What Is The Scariest Theory Known To Man? 

If you hear the woods go quiet, there’s a predator around. But that predator is probably you. Everybody was fine til you showed up.

To me the scariest one is: If time travel is possible, even if it takes us 10000 more years, then we've already discovered it, used it, and changed things.

One of the weirdest/scariest is the Bicameral Mind. Essentially that the old gods were the other side of our brains talking to us. But we didn’t acknowledge it was ourselves.

Scariest theory to me is the theory that your entire life has already started and ended at the same time and your experience is just your consciousness processing this

11:12 - This is the Uncanny Valley effect. And it's probably because, at one point, our species (Homo sapiens) was not the only human species on Earth. We evolved the ability to tell our species and other human species apart. And, guess what? We ended up being the big bad predator that destroyed the other human species.

I don’t know how someone can be so bad at video games I couldn’t even focus on half the stories

The scariest theory is that we’re basically an ant farm for a higher intelligence.

one of scariest concept that i ever known is humanity is a single entity that reincarnated over and over again. basically everyone is just another you. when you die, you forget everything that happens in your lifetime and born new. you continue this cycle until you're ready to evolve to higher tier of entity called gods.

Technically speaking, because of how brains work, every human lives in a simulation.

4:05 Every time I hear about it, I want to point out: corpses won't "act nonhuman" - they won't act anyhow cause they're dead. But the "fear of contracting a disease" part? Yes. Rabies, man! Doesn't kill a person right away, but makes them dangerous for others. Same can be said for a lot of infections, and a sick person will definitely act odd.

This isn't what I'd call a scary theory, but I feel discouraged by it. It's my "Time bubble" theory. Light travels at a constant rate. On the universal scale, it's kind of slow actually. Let's pretend we have a perfect telescope that can zoom as far as we want to look with perfect detail. Yay! Now let's observe an object 1 Light year away from us zoomed in so close it's like you're standing there. Well, the light your telescope is taking in for you to see that left 1 year ago. You are looking 1 year into the past. That object you're seeing is not presently in that location, and a year has passed since what you're seeing. Let's now pretend that you got in your merry little space ship with its merry little FTL warp drive, and brought your telescope on a brisk 6 trillion mile cruise out there. You are now 1 light year away from Earth. You use your telescope to look at Earth up close. You are seeing 1 year into Earth's past. In theory you could try to remember where you were a year ago, and actually watch yourself on Earth through the telescope (if you could warp drive out there faster than light). I'm 31 years old at the time of writing this, in theory if I went about 31 light years away from Earth with a perfect telescope, I could watch my own birth occur. Okay let's get bigger. The Milky Way galaxy is about 100,000 light years across. You fly out to the edge of it, and you zoom your perfect telescope all the way to look at the farthest object on the other end of the galaxy. A cute little blue moon. You are now looking 100,000 years into the past. Since your merry little ship can travel faster than light, you go ahead and fly across the Milky Way in 10 minutes to check out the cute little blue moon, but when you get there it's an entirely different place... that blue moon is a reddish brown rock right now... because 100,000 years have passed since the light left the object you looked at. So because light moves so incredibly slowly on a cosmic scale, the farther we look into space the further we are looking into the past. We do not get to observe the distant present day. This makes finding other intelligent life VERY much more difficult, and it poses the same challenge for others finding us. If a planet with intelligent life exists right now about 5000 light years away, and they have a perfect telescope to see Earth with, they would find life... but our peak technology at that time might've been the wooden spear. We exist in a time bubble caused by light's slow speed, the farther we look out, the further back we see in time. Outside of our bubble is the distant present day, and it is beyond reach. There's no current way around this.

You can carry out Pascal's Wager for any god. This is why I call it Pascal's Roulette whenever the fallacy is brought up.

