KIC 8462852 Faded Throughout the Kepler Mission

even if it is a system filled with alien motherfuckers we will never meet them

Someone remind me - we know about variable stars. Why is this so surprising?

>No known or proposed stellar phenomena can fully explain all aspects of the observed light curve.

If it was a periodical dimming on certain intervals then I could entertain the possibility of aliums. But it's not.

so

>No known or proposed stellar phenomena
how about orbital debris you faggot?

And therefore Dyson sphere / swarm? Yea...

Is orbital debris a known or proposed phenomena? Oh my gosh yes it is

>Our first extraterrestrial contact is with a type II civilization

We're doomed, aren't we?

You see, if we cant currently explain something, then the ayy-fanclub always goes aaayyyy confirmed. For some reason.

Why? It means we are so far behind as to be totally non-threatening

Didn't it dim just like twice so far ?

>threatening

everyone always assumes aliens will be strange and weird but essentially human with humanistic desires and motivations/feelings

what makes you believe aliens have a concept of human fear in the first place

as soon as you ascribe any human attributes to aliens this gets ridiculous

Fear of threat is not a strictly human trait

Because any aliens will come about as a result of evolution, and so they will not be completely incomprehensible.

Of course, perhaps they might be like ants, with little to no individuality. But they would still have a fear-threat response of sorts, because if they didn't, the species would not survive.

alien visitors would most likely by artificial though. can't imagine the terror of being visited by an alien robot with no emotions, no feelings, no real concept of death or anything.

Cloud of kvegmoplasma? If I said it right, is it something right? Like when sun is covered by the cloud in sky so you cannot see it directly... Where can I get pictures so I can do analysis myself, will you get me free computer to analyse that? I dont want cloud computing, truth dissapears from that.

Which is completely incorrect.

It is debris. Occam's Razor is calling you a faggot.

>It is debris

Where's the IR then?

Infrared ? What makes you think every debris causes an infrared filter effect ? We are talking about huge ass masses that block 20% of the light here, not dust streams.

Two asymmetric orbiting black holes

Two huge black holes orbiting a star? Yea, sure.

Cloud of milliards of little ones?

Beings capable of interstellar travel could be the result of genetic engineering or artificial intelligence. They could be the product of processes we can't even imagine.

>Someone remind me - we know about variable stars. Why is this so surprising?

KIC 8462852 doesn't look like any of the known varieties of variable stars, and no analogue is known in the Kepler prime or K2 missions.

>If it was a periodical dimming on certain intervals then I could entertain the possibility of aliums. But it's not.

We're missing two prospective intervals. Last I heard, the light curves observed by Kepler actually fit pretty well with multiple Niven rings, which is the idea posted in the OP.

>What makes you think every debris causes an infrared filter effect

All bodies absorb some percentage of the light that hits them, and all bodies re-emit that light as heat. Orbital debris capable of blocking the percentage of light observed in the Kepler data should be emitting some serious black body radiation, but no one has managed to observe any at KIC 8462852.

...

Nope. We had two dips with inconsistent intensities and inconsistent intervals and inconsistent occlusion profiles. There isn't even a 3rd dip yet to call it a pattern, let alone asume anything artificial.

This is /x/-tier wishful thinking with zero evidence or scientific basis.

>Nope. We had two dips with inconsistent intensities and inconsistent intervals and inconsistent occlusion profiles.

If the two we've seen fell into intervals, we missed one just before Kepler launched, and not long after Kepler's reaction wheels failed. Those are the two I am referring to.

Since there are no dips recorded, there is no basis to assume there was any. There are only two known dips as for now and they don't fit a consistent interval. There is no known dipping before or after that and until we have such data, any discussion about "what if"s are pointless since we can't confirm any patterns.

Extrapolation and prediction is a core tenet of the scientific method, and many a discovery, including the Higgs Boson, were born from prediction. It's not a huge leap to guess that this might be periodic, and shitting on any discussion because we don't yet have enough data to say yes or no is counterproductive.

Yeah but if wishful thinking is all you have to desperately reach a conclusion as if this is some alien indication, it's not science, it's autism. And none of the evidence leaves any doors open for that kind of assumption. If we had a third dip around the same expected interval, I'd say you have a point and I'd be curious as well, but we don't. So until we do, this is nothing more than fairy tales.

