WHAT IS 4th DIMENSION ? | WHAT IS TESSERACT ?

BY: Arjit Mishra

DIMENSION: A measurable extent of particular kind such as length, breadth, height. 

4th Dimension is basically a mathematical extension of the concept of 3rd Dimension.

FACT : The idea of adding a fourth Dimension began with Jean le rond d'alembert with his "Dimensions" Published in 1754.

Firstly we should go through 0th, 1st, 2nd and 3rd dimension :

0th dimension : In 0th dimensional  world there is no measurable extent, more specifically in this dimensional world object sticks to it's position like a point.

1st dimension : In 1st dimensional world there is existence of only one measurable extent, object would move only in a line.

2nd dimension : In 2nd dimensional world there are two measurable extents, length and breadth.

3rd dimension : In 3rd dimensional world  there are three measurable extents; length,breadth and height.

NOTE : From above explanation an observation can be made that "Every dimension is made with the help of it's preceding dimension."

4th DIMENSION :

Now 4th dimension must have be made with the help of it's preceding one whiz, 3-d .

This is the image of 4th Dimension from our 3-D perspective

Scientists on the basis of theoretical consideration made Time as the 4th Dimension.

The reason behind this is all the living things lives with time and become older with time.

hence time can be considered as a major element which effect every entity in the space.

This relation between Time and Space results into 4-Dimensional space-time.

NOTE : Space and Time coexist or they don't exist independently.

This is how you can Imagine a basic or Ground structure of a 4-dimensional object :

Above figure shows the basic structure of 4-d object(commonly known as tesseract). As shown it's structure changes every single moment.

Human life in 4-D :

Through this image we can conclude that with the help of 4th dimension we can physically interact with our every phase of life. 

But unfortunately humans are not made to observe and interact with 4th Dimension.

We Humans are 3 dimensional entities or more specifically in philosophical terms we are slave of time; we live in present and cannot go physical with our past and future.

Now a question must be arising in your mind that can we do time travel with the help of Dimensional Analysis?

The answer of this question is yes.According to the super string theory there are at least 10 Dimensions in the observable Universe and if somehow we can trigger 4th Dimension into 5th Dimension we would be able to time travel and this concept defies most of the time paradoxes.

"Time is our God and we don't exist without it"
