How does the universe work?

How universe works? We can say the above as ‘How nature works’? The concept of Big Bang is theoretically as well as practically correct thing. But it is not a full pledged answer for understanding the whole universe. Universe has actually no beginning and end. It is the routine process in its course. ‘There is a universe in an atom’ We know how an atom works. Expanding and shrinking is its continuous process. In the same way the universe works at cosmological level. Atom is small, so that we can easily identify its function as not in the case of whole universe. Universe is, in fact, a big atom. Now what we are seeing is that the universe is in its expansion. After some period (million or billion years) in a certain condition it will shrink. This is the routine work of our universe. When it shrinks, everything would change that what now we are seeing in our universe. We may say it as collapsing swtage of universe. Then the Universe will halt or stop at one point. At the time the universe will be as ‘One’ or ‘Nothing’. It needs such halt to regain its energy to move forward or outward. Quantum Theory is also theoretically and practically a right thing but not a full pledged theory to explain the things that we want to know from science. In a small level it is good to understand the concept of function of energy. Universe is not in random. It strictly follows a rule or law to function well. Nothing in our universe can deviate from this law, whether it is in earth or space in over all view. We may call it as ‘Unified Theory of Universe’. These details are not discovered or invented by me. It was questioned and answered with solid evidences by our ancient scholars. They have apparently explained through their art works like paintings, sculptures and writings as proverb and scriptures. But these things have been misunderstood by the followers of such things. I feel, it is the right time to understand the true knowledge of our life, universe (God or Creator) and everything. A scholar said that ‘Do not do what it is already done’.

This activity introduces the students to an interesting puzzle. A student worksheet and solution sheet are provided. Suggest to the students that scientists have travelled to a distant galaxy and brought back these observations as part of their scientific investigations. The students' task is to propose a theory for what the basic building blocks in the galaxy are and what the rules are for how they connect. Be certain to clarify any questions about the shapes provided and the goals for students. Following this introduction and clarification have the students work in small groups to discuss their ideas. Finally, have the students present their theories to the class as a whole. Focus in on a discussion of strengths and weaknesses of each theory. One possible solution to the puzzle is included here, but remember there can be other valid theories. Finish with a discussion of what makes one theory better than another. Generally, if two theories explain the observations equally well, the simpler one is most widely accepted. This, of course, does not always mean the simple one is the correct one, but it may suggest a new generation of experiments. This activity generally takes about one 55-minute period. You may want to break it up into two half periods on different days. If you do this, have the students write-up their theories as homework between the two days. These written assignments can be posted for the class, and students will be able to examine other student's ideas. At this point, the concept of publishing and peer review can be discussed.
