Gizmodo:
Everything’s cooler in slow motion, but high frame-rate photography is an essential tool for scientists studying phenomena that occur in the blink of an eye. Researchers at Lund University have just revealed the fastest high-speed camera ever developed that can capture the equivalent of an astonishing 5 trillion frames every second, fast enough to visualize the movement of light.
At those speeds, events that take place in as little as 0.2 trillionths of a second can be documented and studied at a speed that humans can comprehend. To help demonstrate just how fast that really is, the researchers used the new camera to film a group of photons traveling about as far as a piece of paper is thick, making it seem as if the light particles were barely moving, instead of racing past at 671 million miles per hour.
I’m always fascinated by this completely out of reach technology.
Bullshit clickbait title, after reading the explanation it’s like only 1.25T frames a second! fake news!
I think there is something misleading about it though. Unless the camera can actually take 5 trillion photos, it can’t take 5 trillion in a second. It can takes a certain number in a certain timeframe. The amount of time to take 5 trillion must include how long it takes to save the pictures, free the memory, and take some more.
That’s like the old joke where you tell the officer you couldn’t have been going 65 miles per hour because you weren’t going to be driving that long.
Just for a bit of perspective, light moves approximately a fifteenth of a millimeter in a five-trillionth of a second.
