The natural gradual evolution in the human beings has stopped with the arrival of modern man. With the help of science and technology, Man has been making his own conscious evolution exponentially. With the possible reconciliation of General Relativity with Quantum Mechanics, he may arrive at the Truth of not only the 'how' but also the 'why' of the Existence. With the universal improvement of human EQs and EQs, one rational world-state may come into being ensuring optimal happiness and ideal autonomy to all its citizens with just and fair of share of not only every resource and amenity needed, but also of physical and mental health based on eugenics and ubiquitous eco-friendly environs.
