What would Fire look like in Zero Gravity?

Question

I was thinking, since Fire cannot burn without oxygen, how would it look if it was in zero gravity, since there would be no oxygen?

Answer 1

Zero gravity does not necessarily mean that there is no oxygen.

For example, rockets take oxygen in tanks so they could burn the fuel in outer space.

Answer 2

like a orb round almost like a little sun

in zero oxygen it would not burn

is this some kinda trick question

Answer 3

To burn, fire needs a flow of air.  This is normally caused by convection.  However, in zero g, it is tough for the fire to get new O2, i.e., air.  Here is a video of a candle burning in space:  http://www.youtube.com/watch?v=xJhxEqCds...

If you were outside, you can always supply both oxygen and the material to be burnt as in a rocket engine.  You can also have solid rocket fuel which burns without air (there is an oxygenating agent in the solid fuel).
