humans: "the WOW! signal can't be from an alien civilization, because it didn't repeat"
also humans: "let's send this one-off signal to the stars with the Arecibo antenna!"
lmao true. Humans!
Got em
Great point. We always think of things in the form of how it relates to us as humans. We need to think outside the box. Who’s to say aliens are on the same technological path as us? Maybe they skipped something like oil and went straight to antigravity. Maybe they have elements from their host star that is able to create stable heavier elements.
Humans are not a monolith.
Let’s just pulse a laser off the moon into the distance
If the universe is a simulation, let's hope Bethesda isn't running it...
It just works!
Or naughty dog
But I want people to act like Oblivion npcs
@@ultrabomb1 that would be amazing!
This would explain my life's terrible writing.
The worst message to receive would be one tightbeamed directly to us.
"BE QUIET. OR IT WILL FIND YOU."
Sounds like a cliche movie quote from some lost soul.
Nah. It would be the one to follow, since we wouldn't have gotten the first message until long after it was sent: "YOU WERE WARNED. IT HAS FOUND YOU."
Or "the experiment will reboot in 9 Earth years"
Yeah, then the Doomsday Machine from Star Trek enters our solar system...
Only to find out 10.000 years later that this message was sent by an artist on a distant planet trying to prove some political point to their government.
Aliens enriching plutonium into their star could be 2 things:
A) The Aliens are just flexing on us
B) The found an effective solution to their nuclear waste problem, AND they are flexing it on us
Yeah, but then we found a star with plutonium in it and the scientists are all "yeah it's probably natural"
Yes. Flexin on us like Ronnie Coleman.
A review of our DNA reveals the message: "This DNA proprietary and copyright Ur-Quan Monsanto Terraforming Corporation, please return to head office on Betelgeuse Prime in the case of unintended dispersal or Panspermia event."
LOL
Suing then obliterating infant civilizations for unauthorized DNA usage
"Failed experiment #28166, do not release into biosphere"
LOL. This is so scary, thanks for lightening it up
youtube gets copyright struck by alien super AI for stealing their bots.
Or worse yet..... Propriitary Property of Microsoft
Don’t get me wrong, I like Event Horizon, but I’ve missed these kinds of videos. Good to see it again.
I was thinking the same thing the other day .
Same here! I like the shorter ones, i like to watch them on my breaks
Me 2 man....me 2
Same! I'm a big fan of John so I like hearing him speak a lot too.
Much love to event horizon ❤
Same. The channels have very different feels to them -- both are great.
I just love these videos
Very cool!
Wtf are you doing here?
it's the legend himself
**moves away from mic to read intelligent life signatures**
I remember watching you when I was 11, now I'm 24
Imagine if we finally find an alien radio signal, and after years of diligently capturing as much data as possible, analyzing it, somehow against all odds figuring out how it's meant to be decoded.... And it turns out to be an Alien version of Jackass, where we watch a crabman get kicked in the crabnuts while a bunch of other crabmen clack their claws gleefully.
I would go PPV prices for that.
Fear the crabcat!
People like you are why we have the Bible and the Quran…
The thought of the CMB as a memorial wall to previous universes and civilisations is both fascinating and terrifying.
John: "Odd nuclear materials in a star seems like a silly thing to do. It would take tons of effort and would seem to reap very little reward."
Alien 1: "I made the star burn neon black!"
Alien 2: "Pretty!"
Alien 1: "I know!"
Then our scientists find it and falsely think its natural and it flukes up our models of the universe lol
@@nothingnobody1454 alien TH-cam prank videos be like: “lol accidentally started a new religion on earth again.”
And imagine that was their science project.
The real message we will get...RAID SHADOW LEGENDS from far across the universe.
Or... Hello and welcome to DnD online.
No no I doubt that. It just doesn’t make sense
We would need to develop ASAP a relativistic kill missile...
Me: "they found a way to monetize the universe" *sigh*
We ve been trying to talk to you about your extended planet warranty!
Once again, John has awakened from his slumber to bless us with a small piece of his infinite knowledge to us, we are truly lucky to have a deity as benevolent as him.
God speed John!
Is this what the kids refer to as "thirsty"?
