That guy was the BEST lecturer at Sheffield! Shout out to Primer too, what a film!
I am indian
I tried to pretend i understand what he's talking about
Actually, this is common sense material. not rocket science.
U got me
He is pretty much talking aloud of shit to explain a paradox which makes no sense by using math? You think he's talking smart but he's not
Like the only bit that actually makes sense is the end.
Edit: not the skit the quantum mechanics it makes more sense than Marty mcfly mechanics
aaron bonnes exactly. I’m not even a mathematical person and I can see that.
George Khumalo Really? Please do explain. How can you be dead, not even born in the first place rather, and time travel? I’m not a scientist, I’m not even a mathematical person, but this is absolute bullshit. A trench digger could see that...
What do we want? Time travel! When do we want it? It's irrelevant! :)

Tony stark: sHiT
He said make it in a Möbius strip with a certain Eigen value. Which is real.
What about parallel time lines or universes. When you go back in time and change something in your base timeline's history, you are initiating a parallel timeline that runs concurrent with your base timeline. In your base timeline, you still exist and so does your grandfather, but you're missing because you left it to go time traveling. In the parallel timeline, your grandfather is dead and your past self is never born, but you are still alive because you originated from a separate timeline. I think this is what you are referring to as "superposition" at 4:17, which is normal stuff in quantum mechanics.
you look so happy in ur pic ur kinnda like santa but with a mush stash

Rick Miranda absolutely.
Anyone notice that the coffee spilt in a triangle shape. Illuminati confirmed
M S how the fuck does brewed coffee split?
I notice the same.
This is the first thing I noticed! Wired ya?!
You must have time traveled from 2012
Have you heard of coincidence?
Literally spilled coffee on myself thirty minutes before watching this video. Now I'll spend the rest of the day pondering the implications...
Mathematics allow travel in both directions. But going to the future would be a LOT easier than traveling to the past. We travel through time everyday. At a rate of 1 second per second, we move forward through time in a forward direction. However, the faster you move, the more time slows down for you. Time is relative.
If it's easier to go forward then we need to figure out how to go backwards.
At the age of 13, I traveled in time twice with the help of two adults.
First for the past and second for the future.
What he says is not true.
"Time is relative" explains duration one, but duration two, a neighbouring temporal dimension allows natural timeslips.
you can travel forward in time because it has 0 effect on any existing thing. traveling back in time is the difficult one
Yes. All you need to do is escape gravity, whether that be far away from a gravitational object, or by using velocity. After a year or 2, a clock on top of mount Everest will be ahead of a clock at sea level. But only by a microsecond. Time travel !

Not actually speed back would be easy....... U would understand better of it if u would read theory of relativity
BTW we are time traveling now this minute and this second
What if there is a no future? I mean what if tomorrow a big astreoid destroy the world? We cant know future. So we cant move there.
If you eliminate time and instead assume that only entropy acts upon you, you also eliminate paradox's. Time becomes a singular moment, things are created, destroy other things to survive and entropy acts upon all things eventually destroying them. The air you breath is the same air your grandfather breathed. Mind = Blown!

My 3rd-year physics lecturer, Dr Pieter Kok, His advance electromagnetism course is too hard. Luckily I passed and graduated! 2015 alumi here
The last scene gives me chill men..
That was 7 years ago.
The very fact that you exist to travel back in time means that a paradox will never happen. The gun won't fire, you'll run out of gas, you'll change your mind. You can not change anything in the past that stops you from entering the time machine. Because it HAS happened it WILL happen. You can only cause ripples in the stream of time, you can't change the stream's course. I know, I tried.
Julian Wells Where is the evidence of you trying?
What about additional realities? Once the phenomenon of you going back, how ever you go back, a new timeline starts or reality. Not a infinity amount of realities just some. I call it flash point. 2 realities existing at once along side eachother. Diff vibrations and particles arranged diff. CERN and quantum computers are using or looking into what I'm saying.

Sangen Rai yes unfortunately
Also surprised how many smart people keep forgetting that going back in time and changing the course of an ancestors history even slightly would usually mean they would not have their exact kids in the exact same moment (conception) meaning it would be a different sperm and egg, meaning not the “you” - meaning you still didn’t exist. Back to the future seems to think Marty’s parents would always have the same number of kids and exact kids at the exact time
I'm so glad that all the children that I make on this Earth will be alive for a thousand years on this day
I was thinking it may be impossible, but if you are in a slower (clock), near C velocity, and also traveling slightly backwards in time, you would have more or less a FTL travel solution. Globally you would be FTL, and it would seem to have happened faster to the traveller.
