- Some scientists take time travel seriously. Should you? What does time travel reveal about the nature of space and time? What about the laws of physics under extreme conditions? And don't forget those 'Grandfather Paradoxes', where a time traveler kills his own ancestor.

@christian babis By changing your perception about it. Example: you break a bone and expect some time before it can heal. However, someone else may break a same bone and heal themself instantaneously. The difference would be that deep down inside you you believe it should take time before you can heal anything in your body, while the other person does not hold the same idea and belief about _(linear)_ time within their ability to heal themself.
You've been creating the perception that you are traveling thru time _(that's what time is....perception which we experience)_ and thusly creating that reality for yourself where you experience aging, and such other things relative to your belief and perception about linear time, which also includes the idea and belief of cause & effect.
Tim is the only guy of your three who actually understands that there is a huge difference between math and physics. The physical universe constrains math. Not the other way around. It boggles the mind to hear a physicist say something like "The strength of gravity is controlled by the gravitational constant." The truth is that the magnitude of the gravitational constant is determined by the structure and content of the universe.
In just the same way as Scientology exploits ignorance, there are physicists who do the same.
This is why I like to study math because it is not burdened with emerging into the physical realm out of its own abstraction. Physics on the other hand needs to hold this emergence as its motivating force and ultimate responsibility.
Physics is a pretty shoddy discipline overall..
See you in the past, loser 🤙
@@alephnull7410 & Jack, you might really like a video in releasing on Halloween, "the actual, physical, reason why time slows at the speed of light". Bookmark me for later this week.
So you are the of arbiter of truth?
The First Law of Thermodynamics prevent time travel.
On the other hand, Time Dilation by speed or gravity is allowed by relativity.
Absolutely. But the first law is inverted in the enclosed region of a black hole. In fact negative temperature is abundant inside a black hole. This means that as you add heat to the system it gets colder and one particle of this negative temperature would boil all the galaxies in the universe.
Will your not a physicist so i don't see how your possibly know that time travel can be prevented
I have been travelling backward in time. Unfortunately I can't remember the future.
How
I just stumbles upon your channel and i love it!
Thank you so much for this channel. It is frickin’ fantastic. :)
Glad to see some new content.
I wish I could go back in time to wish that I could go forward in time to my initial wish.
DID IT!
It's August 8th my birthday ....I traveled back in time to watch this video , which was published July 9th
I honestly just had an epiphany while watching this. It doesn't really make any sense to say that time has a direction at all. To reverse time is a fallacy. What we are experiencing as time is a movement of objects and in our perspective, to reverse time would be the perfect reversal of the movement of objects in the exact coordination with which they arrived here from where they came.. so really, time isn't about time at all. It's about the movement of objects in relation to each other. We notice the year as a rotation of the earth around the sun. Several of those and you've got a century. We notice a minute as a rotation of a watch hand around the dial. If we turn the dial backwards does that reverse time? If we made the earth rotate opposite around the sun would time be reversed then? If we could make everyone age backwards would that be time reversal? If time seemed to be moving in reverse and everything was going backwards would that be time reversal? Or would we still experience it as time moving forward but everything is just happening differently.. I think time is really just our experience of objects and their movement and tracking them and following their patterns. To say time could be reversed is pretty much nonsense. Even if it was reversed, time is not happening in reverse. You always experience it as moving forward, it's just an alternate movement of objects. If time does start moving in reverse that throws out the idea of free will definitely as now time is on a track going backwards.. does this mean free will is impossible just the idea that if time started moving backwards it would be on a track? Or could we effect the past in reverse? Does it mean it's on a track moving forward?
I like the perspective you put this to!
The time never actually comes to a stop it forms closed loops. However these closed loops are extremely short.. they are within the planck length. They are the basis for extra dimensions in string theory.
I think of time as a plane. So, therefore it can travel in all directions, hence different "time lines", but it may also be fluid where theres one line that can be transformed into something else at any given point and since all we have are our memories, we would never realize it because our memories would also conform to the time line as it changes. Also,it may just be us that tries to understand time by saying theres a reverse or forward. OR maybe Im putting too much thought into it.
Time is the moving image of eternity said Plato.
I hope time travel isn't possible. I don't want my far future descendants looking back to see me wackin it all the time.

