Some writers have proposed that the pyramids were built using the power of sound, vibration, or magnetism. Several investigators, such as John Keely (1827-1898) and Nikola Tesla (1856-1943), have given us an idea of the possibilities of sound activating a power capable of lifting enormously heavy objects. The power of sound has also been stressed in theosophical writings:

We say and maintain that SOUND, for one thing, is a tremendous Occult power; that it is a stupendous force, of which the electricity generated by a million of Niagaras could never counteract the smallest potentiality when directed with occult knowledge. Sound may be produced of such a nature that the pyramid of Cheops would be raised in the air, or that a dying man, nay, one at his last breath, would be revived and filled with new energy and vigour. — The Secret Doctrine 1:555
