Special note from our technical staff:
You often see the words "anti-gravity" used in the descriptive title of many research papers and related projects involving levitation of objects using ion wind propulsion, magnetics, electrostatics and other forms of unorthodox propulsion means.
When you imply "anti-gravity" you imply taking the square root of a negative number. Even though this is done using the letter "i" as an operator, it cannot exist in the real world of physics as we know it today. An implication of negative mass or distances less than zero cannot exist in the event time frames of the real world.