Honestly the scariest theory of mankind is the simulation theory, imagine living your whole life only to "die" and find out it was never your own to begin with, if everything in our existence is a fabrication from another world than no matter what you do or how hard you try or what connections you make you'll always be apart of a network and the only brief escape is death until your memory wiped and put in a new vessel. Terrifying shit.

as Stephen Hawking once said: “If time travel is possible, where are the tourists from the future?” I love this theory because it’s true. If at any point in the future we discover time travel, that means that we would have to had travelled back to modern era, considering that time travel would realistically create infinite timelines. The fact that we haven’t seen future tourists could be evidence that time travel to the past is impossible.

Whenever I read about terrifying existential horror scenarios I always think about Stephen King's short story "The Jaunt". That story has stayed with me more than any other Stephen King novel.

The clone thing is actually real, not in the way you put it but, I mean cells die and get replaced all the time, so physically you are not longer what you were 7 years ago. You can look at an old picture of you, let's say 10 years ago, and think that that person is actually dead.

The uncanny valley thing isn’t as deep as we think it is. There were other humanoid species and we killed them. Warred with them. They almost looked like us but they were competition. Probably across hundreds of years. So we don’t like things that look like us but aren’t quite us.

One time we visited a spot call witch trot road late at night. It’s a spot in Maine that is supposed to be haunted. We parked the car and walked down the dirt road a bit. Everything went quiet. A silence myself or my girlfriend never heard before. So much so we just looked at each other and turned back. I’m 35 years old and to this day we’ve still never experienced a silence like that.

The REAL scariest theory is: There is a Heaven and a Hell but the religion you needed to get to Heaven died so long ago that the language of the people who believed it is dead, and now we're all going to hell and there's nothing we can do about it.

“Who will hear us?” “The SHOA” “SHOA?” “Space Home Owners Association”

Why does no one consider the fact we spend thousands of years living with humans that looked slightly off. It’s no wonder we are afraid of things that look almost human but not quite

I have heard of that short story before! Where humans have been sending out radio signals and one day we receive a message back which reads "stop it they can hear you" or sumn along those lines! Honestly those stories of aliens finding us/ humans communicating with extraterrestrial beings are my favourtie genre

I’m don’t remember the name of this theory but, Imagine that the more trauma people experience the more mental illness are made. This causes more mental illnesses and in turn this creates more trauma. This results in society becoming mentally Iill and unstable as whole which leads to more war genocides etc.

To piggyback off one of the first ones in the video about simulations: There is a quote by somebody (not verbatim but close) "Either an advanced civilization always ends up destroying itself or we live in a simulation. Those are the only two options." Basically, with growth in technology, as long as we don't destroy ourselves we will inevitably create simulated universes. If we are able to create a simulated universe, especially one that is advanced enough to create its own simulated universe then there is no reason to believe that we are the first. If this can happen an infinite number of times (your simulated universe makes another simulated universe and so on) then statistically the chances we are the original is basically zero.

Story 4 The Fermi Paradox. It is not just ONE Great Filter. There are many we THINK are there. And according to scientists we have passed the vast majority of them already. But I believe the Fermi Paradox is fundamentally flawed. Fermi came up with this back in 1950's IIRC. We were just starting to get a good idea of how old the Universe was. And Fermi was pretty sure we would destroy ourselves with nuclear weapons. Even at our peak during the Cold War we did not have enough to kill off all life on the planet. Right now we have about 16 megatons of nuclear weapons total world wide. Mt. Tambora IIRC exploded with a force estimated at 33 gigatons of TNT. Or many times our combined nuclear arsenal. And remember Hiroshima was fully reoccupied in the 1960's after being directly bombed with a nuclear weapon about 20 years before. I think the Fermi Paradox is flawed because the basic premise of it is if the Universe is so ancient (about 13 billion years old) why then are there no other civilizations out there. First while 13 billion years is a long time to us, that is because we live relatively short lives compared to even some other creatures on Earth. Compared to stars that have life spans in the billions and many in the trillions of years, and new star formation is not expected to end for hundreds of billions to a few trillion years from now, and the over all life span of the Universe is estimated in the quadrillions and quintillions of years (and those are the conservative estimates); the Universe is itself quite young. Second. For the first millions of years the Universe was too dense and hot for even stars to form. Then for the next few billions of years super sized stars formed that went super nova in millions of years to make elelments heavier than Hydrogen. No planet could have formed in the early, early universe as only Hydrogen existed. Third. Earth formed 4.5 billion years ago approximately. It took until just over 100 years ago for us to even start being able to hear or send signals. So I and others believe the real answer is we are the First in our area and maybe even in our entire galactic super cluster. Given that the age of the Universe is young in terms of the Universe and not in terms of how many generations of us have past.

