What key scientific advantage is gained by observing fire behavior when buoyancy is removed in space?

Answer

Isolating the effects of diffusion and chemical kinetics from gravity

Studying flames without buoyancy allows scientists to gain cleaner data by isolating the fundamental processes of diffusion and chemical kinetics from the complicating factor of gravity.
