What does a rocket push against in space?

Apart from the ascent module launches from the lunar surface and every shot of a reaction control thruster that adjusts a trajectory and de-orbit burns you mean?

"Houston here, you are go for your engine burn, make sure you film it to keep the fruit-loops happy..."

The flat earthers definitely won't be happy even if you film it, they just flatly declare everything about space flight is faked, so there's not much point in filming it, though there are videos of the lunar ascent module taking off in a vacuum.

the ascent module launches

Yes they have their own conspiracy theories because you can't see the flame, but the moon hoax theorists don't really seem to care about details about why that is so, they just claim it proves it's a fake:

How the Lunar Module Launched from the Moon Without a Flame

Would a boiler blow up in space if you heated it ? If it would, then imagine the V shape of the rocket nozzle exhaust with tremendous expansion pushing against the inside of the V nozzle. Would be the same as the particles of the boiler expanding after the explosion.

Inertia.

It's a powerful force.

50 years and still only vids of rocket launch (all the way) INTO space but none of rocket propulsion IN space.

Here's one. In the video below, every time the Apollo LM begins rolling and stops rolling, it was due to a rocket thruster being fired in space, in this case of 16 (four sets of four) Reaction Control System, or RCS, thrusters. The RCS thruster engines on the LM used hypergolic fuel (Aerozine 50 fuel with a nitrogen tetroxide oxidizer) which burns virtually invisible.



Here's another. The space shuttle also had RCS thrusters In the video below of a shuttle preforming the "flip maneuver", the shuttles RCS thrusters need to activate for a short time for the shuttle to begin its flip, then activate again to make the shuttle stop flipping:


The shuttle RCS engines burned monomethylhydrazine as fuel and was oxidized with dinitrogen tetroxide. This hypergolic fuel combination also burns invisible. The RCS engines on the shuttle are the round holes visible at on the top and sides of the nose, and other small holes near the aft section, some of them visible in this video as a line of three circles on each outboard side of the main engine assembly.


If rockets didn't work in space, then the roll and flip maneuvers of the spacecraft shown in these two videos would not be possible.
