Is your future already written? Do your past, present, and future all exist right now? Surprisingly, the answer could be yes.
Let's take a look at what time is and how it works - in our first video of the year!

I'd like to keep my free will if possible!
@@J.5.M. If quantum particles behave randomly and their behaviour cant be predicted because of that, then that means the universe isnt deterministic. But that doesnt give humans free will. The future is then dependent on what quantum particles do, and there is no "human will" involved with how these particles behave.
@@user-oq6sc3yz3l Dang, that's a good point
@@user-oq6sc3yz3l if a "humans free will" is determined by what quantum particles do, what determines what quantum particles do? BTW, where did the physical laws of the universe exist prior to the big bang? Where did the matter or "ingredients" to create the universe come from if the laws of physics deny the creation of matter in a closed system (the universe)... Is zero the presence of nothing or the absence of something?... What shirt will I wear tomorrow? What will the price of Silver do overnight? Will Earth be hit by a Gamma Ray Blast? Is it good to be comfortable with uncertainty instead of being a dogmatic narrow minded moron?..........
The idea that the universe is creating "new" time (or that new time is being created by something else) is actually freakier to me than a deterministic universe for some reason.
Something I said in middle school: “you can’t change the future because changing the future was already a part of the future.”

Gotta respect the platypus, after all, I do believe it is the only mammal that lays eggs and doesn't give birth to a live platypus. Not that other mammals give birth to live platypuses, platypae? Not sure which is correct in the plural sense, but anyways, I only meant they don't give birth to live young like other mammals. I think they're kind of cool.

I'm actually about to miss the bus from watching this video
update I made it to the bus on time
@@user-qh1br4ik8y lol i watched this inside the school bus
and didn't miss the bus.... all "nows" that were valid. excellent point. totally didnt pick up on that.
this video is about false understanding of relativity and a total nonsense. an alien 1 is actually in the past and an alien 2 is actually in the future. there's no 'different' 'alternative' 'nows'. 'internal' aka object times 'move' differently depending on relative speed, objects don't have different nows. this video is a pseudo-scientific joke. it is actually harmful just like flat-earthers' believes.
Its an apt analogy. The physical processes in our brains that create consciousness happen FAR to slowly to be measured in planck time. Meaning consciousness lags behind the "current painting" because our minds are nowhere near fast enough to perceive each frame. Consciousness has "missed the bus"
The past doesn’t exist, the present is the past, the future is the present.

I've always thought of time in the same way as a book. The story exists from beginning to end within the pages. But we can only experience it one word at a time in the same way we can only experience time itself one second at a time. An unread book holds surprise and the unknown, but the beginning, middle, end, and everything in between already exist. We see our lives as having a beginning, middle, and end, but we really have no way of knowing where our "blink and you missed it" existence is in the bigger picture of beginning, middle, and end. I guess skipping ahead and reading the ending would equate to time travel in this analogy, but only a complete a-hole would do that.
So it's all predetermined?
@@jinfin221 Yeah if you believe the block universe, the book analogy is just another way of explaining it. Skipping ahead in the book would kinda equate to just moving very fast in the block universe.

