Story summary

Brian Haidet, a Ph.D. in Materials Science, has developed a camera that records video at 2 billion frames per second.
The camera lets viewers see light in motion and "see the past," demonstrated on AlphaPhoenix by recording a laser reflecting off mirrors.
When repositioned closer to the light source, the outgoing light appears to move slower than the incoming light, reinforcing the speed of light as the universe's limit.
