摘要：
New images of black holes in recent times have created a strong validity of the Friedmann universe. Since the Friedmann universe possess singularity, synonymously black holes, its quantum aspect becomes more important for study. We have explored the Friedmann universe with reference to higher order gravity theory, a natural generalization of Einstein theory of gravity. Particle creation in vacuum space-time in the presence of strong gravitation field has been explained and thus emphasized upon gravitons creation as well as non-conformal invariance of the higher order theory in this context.