even though i dont understand yes
It sounds like the problem with the 3 alien spaceships thought experiment is that the "instantaneous internet" breaks causality in the same way that time travel would.
Yeah, I don't see how that thing implies there is any problem. Such communication is impossible for a reason.
Well there's what Einstein called 'spooky action at a distance' (quantum entanglement), so _theoretically_ it might be possible despite breaking causality. But I'm not smart enough to understand it properly, so please don't take my word for it.
Time travel, or also maybe knowing the exact position and momentum of a quantum object. Sort of breaks the rules.
In the sense of communication, sure.
But what it does is more clearly illustrate something that we do know to be true, that your time frame is determined by motion through spacetime.
And this we have observed through our GPS satellites gaining about 38.6 microseconds every day compared to clocks on the ground, due to time dilation.
Though I personally don't think faster than light communication or time, travel necessarily needs to break causality, in the same way one could draw a flipbook involving a time traveling character.
Essentially, the character would need to do something unrelated to the events on the previous panels, say they do something different in the background unnoticed to the foreground characters, thus not influencing them. (Unused information)
Or do something that fulfills the events of previous panels. (Information that was there from the beginning anyway)
In both cases there is no violation of causality.
Came here to say this. While it illustrates how time changes as you move faster, it ignores that each of those six points in spacetime have completely different presents, and wouldn't be able to interact.
Not even through spooky action at a distance (unless you really like pointless guessing games that cannot be used for communication).
I watched this video 20 years ago n still love it
I've been trying to explain this to people and nobody understands. Thanks, guys.
"Don't Hug Me I'm Scared" reference caught me off guard 😂😂
i still have PTSD of that clock
The past is far behind us the future doesn’t exist
what's the time?
Its quarter to 9 @@SandroWalach
i almost screamed
When I was a kid, I thought a lot about the phrase "time flies when you're having fun". Like if I spent a whole day at school while my friend cut class and went to an amusement park, the day would feel significantly shorter for them because they're having a blast and I'm bored at school and time is dragging.
So, the day flies by for them, each hour feels like 20 minutes, meanwhile the day is dragging for me, each hour feels like 2. So, I thought to myself: "in their head, the day is probably already over for them, and they are getting ready for bed, meanwhile I still have an hour left of school. So, am I in the past? Is everyone's 'now' different? Has anyone thought of this before? Why is no one talking about this??"
And then I learned about the theory of relativity.
So basically, I'm Einstein.
Thank you for coming to my Ted Talk.
thanks sir, if your young version's hypothesis was true, I knew how I can stretch my time literally. 48 hours a day? How beautiful!
Well I’ll be damned, I had similar kinds of thoughts like that myself from time to time. Still do
Strange thing is I even saw a brief 1 second glimpse of my own future once too. Didn’t realise until years after I dreamed it but it was exactly just as I had seen it. I haven’t had any since but perhaps that will not always be the case.
Makes you wonder doesn’t it? Is the future set in stone and strange fluctuations in the fabric of spacetime allow some premonitions, was it a bubble in the fluid ‘present’ allowing a brief glimpse into a possible future?
Are dreams even fabrications of the mind, or are they windows into viewing possible moments in alternate realities and parallel universes. Who knows
Strangely enough yes i had this thought that time moves differently under certain conditions. Are we all in sync or do we all have a static amount of time that gets spent at different rates? Do too much of one type of thing using up time faster and reach the end of life sooner etc.
The way we experience time has a lot to do with our mental state. For sure time does not pass equally for every being in the universe. I don't know how old you are, but 5 years in our childhood seems to take a lot longer than 5 years when you are an adult for example.
I started feeling like that when I was 7
I came up with the basic theorea first. Love the content, plz make more
10 years and still this video is amazing.
"Most people think Time is like a river that flows swift and sure in one direction, but I have seen the face of Time, and I can tell you, they are wrong. Time is an ocean in a storm." - from Prince of Persia, the Sands of Time. Makes more sense to me now, after 21 years.

Episode number and series
@@syedzakariya4124
It was the episode that introduced Professor Paradox (Ben 10's parody of Doctor who).
All we experience is the now and the changing events it contains; the past consists of remembered events, and the future of imagined ones, both experienced in the now. Time, therefore, doesn't truly exist-it's a practical concept we've invented. There is no determinism, only the spontaneous unfolding of events. The freedom we experience isn't about making choices; it's about embracing the flow of spontaneous creation.
Time is definitely one of the most complicated, weird and difficult things that one could possibly try to wrap their head around, so Kurzgesagt attempting to simplify and teach it ''in a nutshell'' (Exactly what they do best) is definitely very daring and commendable.
[Edit 1 month later] wow has this comment gotten popular, why did I just now realise it's been saying ''Comlicated'' this whole time T~T
yes, true, and gave some existential dread in the process, and btw thanks quantum physics, for allowing us to keep our free will!
Agreed, especially the fact that they've managed to discuss both determinism and uncertainty as literally opposing ideas in a single yet logically coherent video!
@@golamrasul9887I truly don’t say this to be argumentative, it’s a genuine question. Absent religious reasons, which I don’t think you’re getting at here (and I think/hope we can finally start to write off the opinions of the religious as an anchor on progress, they’ve been the loudest voice in the room and the legislatures, etc, for far too long), why do people cling to having free will so badly?
It’s not like once we discover or accept we do or don’t it changes. If we don’t then we never did and things would *seem* largely the same, except maybe we could be more compassionate. If we do then we always have.
Comlicated or complicated?

When I was facing hardship with my thesis I have always thought about this concept that past, present and future exist at the same time. So I would tell myself that I actually have completed my thesis.. so only thing left to do was to wait for that moment in the future from my perspective. Of course for this to work one has to be 100% sure that the task at hand will be completed one way or another.

