Telecommunications exist because the Normans wore stirrups at the Battle of Hastings- a simple advance that caused a revolution in the increasingly expensive science of warfare. Europe turned its attention to making money to wage wars. As mine shafts were dug deeper, they became flooded, stimulating scientists like Galileo to investigate vacuums, air pressure and other natural laws to mine deeper silver . This led to the discovery of electricity and magnetism's relationship and to the development of radio, and deep space telecommunications that may enable contact with galactic civilizations.
