A self-replicating nanotechnology designed to clean up pollution has gone haywire and is now converting all matter into a grey goo-like substance.
Develop a counter-nanotechnology that can neutralize the rogue replicators or reprogram them to a harmless state. Utilize electromagnetic pulses or chemical agents to disrupt their function.
Analyze the replicators' structure and behavior- seeking to understand their weaknesses and vulnerabilities. Use computer simulations to model their spread and predict their effects.
Establish containment zones- using physical barriers or energy fields to prevent the spread of the goo. Evacuate unaffected populations to safe locations.
Deploy a large-scale incineration system to destroy the goo- utilizing high-energy lasers- plasma torches- or nuclear explosions- if all other methods fail and at great cost to the local environment.
If possible create a space-based mirror array to focus solar energy and vaporize large areas of goo in a controlled manner- hoping to starve the remaining nanites of material.
Grey tide consuming-All forms dissolve to inert mass-Sunlight our last hope.
