Why is the speed of light 299,792,458 meters per second? Why is the speed of light finite? Why is it exactly what it is? Does the speed of light always remain constant? What is faster than the speed of light? What is the speed of light in a vacuum? The speed of light in a medium. The speed of light in air. How is the speed of light known? How was the speed of light calculated? The movement of a photon of light in the Universe. What is the speed of light in water? What is faster than the speed of light? The speed of light and time.

If it is a massive particle, it can only approach this speed, but not reach it; and if it is a massless particle, it must always move at exactly that speed, but only if it is in empty space. The speed of light is not only the maximum speed at which anything can move in the Universe, it is also considered a universal constant. Whether we turn on a flashlight, look at the Moon or the Sun, or measure the parameters of a galaxy billions of light years away, the speed of light is the only thing that remains constant. But is this always true? That is why in our video today we will analyze many interesting questions: Why is the speed of light finite? Why is it exactly the way it is? Does the speed of light always remain constant? Moreover, today we will try to figure out - Does light move at the same speed all the time? And If something slows it down, will it remain slow after this influence disappears? And Will it accelerate back to its speed of light. Well, of course, we will figure out what influences all these crazy speeds and how in the end we know this. In addition, we will touch upon the history of the study of the speed of light, learn how the physics of light works, and how light moves in a medium. We will give examples of slowing down photons of light and accelerating them again to the speed of light. If you are wondering whether it is possible to exceed the speed of light, then watch the new issue! And if it is impossible to exceed the speed of light, then why!