The past is far behind us, the future doesnt exist!
never has the phrase "Except! Quantum stuff..." made me feel so relieved than at 5:38
surprised myself.
fr had me like: 🙂😐🤨🤔😦😗😅🙂
I hope you'll see that you don't need quantum stuff to know your mental process still exist, if that's the part you're afraid of. Like, you can agree that your "today" will eventually be your past, and that for that futur you, it has already happend, and they know which choice was made. But it doesn't change that there was a thought process, a decision, even when the output is already known.
Determinism or quantum randomness = No free will.
@@lucdombar4527 Thank you. Searched the comments just to find someone else that disagrees with Kurzgesagts interpretation of free will.
I hear it so often and had yet to hear someone question it, even though it seems so obvious that just because your decisions are fixed does not make you unable to make decisions. You just will always decide in the same way that the same version of you in the exact same situation would always decide.
@@riliash > You just will always decide in the same way that the same version of you in the exact same situation would always decide.
that's actually a really nice way to put it. Because of my past experiences and my neurology, I will make the same decision under a given set of circumstances, so despite then decision being fixed, the choice was mine after all :)
So interesting, I feel like my concept of time is memories I'm experiencing
Quantum physics doesn't say the particles are intrinsically random. It says we lack the instrumentation and a deterministic model to predict the movements, so we adopt a probabilistic model. A deterministic quantum model is never out of the question. This is a misunderstanding of key concepts, mainly because the topic needs to be simplified when it is communicated to a lay audience.
Yes, exactly! I was thinking of that, too, when taking in the concept of the quantum particles in the context of time and predictability.
These videos are the only thing that calms me down. It's nice to know how small my work problems are when im apart of such a large universe.
And on that bombshell, let's give a round of applause to the feeling of an existential crisis, the very thing that Kurzgesagt does best.
Right?!? I’ve never gotten an existential crisis from their videos 😭 it’s only ever calmed me down
Indeed! Relativizing is the key of self-regulation and emotional intelligence!
Except theyre not small for you, only for the universe. And who gives a shit about the universe because it is us who have to deal with the 'small' problems
Well said
“The conception of “time travel” is predicated upon the notion that the future has already occurred and that the past is somehow still accessible, which begs the question, where is time being “saved”, and what IS “time” if not a mere abstraction?”
Very true.
The only reason I give any credence to the theory though is bc time travel is indeed possible.
So if you can travel through time then perhaps that point in time before or after your own exist at the present. Otherwise, idk how the past or future could be accessible
@@mattchambers4561 it’s quite intriguing
Time is the meaning of existed or proof that something actually happened or was created ,time is the past
I believe traveling foward in time is completely doable. But you could only see the past from a distance and never actually experience it.
Both aren’t possible
great job explaining the 4th(time) dimension like a literal dimension in space
I watched this when I had a few to drink and got confused so watched when I was sober and was still confused. Anyway…. 10/10 video. I love it

Thank you for including paradot
Wow! It all makes sense now!!!
The idea of the Growing Block can be super inspirational. It should be a poster with it saying something like, "The Block is still growing, lay the story". Idk, but I would buy something inspirational and sciency
BRO!! I WAS JUST THINKING THAT!!! (You read my mind)
Great minds think alike! Yeah! I would totally buy a poster like that!
For me the ideal slogan would be:
The Block grows, with or without you, but only you get to decide how.
Stack your bricks, or someone else will stack theirs. 🧱
I don’t know, I think the Universe favors those who make the first choice, though I still strongly believe you have to think things through first, you can’t just keep worrying about the end result forever, either you’ll succeed or you’ll fail. Just learn from your mistakes and try again. It’s okay to fail, but at the end of the day Eventually you’ll have to make a choice.
We all have to take a stand at some point in our lives, if we don’t want the Universe to leave us behind.
Except that would be a lie. It would have to say something like "The block might still be growing, there is a possibility you could lay the story, maybe". Not very inspirational or sciency. Besides, the whole idea of democratizing time makes no sense, because it's still measuring it from the frame of a human like consciousness, if we include other things then time is just movement. If something moves slower then time moves slower, and if something moves faster than time moves faster. And at the extremes of both time ceases to exist, they are essentially outside of time at opposite ends of the spectrum, which suggests we're dealing with something circular that loops back on itself. And if we take all that into account then the block of ice is more likely, because the growing block is intrinsically tied to the flawed, subjective, and not scientifically understood, idea of what humans consider consciousness.
@@alirezaomrani7650What if it wasn’t a growing block yet a frozen cube already set in your way of you getting that poster and getting motivation to do something.
Yes! Also I wonder if in the distant future conscious beings will be able to "mine" the block we are creating...and resurrect us long after we are dead. If the block exists, shouldn't it be accessible given enough time and technological advancement? I find this idea super inspirational
What was the point of this comment? Just to daydream about buying a cheesy product?
Yay, now I can question my reality and not know for certain whether I really exist. Thanks Kurzgesagt! 🎉
Why, you couldn't do that before watching the video?
you'll get over it eventually
Existential crisis, achieved.
But you do know though, you don't need to understand it, life is nothing but a inexplicable miracle, yet you live every day, why not believe in it?

