The speed of light is approximately 300,000 kilometers per second. You know that electrons that make use of electricity also travel very close to that speed. Information traveling on the Internet also travels close to this speed. Information or modulated electrons travel somewhere around 60% of the speed of light in most wires.
WiFi signals, which travel mostly in the air, travel much closer to the speed of light than electrons moving through copper wire. These signals can travel at a maximum recorded speed of light in a vacuum of approximately 185,000 miles per second.
Some calculations show that electrons can pass through a wire at 90% of the speed of light. Imagine how fast these particles can travel in a vacuum. To make them travel faster, you need to use a lot more energy. This is because the electron becomes much heavier as they reach the speed of light. However, light travels at a speed of 186,000 miles per second in outer space. Outer space is considered a vacuum. So maybe the light waves slow down by friction. Your sunglasses are able to block UV rays. In fact, many scientists believe that it takes millions of years for certain types of radiation to escape from the center of the sun after millions of nuclear reactions.
The speed at which it moves is very dependent on the medium through which it moves. Consider that there are materials through which light cannot move. Light can never pass through lead or various types of metal. Light particles or waves, try to penetrate these materials. However, they only strike the outer surface and are converted to kinetic energy. This means that they heat the surface of these materials and dissipate into nothing. Maybe they become potential energy. The laws of thermodynamics would indicate this. The first law of thermodynamics is known as conservation law. This law states that energy cannot be created or destroyed in a restricted or isolated system. The second law of thermodynamics puts an interesting twist on the first law. The second law states that the entropy of any contained or isolated system is always increasing.
The speed of light is measured at 186,000 miles per second. The distance that information travels on the Internet is thousands of miles per second. In fact, the time it takes to receive information is instantaneous. Of course, there are different devices that slow down the process, such as routers and different types of switches. However, the process that slows down this method of information travel is how quickly people make decisions and are able to bring their ideas to the Internet. Human ideas can make the internet a good way to change the world. However, the Internet can be a method of conveying evil ideas.
With best wishes.