Why don't they teach this in school I would have been so invested 😩
As you've said, the time travel movies get their physics wrong...
What about the show Doctor Who? Did they get the physics of time right when it comes to paradoxes?
time isn't a thing, it's just a measurement of the changes to matter. you can't undo what's been done, you'd think smart people would be able to figure this out.
true, but there is something that we don't know...let's think about it.
No hints. You are wrong!
That’s not true. Quantum physics and Einstein’s time dilation in relativity clearly shows time being stretched and warped, meaning it is possible to time travel.
You are right but 1000 years back, man wouldn't have thought of talking with someone face to face who is 1000 miles away.
Similarly today we don't know, what our future is gonna be like, may be we'll discover some new stuff called time machine.
Today we think time is a measurement but what if it turns out to be totally different?
This would be a fine way to see time, and would close debate, if only it wasn't for the block universe. See the block universe states that time, space and all other dimensions all coexist inside of the block, which is what we think of as the universe. Meaning that down to the atomic level, changes can occur such as photons splitting into different realities as we have no idea what is happening when we don't observe it, basically we have no idea how to disprove the multi-reality theory.
This means that a literal infinite number of timelines / realities can exist inside the universe and that all time coexists as well, you could call it "seconds" or "fractions of seconds" but really time is smooth and basically uncountable, but that also means that all time is equally as real as the last. Hence why the actions of the past effect the present and the future all at once. Also could be why time effects the universe and biological life in so many ways, another odd example is how when you take a video or photo that moment / moments of time is now recorded and you can go back and observe it at any time.
Another interesting thought is that the main theory of using travel into the past being a wormhole, say a wormhole between point A. (5257 A.D, earth) and point B. (2020 A.D, earth) exists, atoms would basically always be moving in and out of the wormhole for eternity, meaning that atoms are literally time traveling at a constant uncontrollable rate. Meaning that time, is basically a place as well.
I want to pose a scenario and ask a question. First, the question(2), is there rotation inside a wormhole? Second, if so, can a counter rotation stall the effect enough to allow forward travel by a means of propulsion?
Now for the scenario: a cigar shaped spacecraft is connected to a wide, circular band around- the band is connected with gears that allow rotation while the spacecraft remains upright and straight. The ship's rotaion field is positive, while the wormhole rotation is negative, thus acting against one another as in the field of opposite magnets. The ship, propelled by hydro-fusion and lithium crystals, is able to move forward and mimimize distortion.
What does anyone think? Does it sound interesting to you?
Yes very interesting nice thinking
The wormhole is a portal to another dimension 🤫
There could be zillions of "parallel universes" because zillions of scenarios could happen!
I needed this.
Another comment I would like to address: Past few years I notice because I mark calendar everyday.....we have been skipping days especially around the. 3 day holidays.....watch Thanksgiving this year.....clock runs fast around 12:00 a.m. to 5:00 a.m.
Hi please help me I want to go back and change my past please help me bro 🙏🙏🙏🙏😭😭😭😭😭 please reply me because my life very sad please help me 🙏🙏🙏😭😭😭😭
you take one object and another, remove the space between them to bring the objects close instead of a straight line to the object. cut the middle and connecting the first part to the end removing the middle.
Time Travel Rules I set for myself
1. Don't change history only observe
2. Wear chothes from that time period
3. Only spend 5 mins in the past to prevent any mistakes that would change history
4. If history is changed by mistake travel back and change it back 😎😇👍🚀
Alex Wood are you a time traveller?? Did you travelled through time ??
I created and traveled through a wormhole.Its really not that complicated once you know the basics.All you have to do is be able to manipulate space by pushing and pulling on it. Pull hard enough on a single point you open up a hole into the middle realm. (The space in between two dimensions ).That is when charged particles/exotic matter gets released which carries the energy to construct and power the wormhole.The charged particles look and move like sand being blown across the road.Then all you need is to accelerate fast enough by being able to skip space. I did it by pulling back on the space enough to collapse it onto itself.Once you have the forward momentum and your pulling back the space as hard as you can a vortex forms using the released particles and they will begin to emit a purple light.Now you have a worm hold. It is not hollow however, it is being built as you are traveling through it. So all you can see looking forward would be a particle dust storm inside of a dusty cylinder rotating clock wise.. I traveled forward in time with the one i had created. Only problem is after a couple of seconds looking around i was sucked back to to a similar time at which i had left but a different location from where i entered the worm hole. maybe about 3 miles ahead.But everything looked the same which ui then realised that every ones reality is based off of their own perspectives.So i am the first man to ever create an actual wormhole, travel faster the the speed of light, time travel and could manipulate time and space.And no one was there to see it, i don't think. If anyone saw me open up the wormhole in littlerock ca a little over a year or 2 ago let me no. i was driving a tan hyundai sonata 2012. I'm sure edwards afb has proof of the different things that i could do in that car. But i'm sure it would be considered top secret by now. Like teleporting off of a runway into the desert.
