Early Attempts To Contact Aliens
31-Jan-09
I personally think that humans could do with improving how we communicate with each other before we sic ourselves on the rest of the universe. Just my humble opinion…
The desire to contact intelligent life on other planets is much older than the UFO craze and the SETI movement. Several 19th century scientists contemplated how we might communicate with possible Martians and Venusians.
These early proposals – which predate by 150 years the first extraterrestrial message that was sent in 1974 – were based on visual signals, as the invention of radio was still decades away.
