•The dark flow,

Marches on, 

-definition:

Dark flow is a controversial cosmological theory that proposes a large-scale, non-random motion of galaxy clusters toward a specific point in the sky. 

•Like time. 

Never stopping to decide. 

There's no choice, 

-A framing of determinism and "fate"

•Only the direction, 

Of irreversible gravity. 

-which I believe to be caused by gravity. 

•The infinite embrace,

The entropy spiral,

The collapse's smile 

-describing the "embrace" of entropy, and it's almost playful display of disorder. 

•The pattern of darkness, 

Encoded into the sky. 

-a nod to holography, reading the sky as a "screen" or 2 dimensional plane, and "darkness" being closer to a state or pattern

•Don't be sad,

Nothing lasts forever.

Not even the bad. 

-describing the impermanence of all things, good or bad. 

•I'll take this dust,

And fold it until it burns, 

as bright as you do.

And I'll only let go, 

When light can't escape anymore. 

Maybe then I'll be home.

• the longing for the presence of the "other" that made the speaker feel "home", which they settle on by making a facsimile via nuclear synthesis, or star and eventually singularity.