Story 12 is an episode of the outer limits, where we were given the technology to teleport but it’s actually just cloning you as exact copy on the other side. A glitched/event happened and two of the same person exists and one must be “deleted”.

Does my man’s mic randomly teleport to behind his head while he’s talking at random points throughout the vid or is it just me?

Most of these are incredibly poorly thought out, arbitrary, and only designed to instill fear. Also, they're based on completely unprovable premises.

Scariest theory is that we always see the negative things in conspiracies. What about another being hears the record and sees us in a positive thing. It's always negative......

If all goes quiet in the woods I'll just remind whatever it is that humans are the apex predator and not it

I had a buddy who used to be scared that he was the only real person in the world and everyone else was a figment of his imagination. I always thought how weird it would be if he was right. Some other dude than me being the only real person, while I myself wasn’t actually real.

If an alien race wanted us to destroy ourselves before they invaded and colonized Earth, they'd only need to transmit a two-word message: 'We're coming.' 🤪

Its not " Dark Force" its " Dark Forest"

my theory, every fictional universe we create, creates a parallel universe in real life in which the events of that fictional universe are played out or the works we create are memories or glimpses into past universes, past selfs. meaning Every Work of Fiction is True in Another Universe

The first one is scary but sometimes I wonder if they have swung by, took one look at us and went 'ew...no' then flew away. 🤣 Our planet is probably the weird kid no one wants to talk too.

How about the one that states there are an infinite number of universes, which means there an infinite number of possibilities, and we just happen to be in the universe that has NO OTHER life but us, the people of earth

From story 3, I’ve had that exact same thought for years literally since I was kid. I was always curious on why do I (Myself) see out of my eyes, like In 1st person, but everybody else is in 3rd person to me if that makes sense cause I can’t see out of their eyes, why am I (Myself) in control of my body & thoughts, like what makes me… ME!? If that makes any sense at all but I’ve had this feeling pretty much as long as I can remember and I’m not religious, I grew up religious but had a falling out, now just don’t believe necessarily but I do In a creator. (Higher Power) Another thing sorry but maybe this one is just me, but when you aren’t even thinking of a specific thing and a thought pops into your head out of nowhere! The subject of conversation had no relevance to the thought that appeared in your head. Is that somebody or something putting that thought into my brain same goes with false memories, if it’s false and you remember it so clearly, was that put there by something or was it simply just your imagination idk but pretty interesting stuff.

I'd like to think the fermi's paradox as the scariest because you just don't know what is out there which stems from the most primal fear,the fear of the unknown.

My absolute favourite theory is The Great Filter Theory, considering that we could of already discovered a technology that has pushed us past the point of no return and have already set about the course of self annihilation, or we discovered this technology and corrected our actions and have now passed the great filter.

Solipsism is what I’ve experienced when i took a god dose of shrooms “am i the only person that’s experiencing this all”

2:16 Wait wait wait wait how in the hell do we have 30 minutes to protect important electronics if light travels from the sun to earth in 8 minutes.. the math ain’t mathing right

It’s *DARK FOREST* lol not dark force. it’s used as an example of being alone in a DARK FOREST… where you’d stay quiet as to not alert predators.

I'm so sick already of AI read RU-vid videos.

While it may not be related to this video, an interesting philosophical discussion you can have with someone can go like this: Go to the other person, and say “prove to me that you exist without having me witness you” And what this means is that the other person can’t use any means that involves your senses. The idea being that you could be in the matrix, and your senses cannot be trusted because they are all electrical signals being sent to your brain. Electrical signals, which can be manipulated. I have yet to talk to someone that can really prove they exist. I can’t either. It has stumped everyone i have asked.

