> SO WHAT DO THE ROCKET ENGINES  PUSH AGAINST?
> HOW DO THEY WORK?

I haven't follwed the thread too closely but

"For every action there's an equal and opposite reaction". In a
location with no atmosphere (eg a Yanni concert, jk) the rocket
is as much moving away from the exhaust as the exhaust is
moving away from the rocket, like a continuous recoil. Momentum
either side of the exhaust nozzle is equal