Public comments on this topic are funny. I like some of the “philosophers” of physics, like Prof. Mauldin, for being transparent & common-sensical as well as knowledgeable.
Another such colleague, Dean Rickles, provided maybe my favorite interview of all I’ve seen in this series when addressing the question, “Why is there Something rather than Nothing?”
APPARANTLY IF A DOZEN OR MORE PEOPLE FART DIRECTLY IN YOUR FACE ALL BACK TO BACK, ITS POSSIBLE THAT PERSON CAN GO BACK IN TIME, BUT ONLY TO GET REVENGE ON THE POOPIE HEADS THAT FARTED IN YOUR FACE. ITS THE LAW OF QUANTUM FACE FARTING.
I love listening to super smart people talk. #clueless I always feel smarter.
I am very happy to hear when he said'No, i disgree, time is time, space is space'.
i hate ppl say the word 'spacetime', as if they know what it is.
Time is the vibraration of the 3D web of the universe, it is the cause of the change of everything in the universe, with this change, we feel time. with this high frequency trembling of the web, the smallest scale becomes wierd, jiggling, jumping -- the quantum world.
Time is simply change relative to change. Time travel is pure BS.
Great video
The best answer I ever heard
First scientist I've heard say, what I always thought, that Time and Space is not absolutely linked. Time is Time, Space is Space. Keep it simple people.
Why should it be simple? Do you think the universe exists and operates with your level of understanding in mind?
@@b.m.c.2601 It certainly doesn't operate with your understanding in mind.

But in the center of a black hole, spacetime is warped so drastically that space and time swap and the center of a black hole becomes the future rather than a spot in space. If time and space were really that independent, there wouldn't be examples like that where they interact so fluidly. He never said they weren't linked. He said they're not exactly the same thing. He, in fact, nodded twice, agreeing with the concept of spacetime.
I love Tim!
Good insight in mu opinion.
When I went to bed last night it was yesterday. When I woke up this morning it was a new day so I’ve time travelled from yesterday
Sadly, he's probably right. Perhaps the best reason to believe time travel isn't possible other than the conspicuous deficiency of tourists from the future, is that if time travel was possible, probably there would be no Fermi Paradox because every planet in the universe would be colonized, or at least every one that didn't have an enormous impending catastrophe (you wouldn't colonize a planet around a star that's about to explode for instance), they'd have probably colonized the universe, not just the observable universe but the whole universe, by 100 million years after the big bang if you could go back as early as desired.
Robert and Tim , I do not know non locality well enough , I am still studying it , but is there some aspect of time travel happening in non - locality?
The only way I see time travel as being possible is by reversing the flow (vectors) of particles and their physical interactions so that everything in existence interacts backwards to a certain cosmic particles-orientation (with the time traveler being the only particles separate from this rewind). But this doesn't mean that we're actually time traveling - as we'd still be in the same universe with the current now, but in a different (old) arrangement of atoms. Such a feat seems impossible, though.
You'd have to know the exact position and momentum of every atom in the universe, and ACTUALLY have the technology to reverse them. On the other hand, if the universe is a simulation, all you'd need is access to the code. This would require you to get outside the simulation, though, because it would only be able to be done from the outside.
Exactly! Brad, you might really like a video in releasing on Halloween, "the actual, physical, reason why time slows at the speed of light". Bookmark me for later this week.
Maths is a tool to understand reality and quantify, but is not necessarily the nature itself. I could put some examples from my field, engineering. Sometimes, I have discovered empirical models which works really well in predicting an output variable, based on several inputs. I used PLS method (partial least square), which is a multivariate regression method. It essentially works by projecting input variables that have a high correlation into a vectorial space with less variables (=less dimensions), therefore reducing the dimensionality of the input. The point here is that it is doing the same projection with the output. Hence, I have worked with examples where input dimensions have been reduced from tens to 3 or four, but the single output variable has been transformed into a four dimension vector. It works really well with 99% of certainty, but it is clear that it is only a mathematical apparatus since it makes sense with the input, but the nature of the output is one dimension. In this example, maths are not describing the reality, but are very useful.
Anyone know where David Anderson went? Anderson institute. Worked on time control and time warp feilds.
I was late for a meeting AGAIN, argh. This is like the third time this month I failed to hear my hourglass stop.
I don't know what they said but i agree
Hearing that under the terms of quantum physics, apparently if time-travel were possible, it’d be something more akin to *Avengers* than *Looper*. Was interesting to me; I confess I thought time-travel and inter-dimensional travel weren’t the same thing. I always assumed that it would be possible to change the past. So basically, I watched and beloved too many movies.
I don't know if this guy is right, but I love that he defends the plain sense of things. Fussing over exotic theories can take us away from the awe that surrounds us at every moment.
Who else watching this on WA (Worl Archives) year 2364?
If some equations allow for impossible solutions, then there are only three possibilities:
1. The criterion on which we select plausible and unfeasible solutions is arbitrary, or
2. The equations are wrong, or
3. Both 1 and 2 simultaneously.
No, that's not true at all. For instance, it is well known that if there are 2 cosmic strings (1 dimensional gravitational singularities, an infinitely long string rather than a point as in a black hole - it's a different type of singularity than a black hole) that pass each other by at high speed and you flew figure 8s around them fast enough in the right direction, you'd go back in time. That is neither 1 nor 2 so not 3. The problem there is that cosmic strings likely don't exist.

