So this means I can blame all my mistakes on the lag? YES
Omg lol
😂
Oh my God your right
Flash actually discusses how the world is so slow and boring at times because of this
Yeah. The song "Ballad of Barry Allen" is essentially BA Flash singing about how boring and lonely it sometimes get experiencing everything so fast.
+Azmodeus87 Cant he change his perception of time though?
TheAsianPlaysGames I imagine he can to the same extent you and i can, holding back. Just think how boring it would be to play a game you really like, but where everything lagged at 5000 ping.
TheAsianPlaysGames look
Lol, you don't need superpowers to realize the world is slow and boring.
Flies can see life in bullet time and yet they still fly into my face.
+AbaddonAlmighty its not like they are smart
Oliver sobhi Zakhary You're not wrong.
Can I do a very bad joke?
+CountOrlokNosferatu Shoot.
Okay.
Flies hit you tough their bullet time thing because... you have a shitty face!!
Just kidding. No intention to offend you ;-)
So... if Flash experiences the world by processing information at or near the speed of light, that means that when he goes to sleep at night, he dreams for what would feel like billions of years. One of Flash's dreams lasts longer than all of human history.
oh shit
This doesn't NEED to be true. His unconscious brain could assume 60fps, like a human, or his brain could actually do that. For the Flash, one dream could potentially seem like it lasted longer than all of humanity, but when he wakes up, it's just the 8 hours he was asleep. Remember, he's just fitting more time into the "existing time" that humans perceive.
Beemer It doesn't have to be true, but it's haunting to think about. I'm definitely aware of how time would work for the Flash 'if' he processes information dramatically quicker. Because it doesn't make him smarter, his experience of time would just be that it slows down, possibly to a screeching halt. The real world would become a horrifically boring place and he'd likely be catatonic because... you can't really interact with the world if it takes you 100 years to move your arm (I'm using the Flash as the reference frame when giving numerical examples of how he would experience time). But in his dreams, time would appear to move at a normal pace (at least, he would have 'normal' dreams, however time works in dreams), but they would last an eternity for him. If he can control his perception of time, can he control his perception of time in a dream state? Logically I'd assume not if his experience of time is a conscious choice for him. Either way, the idea of being trapped in a dream for an eternity... every time you go to sleep, is disturbing.
Not so much trapped as I don't believe his body naturally controls time as much as it's him physically doing it. I get what you mean, though. Like if he had a nightmare and the reaction to that nightmare was to slow down time, then his brain could stick in that permanent slowed time. That would be scary, but he'd get over it. It's also not eternity, it's just a very long time, like virtually eternity, just to wake up and be in his normal, everyday life.
Beemer Well yeah, probs shouldn't of said 'eternity' for dramatic effect lol. And I'm definitely not arguing that the fictional Flash would experience reality or dreams in any specific way as I just honestly don't know enough about him. I was mostly using him as food for a crazy thought experiment. If he did in fact experience the world as I've laid out, there wouldn't really be much of a fictional character left (at least not one that could maintain sanity).
wow Kyle, I'm glad you got more comfortable and dialed up the energy.
Kind of ironic that he started with talking about the Flash and talking way slower than usual.
Looks like Chris Hemsworth, sounds like Jake from Vsauce.
He must be vertasium then.
I cant unhear (not even a word) jakes voice in this guy now
There's a beetle that runs so fast, it can't see anything while it runs. This is because its brain can't process its surroundings fast enough and it just sees a blur, so it has to stop every few feet to look around to know where its going.
tiger beetle
Didn't think I would find you here
You should do a video on how he would dream. Because he thinks so fast and because we normal humans can experience months within hours into a dream, would he then experience years within seconds? Does that mean each time he sleeps he can experience a whole life cycle?
This is actually a really interesting concept, thanks dude!
no flash thinks fast because he want in his sleep he dont have control of his body so its not fast average speed
+Cool Gamer So why has he got fast metabolism? He can't slow or Speed that up. dreams are part of your unconscious thus meaning it reacts as if involuntary.
+Cool Gamer And when you say in his sleep he has no control over his body are you assuming that somehow he heals slower and metabolises slower in his sleep?
