NASA Armstrong Fact Sheet: Sonic Booms
www.nasa.gov/c...
"A sonic boom is the thunder-like noise a person on the ground hears when an aircraft or other type of aerospace vehicle flies overhead faster than the speed of sound or supersonic. Air reacts like a fluid to supersonic objects. As objects travel through the air, the air molecules are pushed aside with great force and this forms a shock wave much like a boat creates a bow wave. The bigger and heavier the aircraft, the more air it displaces."
Ultrafast Camera Captures 'Sonic Booms' of Light for First Time
www.livescience...
"Just as aircraft flying at supersonic speeds create cone-shaped sonic booms, pulses of light can leave behind cone-shaped wakes of light. Now, a superfast camera has captured the first-ever video of these events."
Scientists Capture a "Sonic Boom" of Light
www.smithsonian...
"Choi reports that optical engineer Jinyang Liang and his colleagues fired a green laser through a tunnel filled with smoke from dry ice. The interior of the tunnel was surrounded by plates made of silicone rubber and aluminum oxide powder. The idea was that, since light travels at different rates through different materials, the plates would slow down the laser light, which leave a cone-shaped wake of light."

100 billion fps it would take a bullet 50 years to go passed the screen
gregistopal where dis you get those numbers? Bullet velocity varies widely depending on the caliber, screen of what dimensions, or did you just make them up?
Maybe the velocity, and distance traveled are obvious to him, like a 1800 ft/s 20 gauge slug moving across 2.35 feet. I don't know, but it might be closer to a 2500 ft/s NATO traveling across a little more than 3 feet. Granted you would need a fourty inch screen playing at 64 hertz.math is fine, but roughly rounded.
gregistopal I just calculated that assuming 60fps on the playback, 1 second of recording ≈ 52.85 years. I doubt a bullet would have taken anywhere near a whole second to go by the screen. It might be on vid a couple weeks to a couple months tho
Coltin Yancey He was making a joke fuckin hell.
lol screen dimension would have nothing to do with it... maybe aperture size, focal length, or lenses used when shooting. but it would take the same amount of time for a video of a bullet to cross the screen wether it was 10 " or 10'
Real time filming of chemical reactions. Watch bonds being broken and reorganized.
Darryl Landry It can't see molecules
Yet. :)
That would absolutely be amazing
There is already video of bonds forming. Grainy video to be sure. This new camera will collect some truly amazing sights.
Such techniques are actually being used as we speak. It's kind of weird, if you think of it.
There is a thing called Cherenkov radiation, which (as I understand it) occurs when you try to push gamma rays through a non-vacuum medium. The problem is that a photon really CAN'T slow down - but it also has too much DeBroglie (virtual) mass to travel that fast through that medium. So it splits the gamma photon into a gamma photon of lower energy and a photon that appears blue (i.e. the photon that holds the incremental energy that got bled off by the gamma photon trying to shed energy.) If anyone remembers the old James Bond movie "Dr. No" - the reactor was immersed in water as a secondary moderator (mostly to kill the alpha and beta emissions, probably) and when they fired up that reactor, it showed the blue Cherenkov glow. I don't know who in the movie's special effects team knew enough to do this, but for once a movie came close to reality.
Cerenkov radiation phenomenon can be found in the water around by a nuclear reactor. Light slows down to 0.75c or so, beta particles travel faster than that and there's basically a lightboom! But not beyond c though.
100000000000fps @ 4K would be awesome
+The Helghan Empire slow?
what do you mean
Porn
+TheMinipasila Generally high-FPS cameras are used for slow-motion video. If you record a 120 FPS video and play it at half speed, it'll be playing at 60 FPS, which is still smooth. If you record a 100 billion FPS video, you can slow it down as much as you want with it still being a smooth video: you'd need to have it play 1.67 billion times slower for it to play at around 60 FPS.
