Nikola Tesla was a visionary inventor and electrical engineer whose work in the late 19th and early 20th centuries laid the foundation for modern power systems. Born in 1856 in the village of Smiljan (modern-day Croatia), he was an ethnic Serb and a subject of Austria-Hungary. While the term "Yugoslav" became common later in his life to describe the unified South Slavic state, Tesla famously expressed pride in his "Serb origin and Croat homeland."

He is most celebrated for developing the alternating current (AC) motor and the polyphase system, which defeated Thomas Edison’s direct current (DC) in the "War of Currents." Beyond these practical achievements, Tesla was a pioneer in wireless communication and theorized about a "World Wireless System" that would provide free, wireless energy to the entire globe by using the Earth’s ionosphere and ground as conductors.

Nikola Tesla's "Otherworldly" Concepts

• Wireless and "Free" Energy: Tesla’s most ambitious project was the Wardenclyffe Tower. He believed he could transmit power without wires by making the Earth and its atmosphere resonate at specific frequencies. While often interpreted today as "free energy," Tesla’s goal was a global distribution system that was efficient and potentially limitless, though it lacked the commercial viability required by his backers at the time.
• Contact with Other Planets: In 1899, while at his laboratory in Colorado Springs, Tesla recorded strange, rhythmic signals on his equipment. He was convinced these were not natural noise but a "greeting of one planet to another," specifically from Mars. Modern scientists believe he likely picked up radio waves from Jupiter or early wireless experiments by Marconi, but Tesla remained certain of their extraterrestrial origin until his death.
• Dimensions and Non-Physical Phenomena: Tesla frequently spoke about the universe in terms of "energy, frequency, and vibration." He was fascinated by non-physical phenomena, once stating that science would make more progress in one decade studying the non-physical than in all previous centuries. While popular folklore often links him to "other dimensions" or time travel, his own writings focused more on the idea that the brain is a "receiver" of a universal core of knowledge and that the universe itself is a unified field of energy.
