Recording The Speed Of Light At 10 Trillion Frames/Second

March 28, 2019

Note: picosecond= one-trillionth of a second. A picosecond is to one second as one second is to approximately 31,689 years.

This is a video of the Slow Mo Guys taking a trip to the California Institute Of Technology (Caltech) in Pasadena to witness a camera there capable of recording the movement of light at 10 trillion frames per second. It's so fast you can actually witness light passing through a water bottle. Not my water bottle though -- you're not giving me light cancer just for the sake of your little video.

Keep going for the video, actual footage from camera (with water bottle composited in since the camera only records the light's movement) begins around 4:30. More footage afterwards around 11:00.

Thanks to Aaron and Lee, who both have names with side-by-side repeating vowels, which kinda blew my mind because it's a simple one.

    So, we can't exceed the speed of light but we can use a really fast camera to record it ... dammit universe! You make my head hurt!

    OK why couldn't they remove the water bottle label before doing this test? does the label on/off affect the outcome?

  • GeneralDisorder

    Before I go and watch the video I'm gonna go ahead and say it does not affect the outcome. The might have left it there for product placement. Or maybe... uh... To reassure the audience that it's an ordinary water bottle? I guess I'll have to watch the video now and find out.