+Gex9z well there are already 180 hz monitors.. for like games high fps is good and it would be nice to see 120hz videos at somepoint in the future, 60 fps i think isnt enough yet. though 100 billion fps would be pretty stupid to play at 100billion fps...
do you know how much space you would need to store that video? we're talking petabytes, maybe even exabytes of data just to record for a few seconds.
this is the stuff we should be funding we could potentially see neurones fire that's absolutely amazing
This has actually been successfully accomplished. However, achieving this feat was only made possible by using Democrat brains for testing, since those house roughly half the neurons of a typical brain, and their pulses travel at a mere fraction of the nominal speed.
Science doesn't lie.
We arent "slowing down" light. Just redirecting its path to be a longer one leading to a longer travel time.
I was just scrolling through to see if this comment existed before I made one, thank you!
Unfortunately that's not what is happening, the speed of light is constant to your frame of reference. Or in other words from your point of view. So Coltin is correct, all we are seeing is light traveling a longer path in the plate material, vs the "tunnel" where the photons are less obstructed. You should check out PBS Spacetime, they have numerous videos that better explain scenarios dealing with the speed of light, or the speed of causality; as they refer to it.
pure spectrum of light is constant it's neither slow or jumps to fast. it justs get reflected and redirected else where.
What? 😆
Coltin Yancey no light slows down if it enters a more dense medium
This comment section is filled with scientists and geniuses. lol
Zedekiah Zelkova you mean all the 10 year olds thinking that they can win a nobel prize by commenting tat its dumb to get things faster then light if you can increase light speed and thus its max speed?
(wich is inpossible lol)
inpossible in 2k17 LUL
Am I the only one who thought of the game "Sonic Boom" when I watched this? That game is terrible...
Zedekiah Zelkova it's not, not anymore
Zedekiah The Prophet Of Time I'm the REAL jenius.
The slow mo guys need that camera
They already made video about that.. 10 trillion fps
Moon Eye The comment was made 2 years ago
I don't think this camera is new. There is a TED talk about 1 trillion frames per second camera from years ago.
"This is not really one trillion frames per second. Instead, this is more like a strobe effect. You have seen this, right? You know, you take a strobe light and shin it on a guitar string or something. If you get the frequency of the light just right, it will show images of the string at different positions during it’s oscillation. In the end, you get a video that looks like it is slow motion but it isn’t. Actually, with the strobe light you can see this in real life without even using a camera. In this trillion fps camera, the light is just like a strobe light. It uses a pulsed laser."

TheLance3185
You're a naive idealist. Get accurate.
Yeah. Streak cameras have been around since the 70s. This 'new' camera is a multi-frame streak camera.
Light does not actually slow down when passing through the medium. The pilot wave each photon is riding is altered by the Super position of the photon. Meaning, when you pass light through a medium, depending on its characteristics, the possible positions of that photon in space, become multiplied by a new dimension. The dimension of that medium. Photons exist at Zero and One at the same time. If you add a dimension of obstruction, those photons still exist at 0 and 1, you just altered the 1.
Zenn Exile Interstellar was a good movie
Are you talking about pilot wave theory? That hasn't really been accepted yet.
wut?
I don't watch commercial films. They are superbowl adds that last 2 hours... and I don't need to be emotionally manipulated into buying consumer trash. If I want to watch toy commercials I just watch cartoons.
Zenn Exile your children must be prodigies
If nothing can go faster than light, just make the speed of light faster, thereby increasing maximum speed.
I don't know if you're joking or not but if you're not I regret to tell you it doesn't work that way.
I think it's a reference to something but I don't quite remember.
Lochie S Never tell me the odds!
"....but this one goes to eleven."
Light speed is intrinsic buddy.
What one can do with this camera?
Making the most slowed down version of 'coolguys don't look at explosions'...
Can you imagine how smooth the 2 sec explosion would look - stretched to 3 hours?
Christopher Zajonskowski 2 seconds would be more like 2 years with that camera
thought so - but was too lazy to do some math ^^
david noian much longer that that.
guess somewhat in the realm of 100 years at constant ~40 frames?
(still too lazy for calculator ^^)
Christopher Zajonskowski won't work, because the camera only records on row of pixels every time. oh would need thousands of konsistant explosions to record a video.
could they possibly observe the double slit experiment with this?
