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...
Gravitational Force Hello friends, in this blog you will get to know about gravitational force. This force acts among all particles of the universe. Its range is infinite. Gravitational force plays a very important role in wide events of the universe like formation of stars and galaxies and their development etc. As you know there are four kinds of forces in our nature- Gravitational force, electromagnetic force, weak nuclear force and strong nuclear force. This is the universal force. Every particle of nature feels the gravitational force. It is the weakest force of nature of the nature but it affects the things which are far away. One more interesting thing about gravitational force is that it is always attractive. ...
Grand Unified Theory Hello friends, I have very interesting topic for you, Grand Unified Theory. This theory combine all the forces of our nature in spite of gravity. Let's start our topic- Friend, when the physicists observe the universe and work on their theories, they have to use so many rules. So they always want the summary of the rules. Summary means, they always want a united theory which consists some theories. Scientists did a number of attempts for the unification of electromagnetic force, weak nuclear force with strong nuclear force. They provide this theory (GUT) as a result of their work. Although this theory is not completely unified theory yet it may be a big step towards a fully unified theory. The strong nuclear force gets weaker at high energies. And electromag...
