The arrow of Time

                                                   The arrow of Time                          Hello friend, have you ever thought why we are able to remember our past only. Why the time goes to end? We have some scientific theories to understand this system.               In the universe, there are at least three arrows of time- 1. Thermodynamic arrow of time. 2. Psychological arrow of time. 3. Cosmological arrow of time. Thermodynamic arrow of time: It is something related to the second law of thermodynamics which says that the entropy of a system always increases. And there present many disordered states than ordered once. Suppose you have a jigsaw in a box. There is only one certain ordered state o...

Anthropic Principle

Anthropic Principle                    Anthropic principle tells us about the universe after big bang. Why we exist in the universe? Anthropic principle solves such kind of questions. There are two versions of anthropic principle, weak and strong.               According to the weak anthropic principle, in this infinite universe, the conditions, necessary for the development of intelligent life, will met only in few regions. The intelligent beings in such regions should therefore not be surprised if they observe that their locality in the universe satisfies the conditions that are necessary for their existence. It is a bit like a rich person living in a wealthy area not seeing any poverty.            One example to use of the weak anthropic principle is to explain why the big bang occurred about ten thousand million years ago, it takes abou...

The Boundary Condition Of The Universe

The Boundary Condition Of The Universe                       Welcome friends, we will describe here the boundary condition of the universe. In this theory, we can solve many our difficulties about the universe. We all know that the universe was completely in ordered state in its origin as we have described in arrow of time . But why should it be at complete ordered state? Why was it not in the state of complete disorder at all time? And why is the direction of time in which disorder increases the same as that in which the universe expands?                                It seems that the universe evolves according to well defined laws which we can be discovered and understood. Can’t we think that the similar rules will work at the beginning of the univers...