#18 quantum is a measure, there is no such thing as quantum. Waves are what things do, not what things are. Time is a measure not a dimension. Quantum entanglement is just the Dielectric.

Got a few though I don't remember what their official titles are. An old forgotten one was about what happens to society that perfects the concept of beauty, such as implants and restoration surgeries. Sure at a glance it'd seem like a utopia with everyone being able to be their most physically ideal self, but what's to stop said powers that enabled this possibility from weaponizing it to enforce conformity & compliance? It'd become a dystopia at the flick of a switch, with the upperclass deciding who gets repaired & perfected while keeping upstarts disfigured and disabled. Another theory was of duplicates, whether it's because of cloning or time travel or parallel universes or whathaveyou, it's said you should kill your doppelganger because both of you innately know there should only be one of you. But then there's the question of why, is it because some higher power knows someone could cause significant harm/change having extras of themselves, or is it related to the uncanny valley and our desire to avoid or destroy things that shouldn't be imitating us? And lastly is the reminder we're conveniently in the goldilocks zone, just at the right orbital spot around the sun without burning or freezing. Ironically a common doomsday trope is for a huge asteroid would crash into earth and the impact would destroy us all. Except that'd be a best case scenario, what if such a devastating encounter didn't hit the earth but merely drifted through our solar system? If its gravitational pull was significant it could pull the moon out of orbit leaving the earth to uncontrollably wobble, if it had an immense pull the gravitational wave could nudge the earth into a spiral either into the sun or out into the void. And that's not considering if it caused a domino effect of planetary collisions or deorbiting.

Wouldn’t solipsism create a paradox? Because if one person was in fact the only self aware person in the universe, that means no one else is conscious. But from another person’s perspective watching this, they would also be the only self aware person in the universe. This chain continues until every person in the universe is theoretically the only self aware one, meaning all of us are self aware.

0:58 essentially what the movie with the "Shimmer" in it with Natalie Portman in it was all about. a comet with strange particles on it hit earth and was spreading.

these are just things i think about all day lmfao

Time being cyclical. This timeline should never be re-experienced.

If you like the first story, I highly recommend The Three Body Problem (book series and netflix series) It's all based on Dark Forest Theroy

Reapers.. that is all. Story 28 : Synths!

I've heard that our galaxy is in the Local Hole Void and all other galaxies in the void are empty because the probability of life forming in galaxies in a void is very rare but we're that one place where life was able to form. Though our void is not that empty because we do have the local group and a supercluster of galaxies nearby. There's also the biggest void known in the universe called the Boötes Void where it's like something hundreds million light years big but only has 60 galaxies in it. A youtuber compared it to like finding only 60 items or things in the entirety of the US. Initially it was known to be only 8 galaxies. And there are two theories I found on the internet abt it; one is more realistic, other is theoretically but my favorite one. The realistic one is that that area where it was initially filled with small and young galaxies that eventually merged together until there was only 60 left. My favourite theory is that there is a type 3 civilisation on the Kardeshev scale that was formed within the Boötes Void and they've been just going around consuming the energies of all stars around galaxies and forming dyson spheres around stars for 700 million years, since the Boötes we see now is from 700 million years ago?

3:35 animals do have a inherit instinct for detecting danger whether natural or not. They’re incredibly alert to changes in their environment. Even domestic animals still bear that instinct to the point that they have been shown to be sensitive to the supernatural.

The clone one reminds me of how star trek transporters work.

I love how there's scary theories space aliens and stuff then randomly a doraemon theory

I'm pretty sure you're not ready for emps or solar storms. At this point our grid in the US can barely handle the extra load brought on by electric cars

All of these are nothing compare to the theory of hell afterlife. Everything can kill you but to be tortured eternally, that's the worst

if you didnt use an AI voiceover this vid would hit different.

Dark Oxygen theory posits a majority of prospects for intelligent life are stuck under ice sheet ocean planets and can never escape. Truly grimdark.