Time travel to future is possible
It’s already been done
Iss astronauts who come down to earth are a miniscule fraction of a second ‘younger’ than the rest of earth
Now in the future with even faster propulsion etc they can come back to earth having aged 6 months while earthlings aged 60 yrs for example
Eli T wha- my 12 year old mine is blown and confused but also consumed on what your saying if that make sense
Never mind the consumer I mean interested
I feel if we could travel back in time, it would be like viewing a movie. Do we want to travel back in time to change it? Perhaps it depends on our intentions. Probability: there to change or to observe? It depends on that moment....
The very act of travelling back to a particular point in time would change the future. This notion of "being careful not to disturb future" is silly.
If time travel were possible we would have had visitors from the future. As some physicists are beginning to understand, there is no "thing" called time. It is a construct of the mind.
The fact is i can locate a point in space, that corresponds to an exact time , at that location, i cannot factor the past locations of space/time by a single particle? If i try to send a particle to travel back in time, there has to be an event location, of spacetime, for the returning particle to interact with, thus you cannot determine past present from future present? Betwixt any two points in space, there is but one time, betwixt any two points in time there is one space?
I wish I could go back in time back to her
It takes sunlight (the present travelling at speed of light) eight minutes to travel to earth; the present sunlight is eight minutes behind when it hits earth; the earth is eight minutes in the future and we are always living eight minutes in the future.
Are we living in the present, or the future? Maybe time feels like its moving forward because we are moving from the past to the future, and the present is an infinitesimally small slice of time on the way from past to future.
When something travel at speed of light no time is experienced and stays in the present; when the sun gives off sunlight it is the present and when light hits the earth feels like the present.
nice background
If you COULD travel back in time, it would start a different path for the future. You could never return to the exact same future you came from.
Travel in time also seems to necessitate travel in space. Even if it were possible, there's no point in travelling in time if you find yourself out of reach of anything you actually know. The point of this almost primal urge to travel in time is to experience events in the past or future that have meaning. To travel into the past only to be unable to participate in that time frame would be futile. Which is a shame considering the enormous effort and energy that would be involved.
Dark matter is wormholes. We can’t see them, but they are detected because of the materials traveling within the structures. This is due to the secondary detection responds of the time delays.
DONT GIVE UP ON TIME TRAVEL
Agreed
I WANT to go back to 31st October 2009!
About the possibility of time travel into the past my heart says yes and my brain says no. In the sense that I would love so fucking much for it to be possible but I also realize it most probably isn't.
Me too. I would like to travel back time
It's better to let people answer question...
Of course it is possible ! I do it all the time...
Yes
We travel through time at the speed of light (minus our motion through the unviverse) that'spretty cool.
If you calculate all the motion of all objects which your nestled within. Your moving way faster then light
I still don't understand what people mean by saying mechanics can run "in either direction in time". That's just nonsense. If a machine turns X's into Y's, and can be run backward to turn Y's into X's, what on Earth does that have to do with time??
Understanding time is simple. The SOL is the refreshment of reality at the Planck length. The Past is a record, the future is potential. All that is relevant is 'now'.
So basically, your comment is no longer relative? :P
@@CrazyBrick30 Now is always now. So it is always relevant. Relativity is subjective.
Soon I figure out how to do it.

The only way to reverse the direction of time is to entangle every particle in the universe and then set off the process of the big bang and make sure that all the features of the emerging universe remain constant. This is impossible as time itself does not begin at the big bang but evolves from the spacetime structure. It is an organic and dynamic force and hints at infinite parallel universes. Each one closed from the others.

Time travel is possible but we don’t have access to it at this time. Our theory of relativity and quantum mechanics is just too primitive..........
Understanding and quantum mechanics are oxymorons.

