Antiparallel vectors. In a Euclidean space, two directed line segments, often called vectors in applied mathematics, are antiparallel, if they are supported by parallel lines and have opposite directions. In that case, one of the associated Euclidean vectors is the product of the other by a negative number.
This is indeed levitation, but it is not anti-gravity. To understand this one has to clarify what we mean by Anti-gravity . Anti-gravity is an idea of creating a place or object that is free from the force of gravity. In simple terms Anti-gravity is generating a counter to Newton's law of gravity F=GmM/r^2.