MurphyBoy ! John has a second channel, a long form interview format channel called Event Horizon, that I’m sure keeps him busy. Far from slumbering
Yeah, thank the gods,
This channel RULES. Every upload is awesome
Hmmmph! A very small piece of wisdom, mixed with a load of BS.
We missed you, John. Welcome back!
Yes !
We did!!
Thank you!
Hidden message discovered in the cosmic radiation background:
The Holy Grail can be found in the castle agggggghhhhhhhhhh.....
Look, if they were dying,
they wouldn't bother to imprint "Aaargh." Theyd just say it.
An unfathomably advanced civilisation wants to know:
"What's your favourite colour"
...maybe he was dictating...
Perhaps it's dictation?
Oooooohhhhhhhhh!!!!
It's such a tease being able to open our minds and take in the scope of the universe, but knowing I will never live long enough to experience any of it.
Thanks for the great video. Stargazing at night in an Iowan field, listening to John Michael Godier. What more could you ask for? Oh yeah, a blunt. This bowl is for you John. Cheers all.
I tell people all the time my biggest regret is I’ll die long before I can travel the stars.
ahhh a fellow man of culture !
i too will be rolling a blunt inorder to completely geek out with this video 😀
happy trips bro !
That does sound quite good
We might be lucky and one of the theories about universal consciousness is correct. That way we would find out (already know) all these answers, and not bound to the time dimension could experience everything at once, after we die. But as we don't remember anything before birth I doubt it'll be very useful because we'll never know until then. It's all very depressing lol.
The only thing that goes together better than astronomy and weed is astronomy and mushrooms!! Or alittle LSD😝
About time! Was afraid JMG was captured by aliens, wanting to silence him.
Quality over quantity ;)
Maybe he was!
@@suthinscientist9801 he was. cuz this episode is out of this world!
Make sure you check out his other channel!
They demanded to know Obama's last name but he wouldn't tell em. Good guy
Most terrifying "necrosignatire", I always thought, would be the discovery in some star system, of a planetary mass black hole.
yikes
Interesting thought. Almost Twilight Zone worthy! I wonder how it would be detected, though. Would it be periodic lensing of the star's light?
Perhaps, to wait out the lifespan of the universe, then only to emerge from the shroud of the event horizon? Planetary cloak that allows your enemies to think you've left the chat, but it's really just allowing you to see the universe around you go in fast forward.
Who's the say the LHC isn't manufacturing tiny black holes that are accumulating at the center of the earth
@@nosuchthing8 Scientists for one.
"We've received a message!", "What does it say? What does it say?", "Drink... More... Ovaltine...", "Dammit!"
"Here lies the noobnoob, a long forgotten race. They tried to blow shit up but it blew up in their face." -an epitaph on a galactic tombstone
Before watching: “Ugh, I’m worried about Covid.”
After: “Covid is a pretty small problem compared to being a civilization whose entire world or universe is dying.”
So now you know we are observing it in real time here on Earth? We have front seats for runaway Arctic amplification & that's just for starters.
Even later: "Buuuuuut ..... It's pretty stupid to worry about imaginary problems when I have real-world problems to face. Otherwise I might go back to worrying that the Nothing will consume us all if the Child-Like Princess is not given a name."
dont worry i had Covid, its not that bad. even my mother had it and shes 75 and she beat it too
If that rattles your cage, Ask the dinosaurs what they thought of asteroids.
Instead of worrying about imaginary problems I prefer to worry about things that people did a long time ago before I was born which after hearing about it has left me so traumatized I am unable to work or do much of anything.
Message in the cosmic background radiation: We Apologize For The Inconvenience.
"... but PLEASE don't push the big red button when you find it!"
Or:
“All Employees Must Wash Hands Before Returning To The Universe”
If you were ever to use my WC I'd have to say 'Sorry for the convenience'.😁
"We have updated our terms of service."
thanks for all the fish 🐟
I love Event Horizon, but there’s something really special about these videos on John’s original channel. So glad he’s still making them from time to time. Thank you, JMG.
An artefact passing through our system, such as a destroyed ship. You mean maybe something long and thin tumbling through space? Something that behaves a little bit odd and doesn't look quite right for an asteroid? I wonder if we might have seen something like that...