Amazing in fact
this video is about false understanding of relativity and a total nonsense. an alien 1 is actually in the past and an alien 2 is actually in the future. there's no 'different' 'alternative' 'nows'. 'internal' aka object times 'move' differently depending on relative speed, objects don't have different nows. this video is a pseudo-scientific joke. it is actually harmful just like flat-earthers' believes.

Not the refrence expected in a kurzgesagt video
Oh my god, I thought I was seeing things.
It scared me.
This is the second time they've referenced him. The first one was in the homeopathy video.
Wow! Im just amazed to see the development and the way knowledge is spreading in my own lifetime, something i couldn't even think of as a kid growing up! Thanks guys for this amazing video! 🙌🙏
The way I have always seen it, the big bang was like a bubble bursting. Everything happened all at once and it's already over. I think of that whenever I'm having a bad day and it cheers me up
Right now I'm 41 sitting in bed watching this. 30 years from now I can watch it again and it'll be my 71 year old now. And now I'll wonder at 41 what my 71 year old self is thinking and visa versa and this moment will be linked. And now I've gone cross eyed
One thing that helps the mental mapping of how there can be "so many nows" and also how some "nows" are in others' "future" is that there is a speed to causality.
Yea. Causality "spreads", at the speed of light... Which begs the question... in a sci-fi setting, could reality actually be rewritten? If a "causality wave" moves at the speed of light, would an "anti-causality wave" be able to cancel it impacting with the first, canceling the event retroactively?
Maybe not where the event already happened. What about canceling its spread... ?
What about the reversal of causality?
Can highly recommend Wolfram Physics - they have a whole theory where the universe is made out of causal events and nothing else
I was surprised this wasn’t brought up
@@sethheristal9561 Yes. Instead of thinking in terms of time and the speed of light. Think of reality in terms of MATTER and CAUSALITY - like dominos interacting with each other. Light moves at the speed of causality. And obviously when you move at the speed of light, YOU are moving at the speed of causality. But, you are moving at the speed of causality right now. Everything does. Your "particles" are currently whirring in orbits at the speed of causality. If you get in a spaceship and approach the speed of light, your particles move through the fabric of space, your causality is iterating through the fabric of space, slowing down the orbits of your particles because the speed of causality is constant, therefore it must be distributed between orbital and lateral motion. So, your orbital cells slow, and your thinking slows, but you are flying faster through space. So, stop thinking of it in terms of a clock. Think of it in terms of matter. Time is a tenuous concept that humans made up. A clock is just a spring under tension or an oscillating block of quartz anyway. Scientists have tried to track time accurately using cesium and found that the clocks diverge just by raising it off the floor. So how can you ever expect to track now? The concept of time understood by the general population is very primitive. We might as well believe we can "measure time" using ocean waves.
“Ok. This is a lot... Imagine three spaceships 1 million light years away... “
I’m more upset that they didn’t explore the most likely outcome of quantum effects: that each of those bubbles of now mesh via the Many Worlds / Everett interpretation in the universe branches like a fractal with bubbles intersecting and diverging in a mind breaking tapestry of reality. Determinism breaks down here in a model where everything that can happen at any given moment does happen in branching realities so the concept of frozen or growing block becomes meaningless.
@@Mach10Xthis isnt supposed to be that advanced
I appreciate you,@@Mach10X
I agree on this theory. That’s how you get déjavu. I had many personal experiences to support this theory. Like once i was driving early in the morning where the roads were quite empty, i was speeding on the speed lane and I somehow got distracted with some heavy thoughts. Suddenly something made me to cone back to reality and concentrate on the road and i slowed down a little bit. Few seconds later there was a flipped car right on my lane where an accident occurred. If I didn’t slow down i would have gotten into secondary accident which would have costed my life. Maybe in future which in this case i would have already gotten into an accident and i somehow felt it. Idk how to explain because I’m not a physicist. But i always had many theories and interest in this field.

