Alright, ERA. Hear me out...
This is not a particularly great film, but the central McGuffin is germane to the discussion of cosmic horror of a bizarre, unknown nature.
It's this big, pink glowing thing that according to the movie's supercomputer contains "9th dimensional matter" which is about as fucking weird as it sounds. Aside from altering and enhancing the genetic structure of organisms that even hang around it and it's strange telepathic aura, the film's conclusion suggests it also has the power to collapse the universe and/or spontaneously evolve all sentient life if it's, um, turned on by going supernova.
There's lots of vague speculation on the creators of this artifact, but since the humans in this film have never made a First Contact yet, it's not out of bounds to consider that this could be something crafted by the Great Old Ones. They openly wonder if it's a weapon, or maybe even just a toy, but the longer they hang around it, the more chaos and destruction it wreaks.
Like I said, kind of dopey movie, but it's got a cool cast headlined by James Spader and Angela Bassett. Check it out, OP.