What if we were indeed left a message incoded in DNA giving us the keys to the universe, but to avoid tampering with their prime candidate for intelligent life they left it in another animal?
Like, say, the Dodo bird?
That's right! Let's kill them all to find that bloody scribble.
Oh...
Error correction theory says that no intelligent civilization capable of doing such a thing would embed a message in such a constrained population if they had any significant intention of communicating it to anyone else. Instead, it would be placed into a very large variety of organisms.
@@absalomdraconis Something like "The Chase" in Star Trek TNG wouldn't surprise me at all.
@@danaralston6688 I dunno. How do you preserve a message in DNA when it is constantly mutating and evolving?
@@desther7975 you don't lol,alien conspiracy theorist are wild
Scientists:
-Think of million ways aliens might leave a signature
-Actually detect said signatures
Also scientists:
-Nah it must have been natural cause
Lol so true
That's just how science works . Of course scientists are interested in receiving an alien signature but they don't want to jump the gun and assume something is of alien origin without ruling out the far more common natural causes.
Exactly. "It's never aliens!"
Hope they have toilet paper. Too that would be harsh for us.
Yes, it is called critical thinking. Give it a try, you might like it.
Really missed you.... Glad you have added to the top ten playlist one of my favourites....
Same
Make sure you're keeping up with weekly uploads at his other channel "event horizon"
I've lost count of how many times I've listened to this video to fall asleep.
Wow you made me reconsider my stance on the wow signal. For the longest time I thought it was completely disproven that it originated from extraterrestrials but now I believe it's very possible
I think it's reasonable to assume we are sourounded by techno signatures but don't know it anymore than an ant is aware of radio
I will even go so far as to say it would not surprise me if a citizen scientist in his garage with available technology could find something despite our inability to fully understand it
I doubt it. Anything that's been around for more than a few million years, which is extremely likely if any advanced species ever existed, would have signatures on a galactic scale. They'd also likely have sent self replicating probes across the galaxy, at least.
The only plausible way an advanced alien race might exist in our galaxy is if it's relatively young. Which would be a huge coincidence.
It wasn't too long ago that human scientists didn't believe in radio waves, they scoffed at the idea that invisible waves of energy could pass through solid objects, much less that they could be received again after passing through solid objects. "POPPICOCK I SAY!"
@@sparramore That's one of the problems with science.
There's only science where the money is aka grants.
And if any citizen scientist does find something or try to publish something
"iT wAsNt iN tHe jOurNalS!!!!"
This is why we see these dark matter/energy people so insistent on the theory when its slowly starting to fade when held to scrutiny from new data sets and experiments.
No money in discovering other theories because all this money has already been spent on this theory, therefore it MUST BE RIGHT!!!!!
Look at the parker solar probe, an easy instrument could have been attached to do some science regarding the Electric Universe Theory.
Did they? Nope. Same reason NASA's never figured out how to put a microscope on a rover, yet the Russians did in like the 80s.
Now where going to have to wait another what 20-50 years before another probe goes to the sun again. It's a hard place to get too.
For example, I can't do a gardening experiment in my own yard, write about it the academic standard, with proper protocols, because I have no degree. Therefore no ones going to vouch for some CITIZEN SCIENTIST to get published in the journal. Then you have all these phosphate junkies saying SEE THERES NO SCIENTIFICAL EVIDENCE TO BACK UP THAT METHOD (Hugelkulture). The money is in the phosphates, which is surprise, surprise is one of the biggest polluters.
Ant: What if there's aliens everywhere but we can't smell them anymore than humans can smell the queen?

Lolol
Deep.
We are constantly beaming signals into space...
The worst reply possible: *BE QUIET, THEY ARE LISTENING*
I love your Event Horizon feed but there's nothing like a top ten SETI list by JMG..
...I feel like this is just giving 2020 more ideas of how to mess with us...
Thank you soooooo much for returning to the old ways! I love it! Keep these videos coming forever!
I think we have seen one already: universal red-shift.
They are on to us, and they are all running away.
