So /sci/ I have a question. You got a Planet made of pure oxygen there is nothing I mean NOTHING on this planet except oxygen. The Atmosphere is 100% Oxygen, the Oceans are bodies of liquid oxygen. The Ocean floors and polar caps are solid oxygen. Now let's say some dumbass were to pull a lighter and try to light a cigar in this newfound fresh abundance of oxygen. What would happen? (Other than his Immediate death,) Would the entire planet explode?
