  1.  Speed of Light — From time immemorial, it has been a scientific fact that of all things that have motion, Light is the one that travels fastest, at an unimaginable speed. But it was not until 1676 that science was able to measure the speed for the first time. 2. It will take a normal aeroplane about 17 hours to travel from one end of the earth to the other in a straight diameter. But it will take Light 0.03 seconds to do the same. 3. It will take the fastest aeroplane in the world (which travels around 3000 km per hour) about 7 years to travel from the Earth to the Sun. It will take normal aeroplane 19 years to do so.  It will take Light only 8 minutes to do the same. 4. Now let’s forget the aeroplane because it is useless inside the Space.  It will take NASA’s ‘Voyager’, 73 thousand years to travel from our Earth to the nearest stars called “Alpha and Proxima Centauri”. And this Voyager is the fastest Spacecraft that travels at 35 thousand miles per hour....