I always wondered, If the flash were to run say... 3000 miles in less than a second, surely because he perceives time so fast it would feel to him like he has taken the time it would take any of us to run 3000 miles and not actually be superspeed as it would take weeks in his POV?
I think he can control his perceptions.
Maybe one of his powers from the speedforce is super-patience
scientifically he should see things really really slower (or not even moving at all) but say he runs 15% the speed of light that's fast enough lol
+Roman I don't know how any speedster can wake up in the morning, to an alarm clock that beeps so slowly or staring at a ceiling fan that barely moves at all.
Remember that they only feel time slowing when they are running near the light speed, if they're just sleeping or sitting on a chair they're like a normal human.
anybody else get mind blown by this guy every once in a while? the one where we're never actually touching anything because there's always electrons or something in between us got me too, cant remember the exact one,been a while, but it was freaky to think of for a second
the flash can precieve events that happen in less than an attosecound and the flash does not see everything as extremely slow this only happens when he needs tp
OMG...I JUST watched Episode 150 and came to watch Ep 1......HOLY Kyle Looks different. 3 years makes a HUGE difference
It must be hard to write backwards like that.
+Anthony Cordero what if they just flip the video?
***** nope
yes instead: watch his Ultron video and pay attention to the iPhone shown at 0:55, the Apple logo is mirrored
In the quicksilver video the buttons on his shirt switch sides when he's righting
they flip the words
This show, I like it. Another!
I actually understand that reference.
So the final conclusion is... Flash is the PC master race with THE best framerate?
No bro. The flash can move faster than time. And I don't mean time travel.
+Jose Garnieryou mean trans-time velocity right? moving faster than teleportation
wow, glad someone knew that.
That's so fast that it sounds fiction in fiction.
+Catumbo he once fought a teleporter, and couldn't catch up
+Lego Smith and once he fougth the cosmic gamblers and won
its all about the stakes
love these new shows with malik, dan and now kyle!
0:34 did you just draw the PBS logo?! Awesome! 🤓
next week: the mathematical equation of why Batman is awesome
Don't tempt me!
- Why is Batman so awesome?
- Because fuck you. That's why.
Batman is a scientist
It's quite simple, Warner Bros. + Lots of money = Over Promotion of Batman
damn, that is some strong scientific evidence you got there
God I love this old because science music that plays at the start and the end
I'm blinded by the science!
One of my favorite Flash stories is Stop Motion. It is a novel, not a comic, but it gives a completely different interpretation of Flash's power that I really like. In the novel, it is explained to Wally West(Barry Allen was still dead following the events of Crisis on Infinite Earths) by a trans-dimensional being with a much greater control over the "Quantum Power" or that particular dimensions name for the "Speed Force," that super speed is really just a side-effect of the real power, controlling quantum energy, which is the very fabric from which all dimensions are formed. Some one in full control of the quantum energy would able to travel much faster than the speed of light, by taking a short cut through another or many other dimensions(not the same as teleporting), and they would be able to form energy constructs of quantum power in a similar fashion to a Lantern ring, or even warp and bend reality itself through direct manipulation of quantum particles.
whoa... no wonder damn flies dodge rolled up magazines like Neo in The Matrix
Should do an episode where you prove the flash (or any fast person) must have super strength
Either to push their bodies that fast or to be able to hold any object with the amount of drag it must have against it
Please keep on doing this ! It was amazing only I guess the delivery needs to be faster but if it stays this good this might be the weekly thing I wait for
He explained how the Flash's brain worked in 3 minutes. That's pretty speedy, imo.
Really? I liked it, but I found myself hoping it had gone into a lot more detail. I'd like to see the 10 minute version of this.
Jaibeer Dugal TheSwamper Now, 5 years later, he both speaks faster AND makes videos over 10 minutes!
I had this existential crisis a few years ago when I came to the realization that time was completely relative to the speed at which one processes information.
*2019*
Who else is here to see young, hairless Kyle? Adorable :D
aww, look at him, so polite, professional and clean cut...and no SURPRISE LIGHTSABER!!
Prepare for everyone trying to be smarter and prove you wrong Kyle. Lol.
Great show though. I'm glad Nerdist listens to people and what they want to see!
so i should except the concept that if i see nothing(covered my eyes in total darkness) im gone from reality entirly? well i guess children arright when they hide and seek then:D
Kegan Terry The DC comics confirmed that the flash is x20 faster than light.
