the gentle push that moves a rocket through nothing toward everything.
means A device that produces thrust to propel or steer something — a spacecraft, boat, or submarine — by expelling mass or fluid in the opposite direction.
from From 'thrust,' a Middle English verb (thrusten, thrysten) borrowed from Old Norse þrýsta, 'to press or force,' plus the agent suffix '-er' that turns a doer into a thing that does. So a thruster is, quite literally, 'the thing that pushes' — the word kept its plain Norse muscle even as the machines it named grew sleek enough for vacuum.
