Boundary of an universe - what if it is there ?

Hello Reader, thanks for stopping by, and welcome to my blog.

  Disclaimer: The below article is the summation of the thought process I had during my schooling age. I just conveyed what I was thinking about the universe. Please share what you think about my idea in the comments section :)

 The below article is a collection of my ideas & views about Space/Universe.
 I discussed these things when I was actually preparing for an exam (I like to spend more time like this rather than preparing for the exam :))

Okay, It was all started from here ..... when I was reading my textbooks,  suddenly I had this thought -  we know our universe is very large, what if it would happen or look like when it has a boundary?

Oh is it ?...

but I told myself...

but we already know, Universe is very vast and it doesn't have any limits as the main components of a universe are Time and Space, which are continuous in nature, and how it can have boundaries?

And again I told myself, Okay let's consider a simple example...

      Normally, everything occurs based on some event that triggered it, like - we feel hungry because our body needs energy  & Trees bloom flowers to bear fruits and likewise...

 " A man feels cold because it is a winter season.  It is winter because due to the position of the Sun and the Earth.  The sun and the earth are placed because of an event that occurred in the universe (Big Bang)"
  

      If we closely look into each and every causal happenings, it eventually ends up with a question, what is the event which resulted in the formation of the Universe?

   [ literally, I was laughing here ... why I posted this blog and why my mind was thinking in a crazy way]

Let's group a few things together, 

I myself thought about few contradictions and mentioned them below,

Case 1

                     The universe is eternal, which means it has no event which triggered the formation of the Universe and because it never began from any source/point. But we cannot tell this is correct as there are many observations and findings shared by many great scientists, which proves Universe was created from some source.

There is very good evidence that the universe

is around 13.7 billion years old and has evolved since its creation according to the big bang theory.  

Second, there is a law of physics called the second law of thermodynamics, or the law of entropy.  This says,

 The amount of disorder in the universe is always increasing and can never decrease. 

 If this law breaks, many other laws, such as conservation of energy and the direction of time, will also break.  

Therefore, the entropy "clock" must have started at some point in the distant past, when the laws of physics were created. Can we consider this as the beginning of the universe?

Case 2

                    There is an endless cycle of universe creation.  This is the big bang or big crunch model or the baby universe model.  The actual point is that our universe was created by another universe.

This may be possible, as stated by the physicists. However, it does not address our question, from where and how did the first universe born?
