system toward our beautiful blue planet a very long time ago, in an effort to flee an enemy that had overtaken their Solar system, Galaxy and eventually, their entire existence.
    They were essentially a "Cult" in that they risked their lives on a mission that relied on the faith that their "God" would intervene in their suicidal self exile by means of providing them with a portal, or "a clear pathway", to their new Eden. A miracle which most likely did not occur and ultimately resulted in the vessel having no living being on board upon it's sad, lonely, silent and brief passing through our Home Space.
    They were not unseen though.

    At best, I surmise that it's a manifestation of some distant alien civilization's raw sewage relocation/compartmentalization program, where they jettison their poop at hyper-sonic speeds into space. Thus whilst in space over a vast many millennia, the "alien space poop" has gathered upon itself, & amassed into this GIANT mutherfucking Oumuamua thingy that scientists around planet Earff hypothesize to be an ultra sophisticated & high tech interstellar space craft manufactured by a highly advanced civilization.

    In closing, this just might be 1 GI'NORMOUS gaw'damn alien space turd, on a potential collision course with Earth. The human race might become extinct by way of BIG alien space turd traveling at a 300k mph impact. Chew on that!

    I think that it's structure is the most fascinating. It has "layers". They look like rocky sediment layers which would indicate it came from a planet or moon. It would be interesting one day when our future scientists explore it up close, match it's composition and trajectory with similar objects to confirm where it originated. It won't be that far away.

    I think you are all complete idiots.

    There are no bloody Aliens, can you not see that yet?. If they can detect this: "Scientists spot gas on ‘alien’ comet from another galaxy in world first", then why are they unable to detect any supposed advanced alien civilizations in our own back yard or Galaxy, that they claim are 10's of thousands of advanced civilizations.

    If they can detect gases on a comet in another Galaxy, then surely they must be able to detect other civilizations?. Do you want to know why they have not detected any Aliens?. Simple, there are none, not in this realm of existance and until you all realise this, the sooner you can just get on with this life. It is a shit life, we all know that, but it is not in vain or waste, as I know it goes on after this. Not telling you how I know and I do not have to prove anything to anyone here.

    But I can categorically assure you, humans are THE only supposed intelligent species in this realm of existance. That means once we are gone and we will be soon, there is nothing left, until the next dumb arses come along and so on and so on. Happened many times before, the people before us here on Earth, perished in the cataclysm. That species were more advanced than humans, yet they still ended up destroyed. This has happened many times before, ok. I think humans miss the point here. I think you humans need to follow lies and falseness to give you hope. The problem with most of you is you follow and believe the wrong thing, hence why you will never ever find out, even when you die. Once most of you die that is it, you are right, but some are a bit more lucky and do continue on in energy form. Again, I do not have to prove anything to you, but most of you, yes you are doomed. I am unable to give a % on how many of you are doomed, but it is high, real high, like high 90%'s.

    Stop following lies and chasing false hope. This is the life you live now, most of you are doomed when you die anyway, so you need to enjoy this life, because for most of you, this is the only life you will ever have. Again, I do not need to prove my claims, you either believe it or not.

    The Navy recorded these events using more advanced equipment than the ones used to detect Omuamua.

    They included: 1) radio waves, 2) infrared waves, 3) sonar, 4) visible light AT DIFFERENT vantage points for WEEKS!

    If this object doesn't respond well to another force, then that means that the object has far more force than what is trying to effect it. This would be force of motion. Either the moving object is moving too fast, having more force of motion than the influencing force has to alter its trajectory all that much or the object has far more weight, along with its force of motion, than the Sun has to pull on it.
    So, either the object is either moving too fast, making it want to keep its trajectory or it is far denser in it's mass and weight, for the Sun's gravity to alter its course.
    These are just my thoughts based on high school physics.
    Have either of these equations been ruled out? If so,then how?
    The only thing that seems to have convinced people that this is some alien space craft, is that the Sun's gravity didn't effect its trajectory all that much. I don't understand why anyone with a little education in physics would just conclude that its a space craft, when it has never altered course under it's own power.
    Is that guy a qualified scientist? I hope not!

    LoL it’s an alien space ship or it’s not, they still didn’t explain it yet. This is how primitive we actually are

    And UFO incidents are very common in United States. Eg. India, China and Russia very large in size but no incidents. Why ??
