The trouble with vacuum chambers is they are nothing like space - they have walls , and therefore provide external resistance to propel from . Space
desn't have any walls , and therefore no resistance to push away from .
So when a rocket blast hits Cape Canaveral soil , it's pushing up from the ground, and as it continues up its pushing upwards from the accumulation
of pressurized exhaust against the air underneath it . It rises slowly at first and gradually increases in speed as momentum upward is gained . Huge
amounts of highly combustible fuel is needed to achieve this effect
In space itself , there is nothing behind the rocket from which to propel against. Exhaust pressure cannot accumulate but it dissipates into the
vacuum conditions and therefore no momentum can be gained . A similar effect would be like that of a punting stick , when pushed against the river
bottom , thrust is achieved effectively , but , when pushed against only the water itself , no thrust occurs , and there will be no forward momentum
of the craft .