November 2008!!
It could be that earth is travelling backward in time, that if we travel at speed of light the backward travel in time is slowed to the present, while reality is travelling towards the future through quantum or somehow; giving the feeling that we are moving from past to future. In a sense time travel could be going on to past, present and future all the time as the regular natural course of things.
I wish I want to travel back in time back to my age of 6 years old.
Look, this business of "reversing the arrow of time" would accomplish nothing even if we could do it. The way I see it only one of two things could happen. Either a) everything continues to evolve, just as it evolves now, only in the direction of decreasing time coordinate. There would be no difference - it's the same evolution. That amounts to nothing but a "labeling change." Or, b) everything begins evolving backward. If that happens, how would we know? How do we know it's NOT happening on a regular basis? Our memories would unwind - we'd re-experience the same set of instants we previously experienced, except we wouldn't know it because the memories we had of it "later" in time would have devolved out. Time might reverse all the time - our progress through time may always be two steps forward one step back, but we still only have one continuous stream of actual experiences that create the memories we have at some point in time. In neither case do we get anything other than exactly what we're getting.
All this is is people who have watched too much science fiction having fantasies.
You can’t. There are too many realities and you would never get back home. You also can’t make the whole universe move backwards through time either.
I think in order in for time travel to be possible, reality would conditions we which we don't know of yet, from our current understandings and assumptions, no it's not possible
If space is expanding faster than the speed the speed of light, and the earth, sun and galaxy along with space, would this mean the universe is travelling backward in time?
Time is the truth about reality, but truth is entire universe as a whole and from all existing points of view at once, at given moment. We better stick to math, shut up and calculate, we will never understand time even if we could experience everything.
I don't like such certainty that time travel isn't possible any more than I would like such certainty that time travel is possible.
Experimentation is where its at.
We might never be able to prove time travel isn't possible, we might never be able to devise an experiment that shuts down once and for all every possible theorized method of time travel. But we can devise experiments for specific theorized methods of time travel that we may one day actually be able to build and run, one theorized method at a time. At which point we might be able to disprove a specific theorized method of time travel, but always leaving open the possibility that there may be methods that could work that haven't even been theorized or that are as of yet untested.
A better format for arguing the subject would be to discuss specific proposed methods individually. To just say time travel isn't possible is to not only dismiss current theorized methods, which there may well be reason to dismiss, but also time travelling methods that have yet to even have been theorized.
Some scientist who is trying to come up w/a method of time travel, even in his failure, might accidentally discover something else useful completely unrelated to that goal. Many failed experiments have led to great discoveries unrelated to the stated goals of said experiments after all.
Until it is known one way or the other, via experimentation that is, it can still be profitable to have less certainty on the subject. If we think we already know the answer, then we'll stop searching for the answer and that would be sad, even if it turned out after all the searching that time travel wasn't possible - the failed search for the possibility could still be fruitful.
Or to put it another way, lets not poo poo the people eager to prove time travel a possibility, even if we foresee failure in their future, for even if they are wrong, their failed attempts at proving so could lead to beneficial results for us all, or who knows, maybe they could even succeed.

You are *not* traveling *in* time... you are always in the present moment, and time is your measurement of how everything has changed relationships. You use countable cycling events to essentially document these changes. You never find yourself in anything but the present moment.

@@samuelmendoza9561 Einstein's Special Theory of Relativity tells us that the passage of Time is not a constant, it does not pass by at a constant rate. The passage of time is influenced by (1) the speed that you are traveling and (2) Gravity. If you are moving, the rate at which your time passes by is SLOWER than the rate at which time passes by for someone standing still. Obviously at the speed of an automobile the difference is very small, but it IS different. But if you travel at near the speed of light, your time passes by much more slowly than a person standing still. If you were in a rocket ship traveling to Alpha Centauri (a neighboring star of our sun) it would take you approximately 4 years to get there (as measured by your wristwatch) because Alpha Centauri is 4.243 light years away. If you turned around when you got there and flew back to earth at the same speed the total elapsed time for you would be about 8 years. But, when you got back to earth you'd find that THEIR time had elapsed by several hundred years. You not only traveled in space, you also traveled in time!
Time is also altered by gravity. The higher the gravity, the slower time passes by. Scientists have actually measured the difference in the passage of time for an Atomic clock located at the top of the Empire State Building compared to an Atomic Clock at ground level in the Empire State Building-because the clock at the top is farther away from the center of the earth and is thereby experiencing lower gravity than the clock at ground level.
The passage of time is not a constant, it is influenced by velocity and by gravity. Einstein proved that.
Time travel to the future is quite real and even to the past but u could never go back before the tech or phenomenon is invented on a practical lvl is a diff story
Technically you travel to the past when you travel at extremely fast velocities, it's just not your past, it's someone else's, I dont think the concept of traveling back to a point in time is that far fetched, just as space seems to be transverseable, time should also be since the two are intertwined
The time you read this I'm already in the future... Hehehe

