Filmmakers on YouTube push boundaries, attempting to record light's rapid speed at trillions of frames per second.
=====================================================================================
In a remarkable scientific feat, the duo known as The Slow Mo Guys, Gavin Free and Daniel Gruchy, have managed to capture the speed of light on camera. This achievement, reported by New Scientist, was made possible through a collaboration with the Compressed Ultrafast Photography (CUP) team at the California Institute of Technology.
The camera used in this experiment was no ordinary device. Capable of filming at an astounding 10 trillion frames per second, it was 20 million times faster than their usual equipment. This speed was essential for capturing light, which travels approximately 186,282 miles per second.
The experiment setup involved passing a beam of light through a bottle of milk water. This arrangement allowed the team to observe the light's movement more clearly, as the light scattered through the medium, creating a visible path.
Once the experiment was underway, the camera captured the light as it traveled through the bottle. Each frame represented a very short time interval, with Free noting that each frame was about ten picoseconds apart.
The captured footage revealed the light moving from one side of the bottle to the other, a movement that appears instantaneous to the naked eye. When slowed down, the movement became visible, illustrating how light travels at incredible speeds compared to other objects.
This experiment showcases the team's creativity in using advanced technology to visualize phenomena that are otherwise imperceptible to humans. The Italian scientists' discovery has been hailed as "pretty awesome" by fellow scientists, marking a significant milestone in the understanding of light and its properties.
Moreover, this experiment led to an unexpected discovery. The Italian scientists turned pure light into a supersolid for the first time. A supersolid is a state of matter that becomes a solid crystalline structure, but also flows without resistance, a property known as superfluidity.
This groundbreaking experiment is set to open new doors in the field of physics, providing valuable insights into the behaviour of light and potentially paving the way for future advancements in technology.
