Humans want to travel at the speed of light: When light is shining in the sky, first of all, we see the light of light and only then its thunder is heard. This means that the speed of light is faster than the speed of the sound. Scientists have achieved the speed of sound, but just getting the momentum of light is a bit weighed.
There are many missiles, whose firepower is faster than the speed of sound. There are also fighter aircraft that fly faster than the speed of sound. But human wants to drive the car at the speed of the sound, just walk and the train runs. Although it has also succeeded in some extent and now it is a desire to have a space-laden space plane.
The speed of light is so high that it will decide the distance from London to New York to more than 50 times in 1 second. If sending such speed messages, sending messages to Mars will take 12.5 minutes. Now if we have to return to Mars, we have to achieve the speed of light otherwise we can go but there is no guarantee of return. Now you can add how much time will it take to go 22 million kilometers if we go at a speed of 1,000 kilometers per hour ....
What is the speed of light: The perfect speed of light in space-like vacuum is 2,99,792.458 kilometers per second. In the Rig Veda the speed of the sun's light has been almost the same. The average distance of the Earth from the Sun is about 14,96,00,000 kilometers or 9,29,60,000 miles, and sunlight takes 8 minutes to 16.6 seconds to reach the Earth.
The distance covered by light in one year is called a light year. A light year means approximately 9,500 billion kilometers. It happens speed of light
