Does the candle burn more or less violently in zero gravity?

more violently
about the same
less violently
nobody knows
In zero gravity, no convection occurs, that normally shapes the flame, disperses CO2 and brings fresh air to the wick. Without convection, CO2 from combustion does not disperse as readily and tends to smother the flame
