Beats falling in line

What is our derivative today

A bluesy-chime?

.......

In this curve of time

We need a degree of differentiation

To establish our rate of change

With respect to time.

......

There are a number of ways

To fix this derivative:

In the end they all amount to the same

Number: 

..........

In the fourth dimension

The gradient of the curve of time

Is flat, time is still,

Unlike the curvature of spacetime

Where black holes appear

Or, so the Schwarzschild radius shows:

...........

Gravity is the mass of the object

Times the speed of light.

A singularity, a curvature,

Is made by a dark star out of sight.

.........

This child's fright

Is set in the deep-set night

So large that even

General relativity theory breaks down

As we just look around

And cry.
