In fact, c stands for the speed of causality. But it is easy to say that it is the speed of light. It really is the speed of light. So why is the speed of light the speed of causality? Galileo stated in the principle of relativity that all experiments must have the same results under constant velocity. However, this principle of relativity does not determine the speed of light.

Suppose an electrician was following a ship carrying lightning. From Maxwell’s equations, the field strength of an electric field can be calculated from the total velocity of that electric person. So what is total velocity? According to Galileo, total velocity is the velocity of the electrician onboard + the velocity of the ship. Field strength is not a field. force electromagnetic force. This force is called the unregulated Lorentz force.

Galileo’s transformation states that total velocity is the sum of velocities that do not take into account the position and timing of the movement with the observer. When using Galileo Transformation, it works well for small velocities, but not for large velocities. Is Maxwell wrong or Galileo wrong? Galileo is wrong. When Galileo’s transformation doesn’t work, Lorentz reveals the Lorentz transformation. According to Lorentz, space and time are related to spacetime. It also uses the speed of light.

In Galilean Transformation, the speed of light is infinity. In Lorentz Transformation, the speed of light is a constant parameter. The Lorentz transformation can also explain the super-fast light velocity of Maxwell’s equations.

Maxwell’s equations find that the fastest speed is the speed of light. The speed at which electromagnetic waves are carried; The fastest way to get from one place to another in the universe. This is the fastest and unchanging speed as you look at it from a standstill and follow it with a beam of light. In addition, it is the speed at which only particles without mass can run. The presence of mass slows down the obstruction. The universal speed limit is not infinity just because there is mass. Instead of infinity, the universal speed limit is the speed of light. And it’s a velocity constant of causality. The main idea of E = mc² is that you can change the amount of energy from a small mass to a large amount. c is a parameter that sets the causality speed limit.