The scariest one for me is that...God might actually be real and the reason people are so distracted from that fact is because the devil is a genius playing his cards right.

Scariest fact i knw. My cat owns me but pretends hes the pet. When im the real pet.😂

Is it not possible that in order to reach a technological point in our civilization to create unlimited renewable energy, we must first spend a few centuries utilizing fossil fuels? We could then use the new technology to reduce pollution and restore Earth to a cleaner state; if this is true, any effort to halt fossil fuels would actually prevent humanity from reaching this goal. Also, by reducing our population, we limit the amount of minds that can collectively create new breakthroughs. Tl;dr: The more we use fossil fuels and populate the planet, the faster we can reach clean energy.

I’m stoned outta my gourde, should I be watching this? Edit: bro I almost died in a car accident 3 years ago now and I always wondered if I had been replaced by a clone. Fuck man.

Life is basically a kind of teleporter. Your body at 10 is not the same one at 20, or the one at 30 or 40 etc. Your constantly getting replaced. It seems that your consciousness is your biological constitution. So, if teleportation existed, then it could actually transport tour consciousness too.

What's the gameplay in the background? Looks fun as shit

On The Dark Forest theory… it’s basically guaranteed to be wrong. Number one: our radio signals are too weak to be picked after more than 1 1/2 light years. Number two: the Golden Disk’s map is worthless. At the time had only spotted 14 Quasars. Now we’ve found hundreds. Now our map isn’t precise enough Number three: for The Dark Forest to be correct you have to assume that every living being and of every current species reacts the same way.

The uncanny valley is because of other human subspecies that we needed to be aware of and also that we would have a genetic imperative to avoid procreation with

This video sure ended suddenly, didn't it?

Solipsism doesn't go far enough. Just because i think i exist, doesn't mean I do.

Aren't we zooming through space at untold speed. That message saying where we are is where we were isn't it.

Ever see Bird Box? Scariest thought I had is what if the afterlife is so amazing compared to earth life, and there's no hell, and if looking at the sun gives you the "Devine truth" then that movie represents what could happen if that was indeed true.

You'd think that having a gameplay background with an AI voice reading pre written comments from fucking reddit would be easy enough, but NO! YOU DIDN'T EVEN BOTHER CHECKING THE FUCKING SUBTITLES. WTF IS A DARK FORCE THEORY???? IT'S DARK FOREST MY MAN

The backstory in EVE online is the concept that all the player characters are functionally immortal. If they die a new body will be made instantly and the consciousness redownloaded. It is a fundamental advantage but that original you does have to die in the process. Would you sacrifice yourself to let your future self never fear death? How much do you care about “you”?

The scariest theory for me is that all this time we all live in a simulation and that everything is all just a lie, snd we'll waje up once we die, just like that dude who stared at the lamp on the corner of his house.. something like that 😅

I had a weird theory one day that just randomly came to me. If the Universe is so absurdly large and theoretically infinite, then that means all possibilities could exist, which means, somewhere out there, humans exist. Exactly like us, just on a different planet. If the universe is infinite, statistically, this has to be true. It's weird to think about especially because, the human mind just cannot comprehend how vast our universe is. You might be like "Yeah, it's big" but to fully understand the actual scale is not possible. So not only are there other humans out there, they could also exist on multiple planets, not just Earth and one other, theoretically, there are more.

As someone who lives in the UK, the alert one wasn't boring at all. It does feel like we're at the brink of nuclear war every passing day.

Is there a story that correlates to the thumbnail? That looks awesome! 😅

There’s a pretty good chance we’re the precursor race that starts messing with things out in the universe because we’re that technologically advanced.

3:40 Story 7 Uncanny Valley Their theory doesn't make sense to me because even though we die, we are still human. We don't become non-human just because we died! We still mourn and bury, and love our fellow humans who have passed. I think the reason we have this sense is because we used to live on earth WITH OTHER humanoids! It would have been imperative for us to know human from non-human! Imagine going through the forest and you come across someone but then your senses start to go off and you realize they aren't human like you. They are one of the other people-like tribes that live around the land. You will need to know or figure out how to interact with them so you can make it back to your own tribe.

