"I" in your Header !!??
Stanzas 2-4 are very nice, they make a total poem. Stanza 1 should be removed, it spoils the poem, it is a bad eyesore, with its unnecessary political and scientific jargon plus semi-joking and semi cliched "heart". No need for all these.
You may still do something about line "And what else there’s to reach". It has no content, be it in general or poetically (I hope you are not counting on any graphic interpretation of phrase "to reach", it would cheapen your poem).
PS. I don't understand the other comment when it talks about "a" and "I".
