Each colored bar represents a photo being taken on the timeline. The light is shot through the bottle hundreds or thousands of times (6 times here for simplicity), and takes photos at intervals each time. By the end, you have a full series of images that you can string together into a movie ( in this gif it's the rainbow at the end)

The camera simply has an extremely fast shutter speed, on the order of picoseconds (0.000 000 000 001 seconds, or a trillionth of a second). It takes light 3.3 picoseconds to travel 1mm (actually slightly more due to lack of vacuum).

This means that the camera is able to open its shutter, take a photo, close the shutter, and reopen again in around 10-20 picoseconds. However, because the light would have moved nearly 1cm by then, the camera must go back and take a photo slightly ahead of time so it captures all the stuff it missed.

TL;DR version : science science voodoo hoola hoop

no necessarily. It's a complex process, but its not too dissimilar to a standard DSLR camera.

On a DSLR, if you increase the shutter speed, the image gets darker, since it has less time to let light in.

Similarly, since the shutter is only open for such a tiny amount of time, it only captures a tiny amount of light. So the same shot must be taken thousands of times, then those thousands of images are overlapped to produce one frame that's bright enough to see.

So the order in which the frames are captured might be : 1,3, 5, 7, ect. It must go over these frames thousands of times before there is an image bright enough to see. After those frames are done, it moves on to : 2, 4, 6, 8, ect and the same thing is done

as long as the bottle and the camera don't move at all, ideally photons will reflect the exact same way every time, making films like this possible to create.

However, you would not be able to take a video of, say, a car at the same speed (1 trillion fps). This is because the photons need to reflect of a stationary object (the bottle) millions of times, and hit the same point (the camera) every single time, at the exact same angle.

You could do the same thing with a bullet, although the resulting film would be nearly a year long at 1 trillion fps.

You really want to ask that question? Do you know how the human eye works? Or why objects have gravity? Do you know why blue is blue or red is red? There are things that people know and some people don't know. But everything can be answered through development. We develop answers, technology, theories, and questions to be answered every day. Think about it. You have access to all the information in the world in your phone. 30 years ago, that would have been witch craft. In a couple decades, cameras like these will be common knowledge just like cell phones and the internet.

The thing is. They do know, there is an answer. If not, how was it done. I'm not asking for someone to explain something that hasn't been invented yet, like time travel or force fields. I'm asking about this one camera that this team of engineers made.

Also, camera's like this won't be common in 30 years. In the 60's, a camera was made that could capture images in 1 millionth of a second. I don't see those around.

No, the light is shot multiple times and only a few frames are taken each time. This is because of the speed of the camera being slower than the speed of light, and also many things such as electronic latency and data production speed.

I have used the term 'round' to describe each time a beam is shot.

So in the coca cola video above, you are actually seeing many thousands of different beams taken at different times.

To help understand better, imagine taking a photo of tar dripping off a ledge. You come back a week later and take a photo in the exact same position, the tar has moved a slight amount. Repeat for several years and put the photos together, it will look as if the tar takes seconds to reach the ground. This is exactly the principle used to film the travel of light

i don't remember where exactly this happened, but I did see the initial talk given about it. In a dark room, some guys shot as close to a single photon of light from a laser pointer as they could, and then, with a camera taking 10 billion photos a second, they viewed the light as it traveled through this coke bottle. There are theories of how they can use this for seeing into rooms from the hallways, without blasting radiation into random locations, more efficient medical scans and other stuff. I'm getting a lot of use out of this picture recently.

Yeah let me tell you why that is ********.
You can only see things from the photons reflected from material. So you can only see the photon the moment it hits the camera. So no you can't see it travel you can only see where it is at the moment you measure it. Meaning the only time you would be able to see the photon is when it hits the camera. It is impossible to see it when it is traveling.

They send a pulse of photons. That is billions of billions of billions of photons. Not just one. What you see as light are billions of photons being reflected by the air, cola bottle or table hitting the camera. The light you see are photons hitting the camera or your eye that have traveled from the place that seems bright to your eye.

It is impossible to observe a photon traveling. You can only say where it started and where it ended. Everything in between is speculation, that we will never be able to see.

They calculated how long it would take to watch a bullet shot from a handgun at the same slow down, and it came out to be about 1 year. It would take 365 days to watch a bullet move if watching at this slow down.

in addition to reducing the temperature around the bottle it is very possible, since photons move slower in cold temperatures due to less energy. the slowest speed of light produced by this method is something like 30 mph at like 10 kelvin

Actually, some galaxies can move faster than the speed of light. If they're at the very edge of the universe, the space-time between them is expanding at a rate faster than light travels in the frame of reference of the universe, hence they are seen as moving away from each other faster than C in terms of the universal frame, even though technically, they aren't moving faster than light but when the space between them expands as well, there speed moving away from each other is greater than C, if that makes sense?

it is also a fundamental law of physics that you cannot go faster then light in any way
its simply impossible for an object with mass which galaxies certainly have
there is something wrong in your previous statement and although i am wrong with the past one (i researched it) you are to

i will bother to explain

E=mc^2 is right but it is incomplete
for the sake of this explanation we will put momentum as P (i am copying this from minute physics and they know their ****)

if you want the full story you will need to use the equation
E^2 = (mc^2)^2 + (pc)^2 like i said P stands for the momentum of the object
take away the PC and you get the energy of a motionless object
Take away mc^2 and you will get E=PC aka E=momentum*speed of light
because this can be made into a triangle (like a pytagoras triangle) you can never have an object with mass that has E=PC it can get close to it but never quite reach it
this is what makes objects to go as fast as light

True, that is the correct equation, but what you haven't taken into account with your argument is a few thing.

1) In real world examples, you genrally can't remove factor of m0. You can have a value of p equal to 0, but you can't have a value of m0 equal to 0 if you have a value of p in your equation (because if m0=0, p=m0*v=0) There are situations where you can such as with massless particles, like photons or gague bosons (you could argue that you could include gluons as well, but thats a different matter)

2) I never said the objects themselves were moving faster than light, in fact I specifically said they weren't. The galaxies are moving away from each other very fast, yes, but not at the speed of light. The thing that makes them faster than light in a universal frame of reference (thats a very important bit here, the fact this is being observed from the frame of reference of the universe) is the expansion of space-time between the objects adding to there apparent speed (as space-time expansion is capable of faster-than-light speeds) which means the objects themselves are apparently moving apart faster than the speed of light in the universal frame

3) This (space-time expansion) also allows faster than light movement of other universal objects, most notably space-time virtual points, which again, rely on the expansion of space-time between them.

But light is always the fastest. it just doesn't make a straight line, it basically bumps a tiny bit, but enough to make it look like it's slower from the outside. water has a refractive index of 1.33 so light will travel at c/1.33 in water. but the photon is still always traveling at c

ITT people not understanding the difference between framerate and the velocity of light.

the frame rate does not depend on velocity because it does not have a displacement component. The frame rate is based entirely on the interval between each frame (i.e it only has a time component and a unit-less 'number of frames' component). Basically, you just need a camera that takes multiple frames in the amount of time that it would take the light beam to travel from one end of the field of view to the other.

tl;dr Stop saying that this is impossible because "the camera needs to travel faster than light". that's not how it works.

P.S. what I believe the scientists did in this case was capture different portions of the light beam travelling at a time, then stitched it together to make a full video. Their system was fully repeatable, so they can record different portions of many identical light beams. this enabled them to emulate an even higher framerate than technically possible.
