Questions challenging the roots of math and science

Yesterday (At around same time), I encountered with several questions (Maybe popular too) that challenges the logic's of math and science. As a analyst, I tried to figure out the answer of this questions. Unfortunately, Suffered from headache after brainstorming of 2 hours. Well, I am not an expert in scope of this questions but exploring the subject from last several years independently.

Here are the questions (Using simplest language to explain).

1) If you see in any direction in space at night. What would be the end of line in that direction?

There should be an ending point, right? Don't you think so. If there is no end, the next question would be "How the universe exists?" because existence can't be from nothing. If there is "Nothing", There is no possibility of anything.

2) Take a object, magnify it to maximum possible. Is there any stop of it? 

Where does the exact zero situated. Do you think that there would be any exact zero which would not be magnified further. Exact zero would be nothing and again, if there is nothing,  there is no possibility of anything.

3) Assume that you are in space. We have already discovered it, So, This assumption can be considered real. The question is, In how many axis/directions you can see? Is there limitation on number of axis?

In all of the above three questions, The main reason of our confusion is numbering system of maths. In more scientific terminology, The virtual visualization created by this system in our minds is the actual cause of this problems/confusions. The math is challenging our very own existence.

The fourth and final question that I came up with is.

4) We all are real for sure (As you all can think about yourself) because if this is false, I would not be writing this article and you would not be reading this. So, The question arises is "How the very existence of universe came into place?". 

Suppose, If there are unknown factors behind creation of universes, How those factors come into place from nothing?. Nothingness is opposing the existence but we do exist. So, The opposite is unimaginable.

I still believe that we will able to find answers of this questions. This could be done via Re-working or Re-inventing the Logic's of math and science which affects our perception directly or indirectly. I am just little doubtful about very existence of this questions at that time.

Have a great night, Its 2301 hrs IST here currently.
