A few years ago I wrote a poem titled “A cosmologist worries (about infinity)” inspired by a conversation with my friend and cosmologist, Tanmay Vachaspati. I remembered this poem recently when I was playing with Suno the generative AI song generator. So I wondered what AI would come up with if given some similar themes to play with. So I gave it the following prompt:

Prompt: A beautiful melodic acoustic song about confronting the thrilling yet scary idea of living in an infinite universe where everything heart-achingly beautiful and horribly terrible can coexist.

This is in keeping with some of my experiments with AI and creativity (a more complete list can be found here). It came up with a set of lyrics and two different versions of the song – along with some cover art!

Endless Sky (version 1)

Endless Sky (version 2)

What do you think? I am utterly musically untalented so I am easily impressed. I am better with words, and found the lyrics pretty good, honestly. These two lines in particular really stood out to me.

In the vast cosmos we play our part
Bound by the fabric of time and heart

Here are the complete lyrics

Endless Sky

[Verse]
Under the endless sky we stand still
Heartbeats race eyes wide feel the thrill
Infinite stars above whispers they hold
Stories of beauty and tales so bold

[Verse 2]
Everywhere we turn light and dark
Both paths we tread leave a mark
Fear and wonder hand in hand
In this universe where we stand

[Chorus]
Thrilling yet scary feels like a dream
Endless the universe more than it seems
Beautiful heartache terrible bliss
Night and day together in a kiss

[Verse 3]
Galaxies spinning worlds far away
Moments of magic shadows of gray
In the vast cosmos we play our part
Bound by the fabric of time and heart

[Bridge]
Out in the unknown we search for more
Facing the beauty and all we abhor
Everywhere chaos and wonder reside
In an infinite space where worlds collide

[Chorus]
Thrilling yet scary feels like a dream
Endless the universe more than it seems
Beautiful heartache terrible bliss
Night and day together in a kiss
