One day when niks was in school library, he saw a book which was about Understanding Our Universe. He also started thinking that how did everything began and how everything came into existence. He wanted to create a basic model of the universe so that he could be able to know more about our universe. He tried his infinity clock to help him giving information about the universe. But his infinity clock could only tell about the number of universes created or destroyed over a period of time or number of planets, galaxies or timeline of our Universe. It had no information about the birth of our Universe and it's structure. So niks had to try something else to solve this problem. He went to his room and grabbed his notebook and started solving some equations. He preassumed that our universe is absolute and took it as a reference. Further he also assumed that our Universe is at exact middle of the timeline between actual future and past. Assuming these, he got a structure which was similar to a trapezium. Basically it was a 3 dimensional structure having trapezium arranged one over other. The adjacent trapeziums were connected with millions of wormholes which appeared and vanished over time and had a shape of a funnel. He concluded that this was the pathway for time travel. There he found that there were infinite ways to travel into future but only one way to travel into past. This is because past is absolute and the present exists due to an absolute past. But future is undefined. Few timelines to future had more probability to travel than that of others. But he found that none of the timelines intersected each other but some had tributaries to more than one timelines which meant that our future can be changed over a period of time. Now the question was that when was Universe born and how did it come into existence. It was a confusing question to him. He was trying to find an answer to it. This time he used a method which he called "trail and error" method. He knew that Universe was so small in the beginning. It was a tiny ball which was so much dense. It contained only several gasses. It was million times dense than the black hole present in the centre of our Galaxy. He used thermodynamics this time. He assumed that due to high density the small Universe which he called "tiny-uniball" it's temperature rose with a high rate. and also the randomness was decreasing. So entropy was decreasing and thus keeping the internal energy constant or almost constant with respect to temperature and entropy, he found that the Gibbs free energy was increasing which should decrease for feasibility of a process, he concluded that it was the reason for the universe to expand. However it was not 100 % correct expaination but it was trail and error method which he used and added the data to infinity clock and rest of the information was given by infinity clock. Though finally he had a model of our Universe, But still he could not know that how did even that small dense tiny- uniball came into existence.
Next day he went to school and because of solving equations and understanding theories about Universe he couldn't sleep properly and hence he slept in class. His teacher came to him and asked, niks, "should I arrange a bed and pillow for you to sleep"? Niks (in deep sleep) was like," who the hell is trying to wake me up? I am tired, so just get lost." Everyone in the class started laughing. Teacher shouted in anger," niks get up and get out of my class". Niks woke up and asked in an innocent manner, what happened sir why are you shouting?" Sir said," just get out". Niks went out of class quitely and again slept on the ground outside the classroom. In this way, it was a "sleepy day" for him.
