What is the speed of light and will humans ever be able to achieve it?

Speed ​​has changed the life of human beings and speed is changing. After getting off the bullock cart and horse, the person rode on a cycle. Then started traveling on a bike and now on a plane. Earlier it used to take 2 days to travel 100 km, now we can reach 100 km in 2 hours.

Speed ​​changed a person's life. The first letter used to take a week to reach 400 km, now if we mail, then in 4 seconds the person sitting 6 thousand km away will get it and if we do WhatsApp, it will be seen in 2 seconds. If you use mobile then in 1 to 2 seconds he will hear your voice. So it means to say that speed is very important in life. Due to this speed, earlier the future of humans was something else but now the future has changed.

Humans do not yet have enough speed to go to the moon and take a sip of tea and come back to earth in 1 hour. If someone has organized dinner on Mars in the evening, then return to Earth as soon as the morning. When this speed is developed, then the development we are seeing today will be many thousand times more developments. Scientists are working towards achieving such a speed.

Human wants to travel at the speed of light: When lightning flashes in the sky, first we see the flash of lightning, and only then do we hear its thunder. This means that the speed of light is faster than the speed of sound. Scientists have achieved the speed of sound, but now it is a bit difficult to achieve the speed of light.

There are many such missiles whose firepower is faster than the speed of sound. There are also fighter planes, which fly faster than the speed of sound. But human wants the car to run at the speed of sound, the bus to run and the train to run. However, he has also succeeded to some extent in this, and now there is a desire to have a space plane running at the speed of light.

The speed of light is so high that it will cover the distance from London to New York more than 50 times in 1 second. If this speed is to send a message, then it will take 12.5 minutes to send a message to Mars. Now if we want to return to Mars, then we have to achieve the speed of light, otherwise, we can go but there is no guarantee of returning. Now you can add how long will it take to go 220 million kilometers if we go at a speed of 1,000 kilometers per hour….

What is the speed of light: The exact speed of light in a space-like void is 2,99,792.458 kilometers per second. In Rigveda, the speed of light of the Sun has been told about the same. The average distance of Earth from the Sun is about 14,96,00,000 km or 9,29,60,000 miles and it takes 8 minutes and 16.6 seconds for sunlight to reach Earth.

The distance traveled by light in one year is called a light-year. A light-year means an estimated 9,500 billion kilometers. This is the speed of light. It has a formula - 9.4607 × 10^ 12 KM (nearly 6 trillion miles).

According to physicist Albert Einstein's proposition of special reciprocity, on which important of ultramodern drugs is grounded, nothing in the macrocosm can travel faster than light. The proposition states that as matter approaches the speed of light, the matter's mass becomes horizonless. That means the speed of light functions as a speed limit on the whole macrocosm. The speed of light is so inflexible that, according to theU.S. National Institute of Norms and Technology, it's used to define transnational standard measures like the cadence (and by extension, the afar, the bottom, and the inch). Through some tricky equations, it also helps define the kilogram and the temperature unit Kelvin.