This video marks the beginning of an epic series. Also...
**SURPRISE LIGHTSABER!!**
Great show Kyle
I especially approve of the use of The Flash
I'm here from 2019 where we have self driving cars and Kyle looks like Thor's younger, more nerdy brother. What a time to be alive!
Was that humming bird thing a reference to "Ballad of Berry Allen" by Jim's Big Ego? I hope it was, and am gonna assume so unless you tell me otherwise because of how much I love that song.
amazing song!
+SupernerdScrawl i wish there were more superhero songs as good as "ballad of barry allen"
I must say, you happen to posses one of the, if not the most symmetrical face!!
And it's so cool watch the beginnings of something so awesome like because science!!!
when superman or any other superhero catches someone falling from a high building do the possess some sort of power like the speed force?
It would be more mercy to hit the floor then him catching them in most cases.
+Zero Rei lol
+Zero Rei aye, agreed. Superman or flash moving at those speed can literally kill a person if he/she is in their path.
There could even be mini tornadoes generated in their wake and a supersonic boom due to highly compressed air in front of them.
Vincent Jack well in the flash's case the speed force prevents it, and this reason is exactly why superman has to extremely regulate his speed on earth.
+Vincent Jack the flash can think at speeds of an atosecond so he can dodge them
Not to mention if you catch somebody falling when going fast enough you transfer it to horizontal velocity instead of verticle.
There are also some animals etc that perceive the world in a much lower framerate. I believe some of the long lived tortoises etc perceive it at like 10frames.
Its amazing when you realise that so many creatures perceive the world so differently than we do.
Making eyesight and fps, just doesnt work. There are many factors, when you move in the world + when the world moves. Example in a video, if both the player (viewvpoint) and the world is moving, I can instantly tell difference between 60 fps and 120 fps. Itøs not as simple as saying "we see at 60 fps"...
We see at 60 FPS in the sense that if life is an infinite stream of frames, we pull 60 of those frames every second and weave our life experiences from that. The more frames you can pull, the closer you get to that infinite "now." Trippy.
Kyle Hill We can pull more than "60 frames a second" (even though its hard to compare fps of a film or game to real life). I have a 120hz monitor and the difference between 120 and 60 in games is huge I bet the majority of people could easily distinguish the difference.
*****
Sure! What I am referring to here is the "Critical Flash Frequency," or the threshold at which a flashing light becomes a blur (when we can't distinguish individual flashes). So a housefly could see 250 blinks of a light per second. I'm arguing that The Flash's C.F.F. is then nearly infinite, allowing him to pick out any frame of life without missing anything.
I like the video quite a bit.
Just one problem: He can sprint at MULTIPLE times the speed of light.
He can react in pico seconds.
He does things like get shot with a high power sniper rifle - WHILE ASLEEP - and get waken up by the pressure of the bullet contacting his skin, and then proceed to move out of the way before the bullet can cause him harm.
He has also saved a city from a nuclear blast, by moving ALL THE PEOPLE to a safe distance away by himself.
Calculate that feat, move the people of a city by ones and twos - he carried them - a safe enough distance away from a nuclear blast.
His speed is INSANE.
He can move at infinite speed making him stronger than superman in fights because the speed would create infinite mass. he has infinite speed and has raced black flash to the end of time, all of which is physically impossible because he would only be able to go at 99.99999 recurring the speed of light.
LoL Stacker: That's according to OUR physics laws. You are forgetting that the Speed Force, that gives Flash his powers, is an extradimensional energy that can bend physics. It's one of the staples of the character.
Also, the concept that an object at the speed of light would create infinite mass is a misconception. Actually, an object going at the speed of light would have infinite KINETIC ENERGY. It's more easily explained in terms of mass, but that's not exactly correct. In fact, an object going at the speed of light would have ZERO mass, or, better said, an object with zero mass (in its neutral state) can ONLY move at the speed of light. Photons have zero mass and move at that speed, obviously.
Shendue wow thanks, he was thinking to realistically :D
T
and that is why the flash is my fav superhero
Well got to say of the four shows Nerdist makes, I enjoy this one the most. With news being a close second.
