# Always day and always night - a riddle

Can anyone solve this riddle?

Always day and always night,
You'll know me when you see the light.
But don't look up, don't mess around -
In these words is where I may be found.
Through eternity ever I flowed,
Beyond the marble you call your abode.
I am warm and I am cold;
Visit me if you are bold.
If you are confused sometimes,
Just relax, read between the lines.

Space.

Always day and always night,

Day and night are properties of planets with a sun, but space contains all of these planets, including both the parts in day and the parts in night.

You'll know me when you see the light.

We [mostly] see light through empty space.

But don't look up, don't mess around -

Ceilings and the light sky by day obscure our view of space.

In these words is where I may be found.

Spaces between these words.

Through eternity ever I flowed,

Space has [probably] existed as long as time has.

Beyond the marble you call your abode.

Space surrounds the Earth (the marble) that's our home.

I am warm and I am cold;

Space has no temperature, but places in space will be very hot and very cold.

Visit me if you are bold.

Brave the final frontier.

If you are confused sometimes,

Spaced out.

Just relax, read between the lines.

Spaces between the lines.

It is in the source code :-)

Edit:
@downvoters, the question was/is if anyone can solve this and there were/are no other restrictions. So i choosed the easiest way for me [looking up the source code].

Edit 2:

• where in the source code?! – d'alar'cop Aug 24 '15 at 13:49
• Who cares if it's in the source code? This is so howlingly obviously contrary to the spirit of a riddle. – dennisdeems Aug 24 '15 at 14:59
• I care! This is my way to solve a riddle, looking up the code understand the way it is handled etc. Kind of a riddle by itself. I don't think there is the one and only right way to solve a riddle, especially when there are no restrictions by the OP. – Wa Kai Aug 24 '15 at 15:07
• Looks like legitimate lateral-thinking to me. The question didn't say no computers. – A E Aug 24 '15 at 19:38
