Astonomy and Cosmology Unit Final

Many things are happening in our universe. It makes you feel more optimistic that someday humans have the opportunity to observe all of them with their own eyes. Everything we learned about the universe in the past few weeks can be regarded as general knowledge about this subject and can be told at the party to impress everyone in the room Includes things. Most people experienced their lives without trying to understand the universe there.

Then I have a very specific question about cosmology. The standard cosmology, or what was considered a standard cosmology 20 years ago, the universe we saw around began with the big bang, in other words, it is a very hot, very dark state. Given the characteristics of this state, in order to explain the evolution of the universe, its state must be in a very low entropy state, in some sense very low entropy is unlikely to be very likely . Advancing this line will say, "Well, you tell me that the universe is in an extremely impossible state or is impossible." I would like to know if there is an explanation. Is there a principle that can be used to explain the big bang?

Entropy in thermodynamics, entropy in information theory, entropy in cosmology and entropy in statistical mechanics. Entropy (from 'order' of Greek entropy) was invented by German physicist Rudolf Clausius in 1865 to measure the level of disorder in the system. Clausius refers to the thermodynamic system, but since then this term has been widespread to explain random changes in every system. Example: You have a small business or a lean startup and want to increase your income by 50% in the second year of operation. You plan and make predictions and try to adopt an aggressive strategy to achieve your goals. Because of their ambitions and unrealistic expectations for their ideas, they often miss their goals and eventually lose hope and frustration
