    A new camera developed at the University of Quebec shoots at 10 trillion frames per second :eek:.

    It is so fast that it can film light beams moving in slow motion. You can see for yourself (unfortunately the only video I can find is on Facebook) :

    If that really is the sight of light beams moving, then that really is an incredible thing to witness.

    Does it fit on the end of a selfie stick?

    Probably not the same video, it's 7 years old.

    Impossible, as it was last time this claim was made

    So...the camera can take pictures of light moving in real time. But cameras create images using, err, light. The camera can't see light while it's happening, it can only see light that's already happened.

    Or something. But there's some bootstrappery going on here and I don't like it.

    It's a simulation, same as last time.

    If you turn on a torch in a foggy room, this camera would be able to see the beam of light sprouting from the torch, like a star wars lightsaber

    Nope, not having that sorry. No. No you can't have that.

    NoXion It's been 600 years...

    So it doesn't actually capture images of photons in flight, which would seem to be impossible. Rather that it's quick enough to actually show the torch switching on? I'm not sure if that's what you're getting at.

    Seeing photons in flight, in the same way you'd see bullets in flight, is impossible because "seeing" really means to detect photons, and given that photons do not interact with one another, the only way to detect them is if they interact with a detector, such as your eye. In a sense photons are invisible, but if one smacks into you head on, you feel its presence.

    Crispy's torch would produce a stream of photons, roughly going in the same direction, which if it were aimed perpendicular to your line of sight would be invisible. However they would bounce off the molecules of water in the fog, with some being deflected with an angle that sends them flying off into your eye, or a camera. With a fast enough camera, this scattering of the photons would occur slowly enough that the end result would look a light sabre powering up.
