I saw nothing in that linked video that suggested waves, so "clearly shows" is a decided odd claim. A trillion FPS is about 9 orders of magnitude slower than c and all the light signals reaching the camera come from the scene (i.e. stimulated emission). You can't look at light using light, in the same way that a passing spaceship can't see the light between the light clock mirrors.
I think you have not quite comprehended the basic process of vision. You cannot actually "see" objects, in that you are completely reliant on signals being sent to your eye. The scene image arrives at your retina upside down and your retina converts the signal to an electrical signal which is sent to your brain for processing and "viewing". When you move the laser pointer backwards and forwards fast enough it creates the visual effect of a line on the wall - this is similar in concept to a brand new invention called "moving pictures".. Turns out that movies are just a bit of a trick that utilises a limitation of human visual capture and processing.
By the way, all these light waves you've been seeing, by what fundamental method have you been detecting the light signal? By what method is light only and always detected?

Light travels about a foot per nanosecond. Clearly, MJV, you can't even do arithmetic. Did you read how the video came about?
The effective film speed is about equal to the speed of light. But don't let that stop your silly comments!MIT Media Lab's Camera Culture group wrote:Video of a fruit illuminated by a femtosecond laser pulse and captured at an effective trillion frames per second. Light moves less than 1 mm per frame.
We have built an imaging solution that allows us to visualize propagation of light at an effective rate of one trillion frames per second. Direct recording of light at such a frame rate with sufficient brightness is nearly impossible. We use an indirect 'stroboscopic' method that combines millions of repeated measurements by careful scanning in time and viewpoints.
The device has been developed by the MIT Media Lab's Camera Culture group in collaboration with Bawendi Lab in the Department of Chemistry at MIT. A laser pulse that lasts less than one trillionth of a second is used as a flash and the light returning from the scene is collected by a camera at a rate equivalent to roughly 1 trillion frames per second. However, due to very short exposure times (roughly one trillionth of a second) and a narrow field of view of the camera, the video is captured over several minutes by repeated and periodic sampling.

Your opinion is that everything is particles.
My opinion is that everything is waves. I win by proclamation.
I am just being silly, and so are you . . . X 10
