Levitation
Levitation refers to raising an object against the force of gravity in such a way that it remains suspended without any physical contact. It is quite possible to do this without leaving the realm of physics, the most usual being magnetic levitation where the force of magnetism is used for this purpose. In terms of pseudoscience it refers to the ability to manage this raising by the power of the human mind. This has never been demonstrated — much less repeated — under controlled conditions and is consequently a pseudoscience.

Earnshaw's theorem
It turns out that Earnshaw's theorem is absolutely correct, but it has a couple of loopholes […] It turns out that precession (the rotation of a spinning object’s axis of spin) creates an island of genuine stability in a way that does not violate Earnshaw's theorem, but that went completely unpredicted by physicists for more than a century.
Physicists were shocked to find that levitation was a reality, all because of a misinterpretation of the theorem. The second loophole involved diamagnetism:
His theorem only applies to ferromagnetism, the common north/south pole type of magnetism found in most magnets. Diamagnetism is a purely repulsive magnetic force exhibited to varying degrees by all materials in the presence of a magnetic field. Simply drop a chip of graphite, for example, onto a block of magnets and it will float in midair forever.

Stage Magic
Levitation has been a long standing element of stage magic with various tricks being based on objects and people seemingly defying gravity. In reality these tricks uses things like strings or metal poles [3] to make something look like it's floating.
Judaism
Solomon's Carpet is an extra-Biblical Hebrew legend that King Solomon had a flying carpet that was 60 miles long by 60 miles wide.[4] Magic carpet
Christianity
Jesus provides the most well known case of levitation in Christianity by walking on water to his disciples. He is also mistaken for a spirit at first which gives another example of a levitating creature in Christianity.[note 1] More specifically, Catholicism considers levitation to be a symptom of possession by demons, and cause for exorcism.[5] Except when Jesus did it, presumably.
Islam
Solomon's carpet also appears in Qur'an 21:81 and Qur'an 34:12 according to Sunni Qur'an commentator Tafsir Ibn Kathir.[6]
