- Matt describes the possibility of time travel through our knowledge of physics, what the limitations are (at least currently) and what technology might allow us to actually make time travel a reality. Physics professor This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
If I could time travel, I would go back to June 2019 so I can spend more time with my mom, she passed away less than a month ago and while I saw her a lot of times, we never spent quality time together, not unless we go shopping. I wish I can just go back and show her how much she means to me and thank her for being the best mom taking care of me. Edit:Thank you, all of you for the kind words, I really appreciate it.
Hey buddy, very sad to know

literally never seen a comment like this. Have seen plenty like yours tho...
@@mattunwin9770 its a very old joke .usually printed on the t shirt of "zany" and "off the wall " physics types. Its mildly humourous i suppose when you first hear it. I mean i get it , its new to you and you love it good for you. Reminds me of the time my friend came to me eyes watering all red and panting laughing hysterically. im like what!? He said if the vans a rockin dont come a knockin. He'd read it on a bumper sticker this is in 2019 he's 50 plus .how he never heard it i dont know
@@johnsmith-wx5fb You're boring.
I'm actually working on it myself.
Please believe in youself I need time travel. So many things I need to fix, so little time.
Help me do this
Lemme join so we can all do it together
What exactly are you working on?
Wait for the government they'll come to you for a little talk.
I’m here because I lost my son of 17 years old due to suicide on September 23, 2019. On my desperate moment in agony I cry and ask myself how can I go back in time and not leave house that morning and stay home with him.
Sorry about your son
I’m sorry for your loss
I’m so sorry.
Sending big hugs. It was not your fault or failing. I hope you can find some good bereavement counseling. I will pray for you.
@roxyrocks I lost my brother to suicide so I know very much the feeling of wishing I could go back in time. But in my journey towards spiritual enlightenment I have learned, that everything in life happens for a reason. That was just his predetermined exit point from my life in our soul contract. We will be together again and we are still together now, as our connection will never fade. I still feel him around me and in my thoughts, guiding me.
my personal theory is that if you want to travel to yesterday and meet yourself, then yesterday you should've met the you that came from the future, only if you travel in the same universe.(i'm no scientist but i love this kinda stuff)
You can't meet yourself in the same universe because you are yourself. Where would the extra molecules and matter come from in order for their to be 2 of you? You can't just split at some point. You'd be dead without half your matter of everything. Imagine if the time traveler just chilled with the last self up to the point of time traveling. Would the past self end up merging with the future self like mush and that being how the past self disappears from the present?
Some weird stuff this time travel crud. haha
You are correct if there is one universe.
@@Axxidous well..... Einstein said space and time do not exist... Only "spacetime" both are interwoven and are part of each other.... So in theory... The now me goes to yesterday where yesterday me already exist.... I exist in spacetime. Matter cant be created or destroy...... Going to yesterday and now there is two of me....but tomorrow when i left, there is none of me so thermodynamics is preserved. The same amount of matter exists in "spacetime" at all times if they are one entity as einstein said. And if i return to tomorrow then once again... Only one of me yesterday and one today (or tomorrow... Relativity.....) No more, no less at ALL times.
Quantum physics says every possible choice exists... And is just as real as the choice i made. If i go left... Then the reality where i went right exists and is just as real as the reality i know where i went left. It ALL exists ALL the TIME.
How can you meet yourself if you’re somewhere else?
This has no evidence just a thought, but what if each part of time(second, millisecond, etc) each has its own universe???
And “time” is just a bunch of symmetrical universes put together to create history???
If we could ask a dog what time it was... He may reply, "It's now, it is always now"
Profoundly funny. I'm tell'n you right now I'm gonna use that. Public domain, so don't come after me. But I'll be back in 2050 soon so if you find me there have at it.
Where have I heard that before? Sagan?
I like the joke but I just have to say, the word always literally means at all times, meaning there is more than one time
Um no he will just tell you the time lol
Thats funny because If you were to ask a moron the same question he'd answer the same.
If you understand what he is talking about, you are a legend.
Thanks.

