spasmodic liquid metal and the thick black goo

A thick black goo spreads across all the universe, infiltrating the furthest reaches of conscious thought - whilst, slowing down all electrical activity, powering down all substations, and muting all vibrations to mere frozen shadows. But it ain't so bad - as long as you don't try and resist it that is. Meanwhile, travelling through space at speeds unknown to mankind; a super-thin, sharp, metal object is violently wobbling and slicing its way through the universe  - fighting for space against all other matter that ever was or could be. Sometimes I feel like reaching into my head, puling this spasmodic silvery thing out, and asking what the deal is? - but how could I seriously contemplate such a thing without first understanding it's contours, smell, and origin?
