The UQV theory is authored by Kedar Joshi. It is a (philosophy of mind) idealistic and (metaphysical) semi-solipsistic theory which contends that the sole reason behind the existence of the material universe is the vanity of its creator, the vanity materialized through 'the creator asking the created an apparently unanswerable ultimate question about the nature of the creator’s existence'. The material universe solely contains the non-spatial existence of the author of the theory. The theory is idealistic since it denies the reality of space and it is (metaphysical) semi-solipsistic since only two minds, viz. the creator and the created, exist. The creator is then supposed to be the ultimate questioner whose existential and intellectual vanity is the reason why the universe exists. The grounds for the theory are the NSTP theory and Vedic/Indian astrology. The UQV theory maintains that the nature of the birth horoscope of its author provides grounds for solipsism, and, on the basis of the idea of superhuman mind in the NSTP theory, it further conjectures the existence of the ultimate Being, the ultimate questioner, whose precise existential nature is the seemingly unanswerable ultimate question to be answered.
