In his paper 'Extra-Terrestrial Relays,' Clarke accurately predicted the use of geostationary satellites for communication. This groundbreaking idea laid the foundation for modern satellite communication systems and earned him the title of 'Father of Satellite Communication'.

Clarke's science fiction often explored technological advancements that were then only theoretical, such as artificial intelligence, space elevators, and advanced computing. Many of these concepts have since become realities or are actively being developed.

Clarke formulated three laws that are often quoted in discussions about science, technology, and the future. These laws address the acceptance and understanding of new technologies, stating: " When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. " The only way of discovering the limits of the possible is to venture a little way past them into the impossible. " Any sufficiently advanced technology is indistinguishable from magic.