The photons would need to hit the camera to be seen, in order to hit the camera they have to not go through the slits.
lol, you don't seem to understand the experiment.
to "observe" means to have at least a photon being absorved by/interact with a detector, and by the time that happens that photon will either already have passed through the slits and hit the wall (where the detector is) or already have hit the detector inside/before it passes through the slits (if you put the detectors in there instead), so....
I have questioned that so much in my life... I honestly would love for them to film the double slit experiment with their camera. Great Idea Bro!!!
I’ll show you my single slit experiment
Photonic Boom is my ELO tribute band.
that framrate is probably more than enough to capture glass shattering with incredible detail
Additionally there is Cherenkov Radiation, which is basically the same principle and happens in most nuclear power plants.
The amount of memory that pc would have to have.
Isn't charikov radiation basically a photonic boom?
Zach Crawford i think so
Yes.
cherenkov. And yes. Good that SOMEONE else realized that there's nothing new about this and it's not the first time ever of anything.
Photonic Flash?
Subliminal light for capturing plasma filament creatures that travel faster than we see around intense electrical storms! If it's digitally captured then storage is possible for 30 seconds
The slowmo guys would be very happy
I would LOVE 😍 to watch a lightning storm with that camera! 😱🙌📹☁💧☔🌌
youd watch it to the end of time
this camera can capture image 100 billion fps, and that isnt faster than light?? seriously, i had this question for a long time
how this camera works?
Calvin Franca great thinking....did u got an answer...?😊
Calvin Franca me too
Calvin Franca the camera captures a series of same event to make a video and this talks 12min to 2hours
nothing can travel through *space* faster than the speed of light, the camara isn't moving. Actually, I'm not sure if I understood your question.
tomasgonzales i know this is 8 months ago, but the shutter speed on a camera that goes 100 billion fps has gotta be rediculous
For me, the most amazing thing about this clip is that they've made a camera that can take 100 billion photos per second! WOW!! That fact alone is AWESOME!! Photographing that boom must be a cinch!!
I want to know more about this camera. Does it actually capture video in real time sequential frames? Or is it a composite video file of many attempts?
Okay so if a jet goes fast enough it makes a sonic boom. so does the light make a boom sound? or is that you need more mass. does light weight anything?
someone answer please
Jose Ramirez
Light is a photon, a little packet of pure energy as such it has no mass, but can to converted into mass in under some circumstances.
As for the sound I cant say positively but I doubt it doesnt make a sound as radio waves are a form of light wave and are well known to carry signals used in the creation of sound
+Coltin Yancey Well it wouldn't make a sound though. EM radiation is just used to communicate between devices that make sound. It doesn't make sound itself, more like it "tells" the device what sound to make.
Photons have no mass. They do have momentum, that's why they can push stuff, but no, they have no mass.
light has weight any thing with mass can't escape a black hole
+Andrew Velasquez no, photons don't have mass
take more than 31 years to watch a one second event. :P
You could film the decomposition of a radioactive isotope that decays within milliseconds
You don't slow the light down -.- you increase its distance to travel making it take longer to get from A to B.
Trace! You're still my favorite!
Actually, the medium doesn't affect the speed of the laser. The reason light moves "slower" through a medium is NOT because it is slowing down, but rather because it is bouncing off the atoms and molecules in the medium, thereby making it travel a farther distance than, say, light moving through air.
nerd
Dash ToTheMax Hey, don't talk to your future boss like that.
Yeah, your'e probably right.
Actually, in a medium (like glass or water) light propagates slower because the electric field of light creates a disturbance in the charges of each atom (primarily the electrons) proportional to the electric susceptibility of the medium. The charges then radiate their own electromagnetic wave that is at the same frequency, but usually with a phase delay, as the charges may move out of phase with the force driving them, like a harmonic oscillator.
Incorrect.
If the "bouncing off" theory was correct the light coming out of the medium would no longer be in a beam, it would scatter.
