Dear @Sonam, where is the dimension time? Maybe something more! 

http://science.nationalgeographic.com/science/space/universe/origins-universe-article/

Equivalently - where is the origin of a 2-D sphere surface ?

A bit of an odd question .....

Nice question Sonam Kumar

We may get some nice explanation for your question but not a definite answer.

Instead of thinking about very big Universe, we can start from ourselves.

Your question is equivalent to "Who am I?"

This body? This body is unable to tolerate even a small pain but get burned/buried after stopping breath. 

Oh - Heart is me!! No - While doing heart valve transplant surgery, your blood is circulated thro' Heart-Lung machine. Your heart was cut into few pieces and then stitched back together like football cover. 

May be breath is me - so where is it going after our death.  We all are breathing same oxygen - why so many differences in everything?

So if we find the answer for "Who/where am I located?" then it is easy to get the answer for your question. 

I agree with @Dr Murugesan Muthu that this is a good question, one with more than one possible answer.

The description of the world we live in as a "universe" is itself a question mark.   It has been pointed out that the traditional model of the world puts us in an island universe, where space is infinite but all matter is confined to a finite region.   A more recent view of our world is derived from a multiverse model.  

In view of the dramatic developemnts in geometry since the time of Euclid (e.g., hyperbolic geometry, Riemannian geometry, fractal geometry), it is also reasonable to view our world as some form of a parallel universe with other worlds evolving in parallel with our own world.   The question How large is space? is relevant in this discussion.   The chart in the attached image is from Tegmark

M. Tegmark, Parallel universes, University of Pennsylvania, 2003:

http://space.mit.edu/home/tegmark/multiverse.pdf

The chart suggests a parallel universe in a Level 1 cosmological concordance model with the assumption of infinite space and ergodic matter distribution.   The other extreme is known as level 4 model in which mathematical existence equals physical existence.    In a level 4 model, the Wheeler/Hawking question is asked: Why these equations, not others?

Observers living in parallel universes at level observe the exact same laws of physics that we do but different initial conditions that those conditions in our Hubble volume.   So, instead of asking, What is the origin of the universe, we might want to consider asking What is the origin of our universe amongst parallel universes?

Dear All,

As H. Chris Ransford expressed carefully and politely, it is not likely to get an original and specific answer.

There were some threads about the origin of the universe like, is there the origin at all, Universe came from nothing, universe as dimensionless point, initial singularity... I am bringing them here, as some threads are fine and have very good answers.

Scientists believe that --- our universe began with one enormous explosion of energy and light, which we now call the Big Bang.

Further, it was something outside of time, outside of space, and outside of matter that caused all of this to come into existence.

Dear all,

Theoretical structures base their foundations on axioms and cosmology or the study of the universe as a theory so far rests its foundation on big bang, thus the beginning of the universe. It is not definitive but always in progress and several new ideas and unanswered questions as to what existed before the big bang and what caused the big bang in the first place, why that instant time. The existence of multiplicity of universes and the infiniteness of the extent of universe.

Any thing that has infinite extent has no center, the number line has no center, we simply put an arbitrary point to represent zero and say to the right and left of this imaginary assumed point to be this and that. The same thing with an infinitely extended space, as any point of the space can be the center. You can make the spot of earth or that of the sun or of an another sun of another galaxy as the center of the universe as they all are equidistant from the boundary which is infinitely away. 

The study of cosmology is one of the challenging endeavors humans yet to work for so long to come up with a definitive answer as to where, how and why the universe begun.   

Dear Sonam, I want to think that you asked this question to intrigue the audience, since the concept of a Cartesian coordinate system is not the holly Graal...

The real question is if actually there exist an upper limit in the complexity of all possible local universes, see here:

Concepts like space or time origin are skeletons from old eras...

Article A new cosmological paradigm: universal locality

Dear Sonam,

• Now lets first come to the topic of co-ordinate geometry. You're a mathematician and you have far more deeper concept than me in this segment, so if you look into the very basic concept of using a co-ordinate system is to get a calculated and proper estimation(hold of the object) of the object that we are trying to define. And this being done by taking a point as the origin or what we call as the point (0,0,0). Now this whole concept is alive around the fact that this is taken as the reference to define the object exactly and all the calculations are made on the basis of that, which can be taken at any point from/on the given object.

            Now I've used an example given in the diagram below. The used black object                 be a sphere, now to determine the nature or dimension or to do the calculation                 I've have used two different ways of representation but if we do it we would find             that both the answers are same for the different ways of representation.(May be             a little difficult for the first or the latter). So what we can see that it doesn't matter             of what/where we take the (0,0,0) or the origin, as we eventually will reach the                 solution.

           So we can say that reference phasor doesn't affect the calculation and it can be            considered anywhere even at the core or the surface of the earth.

• Now lets come to the topic of the universe, as of the question it says that it provokes in the mind a depiction(which I would say rather illusion) of the universe/solar system in a 3-D plane or xyz-plane. Now the fact that we have read about it(The UNIVERSE), how it started with a boooom , the BIG BANG(which is obviously a hypothesis). Now let us consider it as TRUE for now. Lets proceed to the fact that it was something before the blast, now for what your post in RESEARCHGATE says that the schools with their curriculum taught us the universe to be a 3-Dimensional model. Now if this assumption is true as well then the minute/sec before the BIG-BANG it was a concentrated mass of 3D. After the BIG-BANG that 3D model been shattered in to pieces, so there was and outward thrust that take it all apart as we can see in any kind of explosion. Now this will result in the expansion of the universe if that BIG-BANG truly happened to be as it says. So this expansion would say that at a particular time say 't' sec the position of different objects that got scattered due to BIG-BANG would be different at a time 't+dt' (where dt is the small change or increment in time). So every time we measure the universe, it is not the same, it expands(or eventually it will contract after reaching a threshold). So time comes into consideration if we want to define universe with our current resources(or rules of science). So it(The Universe) being a 3D object got an influence of the time and it affects the calculations being a factor. So it should be taken into consideration and that may create and add the concept of one or more dimension into consideration. For getting a proper estimation of the universe we need to , for sure, change the current rules or theories or assumptions or statements that are followed in mathematics(Though I do not know the recent developments).

Now all this was according to my realization. So if any error in there please keep a note of it and ask, I'll try to explain in the best possible way I can.