The Flash moves at around 23,759,449,000,000,000,000,000,000,000,000,000,000,000,000xC
August NKK - use scientific notation please
KDGaming trans-time velocity smh.
Александр Сальников - n i c e
I can't recall the name of the issue, but in one flash comic; The Flash went from the edge of the universe, to earth in less than a plank instant. If memory serves that's trans time velocity or something. Which is faster than instantaneous travel. The comic says he did this by tapping into more of the speed force than he has ever done before, and he tapped into the kinetic energy of everything on earth.
Pretty hard work that was...
Lmao. Hi flash. Which one are you? Barry?
Barry allen
Well you're very good at keeping your secret identity aren't you??? I better drive over to Star labs and plant a bomb. Maybe I'll pay iris a visit too.
why flash is faster than you think..answer is......the storywriters and film wanted that
why do you hate fun
I really enjoyed this! Can't wait to see more from you!
NerdistSauce!
Coming back to the first episode, Kyle is much more subdued than he is now. Crazy haha
Didn't even watch the video yet and I can already tell ya that the Flash(Barry Allen) might quite literally be the fastest fictional character of all time. He doesn't merely just possess the power of the speed force. He IS the speed force.
zoom is faster tho...
+Cucas 360
No, he is not. In the show he is...for now. It looks like they're about to bring one of The Flash's other obscure super powers. The ability to steal speed from other speedsters. In the comics it's ONLY Barry Allen who could do this, and he learns to do this when he becomes one with the speed force. The speed force is the conduit that fuels Barry and other speedster's speed.
+Disgusted Batman Uhm, no?
Barry isn't the fastest Flash, Wally is, despite Barry being the speed force itself, his connection to it isn't as strong as Wally's because Wally can't be disconnected from the Speed Force.
And Barry isn't the one who stole speeds, it's only Wally West that has ever done this.
Disgusted Batman wow fuck you and the spoilers ;_; but thanks thats cool to know xD
+Cucas 360 eh not really a spoiler, the show can and has gone in different directions in the past ie particle accelerator causes almost all the metas to get their powers when it wasnt that in the comics.
"I can think at the speed of light, I can perceive events that last for less than an attosecond, I can run faster than time."
we see more than 60fps
+Onix but we can adjust/react up to 60 times a second. As human reaction speed has some delay. It's not about seeing, it's about readjusting your movements. Rebalancing a broom on your fingertip etc.
+SirJMO This is why if you were vaporized in an instant, you would feel no pain, because the tactile receptors would have no time to send a message to your brain saying "GET THE &%$# OUT OF THERE!!! D:"
Cody Hines if indeed instant, yes we would feel no pain, but we could feel pain before we have time to react, which would be the time between when the nerves signals reach the brain and before the brains signals reach muscles.
+SirJMO Actually it only takes 1/5th of a second to react to what we see
TrizoParzo14 100 And I say it's even less time.
For example the muscles in the legs vary their tension to keep a person upright, this is very complex and has been trained from a young age to be automatic, we don't even think about it anymore as adults, but this happens many times per second.
However I do agree with the 1/5th of a second statement if it's to make a decision that requires the brain to be involved.
Actually we don't see in 60 FPS or any FPS for that manner. We see the world in a continuous stream of photons which is why we can see the difference between a 60hz display and a 75hz or 144hz and above. We do have a limit of how much light we can process per second but its not tied to our technology.
Where did he get this fact that our eyes see at 60 FPS?.
Idk where he got that. Humans can see at far higher rates than that.
WelkinAtDusk I read something online about eye pixels and it's supposed to be like 124 or something... it's been a while, but I would just do some research about the eye. It's all pretty easy reading.
its not about how high we can see, its about how high we can see AND distinguish each frame from another
I just traveled back in time to see this, and he starts talking about how we are living in the past.
...only 3 minutes? That is really short compared to what is is in my time period.
there is one huge glaring mistake in this. And it's not that complicated. Lag≠ refresh rate. We don't se the world in single frames that are on and off, different parts of the image will refresh when other don't.
There was a baseball player, that claimed to be able to see the frame borders while watching films in theaters.
Someone has never used a 144hz monitor. The "60 fps" thing is bullshit.
you do not perceive life in "fps" in that point you're right.
