Scalar waves, also known as longitudinal waves, are a type of wave that differ from the more commonly known transverse waves like light and sound. These waves were first theorized by the renowned scientist Nikola Tesla. Unlike transverse waves, which oscillate perpendicular to their direction of travel, scalar waves vibrate along their path. This unique characteristic allows them to penetrate physical matter and travel vast distances without losing strength. Scalar waves are believed to have a range of intriguing applications, from advanced communication technologies to potential medical and healing treatments. Their mysterious nature continues to captivate researchers and enthusiasts, making scalar waves a fascinating subject in the realms of science and metaphysics.