I'd go back to 2002 and watch Ice Age and Lilo and Stitch.
Anyone watching while in quarantine to go back in time?
Yes. I'm already watching a lot of old films and TV shows wishing I were back in those times.
I wasn't alive in 2020 as I was born in 42069 but I wanted to learn what life was like then since info is obscure and Earth is long gone. I did use the CI*-819-X to arrive here and let's just say, I want to go back. Too bad Ragonizar won't be invented until like 75 years later, a key component to timetravel, so I can't go back. But yeah...
...also if you read this and thought I was being serious, I am sorry but this was obviously a joke
Time travel into the future is definitely possible. You're doing it now!
There is no present.
No, you're wrong! Time travel to the future is impossible!
There must be time travel they obviously went back in time to get the presenter that microphone from 1980. Somebody get that man a pop filter!
Was thinking the same thing. So annoying
You mean a spoffle?
And why exactly would he need a pop filter ? Smh..
Lol
Time travel, is a thought up process for something that is impossible. A fantasized aspiration. Let’s say for-the-sake-of-argument, you do.if you travel outside any part of your existence you will literally kill yourself, because nothing beyond your moment or cycle would be like an endless void of nothingness. Mainly because you are tethered to your existence here in this three-dimensional-physical-plain.
I like his argument. It's what I have been saying for a very long time. Ancient Greeks might have thought you cannot fly, yet here we are hopping from continent to continent. They certainly would not have perceived a rocket leaving earth and venturing into the vacuum. Those assertions were based on existing science at the time. Our assertions are limited by what we understand now.
Also what has to be noted is also the fact that experimental science wasn't a common thing back then due to obvious reasons such as lack of essential apparatus, unsupportive society, etc. So it was easier to predict things based on available logic.
Now I understand why Flash needed to run in a circle to jump through the wormhole to travel back in time. He was spinning around the cylinder. And it makes sense why Reverse Flash created the Tachyon Device. It all makes so much sense now. This became my favorite TedTalk yet. 😭🙏🏽
The answer is: "yes" - clicking on this video instantly transported me back 2 years in time.

it's POSSIBLE, you'll just be on your 'new parallel altered universe', or your 'new present universe' when you go back;
but you'll be gone forever on your 'real previous universe'.
Only if you believe in a non deterministic existence.
You might just discover that our one existence can be reeled forward and backwards like a cassette and that you going back in time always happened and therefore you never existed in an alternate timeline. Free will is a lie after all.
The problem most people have with understanding time is that they fail to recognize that time is actually three-dimensional just like space is and like space future time and present time and parallel time are all omnipresent. This basically means that everything that will happen in the future has already happened.
There is no leading edge to time in that the future contains no time, space or existence until it is somehow created with the passage of time. So, with this assumption, if one were to travel into the past then the past would already have record of it even before the future event leading to the time travel took place. Time is ever present, both past and future and is irreversibly interconnected with space.
To illustrate this I will use the following example:
If a person could exist in a place where there was three-dimensional time then that person could stand at a certain vantage point and see time in a panoramic view just like you and I might see our world from the top of some mountain top. They would see that time exists as a landscape, a landscape of what is in the past and what is in the future and what is all around (parallel realities and who knows what else?)
We can't see any of this because we live in a reality of three-dimensional space and one-dimensional time with the restriction that normal time can only move in one direction in space's three-dimensional framework.
This may or not make sense to some but this is how I see time if it could be viewed outside the restrictions of our reality.
The past, present and future are all happening simultaneously. Einstein, Feynman, Hawking all concluded this in a scientific manner. And then there are countless others in other sects (Taoism, Sufism, Indian yoga) that expand upon and share the same notion in more occult form.
Or, you can't change anything with time travel. For example, lets say some dude out there that claims to have time traveled is real. In his 'past' but our future he couldve looked himself up and seen the claim on yt or something (assuming yt still exists)but he didn't know that he had, or was going to go back in time and announce himself as a time traveler. Nothing can exactly be changed, but can at the same time. Kinda like we are doomed for whatever happens in the future. Let's say in the future Timmy dies. He is doomed to die at that specific time.He is however conscious and can make choices, or at least feels that way. I can explain more if needed.
Caleb Payne so basically our fate/future is already happening and planned for us.
If time travel evers exists in the future, then it will have always existed..
It did, the man and machine travelled to the past. The machine broke, he became broke, and now it's as if time travel never existed....unless you count traveling into the future...I just travelled into the future while writing this response.
@@LionsPE proof time travel
Stephen Collins thank you!!! Ever since I watched BTTF I’ve loved the discussion of time travel in the real world and the first thing that I told my family when discussing about time travel was just that, if time travel exist then it would have always existed.
You could not go back before the construction date of said time machine.... So today, It will not exsist...Maybe in the future......😎LOL
Bootstrap paradox . Information passed from future to the past
We need to focus more on time travel to the past and create a timeline where the problems on earth didn’t happen
Make it real! take me back!
Exactly!
And where Trump wins again instead of cheating potato head.
True!
Sure but unless it's me I will still be stuck in this particular timeline regardless of the changes any other time traveler might make to the past.
i donot know about others but i am an undergraduate physics student.I might not be a bright mind but surely i will devote my life for discovering the probability of time travel.

