I suppose a fire expands as a sphere until the fuel runs out, or becomes so thinly dispersed that it is below the combustible concentration, or cools because of the increased surface area of the sphere. A fire fed by a spewing fuel source, such as the Mir disaster, could concievably fill the entire capsule - yikes. The American who was on the capsule at the time said the fire was intense near the outer wall, a thin layer of aluminum alloy between life and death. Sailors on wooden ships used to be afraid of shipboard fires more than anything else. I'd assume astronauts would have the same qualms. --Lawrence Lile ----- Original Message ----- From: "rad0" To: "Lawrence Lile" Sent: Tuesday, September 04, 2001 4:12 PM Subject: Re: Re: [OT]: Moon landings hoaxes ? > this is really pretty interesting.... > > what does a gas do in space? does it fill the volume > containing it, same as here on terra firma? > > and if it does, why doesn't the fire, or reaction, climb outward > on the gas? this would make a fire appear as an outwardly > growing ring, or I guess sphere... > yikes... > > > ----- Original Message ----- > From: "Lawrence Lile" > To: > Sent: Tuesday, September 04, 2001 3:53 PM > Subject: Re: [OT]: Moon landings hoaxes ? > > > > Fire in space (Zero G atmopshere) is actually very wierd.
