Bright Torch
The speed of light is 299,792,458 m / s. Scientists say it is the fastest anything can travel in our universe.
How can this be? If I was 10 yards away and shone a torch light in your face, the beam of light would travel to you online right at 299,792,458 meters per second. However, the photons in the beam would actually be the continuation of the journey (because of the waves, they travel along) and therefore would actually travel faster. Consider this: Let's say a car and a plane would go from A to B. The two are there at the same time. Imagine the plane moves the speed of light in a straight line. For the car to go to B in the same time, there would be faster than air travel because of all the twists and turns road, not to mention all the hills he has to go. Of course, this means that it is possible for a particle travel faster than the speed of light?
As strange as it may seem, the theory of relativity says that if you're in a car traveling at 200,000,000 m / s lights on, then the light of these lighthouses will a person standing still at 299,792,458 m / s and not 499,792,458 m / s. And if that person still shines a light your car, you will see her get close to light 299,792,458 m / s and not 499,792,458 m / s. The theory is so bizarre that many scientists have numerous experiments to test it. The most famous of these experiments is the Michelson-Morley. All experiments have confirmed that this strange prediction of relativity is true. Believe it or not!
