Is a light source really casting its own shadow?

Only light giving to outside sources, 

It can’t illuminate itself

Leaving everything around in the dark

Illuminated and illuminator 

Of only the non-emiting matter

That give off no light.

Does the light know what illumination is?

Or does due to the sources nature, exist in the dark?

For Only when something brighter

Comes around or is strong enough to

Over power the original light sources

Light enough to cast a shadow, 

To Shine a light 

Through to the other sources light emitting source

Does the light source Know what light is

By finally being cast into another’s shadow

As opposed to being the sole

caster of shadows

Would a light ever desire (hypothetically)

Then if all the light source experiences is shadow

To find another light source

Just to be able to be 

With light

And not darkness.

A black hole

Caster of illumination, and light?

To the singularity, everything 

Is bright, illuminated, light

The only shadow or darkness is the singularity

The shadow is the singularities energy, 

Where That ends all is light

Of course the black hole, can’t observe itself or inside itself

So the singularity has no

Idea of what shadow, or darkness is.

only that everything around it is bright and illuminated

Only against another black hole, 

Of same or greater magnitude 

Would be able to make

The singularity

Be able to appear brighter

Then the other.

So would a black hole

Desire to be devoured by 

Or to orbit another singularity

Just to have a shadow/ darkness near?

To know what darkness 

What itself is?

Just to be able to look

Into another pupil
