Light travels about 30000km a second. That might sound great for us earthlings, for light'l take only 0.051s to travel from Tokyo to London[i.e.20times back and forth]. Lets think outside the box, or rather the globe. It takes light 1.28s to travel to the moon....so NASA scientists had to wait for at least 3s before they could recieve replies to their queries to people on orbit around the moon. Half an hour for a light pulse to reach Mars!! And yeah, light rays from sun take two whole days to reach pluto! And if thats not enough, you travel at light speed for 4.3 years and only then can you reach the star nearest to the solar system, The Proxima Centauri!! 100,000 years to travel across the width of the galaxy, and 100 billion years to travel across the observable universe.So, face it.....the speed of light is snail's pace for the Universe is REAL BIG!!