Have you seen actual video with 144 fps? maybe 120?
I'd like to see the person who can point at a screen and say "yup THAT is 144 FPs"
(if you are one of those who uses a Television wich claims having 400Hz good luck finding something providing that amount of fps)
i have heard this kinda thing alot lately... just a question: What benefit do you have of a 144Hz Monitor against one with 120?
On the other hand what do you want to sacrifice in order to achieve these kinds of fps?
you cant tell me you like to watch youtube or movies on your computer at these refreshrates...
so games?
what kind of system are you running to get up to those numbers? or do you play with less than full HD?
graphics set to low?
Instead of getting monitors with (too) high Hz maybe get 3 (peripheral vision extension before you ask for what you would need 3 monitors). or get one 4k and enjoy that.
Dont get me wrong: i do not know what you're playing. If you feel more comfortable with lower graphics but higher fps thats yours but as i only have your comment to go on id like to point out that it sounds like you want to say 144Hz is a must to enjoy moving pictures, wich is wrong.
Lonlyguarder I am able to point at a monitor and go "Yep, that's 144hz" with 100% accuracy. The difference is real, you just haven't seen it.
thats what i was expecting... "yes i see 144Hz!" but the rest gets neglegted.
ill ask again (as you are able to see it): what benefit and what sacrifice?
Lonlyguarder Benefit: It looks better
Sacrifice: Performance
your smugness: off the charts
I have a 1440p monitor running at 144Hz.
Obviously watching UA-cam and movies it makes no difference since most content is recorded at much lower FPS. The benefits are really only felt in games. It is a pretty perceptible difference playing games at 144Hz as apposed to 60Hz. I actually get motion sickness playing games (First Person view) below 60Hz because of the perceived 'jitteriness'.
For me, the higher refresh rate lends to a more immersive experience. I have a GTX 980 Ti, so I can play most games at the highest graphics settings while still maintaining 100+ FPS.
It is a pricey setup, but the entertainment value I have gotten from it has been well worth the expense.
If I were to make one reference to the plays I'm in, it would be "And that's how the adventure began".
60 fps ???!! really -_-
Yeah and alcohol causes lag.
^_^"
Yep this why every steam community thread complaining about a game not running over that frame rate is regarded. They can't physically see the extra frames anyway
well, roughly
***** I've literally been testing this since I saw this video. Showing my friends two games side by side (one on my brand new 1080gtx pc and one on my wifes 760) set hers to vsync at 60 fps and left mine unlimited, same game running on same settings with same brand and model monitor. Numerous hardcore gamer friends we have could not tell us which one was locked at 60fps.. . . so myth busted? Of course. Its called an optical illusion, we WANT unlimited frame rates on our PCs to look amazing so we mind fuck ourselves into believing they do, because we pay alot of money to get them and we need to justify it.
Honestly what DOES matter is resolution and pixel density if you want your game to look better, not just extra frames you'll miss if you blink at the lower resolution.
TLDR: FPS is overrated, resolution makes games look better
DeathWhitch
Thaaank you! Exactly!
Whats most interesting about the lag between the light traveling into our eyes, and when our brain processes it into images, is that there is no audio lag.
Like when a lightning bolt strikes, and you hear the thunder seconds later. Technically, this should happen when we speak to each other or watch tv, the persons lips should be moving out of sync with what we hear. But the brain is somehow able to synchronize all this into a perfect stream, despite delays and speed differences.
Scientists still don't know how we are able to do this, but we are.
Because science.
+DreamJuice420 its funny you say that, because for me, its actually out of sync, i hear the person before i can see them talk. granted its like a split secound, but its still there. And got is it annoying.
Ah thats gotta suck. I had heard of that disorder.. but hey, I suppose you're experiencing reality more accurately than the rest of us
+DreamJuice420 The lag between lightning and thunder is because light travels faster than sound. The light of the lightning reaches your eyes before the sound of the thunder reaches your ears.
This is also why the lag is longer when the lightning strike is further away.
+ShadowKick Lightning actually doesn't move at the speed of light. It moves about 1/3 the speed of light. But, he was using that as an example of how it should be when we talk. You're both technically right tho
The light from lightning does move at the speed of light. Because it is light. The lightning itself isn't traveling all the way to your eye, I'd hope.