Ah Kurzgesagt. Putting some of the grim realities of life in an engaging, relatable, clever, iconic, & ironic way, et al.🎭
To be clear, quantum mechanics might imply randomness, but there are equally valid theories of quantum mechanics that are completely compatible with a deterministic spacetime.
Theories that contends with quantum mechanics? It's the most accurate one based on observation
yeah. it pretty much all comes down to the fact that we as humans dont know shit
@@pumpkin_pants3828 It's not actually that complicated. The problem is most people don't typically spend their time conceptualizing what it would mean to exist within more than 4 dimensions. And just so you know, our Universe does possess more than 4 dimensions. It definitely has 5. Probably has more... but the limitations of our equipment kind of makes proving the existence of those dimensions beyond mathematics and theory almost impossible.
@@parlor3115I don't think they mean something other than QM. I think they mean other interpretations of QM. As they said, "equally valid theories of Quantum Mechanics".
A point of clarity, Quantum Mechanics isn't the name of the theory. It's what we call practicing physics at the Quantum level. There are several valid theories on how Quantum Mechanics work, like the Copenhagen interpretation, or Superdeterminism.
You people in the comment sections aren't experts. Everyone in this thread is just a windbag typing bs
I wish to add that: even if time is already written (and even with quantum mechanics it's simply random not 'free will') it simply means that, in exactly the same situation, and as that exact version of us, we will always make that same decision, but even if that event will always happen and the outcome will always be the same it is still our own decision, our brains deciding the course of action to take, which (if you don't believe in anything beyond reality like souls) is all that would happen anyway. Essentially, the predetermined future is simply a projection of the decisions you will make, it doesn't nullify that you have made them, it just the when of the matter that's blurry.
It's the same as how if you ask a computer to determine which of two options are better it will always arrive at the same conclusion if you give it the same starting data. The calculations the computer went through to arrive at this conclusion aren't worthless just because it always arrives at the same one, they were still necessary and useful. If you view free will as more similar to this situation, basically an evolutionary adaptation that allowed us to handle difficult and novel situations by being able to think freely and abstractly, then it still clearly exists. And like there's no reason to treat free will as somehow special and different from all our other evolutionary adaptations since we aren't in any way seperate from the rest of life on this planet.
@@hedgehog3180 Exactly!
Well said
One more thing to add is that this is less time travel, and more just going to the future faster and irreversibly. You're just seeing the future world faster, and finding out what happens later. You didn't go to the future, your now just progressed sooner. Your friend's decision isn't eternally locked in stone when you go forwards in time, it's just you remeet them again years later to find out what choices they made.
@@hedgehog3180 You're correct about algorithms in a computer generating consistent results. However, my choices are ad hoc in comparison. Grab the can of Coke or the can of root beer from the fridge? My choice, on a whim. Unpredictable.
This video reminds of my two favorite books about time. "Laminated Spacetime" by: Barbara Dewey and "The Arrow of Time" by: Covey and Highfield.
The saving grace for anyone having an existential crisis is that by the time you could communicate with anyone whose 'now' sees your future, you would already have reached that future and nothing weird actually happens. I guess a useful analogy is to look at different projections for world maps: They all look different, stretching and warping different bits of it, but they also all tell the same coherent story.

What I find so fascinating about relativity is the sheer amount of time travelling paradoxes you can create, and how some of those same paradoxes might interact with each other
I think the universe prevents paradoxes.
Time could very well exist in these blocks, but when quantum mechanics comes into play, prior to the collapse of the wavefunction by an observation, the universe splits into the many worlds.
Perhaps t=0 was a single page, but for every plank-time after t=0 there would be an exceptionally large number of pages to represent each of the possible universes.
To break out of science and into my personal philosophical and spiritual beliefs - there is an untestable but fundamental analog of the fundamental quantum fields, this analog upholds consciousness-exclusive information like qualia for example.
I think the overall consciousness-field is literally in-and-of-itself conscious and capable of universal scale choices. I think that consciousness-field (which I consider as deity-like) is the universal child - but he's not drawing the pages, he's picking which pages go into the book (or books if time travel were to become possible).
The consciousness-field exists across time from the big bang to "Prime-Time," which would be defined as the time in which no conscious observer has yet born witness to collapse the wavefunctions.
@@JaydragonMThe universe doesn’t prevent paradoxes. Paradoxes are just the maths way of telling you you got things wrong in some way.
@@mzaitealthough this isn’t really a paradox assuming that light travels at the same speed both directions which is always assumed when talking about the theory of relativity
Floatheadphysics has a great video on the andromeda paradox which is what this is and explains why it isn’t a paradox at all
@@Parxi_o incorrect. Light can only move up at a 45 degree angle relative to where it starts. It’s fixed.

