Extrasensory awareness, also known as ESP, is the ability to perceive information without using the five senses. The term can be summarized by the crossword solution RADAR, which stands for Radio Detection and Ranging. RADAR is a system used to detect objects and measure distances by sending out radio waves and analyzing the reflected signals. This technology is similar to extrasensory awareness in that it can detect objects and measure distances without relying on the five senses.
