What's up?
He says to me
Oh, how I love queries like these
They seem to spread from mouth to mouth
Like a disease
Plain and simple
Concise.
Yet so fascinating to attempt to fully answer

"First the cieling
Then the sky:
The atmosphere of our planet,
Then space,
'The final frontier'
Extending outward, possibly to infinity,
Then perhaps the multiverse, if we are so lucky,
After that, who knows."

"But then again,
Up, down, left, and right
Don't really exist after all.
They are merely relative to where one stands on the Earth
All sense of direction melts away
Once you break through the atmosphere
But it may be difficult to tell where the atmosphere really ends
It's thick at the bottom, and slowly thins as you move outward
Until it is not there at all"

"But I'm probably wrong.
I'm probably wrong in every single way
Wrong in more ways than either of us
Could ever comprehend."

"We are so small.
Only human
But also so large"

It doesn't really matter though.