@Donald Piniach that was in the past. What I'm writing now is in... The past😊
@Donald Piniach I have to confess... This is way over my head. But very fun mental gymnastics. Which I did before. Before the future. But I guess I'll have to go back to the past, stop at the present moment, which really is the past but for the one reading this, the past, present and the future. I guess only time will tell. If its not too slow?!? 🤔 😅But time is a great song from pink floyd. Made in the past 😊

If you look at the clock for time and also have travel experience, it doesn't mean you understand the physics of matter and frequencies. Anyone who's trying to explain this subject using word "time" are on the wrong path right from the beginning.
Not only is time travel in both directions possible, it is actually going on. Look it up. It is self centered to say that something is impossible merely because you do not know how to do it. Time travel requires transdimensional technology, which has been kept secret from the general public.
Back in the padded cell for you, I think.
In other words is Back to the Future possible?
He didn't consider quantum mechanics which proves the existence of multiple realities simultatiously existing at the same time and can onlye be collapsed by observation.
not exactly lol
Quantum mechanics proves no such thing. That's just one interpretation of the mathematical formalism. Maudlin is well aware of that possible model. In any case, time travel is no more possible with Many Worlds than without it.
Time has no direction. Change has direction and always forward. We confuse it as direction of time. Change is irreversible.
No past, no future. The Universe is changing at Present line giving us a false sense of past and future. Past is record. Future is next change state of present line with elapse of time. So time is elapsing, not moving forward or backward.
100% wrong
When you think about it, all records of the past could be false. And so maybe there is no true record.. no true past.. maybe the past is open to interpretation just like the future.. think how many times you argued with people over something that happened in the past. What is the truth?
I guess Mr Tim didn't hear about Dr. Ronald Mallet. He not only know time travel back in time is possible and he solved Einstein equation for that, but he even has a blue print for first time machine. At least practically we will be able to send information back in time to earliest point which will be when the device was first powered up. The machine involves circular lasers that in the middle will deform time and space by swirling due to circulating beam of light, likely very high power special lasers and also the circumference must be sufficiently small else the power needed grows exponentially. So first time travel to back will be sending information. His idea he discovered slowing Einstein equation is based on idea that if gravity can affect matter and light can affect gravity, then light can affect time. So it's funny I know this and the scientist not. I guess they are l are so deep digged in their own tranches they become to a degree blind to what others are doing. Time travel into future is nothing special. It's done every time you move relative to something, just you would have to move very close to speed of light to truly see it. Else the slowing of your time relative to others is negligible small. And traveling back it time out there is space you could try black holes entering under a special angle so you come out before you entered. Else practical we need to wait to Dr. Mallet to design a working model and we need to be content by simply just sending at best information back in time which also can also be send back only to the point machine will be make and powered on and no further. So a lot of limitations, but that is where we are at least which is far further then Mr. Tom claim we can't even travel back in time. Pls.
Take the spooky action at a distance particles.
They interact enless above the light speed so maybe also in the past.
But it is always random useless information and you can never send information to the past.
what do u get when u mix two motza balls togeather in a bowl? motza ball soup
Didn't Kurt Godel design a time machine? But the catch was you needed a god like technology and a ring the size of the solar system.
This is how I see it. The universe is not ruled by time. Rather, time is ruiled by the universe. Why? Simply because we created time. Therefore, it is no surprise that the universe has many different spots that will be able to dilate the time on your clock.
Everything that exists is a traveler in time. I once played a baseball game in the 1970s. Today I am typing on the internet in the year 2019. Therefore I am traveling through time. To say that I am traveling with time is a misnomer because that would suggest that if nothing existed there would still be time. But if absolute nothing exists, there would be nothing, including time.
Serendipity defies science. But, to someone who has experienced it, it is as real as gravity. It is also time independent in it's mechansim.