The vacuum one is inaccurate. We wouldn't see it coming if it was going the speed of light lol... If we "see" it, it's already here.

MY ENTIRE LIFE HAS FELT LIKE STORY 8. YET I HAVE NEVER BEEN INTRODUCED TO THAT THEORY. IS THAT PERSONAL OR IS THERE SOMEWHERE ELSE I CAN FURTHER STUDY THAT THEORY. PLEASE RESPOND

I think the scary one is money.

Life exists naturally around purple stars. The anode glow blocks out radio signals. We’re screaming out into the void to people who can’t hear us.

the third one, solipsism, once you get hit in the face with a punch you get a reality check and get to know other people are indeed real... and pretty dangerous.

That man's understanding has utterly failed him regarding this world

Simulation Hypothesis Story 8. There is no way to prove or disprove this is or is not happening. I and others do not believe it is because why then would we be allowed to continue thinking it was a simulation? Anyone actually running a simulation we would be in has every reason to make sure we never come to that conclusion. Because thinking that way changes how we act. As was demonstrated by OP in Story 8 wanting people to not have kids because they believed this was a simulation. That act is dangerous as it would soon end the simulation with a high likelyhood of ending it prematurely. In which case those who ran it would have to start all over again. Also if you know it is a simulation, then there is a chance you could learn how to game it. As a simulation it would have absolute rules on everything and not just physics. Figuring out those rules would allow you to alter, irrevocably, the end result of the simulation. And as a simulation it would have been simple for the program running it to simply not allow anyone to ever think they are in a simulation, or just delete that thought as soon as it happened. And anything as wide spread as this hypothesis is right now could not be missed. So I don't believe we are in a simulation.

5:56 it shows how Liberal Democracy has failed and that we need to return to tradition

If the hadron collider in Europe forms of black hole, and we all get sucked in it😂

If you were gonna believe in God for the reason that you stand to gain eternal happiness or lose nothing, then you better star trying to create Roskoe's Basilisk.

story 10 is terrifying if you understand the implications behind it. basically history will repeat itself. these ultra conservative or ultra traditionalist religions will be the dominant population as the birthrates continue to shift and sooner or later they will either force anyone outside of them to join or be wiped out. it will also likely lead to wars not seen since the roman periods as the remaining factions fight over whos god is right. the terrifying implications of this start when you understand just how willing these groups are to do great evil- in the name of ultimate good. men will enthusiastically do the most evil and cruel things that can possible be done to another- if they think their divine savor demands it, or benefits from it.

The thing with quark stars is that they are something that "could" exist, it is theoretically possible but we have not found one so far, for now it is a hypothetical object, now imagine it colliding with another quark star, for now it is unlikely, so we're fine

I’m pretty sure the strange matter theory is a bit wrong. If I remember correctly, strange matter is a type of theoretical matter that is perfectly stable. The reason it is infectious to other matter is because it will convert that matter into a stable form which completely changes whatever it comes into contact with.

The end of story 8 was personal bro Lmao He basically ended the story with “I hope you never reproduce.” 💀

The beaming of radio signals covers MAYBE 0.1% the length of our Milky Way before dissipating. Radio signals is a stupid waste of time.

That last one is excelerationism, or Warhammer.

I think Story 7 is dealing more with fear of Neanderthals

In H.P Lovecraft's story "The Shadow out of time" the great race of yith are capable of swapping bodies with creatures/beings from the past or future, different planets and other dimensions. They avoid extinction by finding suitable bodies from a different time period/planet/dimension and switching minds en masse. A whole race's bodies stolen as they are condemned to extinction while the Yithians escape to continue their existence. We like to think of time travel in very simple terms, I, unaltered and complete can travel through time but what if it were more like the above example?

Disagree with the “don’t add to this world with children” On the contrary, have as many children as you can, for this is good.

*Fermi Paradox* Closes video with tired eyes.
