Space-Time Continuum - The fabric of Reality

I was thinking of a rhyme
To describe the idea of Space-Time.
If you follow Einstein's General Relativity,
You must know it's a unique, inseparable entity.
In fact, it's a curvature with four dimensions
Which is the greatest of all creations.
Here, Gravity is an outcome of its geometry,
And Time represents the causality.
We also call it the cosmos or universe,
We are moving (forward) across its vast expanse.
It is expanding itself towards the infinity,
With all its glory & beauty for eternity.
