Why Time Slows in Emergencies
To see if danger makes people experience time in slow motion, scientists at Baylor College of Medicine in Houston tried scaring volunteers. However, roller coasters and other frightening amusement park rides did not cause enough fear to make time warp. Instead, the researchers dropped volunteers from great heights. Scientists had volunteers dive backward with no ropes attached, into a special net that helped break their fall. They reached 70 mph during the roughly three-second, 150-foot drop. Volunteers estimated their own fall lasted about a third longer than dives they saw other volunteers take. To see if this meant people in danger could actually see and perceive more—like a video camera in slow motion can—Eagleman and his colleagues developed a device called a “perceptual chronometer” that was strapped onto volunteers’ wrists. This watch-like device flickered numbers on its screen. The scientists could adjust the speed at which numbers appeared until they were too fast to see. If the brain sped up when in danger, the researchers theorized numbers on the perceptual chronometers would appear slow enough to read while volunteers fell. Instead, the scientists found that volunteers could not read the numbers at faster-than-normal speeds. “We discovered that people are not like Neo in The Matrix, dodging bullets in slow-mo,” Eagleman said. -
