I know that chemical rockets would allow for some minor loads to escape the gravity of a planet with higher gravity.

My question is, what kind of technology would possibly allow a dominant species to escape the gravity of a planet and become a somewhat spacefaring species?

Are there any possibilities in today's technology, or what fictional technology might accomplish this that might be in our near future?

In theory Space Elevators are possible regardless of the surface gravity of the world on which they are built, material tensile strength is an as yet unsolved issue with building these structures. Wil McCarthy's Hacking Matter proposes some options in this area but the practical applications are still some years away.

Alternatively any form of em drive, field propulsion system or gravimetric drive, would work but none of these systems is more than highly theoretical at this time.

That's all if you want rocket-like spaceships whizzing about; if all you care about is spreading a species to the stars then the Einstein–Rosen bridge is also an option. Wormholes allow you to send people to other worlds with or without spacecraft and with any technological or magical embellishments you want to use.

Maybe your planet has some very high mountains - maybe one of them is that ancient chondritic meteorite? Or you can use rockoons. Capitalize on buoyancy to lift your spacecraft high above the ground. You can only get to about 100,000 feet on earth because the atmosphere thins out, but the amount of atmosphere a planet has does not depend on its size. You can give your heavy world an atmosphere way out, enabling a balloon to rise considerably farther before releasing its rocket cargo.

If rockoons bore you, maybe a rockeloonannon. Yes, there is a cannon involved. Usually that improves science.

If rockoons bore you, maybe a rockeloonannon. Yes, there is a cannon involved. Usually that improves science.