I thought I was watching Vsauce for a second.
Flash must get bored of his power, I mean if he's going at lightspeed, He would see everything around him freeze in time as he ran "slowly" through it since his brain processes information at lightspeed, In fact a conversation with flash would sound greatly distorted since his brain probably picks up every small vibration that happens in milliseconds rather than merge the vibrations together to register as a sound...
+Chazz vc yea so if he ran somewhere at light speed he would feel like he was running like a normal person and for him it would feel like it took ages to get there, even though it would actually take no time at all
+james tiberius no and yes, imagine that you are in a space ship and you are slowly acelerating to light speed, as close as you get to lightspeed the time slows more for you, so if flash were running at a high speed like sound speed he would feel that he got there faster than he actually did because the time slows for him, but if he really can proces information at lightspeed he would feel like a normal person running at a normal speed but the world would be freeze
+Max Ayala * frozen
+Max Ayala your right but if he didn't process information at light speed, as he speeds up everything would be a blur and he would crash into things right away
He can control the speedforce so it isnt allways like that
i can see 120 fps
i think
OMG Im getting sort of addicted to these videos and Ive just realized that randomly Ive finally arrive at the fist episode! Why!? oh why!?!!!
I think the fps perception is more for quicker reactions not experience more of life.
Then you don't understand fps with higher fps, you literally get more frames of information and thus experience more of reality and life.
And it is because you have more information streaming into your perception that you have a 'faster reaction'.
Not true, does a squirrel experience more life than a human? or a fly experience more life than a squirel? maybe they will show this in the show. It's the term "experience more life". I don;t believe having a higher streaming rate of sight to the brain would have any affect asides from making you mad.
Bingo Heart
Does a squirrel experience more life than humans? No, because they have a shorter life span.
But do squirrels experience more life per second compared to humans? Yes, they do.
And why do you think humans will go crazy because of higher stream rate? Because us humans can only handle 60 fps.
But not squirrels and other animals, their brain and perception of reality is based on this higher frame rate.
Why do you think humans are so fascinated by slow motion imagery? Because it allows us to see how much of life, how much detail of reality we are actually missing out.
A life is a wife and kids. unless the flash can manage 2 at once he isn't experiencing anymore. I also understand that humans actually take .05 of a millisecond to actually process the information our eyes give us, and our brains make up the rest to make it seem like we are actually there. The flash altered genetics to perceive the world, he really isn't human and could no live a human life. Also his "speed" wouldn't either because we have an "atmosphere" that is thick. and his body is flat. he is not aerodynamic. Also, the flash would actually have an emotional sense of being "behind" because he is so fast. I don;t know, maybe they will continue the series to reach the later times of the comics where things get more interesting. Where the flash actually has no home since he is the only one in the universe that perceives the world so fast., he is so very alone.
Bingo Heart
Seems like you were never making a scientific argument in the first place, then there's nothing rational to argue about here, I take my leave.
oh great, here we go about seeing in fps again - some people are saying theres no visual benefit to having over 60 fps, whereas i myself can clearly tell the difference between 100 fps and 60fps as well as 40fps and 60fps, there is a big difference when youve stared at a screen for longer hours than youve been doing anything else -- to be accurate, humans (and id assume all eyes) see everything instantly, not at a polling rate, and we, depending on the color, see the visible spectrum one color at a time and in order, with the latency being the distance from eye to analysis center, ie lime green is one of if not thee fastest color to detect, because it gets percieved before the rest of the colors - and closer distance from eye to analysis = faster perception, same reason dogs dart so quick, they can see your movements faster, plus are also lower to ground and its easier for them to move from stationary
60 fps?
Total bullshit.
+Alaska1925 yes its actually 60 fps i knew that before i watched the video i learned that on the science channel
Zachary Dixon Poeple do not see at 60 fps. If they did, then tell me, why is it that we can tell the difference between 60 fps on a screen and a higher refresh rate? Why is it that we can tell if a videogame is running at 120 fps or not? If we saw at 60, anything above it should look the same to us.
Also, every person has a different "cap".
