If fire needs oxygen to survive, does this mean you wouldn't be able to start a fire in space?

    That's essentially correct, although there are other elements and compounds that can act like oxygen to 'burn' something...

    • aluminum nitrate. ammonium persulfate. barium peroxide. hydrogen peroxide solutions, magnesium nitrate. nitric acid...

    Unless you had a source of oxygen, correct.

    Fire needs fuel, an ignition source, and an oxidizing agent.

    Unless you provide the oxygen, yes.

    Obviously yes.  Unless you take some oxygen with you, as you do on a spaceship or space station so the astronauts can breathe.

    If you're thinking of stars, they aren't burning in the normal sense, they're shining by nuclear fusion.  A star starts when enough gas comes together that its own gravity compresses it, it gets hot, and that's hot and pressured enough for fusion reactions to start.  These release energy, you get light and heat, but no actual flames.

    Correct, unless you bring oxygen into space, or another oxydizer.

    Correct. Fire can not exist in space or in any atmosphere without oxygen.

    The answer to your question, is 'no' 

    and newly-formed stars prove that fires can start in space. 

    Remember ... It doesn't always take oxygen 

    and rubbing 2-sticks together to start a fire. 

    The chemistry of the Universe contains many secrets.

      Stars are not on fire.  They are undergoing nuclear fusion.

    yes. that's exactly what it means.

    depends on what you mean by "in space". On the space station, there is plenty of oxygen and fires are very possible. In a vacuum, no, you cannot have a fire. On a planet with oxygen or some other oxidizer atmosphere, yes,