My favorite part is where he says “ extrapolate “.
time travel is one of my favorite subjects and dreams. I will always want to travel back to the 1980's, and thats the first place id go if we ever figured it out. Remember, flight was thought of as literally impossible by top scientists just hundreds of years ago. To just say time travel is not possible is a bit narrowminded.
How would top scientists think that when all they have to do is observe birds? No one ever created a paper airplane until after the Wright brothers? No credible scientist would say it is impossible, versus it is difficult, given the self-evident empirical data existing all around them.
Once upon a time many thought driving fast would prevent you from breathing. "Natural speed limits" (limits defined by nature) were defined by the fastest known animals. Therefore, no man could go faster and survive. Otherwise animals would have already done so.
Right on dude the 80s were awesome
Exactly the eighties were a blast! Better times and people were actually better to one another! Today is everyone for themselves and screw everyone else!
Yeah, and those people a couple of hundred years ago never saw manned flight in their lifetime. So I'm pretty sure that I will not see time travel in my lifetime...unless someone comes back from the future and shows me, which hasn't happened as of the writing of this reply.
I was waiting for a simple yes or no
Time Travel is possible and has been done.
It's called Time Dilation.
The faster an object moves the slower time moves for that object.
So if you traveled at light speed for 1 year. Multiple years would have passed at home.
It would be like traveling into the future
@@LordDirus007 problem is that you don't jump through time. Your perception is different. No one has dilated time to time travel. We don't have the energy.
Don't tell anyone I have travelled to past 🤫
@Juan Marcos Quiñones 😏😏😏 I wasn't telling u, I am telling to those who wants to know, and I didn't ask ur opinion
@Juan Marcos Quiñones nobody asked u personally do time travel exist and did it exist during WW2
me: has been told from multiple videos that I can't time travel to the 80's since I was born in the 90's, which makes sense.
me: continues to watch more time travel videos in hopes that one of them is going to tell me what I want to hear.
Kristina Asia meeeeeeeeee tooooooo!
Kristina Asia you’ll be surprised
Literally why I looked this video up 😂
Haven't you seen Quantum Leap?
why, of all things.. would you want to go back to the 80's?
Correction: Running faster than the speed of light does not freeze time. Everything just appears to be frozen, but in reality your just moving so fast that eveything around you appears to be frozen in time. However if you stayed in lightspeed time and just payed attention to someone walking. Well you would notice the movement they are making, however for you it would appear to be happening very slowly, but that's only because of how fast your moving.
If I could time travel I'd go back to 8th grade and do hs over again, but wanting to know what I know now.
Omgosh same
Same too in Highlands Intermediate School Pearl City Oahu.
Yeah....except you'll be the age you are now, possibly making that pretty awkward.
I think understanding the rules of chronology and placement and when and where you'd have to go to time travel is something even just any bright person could probably eventually come to realize by thinking long enough.
It's how to actually propel a physical essence through a non-physical power that essentially connects everything in all of reality that we can't figure out yet.
Great talk and well presented. Thanks! :)

It was a groovy time.
Peace, Love, and Donny Osmond.
Wait.......I guess Donny didn't come along 'til the late 70s.
I actually missed the 60s too, even though I was born in the late 50s. Too young to know what was going on 'til after it all happened.
You really needed to be born no later than 1952 in order to experience the 60s as a teenager, which would have been the ideal age.
I lived through it. JFK, Robert Kennedy Malcolm, Martin, riots in the cities, rich exempted from Vietnam war, cheap hope, cheap gas, so many got lost. College was cheap too. But I can't work anywhere and don't know why I'm alive. You would have enjoyed being a young miss in 1948, we still lived on TRUE lies.
My theory is if you travel back in time, you create an alternative reality/timeline than branches off from the point you traveled to and the original reality/timeline remains unchanged
Just like the avengers did
Jose Pimentel basically except their actions of removing the stones from the past probably should’ve had more effects when they returned to the further

