What is Depth?

It was not too long ago
that we made a
startling discovery

For a very long depth,
we knew nothing of it.
depth was apparent,
but unknown.

What is this
Mysterious scale,
Apparent for an instant,
But gone in a meter?

People were distraught
For a very long depth.

Naturally, there were
Those who denied
The concept of depth.

But then, there were
Those who said that
Our world was in
The present.

We know better now.
After a suitable
Span of depth,
We know better.

They ask,
"Is depth real?"
They say,
"Depth is an illusion."

"My eyes,"
They postulate,
"Can see the run and
the rise."

"My eyes,"
They insist,
"Can see aeons
inside."

But how they do stumble,
When considering depth!
Oh what a madman I must be,
But I truly believe!

And they say, "Preposterous!
You mean to propose
Some sort of unity,
Some kind of duality,
Some manner of marriage
Between width, height,
Time, and depth?"

And though I am skilled
In Linear Algebra,
And I am
A Theoretical Physicist

They stare at me in wonder,
And query me for drug use

Thus, they begin to wonder,
"Is depth travel possible?
Can I travel upon any point
In depth?"

We will find the answer,
And quite literally,
Go 30 meters
Towards the back