The year is 2169. Scientist, Cosmo Dyson Vaccum III discovered an imbeded message within the structure of the universe itself, which reads: "No ass to mouth."
And peace was restored on Earth.
Hahaha
Only for humanity finds out 5422 years later that it was done by a rogue artist so engulfed in layers of multiversal irony that she actually meant the exact opposite. Anyways, the piece was rejected as "highly misleading and confusing" by the art comitee and forgotten because at that time the artist was having another five comissions running. One of which made her multiverse-wide famous - the Cosmic Microwave Background - which is basically a visualization of governmental corruption regarding energy spending.
I still think one of the scariest scenarios is the one we've got (so far): no technosignatures. That is compatible with the possibility that animals spawned from Darwinian competition for mates and territory cannot adapt to the power of advanced technology (nukes, nanotech, AI, etc.); that technological civilizations are akin to toddlers left to play in a room full of loaded pistols and hand grenades, with the weapons increasing in power/danger level far faster than the toddlers mature.
Any technosignature of a civilization that "made it" into space is at least an indication that we can "make it" as well.
We might just be alone. Maybe life at all is just not very likely
Imo it seems this is most likely. It’s probably a large conglomeration of filters that when put together make the chance of a advanced alien civilization arising akin to flipping a coin 50 times and each one landing on heads (credit to Isaac Arthur for that parallel)
We think of ourselves as pretty advanced, yet we are a long way from being truly space-fairing and meaningfully detectable by other civilizations. Reasonable to say that the large technological gap we have to fill may lead us to even more dangerous and easily proliferated technology than nuclear weapons. Right now state and non-state actors can’t make nukes without being detected; even if they have the full picture the infrastructure is impossible to conceal. If in the future these things could be concealable and easy to create then non-proliferation becomes impossible and opens a significant threat to society from non-state extremists.
From the lens of bio-engineering deadly viruses or even crop/livestock diseases this will probably be a reality in the near future.
Humans: "One way we could detect another civilisation is elements in their host star that shouldn't be there"
*Detects a star with elements that shouldn't be there*
Also Humans: "iT cOuLd bE nAtUrAl CaUsEs"
This is one of my favourite channels. Not many spark my imagination, curiosity and love for astronomy. Links to papers and pages are the icing and the sound of his voice is the cherry. Never stop John. Ever...
Welcome back, John!
Maybe a signal could be “coded” in gravitational waves. For instance a kind of signature of an alien alcubierre drive ?
That is a use for an acubeire i haven't thought of, huh
Our patience has been rewarded with a 21 MINUTE VIDEO!!! This was worth the wait
Jupiter getting hit by a Nicoll-Dyson beam would be one hell of an introduction 🥺
My head-canon for Seven Eves just changed a bit; it was a relativistic kill vehicle that hit the moon.
"...announcing one's presence..." is asking for problems or asking for help.
I think therefore I am really thinking. Simulated substrate or no, my consciousness is real. I’m not disturbed by the possibility of being a simulation. I’m certain that it would make no difference to the essential reality of perceiving and thinking.
If we are a simulation, they need to stop and restore the system to the last restore point before year 2020.
Sure. "Real" or "simulation," we life and then we die, and so, presumably does the universe as we know it. Whether it's natural or artificial, the outcome for us would be the same, barring some interference from our simulating overlords. Would be tragic if we were obliterated so they could try running some other simulation instead.
It would be interesting if we were in a simulation meant to test whether and how long it takes for us to work out that we're in one.
"If we're in a simulation, the creator of the simulation might embed a message. What would that message look like?"

It's called dna do some research
*Talking about a partial Dyson Beam* "If such a thing is possible, we haven't seen one in this or any other galaxy..."
Only a galaxy, far, far away...
But that was long, long ago though
I stop by to watch this video every few weeks just to get good and creeped out. The voice, the music, the bouncing back forth from infinite possibility to infinite futility.
I watch them at night before I go to sleep. They help to calm my brain down.
I watch them when am high...they hit hard! You might wanna try it
The Berserkers of Saberhagen were actually weapons built to destroy the enemies of some long dead alien world. The mistake of its creators, was that the machines were programed to "Destroy enemy life", but the enemy life was never defined, so the machines destroyed any life it came across, including its creators. Loved those books growing up. I'm just surprised that anyone else would even know them, let alone remember them.