@@ShangZilla likewise if our future self come to us today and say something like "do not eat chicken" but we do not get it why we should not eat chicken. But when we trust the advice and we not eating chicken anymore, turns out the future not getting any better since another problem pops out that this problem does not exist when the problem related to chicken existed.
Life will always have the problem to be solved or to be accepted.

Time travel CAN be done. If time goes forward, there is no reason it cannot go backward. And I know there are other timelines. Time is like a straight line. It has no beginning and it has no end (that we can comprehend), and it never intersects with itself.
Lucy Fur you’re correct.
This can actually tie in with singularity
Despite popular debate I find it natural that if traveling to the future is possible, then the past must be as well in some way

You should watch the Netflix show called Dark. It's based in Germany and totally goes along the third type of time travel you explain with information without an origin which creates a infinite loop. It is pretty spot on and gets more fully explained in season 2! (I just switch it to English dub)

Thank you TEDx Talks sir, thank you Mr.Matt Szydagis sir.
He even sounds like george mcfly! Liked.
Got to love when people always talk about going to the speed of light that we need infinite energy to push anything with mass there but never think if you can achieve light speed you would have real dampening systems shields and if you had that you would have anti gravity systems and mass would not meen anything so to achiev light speed or beyond would use less energies
Yup. Not to mention time doesn't actually exist outside of the relative perception of physical change. No timelines, nothing like that. The future is only changes that will take place. So altering our speed relative to other physical objects simply alters the relative rate of change. We can never go to the past because the past does not exist. The past is only previous states of change that would all need to be reversed.
If you travel back in time wouldn't you also have to move the entire universe? The earth, planets and the universe around them are in a constant state of motion and expansion. It would be quite the surprise to go through a time machine, only to find out the earth isn't where you thought it would be.
Yes. To 'travel in time' you would have to 'move' (wind and re-wind)the whole universe. (both back and forward). Alternatively, all 'times' would have to exist simultanously, (so that a 'traveller' could 'travel' to them) there would need to exist in all these 'times' part of the mechanism, a traveller 'receiver', so to speak. One would need to have 'travelled in time' to set up these 'receiver stations' One can easily see therefore that 'time travel' is a fantasy.
@@bigblukiwi Not fantasy so much as it is maybe a higher dimension we don't not have access to. At this time that is.
@@Neimfeltrite and as I often say, maybe there are fairies at the bottom of my garden, it's just that we haven't seen them yet.
If the future holds the ability to travel through time, it seems clear that no one would have the means to change past events. This would be apparent by the historical reality we all now share. And if someone was able to alter the past, nobody would know it had been changed except the traveler because all we would know is what we know. How a path had been diverged would be unknowable to us.
I believe transportation is more possible than time travel. Apparently when we look at distant planets we only see what they used to look like. With transporting ourselves to another part of the galaxy we could look back in time if we could focus on earth and alter the distance to view any time in earths history.
That is temporal observation. Its just an artifact of light propagation and relativity. Not particularly practical. And since AFAWKI you can't travel FTL, you'd still won't be able to observe the past of your current frame of reference (Earth) in any meaningful way.
"Oh look, there is the Solar System 2, 200, 2M yrs ago.".
And even if you could, its a lot more energy and time efficient to just open a history book or ask someone.
Seems like somehow, with a fast enough ship and a strong enough telescope, we should be able to at least look in on the Earth of the past.
Man, I just can't get through this. He's all over the place.
Because he's on a complete theoretical tangent that is completely irrelevant to actual time travel. Because time only exists as a product of relative change. There is no past, there is only the previous state of matter that has been altered, which we perceive as time. He's basically exploring sci-fi theory, not actual scientific knowledge.
If you could travel back to the past and see yourself as a 10 year old child. The moment you touch the hand of your former self, to shake hands, this would create an astonishing paradox. You would both erase one another by attaching to each other’s subatomic particles and just as matter and sub matter would annihilate each other, thus you in your present form and you in your past form would destroy each other’s sub-atomic structure.
I'd go back to the 80's when I was a kid; before mass shootings, before cell phones, before social media. I would give up everything if I knew I could go back.

