would solid fuel rockets work in a vacuum? according to newtons 3 rd law for every action there is an equal and opposite reaction, when the hypothesis that they do not work in a vacuum was "disproved" on mythbusters they vacuumed out a chamber put a small solid fuel rocket motor on a toy car and the thing took off after a brief delay, my contention is that was only a vacuum briefly before it was a gaseous enviro from the burnt rocket gases allowing the ejected gas to react with the newly created environmental gas, in the vacuum of space there would be no resistance to the expelled gas therefore is it possible for rocket motors to produce thrust in a true continuous vacuum such as space?
^thats always confused me, there is nothing to create resistance for the rocket to propell...I would think as shit is being shot out the rocket it would just keep going and the rocket not move, unless you need a certain amount of power to creat a little area behind the rocket for it to be able to have enough resistance to move...that prolly dosent make sense I'm having trouble putting what I'm thinking into words