DNA encoded message: “do not harvest until yield reaches 10billion”
Or .....sterilize upon reciept of this transmission
sad thing is evening knowing that, were too dumb to prevent it

Just opened TH-cam on my phone and this was my 3rd or 4th suggested video!! I wasn't expecting it!! Awesome!! 👍👍😊😊
Wonderful video as always! Love this kind of content. Your lists may be the only "clickbait" on TH-cam that do away with the "bait" part.
The bait is there, it's just a nice juicy grub that's worth taking a bite out of
I get the feeling that we'll become aware of other civilizations (if they exist) when we figure out faster than light communication. If there is such a thing, we might find we're not the only ones on the line. If a civilization can travel great distances in the galaxy, they're likely using a superior communication technology to radio waves.
Well if you can do ftl travel or anything close to it you could send harddrives at those speeds as a data transport
@@orbismworldbuilding8428 Or if theres wormholes that can stay open near indefinitely as long as somethings supplied into it, you could just wormhole to another place and have a Galactic spanning Internet perhaps.
FTL communication/travel will never be possible because of how spacetime works with relativity. Any FTL method would violate causality and make paradoxes possible like killing yourself in the past.
Sub space transmission 😜

We need to get ourselves to Conjoiner level before we trip an Inhibitor trap.
thanks for another great episode. thanks for all the time and energy you put into the series. your vids are always the first to be watched bumping any other content.
thank you.
I'm putting my money on a derelict alien craft from a defunct alien civilization drifting through our system some day.
You mean like that "object " discovered a few years ago at the edge of the solar system?
I dunno man, the chances of having ANY direct collisions when the milky way and Andromeda galaxies merge is pretty low which is basically just a way of saying "There is a ton of empty space there." I would think the chances of a spaceship drifting through our solar system by accident would be even more remote, unless there were either some intentionality behind it, or there are just a metric butt ton of ships out there.
The probability of that is infinitesimally low.
The probability of us seeing it is even lower. We can’t even keep track of all the asteroids in our solar system.
ReivecS That's right. But I'll still bet my money )
I think we as humans have already recovered ancient alien probes that where sent to earth like 10000 years ago, simular to humans sending probes out to our solar system (think voyager) also our internet/computing tech has been built on these/a alien probe *drinks another beer*
JMG, you provide entertainment and education in a unique and thought provoking way. Thank you for your videos. Hoping all is well and keep up the great work
I could listen to your videos all day long, they are so informative, both terrifying and relaxing at the same time, but as mentioned before and I believe most importantly, besides me hoping you enjoy producing them, is just how informative they truly are, thank you Mr. John Michael Godier
I really like ur other channel but i LOVE this one...
Ive watched all ur videos and I was super excited to see a new one
Hope u and yours are well
Namaste from Pacific west coast 🌎⭐🌞🌛
John you're videos inspire me to learn more of what surrounds us, thank you.
The most likely signal, “ don’t take yourself so seriously “
The most likely signal: "Go fuck yourselves."
I find these aliens talks so interesting and about time I found a channel that talks about it now mate u have a new sub keep up the good work ❤️
Look up isaac arthurs youtube page. Youll love it. He has done videos with this channel too.
Wether we are alone (unlikely) or not, discovering the universe and exploring it will definitely be a fun journey.
Very good, what I enjoy about this episode is that it notes the fact that one, we may, probably, just find dead remnants of a civilization and two, that there are technologies that we couldn't even understand, like a caveman seeing a quantum computer.
I’m so happy you made another video! A great one, as always!
I enjoy your thought provoking videos John, many thanks and please keep them coming.

They probably will.
Finally! Man I was missing this videos so much, glad you’re back
the feeling when you realize that #1 has already happened
Your channel KICKS TOTAL BUTT MAN. I have watched EVERY upload. Always makes my day when you upload a new one. YOU ROCK
Great video as always.
The cynic in me could see something like "(some alien name) was here!" or "Eat at Milliway's" being encoded in DNA...or a picture of some alien making duck faces.