+Alaska1925 We do not see in "frames" as each retinal ganglion cell is functionally decoupled from those around it, thus making information streaming to the visual cortex all happen independently per RGC with regards to the light stimulus, aka the brain doesn't receive spikes from all RGCs together 60 times per second as a camera would.
The two major factors that determine the temporal precision of the visual system are the absolute refractory periods of each synapse in the visual system, aka Photoreceptor>bipolar cell>LGN>V1>V2>v4>MT>MST>etc. The second, very broad, factor is the processing speed of visual information in the brain, which can fluctuate greatly depending on the level of attention to the visual system, or parts of the visual system. (This is such a very complex topic that it hardly seems fair to go into it via youtube comment).
Therefore, no the human brain does not see or process information at a static 60fps, it is MUCH more complicated than that, and to make it worse, the human brain does not even process the whole visual field to the same degree, with almost all of the processing strength being devoted to the fovea. (Again, a ridiculously complex conversation). We do know, however, that animals other than humans can process visual information at much higher rates than we do, so he isn't wrong there.
+Britt Yazel exactly!!!
+Alaska1925 I see 144hz. It's obvious when you compare it side by side.
Oh my... i just jump from latest episode (139) to this. What a change! Wow!
60 fps per seconds is bull shit because that is not how eues work
I agree, 60 is way too slow, but we do see things in FPS. Our neurons can send a signal around 268mph and there are about 7in between our eyes and occipital lobe. It would take a signal 0.00148sec, which works out to 674FPS.
nerd. go invent something for me to use.
I'll address your objections in the order they come in:
Do you have any evidence the neurons are not in a straight line? Our brains are incredibly efficient (in fact, they can perform around 2.2 PFLOPS and use only ~20 watts). It's really not a far leap to assume the neurons are in a straight line. The optic nerve (big bundle of neurons that our eyes are attached to) is actually a straight line as well.
The 268mph takes into account the lag at the synapses and is only an average.
Are you familiar with the concept of lightspeed? It's around 300,000,000m/s; any lag for light passing through something as small as an eye would be negligible.
You need to realize just how fast chemicals move around in our bodies. The only reason the electrical signals move as fast as they do is because of the speed at which sodium and potassium are able to move in and out of each neuron.
Oh no! I never knew I was a nerd!
wouldn't the fps entirely depend on how many photons are entering your eyes and not the the amount of time it takes for your brain to process them?
Really enjoyed this segment. Please keep them coming. Just the right balance.
Brains-->Kyle
Stopped listening when he said we see at 60 FPS. Completely incorrect. It is variable and we can see MUCH higher than 60 fps.
Meaning that any event occurring over that rate seems like a continuous blur, even if events happen in between frames. Nothing would be a blur to The Flash; he would be able to see every single frame of life without anything being stitched together by his brain. Everything over 60 FPS to us is a fluid vision that has to be interpreted and estimated and modeled by our brains. Sorry for the confusion!
That is a much better explanation.
Lol k bud
NERD!!!!!!
Alejandro Sanchez Well get of the channel if you dont like it
Mr. Hill this is exceptional. Thank you.
Did you know, that not only flash can move faster, his whole body has increased in speed, such as his thinking time, and probably that eye thing.
Watching this in 2018 is funny. I get a Vsaucey vibe at first lol. But Kyle definitely comes into his own as the series progresses. Yay for Science!
You talked about how the flash or other superhero’s that “phase” through objects or materials is really quantum tunneling. My question is, would quantum tunneling basically be teleporting so those super hero’s wouldn’t have to move through the wall they would just “teleport” to the other side, right?
Thinking at light speed is such an interesting concept.. Cool video!
Technically, people have been recorded to be able to perceive far higher FPS rates than 60 because we don't see strictly by frames. (Rods and cones and stuff) it mostly a matter of developing and training the eye to see it.
Could you do an episode on tachyons and the flash explaining the episode where Barry uses the tachyon enhancer and goes faster? I'd like to ask for a perspective with and without the speed force being a factor. Thanks!
If the flash percieves the world at lightspeed, and runs toward something at lightspeed, he would in fact, see it move. Because he's running into the light in transit, it would move...very slowly, but it would move, and if his brain can process information that quickly, he would possibly be able to notice those very minute movements. Light travels one foot every nanosecond. Assuming that it travels at full speed in his nerves and brain, which it must, then the connections between the cells would be amazing. It's possible he would see a few nanoseconds worth of movement from a human being, and actually be able to distinguish it. So the most amazing thing about flash, might not be that he sees the world standing still, but more that he doesn't. Just a theory.
