This book presents new theories and concepts in cosmology, physics and philosophy. Its main thesis is the unifulverse hypothesis, according to which, our universe could transform into different parallel universes. This implies that the laws of nature could change and the universe is a living organism, which evolves as living organisms do. The author also discusses diverse topics, such as reality and knowledge, and concludes that reality is a mathematical equation between the abstract and the concrete, while knowledge is a continuous process, instead of a static mental state. This book is useful for readers interested in science and philosophy, and widens the horizons of the interdisciplinary inquiries through its original scientific and philosophical ideas.
