Pseudoscientist Semir Osmanagić claims a series of triangular-shaped hills in his native Bosnia, are artificial pyramids that are bigger and older than those in Egypt.
Despite mainstream archaeologists saying they are just natural rock formations, Mr Osmanagic has made another bold claim that he has found Nikola Tesla’s so-called "torison fields of standing energy" at the Bosnian Pyramids site, which means we could now "communicate with aliens".
Mr Tesla was a Serbian-American inventor, physicist, and futurist, who contributed to the design of the AC electricity supply system in 1888.
His ideas became more left-field and experimental towards the end of the 1800s, and he devised the theory of "standing waves" of energy coming from Earth that meant electricity could be transmitted wirelessly over long distances.
Mr Osmanagić has claimed the alleged discovery at one of the "34,000 year old" pyramids he calls the Pyramid of the Sun "changes the history of planet" and could lead to intergalactic communication.
He wrote: "The discovery of Tesla’s standing waves at the top of the Bosnian Pyramid of the Sun— which are believed to travel faster than the speed of light, while not losing strength as they pass through cosmic bodies—prove the existence of something referred to as a cosmic web or cosmic internet which allow for a immediate intergalactic communication throughout the universe.