The problem is that our eyes do not see in frames. Every cell of an eye recieves signal approximately 60 times per second depending on its' location, but all cells do not recieve these signals simultaneously. So we see a real life as a whole stream, not just several frames. And yes, a trained eye can tell the difference between 60 fps and unlimited fps if you are using 144hz monitor, i.e. that can display more than 60 frames per second.
2 questions about the Flash. 1. Despite his speed and information processing powers, wouldn't air friction still affect him? Running that fast seems like he would be burning himself up like a meteorite crashing through the atmosphere. Or a side note to that, could he breath oxygen that fast without super heating his lungs and burning them as well? What protects the flash from air friction? 2. Assuming the first question is answered, as the Flash runs around, he is still an object with mass, displacing air and other gasses as he moves through it. Wouldn't he be constantly creating sonic booms and turbulence that would destroy anything along his path like a tornado?
1. In the comics, the speed force, which he generates by running, protects him from dangerous problems that would otherwise kill him air friction and excesive loss of calories. 2. I believe the speed force also protects him from this. However if we're talking pure science then yes both 1. and 2. would happen.
thanks for the reply.
in the series on netflix he does in fact get set on fire from running fast his suit is actualy a new kind of firefighter suit star labs developed to earn back some reputations
Everything about flash movies at light speed, his inside his brain he's adapted to it

Also happy for Kyle on his new adventure
Thank you, I was just wondering about this myself. Now you've answered it for me! On to new ponderings!
Oh my god!!! I didn't know there were 85 of Because Science videos!
This channel is really neat. Thanks Kyle and Nerdist
Just discovered your show recently, I love it. Knowledge combined with humor, a great mix.
It is known that the flash can travel at trans time velocity which is unimaginable. Some comics state that he can run at 13 trillion times the speed of light which is still less but let's consider it for now given this speed and the constant speed of light Barry shouldn't be able to see anything while he's running because by the time the light hits any object and comes to him, he's not even there and it's impossible for light to catch up to him. So this would lead to 2 possibilities i.e., Either the flash has a different perspective of looking at the universe or the speed of light is only as fast as you can physically measure them. The faster you go light keeps up with you or its speed is infinite.
He blinded me with SCIENCE!
Congratulations for bringing science to those who without the linking to geek movies and cartoons would never get cloese to it.
However, as a comics fan, I think that some explanations are... Just because, just because the writer wanted it to be that way. If I create a character who can travel through mirrors, there is no explanation, it's just because it's the way I want him to travel.
I have a question. One of the problems of supersonic flight is the fact that airplanes have to fight against air friction, called drag. So then why doesn't that affect the Flash? Wouldn't the faster he go the more heat that he generates from the friction? Or, at one point wouldn't the air itself act like concrete at that speed?
Ahhhhhhhhhhhh!!!! Your hair! Your glorious hair! Where has it gone!
I am pretty new to the channel, and have only seen you with long hair, and didn't realize this video wasn't a recent one when I clicked it.
I travelled from the future to the past, to meet Kyle when he was pretty boy nerd, until to his eventual rise as Thor.
He looks a lot like that Australian doctor on house. Kinda amazing to see him go from that to Thor.
How cool is this!? love it, so glad you guys are doing this series : )
I think The Flashes does compensate for the choppy frames we would experience so that even at normal speed it seems contentious to him.
Watched your rick and morty episode and then this one.. was like watching jesus turn into a hemsworth brother. well played
The creepiest moment in the DC universe was when flash ran part superman, and superman's eye followed him.
Are you talking about in the movie Justice League? If so, that was an interesting part. I was wondering what was going to happen
He seems so calm
our eyes work very very similar to an h.264 codec, we get different blotches of colors and see them after a latency, in order - so if the flash traveled fast enough, he would see a persons single colored shirt shift becore their single color pants for example
So after watching this I go from thinking "The Flash is broken" to "The Flash is broken"
Holy canoli it's been four years since I watched this ep. I need more time lag going too fast!