>stop talking I hate this topic

not at all. you just need to discuss things with no evidence in

Look, we obviously can't conclude it's aliens, and questions like "what is the alien megastructure made of," "who built it," "what is the megastructure for," etc do not belong on but the nature of the dimming events, what kinds of bodies might be occluding the star, and whether or not the observed occluding events can be reasonably explained as natural processes are reasonable topics for Veeky Forums. "It can't be aliens, go back to /x/" is a waste of the thread topic.

>etc do not belong on Fucking hell. I meant to say they DO belong on /x/.

Look, we just don't have anything to work with okay ? The data is out in the open. There are only 2 dimmings that doesn't fit with each other. Thats it. There was one satellite listening to signals coming from KIC on almost on every frequency way back from 2015 and it didn't recieve anything at all.
Now any wild opinions built upon this very data will be very primitive and impossible to prove at the moment. Especially when you insert an inexistent 3rd dipping.

So I don't really know what is there to discuss that would fit in a scientific frame with the current knowledge we could gather.

>So I don't really know what is there to discuss that would fit in a scientific frame with the current knowledge we could gather.

The shape of the light curves, the overall trend line of the star, and the existing spectral data was enough for today's new paper to be released. This star is just plain weird, to the point that it's very, very difficult to explain the observations.

What's more likely? that we as humanity fight the aliens to secure our future as a species or we interbreed with them and get wiped out.

No take-backs.

>What's more likely? that we as humanity fight the aliens to secure our future as a species or we interbreed with them and get wiped out.

We have to wait until next year to get a better understanding. Also if its AYYSSSSS, then they would know we're watching. They would have figure out how to communicate across vast distances without waiting for long periods of time. I personally think this is some star about to go supernova or collapsing onto itself.

Then prove their existence.

>Also if its AYYSSSSS, then they would know we're watching.

How would a prospective civilization know we were watching? Recorded history goes back 5,000 years, Pre-history is believed to extend back another 200,000 to 1.5 million years, and Hans Lippershey didn't even invent telescopes until 1608.

Yes, multiple rings with gyroscopic motion could explain everything.

phenomenON

>Also if its AYYSSSSS, then they would know we're watching.

They probably wouldn't, honestly. They're 1500 ly away, there's absolutely no reason for them to notice us or even focus in our direction in particular. It's possible that, through sheer chance, they may have catalogued our Sun as a life-bearing star, but since 1500 years of light lag puts them well behind anything that could possibly signal the existence of intelligent life on Earth, there's no way they could know we were looking at them right now.

If they even exist, which I do wish to clarify is extremely unlikely.

>since 1500 years of light lag puts them well behind anything that could possibly signal the existence of intelligent life on Earth,

The earliest visible indication of intelligence would actually be a spectral shift associated with agriculture, which could go back as far as 12,000 years.

>>this reply was only for >8250783, my phone glitched

Alien's would've also had to survive, so there would be a mechanism for survival which will make them want to survive in face of threats.

Imagine if ayliianes were real, and they would share their technology/knowledge with us, and we get like superpowers and shit shiiiiiiiiiiiiiiiiet

I hope aliens read this thread and raped every single one of you.

Like one by one.

This. They'll know something is up in the atmosphere. Changing the landscape of the planet to suit your dietary needs will result in spectral shifts that don't correlate with something natural.
Although unlikely they're ayys we don't know how they'll find us or if they have something that looks for life in a general vicinity of the galaxy. Maybe we don't fall under their definition of sentient species.

Life is a natural phenomena
Therefore life exists in the universe

>Life is a natural phenomena
>Therefore life exists in the universe

We've conclusively shown that it exists on Earth. We have no evidence that it exists anywhere else, and we have no good reason to believe it exists in close proximity to the Earth.

>its an unknown phenomenon
>Veeky Forums logic: it has to be ayyyyy lmao.

Orbital debris has been suggested. A long time ago. From about the beginning. And it was found to be highly unlikely.

Have you concluded otherwise?

idiot

>What makes you think every debris causes an infrared filter effect ?
Why talk about filter effect??

The issue here is that debris would absorb short wave heat and re-emit as longer wave infrared radiation. And the question remains: just where is that long wave radiation?

>We are talking about huge ass masses that block 20% of the light here, not dust streams.
Blocking is either by absorption or reflection (away).

Absorption: that would mean heat absorption and temperature increase and thus re-emission.

Reflection: that would mean the radiation was reflected somewhere and that has not been seen. Also no plausible mechanism for a reflection.

One tail wagging a dog.

Milliards of tails wagging one dog.