Woah. This is so beyond amazing and interesting please explain more I want to try it out myself
But how exactly? Make hole normally? Where? On a wall? Then I'll see a light illuminating? I have to run through it?
How to calculate, how much energy do i need to travel 100 years back in time?
How to calculate the exact position of earth at a particular time in this universe, as whole milkyway is moving, our solar system is also moving and our earth is also moving and who knows our whole universe is also moving or expanding and it's actual behavior.
Good question I also had that thought
Thank you Dr.Pieter Kok sir.
The past , present and future happen in one blink of time so is one !! We separated the time to describe event in space ... So there for the past is just memories, the future is the prediction of movement in space ,, the present is just energy quartz !! We can only slow down the time , but never travel in any point of it couse we are part of it self ...
Who knows how we can be reasonably certain that time travel into the past will NEVER BE POSSIBLE in the future? There is no technical reason,, just a factual one.. Sometimes a simple observation is all you need.
The simple observation of space-time allows us to see different times in space when looking at stars. Duration one is time relative to you & duration two is a neighbouring temporal dimension that allows natural timeslips so, time travel is possible.
Paradoxes don't exsist by the very nature of what a paradox is.
an easy explaination to the grandfather paradox is that you live in a different time period from when you kill your grandfather and with the picture it wont change because you got it from a tie period when they were alive
What would the effects on the body be? Would the traveling body revert back to a baby? A cell?? Star dust??? Would an item be broken back down to it's particals????
I have a general idea of predetermined paradox. That is the probability of an event is always fixed and even if we try to change it, it will result in the same as before.
Wonderful.when can l go back?
Dr strange,avengers endgame (the movies) : am i a joke to you
The simple and definitive answer to
the question of “Human Time Travel” is this; we haven’t therefore we never
will. This assertion is not based upon astrophysics or quantum physics but
rather simple deductive reasoning. Consider the following; if there were a
point in the future where time travel became possible, it would of course be
highly guarded to ensure it would not be misused (an oxymoron) by an individual
or government. Much was the objective at the advent of nuclear weapons,
however, time being the great equalizer, in just 74 years nuclear proliferation
has created the very real possibility that left to its own demise, humanity
will experience a nuclear holocaust. As with any major discovery, be it the
combustion engine, flight, PC’s, cellular phones or nuclear weapons, no matter
how astonishing it is initially, in time it becomes common and accessible.
Thus, if human time travel were ever possible, given our propensity to misuse
power, humanity from its conception through today, would be in TOTAL disarray
and PERPETUALLY in-flux. We are not, and there- in lays the proof that human
time travel will never happen. Humanity has shown that it simply is incapable
of possessing such awesome power responsibly and as such, time will forever
remain in the realm of an omniscient God.
Jeff Bailey Great comments Jeff. We as a species are incapable of possessing that kind of power. I liked your comment on nuclear weapons too. Sooner or later, and I hope it’s not in my lifetime, some idiot is going to use them.
In terms of time and spatial distortion, cobsider the movie starring Angelina Jolie, where she and her cohorts shoot bullets that twist and turn, around and past objects to only hit their intended target. That is distorted fabric!
Perhaps flux really does exist; (Dragon Riders of Pern-Anne McCaffery). When a person leaves the hold, a village, they enter the space called flux. It is a fog that wobbles, and shifts in its own space-fabric. Maybe, in this flux immediate movement is possible with just a sliver of exertion, and in so doing, one travels to a far away place in a nanosecond. Just some thoughts for you.
Dang all these comments are filled with smart people. Oof. I do Not belong herr
But God isn't real fucking real either.
I was working on something like this in my past life as a professor at Princeton University until in April 18 I died, and was reborn on may 21 , as this incarnation
One question, when a person travel through time why does the observer sees that he went for a split of seconds while the traveler experience full time
Dr. Pieter Kok You didn't do any experiment to come up with these conclusions You just reiterated what someone had already said And your understanding of quantum mechanics is absolutely saddening poor But unlike myself I have already established a connection with the understanding of how it really works And have already solved this time travel delima !!! 🙂🙂🙂
Share the results?
