I picked one stanza out of this to critique. I generally like your imagery, the lack of syntax makes it hard for me to establish a true sense of rhythm.
we all know in spaceno one can hear you scream - telling people something you assume everyone knows is generally a bad idea in writing.
Try this on your eyes:
"to plunge through those hidden
stars, choke on brine
let it strip my lungs raw let
bubbles stream in oil black slick and
sink, and sink
and sink and
sink
sink"
The image, the way you word this, is to suggest you are frightened. This is the meat of that stanza, this is where it's at, that human element.
