The universe is a strange and wonderful place, primarily empty space with a smattering of galaxies scattered about. Each galaxy has hundreds of billions of stars and the universe itself is so vast that it has one hundred billion galaxies. The enormity and scale is impossible to get our heads around and it takes rare geniuses like Einstein, Newton and even Hawking who have the uncanny ability to visualise, scrutinise and probe the depths and workings of the universe. Even the nearest star to us is 4 light years away, which in layman’s terms is a staggering 40 trillion kilometers, that is 40 with 12 zeros after it. The Voyager 1 spacecraft, launched in 1977 to study the solar system travels at 62,000 km/h. At this speed, It would take 73,000 years to get to the nearest star and a cool 640 million years to get to the centre of our galaxy!