I want to go back to the past to get my time back and do something else.

This guy looks like Rodney from Stargate, with a voice like Fry from Futurama
Agreed. He also sounds like a young Woody Allen, especially at 04.48 when he says "this is a question of engineering..."
😂😂🤣
He seems to have missed the nature of the 'paradox' in the twin paradox. He was describing simple time dilation. The paradox arises when one considers that each twin, relative to the other, is stationary, and sees the other as moving. Therefore it would seem that each thinks the other is aging slower than himself. Clearly they can't both being aging slower than the other. And THAT is the 'PARADOX.'
Except that it has been shown to be faulty and no actual paradox is involved. One of the twins moves through different inertial reference frames, which means that symmetry of relativity is not invoked.
Yes. You are right and he has the paradox wrong.
Paul Smith while shaking my head, I was heard to say,”Otigit Otigit.”
Man time travel has been existing for a long time, this guy must have just saw the movie I saw about the guy that went back to the Future a bunch of times I forget the name of the movie but I saw it actually happen and you can even watch it yourself because someone taped the whole thing.
I hate myself for making bad decisions without being aware of change!!!!!!!
This guy is brilliant
If time travel is possible, it will only be forward or backward on the timeline inhibiting any changes.
If not, any travel will end up in the wrong place; we are moving with incredible speed through the universe.
Even subatomic particles will cause paradoxes otherwise: what happened if I today detect a subatomic particle in my detector and tomorrow decide not to send this particle to the past?
Time travel to the past would mean:
- objects that have decomposed or dematerialized are somewhere still intact, like the hamburger you ate yers ago.
- events that have taken place are still taking place in some dimension, and they will have to repeat constantly.
- our conicious experience of events should also be be repeated contsantly. When I meet myself from 20 years ago, the same person with the same consiousnes is confronted. This means two sets of thought proceces from the same person are going on at the same time. Wil my person be duplicated?
It's horrible cause it makes the the universe fixed. BUT no matter whether I like it or not; you are likely right. Reason: because entropy - the disintegration of things would have to freeze 🥶. It would have to stop. There would have to be a freeze frame of events. Then and only then could the events change that have happened in the past. We've seen it in movies. A freeze frame - the characters are altered - the story resumes.
I believe, the Physics or Science (that we know of) alone won’t be enough to understand or explain such phenomenons because we base our Science on the things we perceive.
Consciousness can travel into the past and witness happenings at any time and place in history. The consciousness can also go into the future.
Just so I'm clear on something.... A flux capacitor will or will not work?
Greg Skinner Im no historian BUT I saw/read somewhere that a guy named “Doc” made one work in the ‘80s . So I’m leaning towards yes.
Im going to try hanging a clock over my toilet using a wobbly stool... I’ll figure this out after I hit my head and wake up..
The FC works!!!
Yes but you have to power it with 1.21 gigawatts of electricity. You can do this with either a nuclear reactor or a lightning bolt.
Only if attatched to a delorian.
The two timelines existing sound a lot like the show Dark on Netflix. Amazing.
What about in real life!?
Netflix sucks!!!!!!!
I use to watch this when i was kid and wow he was on point back then .
This video is just a bunch of atoms talking to an even larger bunch of atoms.
*D E E P*
It's creepy and spooky, we're all from the atoms family.
and we thought of that with our brain which actually named itself
This video is a bunch of transistors that are either on or off representing bits of information representing frames and sounds in a certain order that are the result of a bunch of atoms reflecting certain wavelengths of EM radiation reaching different parts of the lens in what we know as video camera. While simultaneously vibrations traveling through a medium of mostly nitrogen and oxygen at varying frequencies and volumes entered an audio recording device to be stored digitally the same way the images are stored. You're technically correct
Stahp!
Negativity energy, and dark matter is hands down the most mysterious thing in the universe.
DANNY PHANTOM ?
I would have to add quantum entanglement to that..
All of which are just place holders for our ignorance and the problems/inaccuracies with our current physics models.
@lil chromosome _ punctuation is a real thing buddy.
So both of those are clearly explained in their respected areas of science what is it you find mysterious
I want to go back to the past, I can't take anymore of the Era i'm in not even for one second