I will share some things but not others You go back in time And you carry out some kind of an action to try and influence your future What ends up happening is that (what they all fail to understand is that Yesterday can never catch-up to today And as of course Today can never catch-up to tomorrow) This is a scientific fact And what ever you did yesterday (in the past dimension) Stays in the past dimension Because it can't catch-up to today So that you can benefit from the actions that you carried out (to try to help out your future self) But what you would need to do , infact have to do Is stay in that dimension And live out that benefit that you seeded there (that action that you did) Hence there are no such things as paradoxes But there are multiverses It is just that these multiverses don't run side by side (parallel to each other) But they run back to back Chronologically with each other Hence yesterday , today , and tomorrow !!! And as for time travel This poor gentlemen has done nothing towards his oun education (educating himself in the laws of temporal and or quantum mechanics) Time travel has to do with effecting dimensions All he spoke about was of his diagram of nothing (You inter , come in through somewhere , and then you exit through somewhere else) ??? What does that mean When people experience de-javu it is because either they have crossed the path of someone else That has or has currently done a quantum mechanical act And or they are doing this behavior in their lives That is or has caused this event to occur (happen , become reality) A person can time travel (effect a dimension) simply by , or with , their daily behavior activity !!! And I can't say more than this And I can't believe that this know-ed gentlemen did not know this Or does not know this ??? This puzzles me Apparently this man is just a learn-ned subject (book smart) And not a real experimenting type of a scientist Like my self !!! And this is all I can say 😔😔😔 This saddens me That these types of people can voice their opinions And not know what they are talking about And just by doing this They influence countless numbers of students And miss-lead them in directions , that go nowhere But just dead ends They just miss-inform the public about science that they know nothing about !!! 😔😔😔
Interesting u should make a yt channel ur self maybe? If u wanna teach people the right things
If i was traveling at 88 miles per hour and got struck by lightening in just the right instance, would it make a difference if my vehicle was not a Delorean?
“You are dead right from the start.” Yep, knew it lol
What if parallel universes like ours are either set in the past or in the future?🤔
That explains the looping present .
The walking down the hallway did it for me 😂
In order to understand.
You need to look at all time machines invented and see which one is theoretically doable ..
I settled on the Wells machine.
I divided it into three stages of work .
The disk / the Leyden jars/ the accelerometer.
The disk I got spinning on its own and generating lightening.
The disk needed to be rewired so I rewound time .
I find it very odd nobody tried to fix the Wells time machine.... so I decided to see if it actually works at one time .
When the disk spins ... it forms energy at the Center of the disk ..
So the solution to the problem is the multiverse!? . This raises more questions than what we started with at the beginning of the lecture!? You have to love Science!
Hey...what about we go back to the time in the form of thoughts or through mind...where we can experience the past, visually see the moments and events but we can't change anything...why we have so much dependency on transporting physical body...our thoughts are quantum form ... vibrations are quantum... can't be assume that as vehicle first....then maybe body at later stage
This is why I love quantum mechanics.
Hello, I am just a normal person and I want to questioning this to you.
lets say, you are a creator/scientist who succeed in the making of the time machine to travel between times, and suddenly you travel into the past, to kill your younger self. so :
Alive = Y
Dead = X
Machine = Z (With a design that you can see the records of people who can manage to travel back or later in the time) its more like [Save point/transmit] so if other people manage to find the machine, they can see a records/history of people who are using it before and manage to travel on his/her last history location to repeat the sequence.
And for example Marty McFly playing guitar with a photograph of himself in the neck of the guitar, and its slowly fading out from the photograph because his parent are drifting apart. because there was no physical mechanism for this. (So i am assuming everything that are pure object or tools cannot disappeared or destroyed, even the times branching or even deleted. Because if we travel with the machine, the machine will stay put to where the last or beginning location triggered) [Lets say the machine looks like a pod that you always can go everywhere. with a fuel of course (There was an extra fuel inside the machine)]
Yes if there was a superposition we will stay dead, but we live
But in some theory if we change the past, it would change something in present as well.
What will happen if we kill our younger self in the past, and go back in the future? do it would change something? and after that if we travel in the present, but after we step on the ground (Future) suddenly we gone?
What will you said to solve this? is this becoming paradox? or? the branch of this timeline its self destroyed and do the machine still exist?
