What If You Traveled Faster Than The Speed Of Light?
Life Noggin・2 minutes read
Light is fast, but can be slowed down in certain mediums, allowing particles to beat it in a race, leading to interesting phenomena like Cherenkov radiation. Researchers in Scotland successfully slowed down the speed of light in free space, opening up possibilities for new discoveries and insights into the nature of light.
Insights
- Light, composed of photons, moves incredibly fast in a vacuum at 300,000 kilometers per second, a speed so rapid that it allows for circumnavigating the Earth's equator multiple times in just a single second.
- Scientists in Scotland successfully slowed down the velocity of light in free space by utilizing a mask on an optical beam, altering the photons' spatial structure. This breakthrough could pave the way for novel revelations and enhanced comprehension of light's properties.

"Slowing Light Speed with Spatial Structure"
- Light is electromagnetic radiation made up of particles called photons, traveling at a speed of about 300,000 kilometers per second in a vacuum, which is so fast that someone moving at that speed could circumnavigate the equator about 7.5 times in just one second.
- While it's not possible to go faster than light in a vacuum, in mediums like glass and water, light can travel at slower speeds, allowing some particles to beat light in a race, resulting in Cherenkov radiation, seen as a bluish white glow in certain situations.
- Researchers in Scotland were able to slow the speed of light traveling through free space by applying a mask to an optical beam, giving photons a spatial structure to reduce their speed, potentially leading to new discoveries and a better understanding of light.