I have done time Travel in future , Really I have many experiences of Time Travel in future, it's not a hypothetical... If you interested in me then I will be share my experience and secret of time travel...
I don't understand the concept of Time Moving.
Time is a Static, everything else is moving, we are the ones moving forward in time. It's like if someone tells you space is moving around you so you can be somewhere else, no one say nonsense like that.
Time and Space is a mostly statistic part of the coordination system that is our universe, we can move to a time and place, time doesn't move to allow us to go to a place.
without time nothing could exist... there wouldn't be enough time. i visuallize us moving along a timeline.
So, it's not traversable in the normal sense of travel. There's no way to move in a direction of negative time. But we can go to a lesser positive time. There was never a time when time did not exist and, there is no place that space does not exist.
I can imagine reversing flow of time just fine, there are many computer games simulating just that. Why does it work in mathematical worlds and not in reality, this is a good question for me.
Only real difference i can notice is, mathematics can't do dreams, so imagination prevent us from time travel.

It's really hard to grasp the idea without trying to break down what the flow of time could be. Could it be that the flow of time is just an illusion?
We only register snapshots of a specific state and then in our minds we combine those and get a sense of a time flow. To alter the time flow we need to be able to jump between different states in some other way. The different states would be still present in different universes as in the many world theory. So by gaining access to the parallel universes we would in sense travel in time.
Hello Spot box.
First, a question: Does being able to _imagine_ a scenario (or in some imaginary sense, play it out in a computer game) indicate that the scenario necessarily represents any _real_ possibility? No! Indeed, it is perfectly possible to imagine complete nonsense. I am sure that I have spent too much of my own life doing just that.
Secondly, much works in Mathematics that doesn't apply to the real world - even in very simple cases. For example, '4-5 = (-1)' is an allowable piece of mathematics. More than that, it is a _necessary_ mathematical truth (it cannot possibly be false), but I cannot _actually_ take 5 apples out of a fruit bowl containing only 4 apples and end up having -1 apples left in the bowl. Perfectly sensible, even necessary, mathematics may be physical nonsense. Thus, that a solution to an equation allows a certain outcome not only fails (all by itself) to indicate that the solution can be a physical reality, it allows the outcome to amount to nothing more than a physical absurdity.
@@theophilus749 Hi Theo, let me try to defend mathematical theorem first, since i love logic of numbers.
Let's imagine there are only 4 apples in the entire universe, than talking about fifth apple doesn't make any sense, since after 4 there can be no material limits anyway and we can only ques mathematical abstraction. But if we know what apple is and new fruit is growing all the time, negative outcomes make perfect sense. Even if there would be only 4 apples left in the world, we could say fifth one started to grow right now, it's just not yet ready to became a part of our temporal equation.
Virtual worlds are not pure fiction, they are mathematical monsters where material form is replaced by some exact value. This goes same for Einstein and others idea about arrow of time, except computers can transform numbers back to illusion of reality. It's still an illusion, so anything goes, , but so is also entire human technology, made possible by exactly same mental process as computers do with complex number systems. All i say is, we can make virtual worlds work for real, if we could represent every mathematical value by some realistic quantum particle approximation. It doesn't need to be perfect, we can bend every natural law, if we are interested only in reproducing some special effect or experience already achieved inside machine electronics, those also obeying same real physical laws. Computers doesn't work the same way as artist's hand, human can draw anything, but machines can't and never will be able to because they can't simulate how it feels like to draw a dream. But what they can assemble from tinny mathematical dots, sure can be reproduced in real life, at least to some extension.
@@kjustkses why not, just play video in reverse :)
Please mind ball fall to the ground only because ground also fall, together with a ball and everything around, so you could also build room upside down and equip ball with some form of autonomous propulsion, set to correct appropriate trajectory angle. Idea is imagination prohibit us from making time flow in reverse, at least in some limited sense, not ordinary reality itself.
OK, so you hold events that invites time travelers to go back in time and attend, and no one shows up. So, what? Why would they? Why give away time travel to those not worthy to understand it? Huh?
Driving a car flying a plane is all time traveling
How can you go back or forward of your life by time travel because at
every moments of past and future of your life there is a version of you
already. So if you go back 10 years, you will only see what your 10
years younger version was doing. you can only watch but can not be
active because you are already there. Two same person can not exist at
the same time. So time travel is not possible.
😂😂😂😂 lol.. seems like you speak like Parrot, but have no wisdom...
Two same person present can exist at same time, only if somebody is not observing us. (Both person) at a same time!!
You need to learn quantum physics..😂😂😂😂😂
He is nothing but illuminati's d**********!!
In order to stay in the present, time would have to stop by travelling at the speed of light.
