Just a reminder to everyone that it's fun to hope it's aliens, but Occam's Razor suggests it isn't and the real answer is likely something naturally occurring.
That's what the article says. It seemed a little better than the usual clickbait because they got that out of the way early.
Hmm not so sure.
Hear me out. I am not actually saying it is alians. Just questioning that it is not is the logical conclusion of occams razer.
First remember we have 0 idea atm. So occams assumes the simplist explanation is correct.
But over the past couple of decades. The number of planets we have identified has grown hugly.
We only recently gained the ability to detect anything earth sized. But hav already found several.
Evidence is indication that the number of potential planets that are capable of housing life is far from low. Even if we are taking one in a million planets able. Most scientists interested in the field now agree life existing somewhere is more likely then earth being unique for some reason.
So complexity wise. Other life having evolved and developed radio. Is no more complex then some unknown answer. In fact the idea that it is impossible to be alian life is more complex then the idea that it is possible.
Once we have more information. Things will likely change quickly. And I lack the optimism to claim its likely alians.
But occams razer wise. We have evidence of life creating radio waves and transmitting them into space. As we do it a lot. Where as some totally unknown thing we have never seen up to now is a little more complex as a solution.
The simplest explanation is a new kind of star, or a new kind of star cycle.
We have seen interesting radio signals before, they have all been explained by some sort of star behaviour.
The simplest explanation is NOT the evolution of an entire other species that survives all the way through to advanced tech to send radio signals.
The simplest explanation is NOT the evolution of an entire other species that survives all the way through to advanced tech to send radio signals.
That make a huge huge religion level assumption. That creats so much complexity to throw occam out ass a viable answer.
Is earth unique.
Without assuming the greatest abundance of evidence we have is unique. Then no occams razer is in no way able to make the existance of other planets having reached a similar status as complex.
I'll repeat again. I in no way think it is. I just challenge that occam is a viable evidence it is not.
As assuming earth is more complex then any other phenomenon in space. Requires you to explain why earthonly happened once. In the huge amount of time astrology is able to see. And vast space.
Any answer that comes is almost paradoxical in its level of complexity. Without more evidence.
The complexity involved to have sentient life evolved to the point that it can create radio waves is an astronomically small possibility. Having that coincide with our ability to detect such a thing is even smaller.
The history of "we don't know what this signal is or means" has always been "a new type/phase of star".
The only assumption here is that life is rare, and advanced life is rarer still. Which is supported by all of our science so far
Sorry but those are assumtions based on the idea that the earth is unique.
It is now estimated thatt trillions of plannests wxist in the milky way alone. And abiur 2 million galaxies in the observable universe. We have absolutly no idea how common ir complex the start of life is. Ands assuming we are in anyway unique is not a scientific answer with the knowlesge we have. It is just an assumption.
If life is common and we habe no way of knowing that is not the case. Then we also have ansolutly no way of knowing how common intelegence is.
If intelegence is common. It is reasonable to assume with time radio is an easy invention. Cos lets face it. Based on our data the least intelegent civilization we know off. And the most intelegent discovered it withing 5k years of discovering what we call civalusation.
So again the idea that it is complex for a life to evolve and develop radio is nothing but an assumption. Admitadly a common one. But not one based on any evidence at all. Instead one that is common mainly due to arrogance of mankind assumeing earth must be unique. Just because we lack the tech to see any others.
As for the odds of us developing in time to hear others. Again. The number of plannets and variaty of distances throw that argumebt in the trash.
The estimated number is so great. That no matter when i. The last *estimated" 13.7 billion years we look at. Odd ate high that nillions of planetz exist at the correct distance for us to hear them at some point in the last 100 years of radio until we die as a race.
Again i want to repeat. I am not saying this is such. I have no idea.so to say it is woild be absurdly arragant. And i am far to pessimistic to think such will happen in my lifetime.
I am only sayiing when you remove the (scientifically unviable based on current knowledge) idea that the earth is unique for some reason. Abd add it to the evidence we have found of how many potential planets are in the universe.
Occams Razer is in no way valid to assume it cannot or is provably not alians.
Occam's Razor is not a proof, it's a way to prioritize resources onto more likely hypotheses.
last 100 years of radio until we die as a race.
Based on our own experience, over the last 100 years, radio signals have gone from very scarce, to a cacophony of millions of high bandwidth compressed and encrypted emissions that look like random noise from anywhere outside our solar system.
