Light Year

In fact, when you come to calculate about existence, years cannot be used as a measurement, they are too small. A million years does not mean anything. When you start thinking about how old the solar system is, you have to use a new measurement which is not used ordinarily because we never come across such a big thing. And that new measurement is invented by physics: the light year.

You have to understand what a light year means, because our galaxy is millions of light years old. Light travels with a tremendous speed, the greatest speed there is. Anything traveling at that speed will turn into light. The heat of that speed is such that anything at that speed will become light. So there can be no speed greater than the speed of light. We cannot invent any rocket which moves faster than light, because then it will turn into light itself, immediately it reaches the speed of light.

The speed of light is 186,000 miles per second: per second, one hundred and eighty six thousand miles. In one minute, sixty times more; in one hour, again sixty times more; in one day, again twenty- four times more; in one month, again thirty times more; in one year, again twelve times more – that is the meaning of one light year. And our sun is millions of light years old.
