The black goo does one simple thing
by brightgeist
It directs (and accelerates) mutations towards a specific "goal". and, obviously, the goo in the first scene of the film is NOT the same goo that causes all the problems later in the film. the difference between the 2 goos are their "goals".
the engineers seem to have the ability to do genetic programming on a deeper level than simple DNA. yes, they use DNA obviously, but apparently they can set a "goal" to their mutations.
so, when they "create" life on a planet, they use their own DNA as a basis and start the evolution that will, after billions of years, reach its "goal" of human beings.
the weaponized goo, on the other hand, has a very different "goal", and a highly accelerated mutation rate. the "goal" of that goo, as we can see in the painting on the wall of the Big Head Room, is the "xenomorph", although obviously a slightly different model than the one from ALIEN. and whatever DNA that goo touches, it starts aggressive mutations in the direction of that xenomorph form.
of course, when that goo gets in contact with a grown human, it doesn't "transform" him into a xenomorph, because that's not how evolution works. it simply creates mutations in him, as we see in the cases of Fifield and Holloway.
but when the mutated DNA is transferred into a new cell through reproduction (as happened with the worms, apparently, and with Holloway and Shaw having sex, and later with the impregnated engineer), a newly evolved species can grow.
so i think this really explains the goo in a consistent way![]()
The Black Goo can be Engineered to be used either as a Positive Life Force or Bio Weapon
by fitz-hume
On Earth the Engineers used the Black Goo to advance life, to kick start the evolution of the species, us included, by mixing it with their own DNA.
The Black Goo found on the Engineers ship was engineered to function as a bio weapon. In this form the Black Goo causes wild destructive mutations that turn what ever life form it mixes with into highly lethal murderous beings. Humans turn into sick mad murderous beings programmed to wipe each other extinct. Mixed with worms and a sperm cell it turned them into freak versions of facehuggers, beings that live to pregnate other living beings with their destructive bad seed. The biggest creature that was born from a mutated human sperm cell was basically a huge variation of a facehugger and functioned in the same manner. It pregnated the only living Engineer and alas a big xenomorph baby came through his chest, one that was quite clearly a Queen Alien baby.
Like Lindelof himself said the question to ask after seeing Prometheus is "What does the black goo do?".
