Julian: Oh, boy. This poem is titled "An Ode to Telescopes: A Completely Original Poem" by Julian Huguet." Okay.
Twinkle twinkle, little star
how I wonder what you are?
Why some wander in the firmament,
while all the rest are permanent,
and how it is that each of you seem equally afar,
as much as I squint and strain
points of light you all remain with lenses ground for eyeglasses ,
the new use for the spyglasses
to maximize your tiny size and minimize my pain.
Who'd have thought it would disprove
the claims of many men who have
working under an assumption said
the shy's implicit functions
place Terra firmly in the center
and yet it moves
tones of new techniques evolved,
lenses limits were resolved
now Spectra are divisible
and specters once invisible
shift the size of star-filled skies
still riddles are unsolved
first stories remain untold
so I'll venture to the cold
I'll ride fires of discovery
roam and search the skies above me
pull out the pins and soak it in
the universe unfolds
I've gazed on Luna's lovely face
Gained perspective on the human race
set off on a frontier chase
and found my place in time and space.
I see the stars now sprinkled
through the fabric that they've wrinkled
and cannot help but be amazed it started with a twinkle.
Hank: Woooow
Sam: Bro, come on,
Hank: give me that line again, I see, I see with the fabric that they wrinkle thats what was that give me that again
Julian: I see the stars now sprinled though the fabric that they've wrinkled
Hank: through the fabric that they've wrinkled, damn boy
Julian: Yeah, if there's any Grammy competitions, like tickets for peotry slams, I'm also in it to win it too
Hank: So the topic for today is telescopes which are, i think we know what those are, right Ceri? I guess they're just things you build to make thinks look closer than they are.
Ceri: Yeah, you, observing distant, distant objects