The biggest problem to time travel is identifying a location in space-time. People often think of a machine being at the same location but it’s not. The earth is moving around the sun, the solar system around the galaxy, and the galaxies are expanding apart. A single place in space is near impossible to maintain and thus virtually rules out time travel as it pertains to gravity and special relativity.
On the other hand entangled particles (QM) seems to provide some potential because experiments have demonstrated that they are connected at a speed that is instantaneous (faster than they can measure at 10k times the speed of light.) To me this suggests a connection outside of space-time (possibly a dimension) where the past and future can be connected. The question then becomes, can enough particles be entangled in a fashion that allows a person to step into (and immediately out of) that dimension. I suspect that the interval traveled would be based on the vibration frequency of the entangled particles.
Honestly, the concept of teleportation. Seems more realistic than time travel. Of course travel to places where time is moving faster or slower would seem to be the best opportunity to go into the past or future. Outside the galaxy seems like it would be much slower and towards the center of the galaxy would be much faster. So, travel to that place instantly, wait a certain amount of time and then travel instantly back to earth. This combines relativity / gravity and QM to achieve.
Plus, if you believe the soul is real, would such a journey disconnect a person and soul for a wide variety of reasons. Who would want to go first?
Well said Mr Stark.
I make it a habit to travel back in time one hour every year in the fall and then ahead one hour in the following spring.
I traveled back in time on LSD
Cool keep wrecking your brain so that I will have less competition for your job!
MR FREEZE-98 Steve Jobs started apple computers with a little help from LSD, you unevolved fucks.
Zeke Banister lmao you are so clueless
John probable the best way to time travel,,I did it with mushrooms ,,cheers mate ,acid fucki g rocks too
What did you see in the past?
neal degrass tyson had the same idea of using light to go back in time when his dad died of a heart condition. much love to those whom lost a love one. you may not be able to travel in time now but can make an impact to save others now. R.I.P to those lost.
I ain’t got time for this but I’ll watch the rerun Yesterday
Instead of building a time machine ourselves, we could just build a landing spot for a time machine and wait for visitors from the future.. easy
It's called Burning Man.
You will get a nobel prize
The past exists solely in our memory and the future exists solely in our imagination. Given they both exist in the mind, how do we travel to a place that exists solely in the mind?
I love this guy. Genius is on the spectrum.
Carlo Rovelli describes time as a heat phase transition. Heat changes matter. It changes you and your surroundings, and what you experience is energy transitioning and transforming matter. There is, based on this, one direction for existence; forward. To me that's why this is untrue.
I wish i could go to the late 80s or 90s. I wasn't even born but I'm damn sure it wud be better than now
My dear, I lived through the 80s and 90s and I can assure you that it was a lot better than it is today. But it is going to get better from here on out and then hopefully we will feel that 2020 was worth going through all the rotten things that we had to experience.
I lived through the entirety of those decades. Can confirm, they were the best of times. The peak of human civilization. 1993 was the absolute paragon. Everything, everything amazing happened that year, or within 1 year of it. The best music, the best movies like Groundhog Day and The Mask (which is why I say within 1 year, that was 94), the best video games (Doom, mortal kombat). If I had a time machine, I'd live in 1993 indefinitely.
Plus I'd have my most special kitty back.
@@medexamtoolsdotcom it's depressing that we can't turn back time....
Time is not about mass, so much as data sets and the arrangement of particles. It should be easy to travel through the timeline of a universe that you did not originate from, and in a multiverse that could be a matter of altering atomic vibration to shift to that other universe. If we live in a holographic universe or simulation it gets even easier, since it would only be a matter of altering the constructs of the observer much in the way remote viewers do.
If you change something in like past like if you move a pencil 1cm along, that could make the person sitting down take longer to pick up the pencil then getting less work done and his teacher noticeinge he got a question not done and then he takes different steps which could make him think about of something else
2nd law of thermodynamics ... it is impossible to go from your present to the past, but possible to go into your future if you ran faster than the system that you belong to!
You can travel to the future by slowing time via time dilation but you can never travel to the past because time always moves forward.
@Conexus X18 Yes there's just but TIME. BUT you can go to the future through time dilation as I said. Either through speed or gravity, it's a hack.