I think personally, due to relativity principle, you can say that YOUR "now" is valid, so does your future and past.
But, because this is YOURS, meaning while you expirience it, the you of the present is feeling both the future and past, while other, with their own relative perspectives, can only "know" one of the "nows" of yours, as the same time like the expample shows, the time diffirences while you travel from one point to another in the block of time.
Wasn’t expecting to see my boys Kirby and Bandana in this video. Love them!!! ❤️
this stumped my understanding. like what the hell? your guy's ability to explain overly complex notions are laudable! every time you guys introduced a model of time of the universe, it always made me question stuff like "is the future already written then?!" and you guys actually do cover it afterwards. predicting the stream of human consciousness is a godlike skill so I applaud y'all once again! now i'm going to debate the paradoxical contradictions between the ice block model and the growing block model lol because either don't complement each other at all...crazy stuff...
They don't really predict your stream of consciousness, i'd say it's just a question that naturally arises when a human being thinks of the topic, it's more our reality that constrains your stream of consciousness than Kurzgesagt that predicts a specific branch.
You're just too naive and straightforward at the topic. There's more paradoxes arises. Just not so long ago, in 2023 scientists proved that photon can change its properties because of its future pathway. Its been called time interferance. The research is named "Time slit experiment"

2:00 thats what i was thinking, like when someone goes to sleep they probably are experiencing the next day while you are still trying to go to sleep
Whenever I watched time travel movies and read books on the matter, I always wondered how things unfold the same way in the past when someone has time traveled in the past and things change only if they disrupt the events. In my mind, I always thought that all the past, present and future events are taking place on same time. One person doesn't go "back in time", they simply go to that another dimension where things are happening, just like the present. This very moment, Mars has colonies of humans in 2100 and this very moment World War 2 is taking place in 1942. I am glad that the theory that I had in mind had been discussed here.

You know THERE has to be one Absolute Truth/ Objective Reality (100%)
[regardless of what different scientists, ph.ds, doctors, philosophers, societies, religions, cultures, individuals, etcetera believe].
The rest could be categorised as either -
1.) Some Truth with some Falsehood mixed in it (no matter in what ratio/ percentage it is in) or
2.) Complete Falsehood/ Delusion (100% Wrong).
Its something like this -
[If Analogy is to be used our Body is like a Hardware of the Computer and our Soul is like a Software. Just as Computer's Hardware is Useless without a Software, similarly, a Body is also Useless /Lifeless without a Soul.]
We go through 5 Phases in our Life :-
1. The Realm (outside of this material Universe) where we took an oath & chose to be granted free will and want to be get Tested (The Testimony of believing in Only One God by our soul),
2. In our mother's womb (9 months) - The soul is breathed into the body, which gets created from a single molecule through a unique DNA🧬 (An Instruction Manual/ A Program/ Code) fashioned/ programmed by Creator. And, as the soul enters a body that's from where our consciousness and conscience comes (it happens with a lightning speed i.e. in a fraction of a second which Scientists/ Doctors couldn't able to capture it),
3. On Earth 🌎 (On an average of about 60-70 years)
[Commencement of Test with the Development of Conscience],
4. In the Grave (The time frame from our death till the Day of Judgment/ Resurrection) &
5. In Paradise or Hell (Eternal Life).
All are Temporary except after the Resurrection. So, the consciousness in brain 🧠 gets activated when soul enters the body & through soul the conscience (sense of right and wrong) of heart gets activated (including feelings like joy, peace, pain, anger, etc.).
They just don't want to be responsible for your "intentional premature exit from life", brought on by your realization that you are, for all intents and purposes less than a speck of dust. So they tell you it will be okay. Even though that changes nothing.
