How fast can you run?
10 Km/h, 20 Km/h ….or faster?
Imagine the fastest speed that can be achieved in space?
it’s 300000 Km/h, the speed of light.
![No matter how far away we look into the distant Universe, the physics governing atoms, and therefore... [+] our definitions of length, time, and the speed of light, are exactly the same.](https://thumbor.forbes.com/thumbor/960x0/https%3A%2F%2Fblogs-images.forbes.com%2Fstartswithabang%2Ffiles%2F2017%2F05%2Fheic1711b-1200x1345.jpg)
- Light, no matter how high-or-low in energy, always moves at the speed of light, so long as it’s traveling through the vacuum of empty space.
- By passing that light into a non-vacuum medium, you can change its speed so long as it’s in that medium.
- Light of different energy will change its speed by slightly different amounts, depending on the properties of that medium.
- Once you leave that medium and go back into a vacuum again, that light goes back to moving at the speed of light.
