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...

The No Boundary Condition Of The Universe

The No Boundary Condition Of The Universe                             Hello friends, in this blog we will discuss on the no boundary condition of the universe. At first, I would like to introduce you from the topic. No boundary condition means a limited space-time. Actually we have some theories that predict the starting of the universe. Let’s discuss on it-                           If we talk about the classical theory of gravity, we find that there are only two ways of starting of the universe, either with the starting of time or with infinite time. But if we talk about the quantum gravity , it shows another way of beginning of the universe, in which the time direction is on same footing as directions in space, it is possible for space-time to ...

Strong Nuclear Force

                                         Strong Nuclear Force                          This is the strongest force of all four kinds of forces. It is carried by spin 1 particles, called gluons, which interacts only with itself and quarks. Spin 1 particles are like an arrow which looks same if one rotate it 360 degrees [fig(1)].                        You must have heard about the nucleus of atom which contains some protons with positive charge and some neutrons with neutral charge. You should think that the nucleus contains many positive charges but how it is stable because among the same charges, there should be repulsive force. Actually strong nuclear force works to hold them together. According to the new scientific theories, The protons are ...