And this is gonna be something different and fiction:
Does the machine its self can manage repeat the sequence? Or it can verify its self that the branch of timeline had been destroyed?
You can not intervene past, can only observe. You can go future and intervene it but you can not go back to the where you came.
Yes there is a physical mechanism for a fading photograph that is linked via entanglement to its twin particle somewhere else in time and somewhere else in space. Once the twin particle is altered or disrupted in any way the entangled particles which would be the emulsion on the film that was exposed by the entangled light photon. Once the entanglement connection is broken the emulsion will turn black.
Can you please time travel and tell when will covid end.
I also want to know about it too.
Great explanation. But the ending 🔥🔥🔥.
There can be no paradoxes because there are infinite realities aka worldlines that can be crossed into going on based on what is changed.
What's scary is that I have no recollection of ever watching this video, but RUclips says that I already did...
The grandfather paradox seems incorrect. Rather i think time is defined in form of packets. Which inturn carries and object with task. Like space occupying object occuring a task in time ts.
Primer is his all-time favourite movie. Time travel expertise confirmed.
Who was the hero?
We have already done time travel but it is only in the past. Because we have to use light to see the past. Like if you see a quasar or anything in the sky. It takes time for that light to get here so that means we are seeing its past self not its present self and that technically it applies to everything because light is not instant because It takes time.
Tristan Taylor it means that you travelled to the past ??
Imagine that time travel has no traveling involved, that all time exists right here. Like tuning in a radio, rotating the dial counter clockwise to go back and clockwise to go to future. After all all time has already happened and like a phonograph needle the spot in time that we call now is the only reason why we are here. It’s all a dream anyway
I stopped believing as soon as he said Doctor KOK !
It's a Dutch name, it means cook :p
Haha, ok its still a little funny though..
I have never found anyone that can explain how the gravity part of this view keeps you tied to the earth. When I think of actual time travel happening, I always end up popping up in deep space after the earth has continued on in its orbit, leaving me behind. For once I would like to see someone explain how a person can be tied to the surface of the earth, so they don't end up in space, or above (or under) the ground due to the tilt of the planet as it changes through its seasons and travels in its orbit. I simply can't get past this happening, nor do I see anyone making any calculations to ensure that you are going to arrive at exactly the right time to have your feet planted solidly on the ground. I suppose that the fact that you would likely end up dead after materializing in deep space means that you wouldn't be killing your earlier self in any case.
Assuming you are standing upright. Time ticks slower at your feet than your head. Consequently in 4D spacetime you curve towards the earth. However no one knows why mass causes time to tick slower.
And what about the law of conservation of Energy/Mass. You pop up at the past out of nowhere but the mass/energy of universe has to remain constant.
Even the old heads - they talk of time travel like it sliced simple but it’s not. It’s still a one way trip no matter which direction, whatever identifier you used as your home thread changes the instant you leave because you hadn’t left yet. Even if you’re unlucky enough to get back a thread that hums close to your home one you’ll need buckets of meds to damp down the constant deja vu
I wouldn't say that I love Kok, but I respect this Kok and have no animosity towards those that do love Kok
There's no maths needed.
If time travel were possible it would always have been possible because it would have always existed.
It also means free will has never existed.
The only other possibility is that it's always existed and free will has never existed, but ... It's impossible to prove its use because all the things that have happened in your life are the result of the thing that was changed in the past and you're none the wiser. In other words, up until yesterday, you were The Queen, but something was changed in the past so now your history and memories are entirely different ... Let that marinade.
Travel forward in time. Travel a set mile and start at say 60 mph, then double it to 120mph, you’ve got there in half the time. Keep on doubling the speed until you nearly get there in a split second , then simply double your speed once more and a bit more to get there in no time at all. After that, The faster you go each time sends you further into the future. Ok it’s going to be quite fast which is beyond our technology but it’s an idea.
Time travel to an earlier point in spacetime is theoretically possible but it would logically require more energy than the Big Bang. Given that it would be possible to move all the particles in the universe back to an earlier point in time when everything in the universe was closer together due to cosmic expansion having been going on for a shorter duration. Our brains are capable of memory of past events by doing something similar but on a much smaller scale requiring less energy to move particles around given fewer particles to move creating a small scale simulation of the universe at an earlier time. We also do something a bit similar to time travel in video games with do overs which store information about where everything was at a certain save point which we can then return to.
Love it!
there is no backwards time travel, only current and onwards, as the highway is very populated
There are infinite worlds and each is connected to each other
Theres most likely in early time travel a time dilation, which means string theory is the best way to explain the paradox of meeting yourselves in the past.
