The speed of light is about 300,000 kilometers per second. Did you know that electrons that use electricity also travel very close to this speed. Information traveling on the Internet also travels at that speed. Modulated information or electrons travel somewhere around 60% of the speed of light in most conductors.
WiFi signals, which travel mostly through the air, travel much closer to the speed of light than electrons moving through the copper wire. These signals can travel at the maximum speed of light recorded in a vacuum, which is about 185,000 miles per second.
Some calculations show that electrons can travel through a conductor at 90% of the speed of light. Imagine how fast these particles could travel in a vacuum. Much more energy is needed to make them travel faster. This is because the electron becomes much heavier as they reach the speed of light. However, the light moves at 186,000 miles per second in outer space. The outer space is considered to be empty. Light waves may be slowed by friction. Your sunglasses are capable of blocking UV light waves. In fact, many scientists believe that certain types of radiation are needed millions of years to escape the center of the sun after millions of nuclear reactions.
The speed at which it travels depends a lot on the medium by which it moves. Think of materials that light can't move. Light can never pass through lead or various types of metal. Light particles or waves try to penetrate these materials. However, they only reach the outer surface and become 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 that. The first law of thermodynamics is known as the law of conservation. This law states that energy cannot be created or destroyed in a contained or isolated system. The second law of thermodynamics puts an interesting spin on the first law. The second law states that the entropy of any contained or isolated system always increases.
The speed of light is measured at 186,000 miles per second. The distance that information travels over the Internet is thousands of kilometers in seconds. In fact, the time it takes to receive information is instantaneous. Of course, there are several devices that slow down the process, such as routers and various types of switches. However, the process that slows down this method of information travel is the speed at which humans make their decisions and are able to put their ideas online. Human ideas can turn the Internet into a good way to change the world. However, the Internet can also be a method of conveying bad ideas.