If we consider an intelligence with an evolution similar to our own, "in the clear" transmissions that might've reached Earth 200 years ago, would've gone completely unnoticed, while now we could be getting the sum of their thousands of Tbps of encrypted memes, and be none the wiser.
I'm saying it's false to apply Occam's razor to this scenario and draw a conclusion that this is caused by non-human life.
I'm not assuming earth is unique. There have been many earth-like planets that have been discovered.
I'm not even assuming humans are unique, given all of space-time.
It is extremely unlikely that there exists intelligent life other than humans at this time (or within the window-function of time required for us to receive a transmission from however many million lightyears).
Like, it is vanishingly small. The insane series of events that has lead to an intelligent species being dominant on a planet is ridiculous, to be honest.
In other words, humans are essentially unique at this point in "observable" time.
It is extremely likely it is a natural phenomena that we don't understand, or even equipment malfunction, misinterpretation, miscalculation etc.
We have discovered unknown signals, then learnt what they are. Humans don't know everything.
We have discovered unknown signals, then realised it was a nearby microwave, or a dodgy connection, or whatever. Humans make mistakes.
The simplest explanation in order to not have to deal with a new research project is probably "aliens". But the simplest explanation is "natural phenomena we don't understand yet"
First rule of SETI: It can't be aliens until it can't be anything else.
Every new signal defy explanation for a little while, until it's explained.
Did we ever figure out what the WOW signal was?
Apparently not yet, astronomers are still waiting for the signal to repeat to appropriately study it.
METI president Douglas Vakoch told Die Welt that any putative SETI signal detections must be replicated for confirmation, and the lack of such replication for the Wow! signal means it has little credibility.[3
For now there are just guesses. If such burst isn't a fluke and repeats, astronomers will get a chance to better study it and provide a confident explanation.
Then they find out it's the the low battery warning on a carbon monoxide detector under the stairs of the emergency exit.
The title here is a little misleading. A signal that repeated once per hour, as in 60 minutes, would be pretty astounding, and might be a good way for a civilization with enough information about us to say 'hi' in a way we'd recognize. It would certainly be very strange to see a natural phenomenon ticking away the hours at a precise rate.
53.8 minutes, on the other hand, is a bit less attention grabbing.
I'd argue that a more precise timing like 53.8 minutes is more attention grabbing. It shows finer grained control of technology; a "look here! we can do this too!" sort of demonstration.
If we are the "more advanced" neighbor; then I could see that being done.
It's more that their knowing what an hour is would be impressive. Our selection of the hour as a measure of time is arbitrary outside of its specific context. It's just 1/24th of our planet's rotational period. We could just as easily split the day up into 10ths or 15ths or 7ths or whatever.
To broadcast a signal that's exactly an hour long to a planet that uses the hour as a measure of time might potentially imply someone trying to reference our way of measuring time. A signal that repeats every 53.8 minutes is on a timer that isn't specifically relevant to Earth in the same way an hour exactly would be.
That signal might be insignificant to us; but it may be their way of establishing a timescale.
The time may be derived from how long their planet takes to rotate...aka the length of one sub-unit of their day...aka 1/24th of their day.
Or, it could be the periodicity of the lifecycle of a cool bug they like, or it could be just a random period from any huge number of celestial objects we have yet to categorize. I have a guess for which of these options it is, personally.
Such a cycle is a cycle like any other. It's not "more precise" when it's shorter.
We attribute the 53.8 according to our scale.
RESPOND TO IT!
"Hello, Earth? We've been trying to get in contact with you about your local star's extended warranty..."
Do NOT let them recite their poetry to you!!!
Pulsar?
The article describes how the characteristics of this signal don't match any of the current models for neutron stars or white dwarfs. So quite possibly, but the question is how.
It’s a countdown ⏰
Jeff Goldblum Intensifies.
Personally I think the more complex pattern of having 3 different states being cycled through once an hour is significantly less likely to be natural.
That, of course, doesn't mean much by itself; it still is possible that it is natural and we just don't understand why. More research into how and why that is happening is absolutely required to answer the question. I just don't know if we will do it, or if we have the tech needed to fully investigate it yet.
when it can write out pi in a pule we will know peeps. we will know.
Well, if it's been running for a long time, it's up to some random point in pi and we missed the start. But we can still try to interpret the signal as digits, and check if this sequence appears anywhere in pi... Well what do you know, it does!
(disclaimer: it has never been proven that π has this property, but it is suspected)