You almost had me with the title. Sound --> sonic boom :: Light --> the big bang
So now, light can go faster than light. That's like everyone's running in their max speed and then somebody chugs a gallon of gatorade.
If I captured something at 10 billions fps I would play it at 10 billion fps. Imagine the smoothness
At a 60hz monitor...
Zoe Bonto 10 billion hz monitor ;)
I'd want one, please.
TheLegend 27 You should rather imagine the computational power required to even play at such a frame rate. The one you've seen is being spread out over time.
It's useless your eyes can't percive more than 3 billion fps anyway.
What now SloMoGuys?
It will be marvellous watching light beam passing through prism and separating spectrums
Just to be clear: the blue glow you can see around radioactive materials used in nuclear power plants is generated by electrons going faster than the speed of light in water.
So this is not the first detection of a "sonic boom of light". If it is a first of anything, perhaps it's the first time a "sonic boom" generated by a photon itself is observed. But that's not what your title says.
HE HAS THE CURIOSITY-BOX-SHIRT !!! AWESOME !!!
That's like how Rainbow Dash can do a sonic rainboom
That camera is so fast it can catch a crackheads blink.
Correction: you're not making light slower at all not even in a mynute little bit. What you are doing is causing it to bounce off of other things which just gets in its way and makes it take longer to get to point B. Since the fastest distance is always from point A to point B instead of going to point C first the light is still the same exact speed but has more obstacles to go around that is all.
Liking the shirt Trace.
My question is, how do we know that the speed of light is what we believe it to be? Did we take into account the trillions of tiny particles that exist in just 1 mile of space? How much does the gravity of the numerous solstitial bodies in our solar system effect light? If we measured light from two different points, one closer and one farther away from the source, how do we know if other sources of light did not contaminate the experiment thus influencing the time when point two perceived the light relative to the closer point one?
I guess this assumes that the speed of light was calculated based off of the delay between two points, and not just the amount of energy witnessed at a particular instance.... But I am still curious..
a. math
b. we do have a mirror on the moon to help with this.
With a camera like that I would watch a lot of explosions in slow-motion.
That was a play on words 0:31 saying you can make some light travel faster than other light. NO You can make some light travel SLOWER than other light. And a camera can’t move the speed of light. It CAN however take pictures set up along the course of where the light will travel hoping to capture (segments) of that lights travel, If that camera set up can move the speed of sound as the light is slowed down to the speed of sound.
when can i get that camera in my smartphone
You need even more chromosomes for this.
Kinda misleading though, since cherekov radiation is known for a long time, but I got what you said
One second of recording, would give you a video lasting longer than several years
At such high frame rate normal life stuff would look PAUSED all the time, such camera could be only used for light, perhaps.
Imagine usi8ng a slow-mo camera like that to record someone's death, then slowing it down so that moment the light leaves their eyes is extended to a week!
You could literally watch the very instant the person's life ends.
Femtophotography!
100,000,000,000 fps = one HELL of a money shot
I heard that light doesn't travel slower in water or glass or any other dense material, it just takes a longer path to exit it because of bouncing
Watch Trump beat Hillary in slow motion :)
@deharleyva 11 Months ago cmonbruh
Yeah I wanna see him take out his belt and say you're fired, then beat Hillary all the way to Mexico then build a wall. Best idea ever.
With a camera that fast I'd almost be able to capture my money going away!
almost. hahahaahah
camera snob: my camera is still better
Light doesn't slow down when travelling through a medium, it travels at the same speed, it just takes longer to traverse around all of the atoms and molecules and atomic structures in the medium.
Retired Astronomy Professor: Also check out Cherenkov radiation!
the light is not moving any slower, the beam is just taking a longer route. the light boom that you see is probably just the small amount of light that scattered off of particles and into the medium.
100 billion times per second huh? I'd use it to be able to watch my girlfriend's mood change in real time...
one beam of light is not "traveling faster than the other" it's more like the "slower" beam of light is traveling a longer road since it's bumping on the many particles of the medium in which it is traveling, so it reaches it's destination slower than the beam of light traveling in vacum
Hey, this would have been SO useful during my university project. We were looking at proteins in drosophila flight muscles in real time, and trying to track their movements, but it was impossible due to the rapid movement of the proteins compared to our microscope's frame rate.
watching paint dry at 1,000,000,000 fps would be so awesome :)
As I understood it, light is not going slower, its just taking longer to go from point a to b by taking a longer route.
