Researchers at MIT have developed a method to freeze a beam of light for 60 seconds at room temperature by firing a laser into a tiny crystal and hitting it with a high-frequency sound wave, which creates an acoustic shield that forces light into a hybrid state, stripping away its velocity without destroying its data; when the sound wave is turned off, the light resumes its journey perfectly intact, creating a 'pause button' for quantum data that could enable unhackable internet technology.

Why Scientists Froze A Beam Of Light #Shorts本站添加:
The beam of light was just frozen, completely [music] solid at room temperature for a full 60 seconds.
Normally, light blasts through a vacuum at nearly 300 million [music] meters per second.
If you try to block it, the photons crash into the barrier and vanish as heat. You can't just pause it. But researchers [music] at MIT figured out a way to trick physics.
They fired a laser into a tiny crystal and hit it with a high-frequency sound wave.
This acoustic shield forced the light into [music] a bizarre hybrid state, stripping away its velocity without destroying its data.
>> [music] >> For one entire minute, the light hovered in suspended animation.
When they turned off the sound wave, the laser resumed [music] its journey perfectly intact.
This breakthrough creates a pause button for quantum data, unlocking a future of unhackable internet.
The fastest [music] thing in space finally has a parking brake. Follow G Fun Facts for more.