I'm not a specialist in this area, but I have heard that DNA sequences change over time unless they encode for something so vital that all cells with mutations in that subsequence are unviable. These are called conserved regions. So, the problem would be how to encode a cosmic "hello" in DNA but make that sequence be conserved.
Your videos always fail to disappoint! Thanks for the new upload
Missed your videos John :) keep up the good work
I really like the idea from the sow Star Trek Picard of an octonary star system being created by an advanced civilization as a means of warning others
Thank you for such informative, outstanding, and awesome videos John it's GREAT!
Always enjoy giving the brain a good stretch. Thanks!
Biologist 1: I found a message in the DNA sequence, dating back to the Cambrian Era.
Biologist 2: What does it say?
Biologist 1: "Kilroy was here."
You give me mad relaxation and ASMR. Your voice is so soothing its and the content let's my imagination run free, it's the best way to fall asleep. ❤
That’s so interesting. For me it’s the complete opposite. This topic is extremely interesting and I want to watch this video so bad, but his way of speaking annoys me, the constant going from high to low with his voice within one word on the end of sentences, such as at for example 4:29. It actually gives me misophonia vibes. Funny how different his way of speaking is perceived to different people.
thanks, John!!! I was soooooo excited this video said two days ago!!!!!! I've missed you! lol
Miss these lists from your original channel John. Glad to see you putting out a new episode. Also your voice help me go to sleep, I watch them before bed. Not a bad thing mind you.
Never knew the wow signal was going so slowly- this sadly means the civilization that sent it may already be extinct :(
The signal still travels at the speed of light. The thing that transmitted it is what was moving 10km/s. They might still be kickin!
But most civilizations are probably thousands of light years away. So you are probably right
I must admit that the possibility of DNA encoded messages is really interesting, BUT how would one keep the message from being subjected to mutation? Let alone for millions or billions of years! It would need to be a vital sequence (a sequence that when changed in any way, leads to the lifeform not being able to survive) in order to be kept from mutating by evolution alone, a situation that would most likely keep us from ever discovering that it even is a message in the first place. Or it would need some other mechanism that protects it from being influenced by radiation, chemicals, viruses, replication errors and chance. Such a mechanism would have most likely been found by now, since it would be a unique situation in all of the genome.
But genetics is not a trivial topic by any means and since it is not Your primary field of expertise, I'll just let this one slide :) Still a great vid, but I simply had to object here :)
There is a way to create error correcting genes and even program them to iterate a set number of times and then stop. These concepts are being tested in mosquito as a way to sterilize a population (mostly) but then stop working after x number of generations just in case it has unintended effects we can "undo" it. I think there was a radiolab podcast on this awhile back involving crazy uses of CRISPR but I may be confusing it with something else. But I would agree with your point that if such a thing existed in all life on Earth, we probably would have spotted that by now.
Or it could be a specific sequence that is repeated at regular intervals in all the genetic material. Sure, most of these sequences may have been modified through generations, but by studying the repeating patterns it would be possible to determine what was the original content of these sequences.
Like backups in IT, there are mechanisms that allow for corrections. Checksums, multiple copies etc.
Nature uses some of such mechanisms - the most obvious ones being symmetry. All life we know is symmetrical. It can be lateral symmetry, or radial (octopuses etc.), but it's there, because natural selection is set up so that it favors it - noone wants to mate with asymmetrical specimen, since it's a red flag warning about mutation and DNA damage.
I believe this is how humans will bio-engineer themselves within 500 or 1000 years. The reason why we're getting older and finally die is mostly because copying errors accumulate over time.
But if you had 5 copies of your genotype, and everytime something is off, your body would compare the copies, it could identify the "common denominator"; this gene is different in copy B, but the same in copies A, C, D and E , so it's obvious which one must be correct, and we can safely ditch version B because it's corrupt. No cancer, no aging, back to Eden.
Evolution is cheap, and its ultimate goal is survival of the species, not individuals, so it didn't waste resources on creating such an error proof mechanism. It would be an overkill. But deliberate bioengineering very well could.
There are probably ways to pull it off, plus these seem to assume tech beyond our capability. I'm sure we could even be capable of something like it one day.