This is the first step for The USS Enterprise to have a dash-cam. Just imagine those "true resolution" videos of light speed accidents in the future.
I do not want to be the guy looking for weeks through all the pics to find the 40 pics of light making that boom...
If I had a camera that shot that many FPS, I'd be going into debt trying to afford enough hard drives to store the video!
So finally i can have billions selfies
After watching for about a minute, I get a strong urge to read stuff in the comment section 😂
If I had a camera that captured 100,000,000,000 fps, I would capture a jet about to go supersonic and witness the process in slow motion.
I'm just trying to wrap my mind around how nothing is faster than light.....but here's a camera that can capture light moving.
Go-Pro... you've just been schooled.
id record my daily routine of pouring soy syrup paste on my silky body...a billion frames per second.
With a camera like that I'd be worshiped by the slow-mo guys😂😂😂😂😂😂
Damn, you scale up the experiment then a lower fps camera is acceptable.
Send that camera out on Starshot to image Proxima b as the probe is whizzing past, no? :)
You can't have different speeds for light in the same medium. The photons have a constant speed.
What about a sonic boom with gravitational waves. Would the mass increase and create a black hole?
I forget what it's called: the chemical clock where you can pour two clear liquids into a 3rd container, then take that third container and pour it into multiple other containers, and eventually, at the same exact time, they all turn black. Filming that would be awesome
I'd film this video and spend the rest of almost eternity watching you.
The Camera looks like it's been beaten with a sledgehammer
1 second of footage from that camera played back at 60 frames per second would run for around 52 years..
Didnt know a camera this powerful exist.
You aren't slowing down the light, you're extending the path of the light.
This isn't making some light go faster than other light.
It would take 132.12 years to watch that entire second at 24 fps... WTF?!
I thought the theory behind the super high fps cameras was the higher the frame count, the lower the resolution. 100b should be, like, indiscernable then, basic blobby shapes
What about the cherenkov effect ? Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The characteristic blue glow of an underwater nuclear reactor is due to Cherenkov radiation.
Hm I guess the key word here is "captured", because any Cherenkov detector functions by detecting the Cherenkov radiation (similar to the 'sonic boom' of light, as you call it) of particles that move faster than the speed of light in water.
I WAS LITTERALLY THINKING OF THIS 1 DAY BEFORE IT WAS UPLOADED
Take some videos instead of pictures and put them up in your house playing real slow, visitors will think they're photos but the next time they visit you all of them will be slightly different haha 😂
the light bloom and surrounding light appeared to be going at the same speed. or is that the light bouncing around appeared to go faster when it's actually going slowing it's obstruction?
The graphic at 0:28 showing the propagation of light through a medium is completely wrong. Light does not bounce around inside a material from one atom to another until it comes out the other side. If that were the case then the travel speed of light through a medium would be totally random. The correct interpretation deals with quantum fields creating drag on the light wave as it passes each atom.
I always like Seeker videos right before I see the video. I just know it will be great.
Photons is not slowed down by the medium. They simply has a longer path to travel. But the illusion of slowed down light is very much real.
100b frames per second I'd catch my wife telling me I'm right...
first thing i would do with it is watch tempered glass explode.
*Photonic Boom* Sounds really badass.
100 billion frames per second? MOAR PORN!!!
It's impossible to make light slower. What hours explaining is simply allowing like to hit multiple points of a mirror, fog, or some sort of prism, which results in the light taking longer to come out of the other side; however the light is still going the same speed. Just because the beam of light is bouncing off of a wall doesn't mean the speed has been reduced.
If aliens living 60 million light years away looked at us right now. They'd be seeing dinosaurs, maybe that's why they don't pay a visit...
I'd use the camera to tell the exact moment at which paint dries.