Not plausible.

Not necessarily.

>They could be the product of processes we can't even imagine.
Earth's biosphere and civilization are perfectly detectable using hypertelescopes.
They would be aware of our presence.
As would others. If they exist they likely don't care or just observe.
My theory is that these are mostly old machine intelligences occupied with abstract mathematical theories and simulation of universes and we are simply like bacteria to them.

>More complex scenarios in which the ingress timescale
re
ects the spreading of debris along its orbit after a re-
cent collision or the precession of an occulting disk into
our line of sight could perhaps explain the appearance of
a transit. For example, a cloud that slowly increases in
density would manifest itself in the light curve as induc-
ing a change in
ux similar to that observed in Quarter
12. However, to produce the apparent
at bottom of the
supposed transit event, such a cloud would then need to
be extended over a fraction of its Keplerian orbit and
would need to maintain an approximately constant den-
sity through its entire length as it passes in front of this
star.

They would be able to observe our biosphere through advanced telescope arrays.
Possibly hypertelescopes or using focal points they could image Earth enough to see signs of civilization(I think Babylon and Rome were visible as points of light from space during the night, maybe agricultural fields too)

>The earliest visible indication of intelligence would actually be a spectral shift associated with agriculture, which could go back as far as 12,000 years.

That's a very good point, I didn't think about this one.

>hypertelescopes
And what is this?

there is proof life used to exist on the moon. six times, in fact

Why would their creators have not built/taught their AIs with many of the attributes that contributed to their success as a species.

Why would they put their legacy on retard robots?

>implying the actual aliens wouldn't be like that

>there is proof life used to exist on the moon. six times, in fact
Awesome.

I am looking forward to sources for this.

>The earliest visible indication of intelligence would actually be a spectral shift associated with agriculture, which could go back as far as 12,000 years.

Which spectral shift wold that be? If you think of oxygen, this shift was caused by bacteria during the oxygen catastrophe and was not related to intelligent life. If on the other hand you think of chlorophyll that would be algae in the oceans and plants on land, neither of which are considered intelligent.

And 12,000 years ago we had an ice age. What agriculture are you thinking of?

>I am looking forward to sources for this.

>And 12,000 years ago we had an ice age. What agriculture are you thinking of?

Neolithic agriculture dates back to 9,500 B.C. Not quite 12,000 years, but close.

>Which spectral shift wold that be?

Swathes of ecosystem being stripped out and replaced with a much smaller variety of plants.

yeah how STUPID does he have to be to think that we, worthless humans, are the only ones in this magnificient universe! doesn't he know how many planets there are out there which are PROOF that there is extraterrestrial life.

way to go my fellow redditor!

>the principle of relativity is sooo reddit
>muh internet wars
this is an 18+ site

The distribution of life in the universe is primarily a question of statistics, not relativity.

Check out the rare Earth hypothesis. Smarter people than you have thought long and hard about this.

In any case, all parties are comically missing the point; the sample size of known planets with life in the universe is one.

>Swathes of ecosystem being stripped out and replaced with a much smaller variety of plants.
This would have no effect on the atmosphere. Replacing trees and and bushes with corn and wheat makes no difference. It's still pumping out oxygen. Do you even know what "spectral shift" means? Do you have any experience studying spectra, especially that of other planets?

It's not about pumping out O2. People till the land, grow their crops, harvest them, dispose of the waste, and generally construct a nice and orderly system to do the job. With a Sufficiently Advanced Detector, polarimetry could be used to detect agricultural activity; it's already widely used for precision agriculture. Detecting it on planets would be an entirely more complicated affair, but we're talking about a hypothetical alien observation scenarios to begin with.

so? seems you are missing the point

>so? seems you are missing the point

Apparently I am. What is the point?

>Everyone but me are comically missing the point
Right.

>the sample size of known planets with life in the universe is one.
That is not the problem. To the contrary, that is the reason for the rare Earth hypothesis.

please read

In absolute terms, what's your point? Let's stop beating around the bush.

>rare Earth

We only identified 1,700 planets. 10 of them are candidates for life. We haven't proved nor disproved the existence of life there. 1690 are ruled out on principle of being too different to Earth.

There are billions of planets in the observable universe, and 10^23 more in the whole universe.

What does it matter if it's aliens or not? We cant go to them, we can't meaningfully comunicate, we can't even observe them properly.

it's only 1700 light years away

oh sure, that would mean it doesnt matter.
