There are non-rocket ways to space, like a catapult or maglev accelerator. Or ways to assist the rocket outside the rocket equation, like a spaceplane launch platform. Or even Project Orion nuclear explosion propulsion. (Which is subject to the rocket equation, but with nuclear rather than chemical fuel for a much higher multiplier of energy per mass.)