Theres multiple universal dimensions that we all swap to every time a decision is made. Like the bit flipping aspect of dead or alive, it's the same with yes or no.
Theres layers of dimensions that have everything the same as us but maybe only .01 percent divergence. Now with current particle theory when they look at particle clipping out of existence, it's only our existence not all the dimensions. We are either forcing or particles naturally are pushed into separate dimensions or timelines.
This also acts on a wave function as well since as of right now we dont know where we are sending them or receiving them from, but with brute force approach ( 2 counterrevolution contained singularities with a particle)
Theres expected to a divergence between our original point and the end point depending on the length of travel. Meaning the divergence gets bigger the further you want to travel, so in theory you could go back and see germany wins ww2, or you could go back kill your grandfather (I dont know who wants to do this but anyways) and your father or mother wont exist, but it never effected your original timeline/dimension. Only way to get this paradox is if you go back on your linear original timeline, but in that case you might have something happen to you as you go to kill your grandfather so you never actually can kill him. Cops picks you after reports of bright light, you walk out wearing the wrong clothes for the period or you just look sketchy called a spy, get sent to the CIA or FBI and now you are arrested but you cant go a kill him.
I feel like time travel is possible but we cant go back to our original timeline, I expect there will be a divergence between your start point and end point.
1:11 did the coffee spill create the pyramid shape on your shirt?
More like a Illuminati sign
Time has speed limits from zero to approaching but never reaching the speed of light. See my essay that will challenge ...
Is time travel possible, yes or no Dude?
Its possible only if we solve the existence of multiverse or multiple timeline. And if warmholes do exicts with a proper dimension of existences
@Alcatraz Gaming - in other words, "No"
Its not only possible, it happens. But only forward. Theoretically there may be Neutrinos, or tachyons that travel backwards in time though.
Everyone mentions the time travel grandfather scenario but what about this scenario, you get in the time machine on July 4th, 2019 at 10:00 am. You go back in time to whatever date you care to. Then, you decide to return back to your time. You arrive on July 4th, 2019 at 9:45 am. Now, there are 2 of you. One of you, gets into the time machine at 10:00 am. He decides to go visiting the past and returns back to his own time on July 4th, 2019 at 9:35 am. Now what happens? Are there 3 of you in the same room?
First of all how to make a time machine
time travel is possible, but only going forward, not backward..u can accelerate time, but u cant go back..it is one way route..
This is so cool 😎
Few people throughout history have been able to prophesies the future. The key to unlocking a man-made version of it would be to explore the area of the mind that is uniquely responsible.

So in quantum mechanics we are creating another universe every second by choosing one of the another choices,and make multiverse infinite ??
A highly possibility
Hey professor I got a question. Without the armenian genocide (including the pontic greek and assyrian) and keep the less catastrophic ethnic massacres, like the one that killed 6000 assyrians in iraq. ¿does the word genocide cease to exist? even when raphael lemkin (the man who created the word) still interested in ethnic and non-ethnic atrocities.
What type of science is this. If I want to study this stuff what degrees would I need?
Quantum Physics
How do you know time travels in only one direction
Even if you traveled back in time in another universe your very presence there would change the timeline thus taking us back to the paradox.As intriguing as time travel may be I just don't think it's possible.
No one can answer how time travel works cause no one has actually done it. It is like saying what is outside the universe.
Time travel is impossible, thanks to the energy conditions for the stress-energy tensor.
I wish I understood what make superpositioning possible a bit more. Not just in time travel.
Wait so with quantum mechanics I killed myself and replaced myself like I never died in that universe and in the universe from where I came from I'm dead.So two theres universes were made where im dead and alive.But if I go in the time machine again and kill the me after I killed me?
What if a person developed a few small paradoxes which caused a change in the time & space?
How can we go to our actual past?
No need to involve parallel universes, universe remains "uni"-verse but it is not a conventional universe we perceive as such it is the quantum universe in its superposition, from this perspective the time from point of view of classical observer should be considered as not a one-dimensional but rather like branching bush/tree, all branches are real but not equally probable and in fact, each observer grows its own tree, its shape depends on the decisions/actions/thoughts observer made through his life; it's clear that "observer" in this context is not a classical observer but rather an assembly of the same observers in its different superposition states.
I wish it was the day this was uploaded I want to go back to 2013
Relationship between quantum physics and theory of relativity is very important.I am able for explain this relationship.sir.
Is that possible?
