Lets assume that everything I list below is possible (because some will be based on unknown energies). I have provided some links.
Take into account when choosing the drive
1.) How much it would cost to build?
2.) How efficient and easy to maintain is it?
3.) How fast it can go?
4.) Anything else that can go wrong.
Here are the options
1.) Antimatter rocket
2,) Ion drive
3) Bussard ramjet
4.) Dipole drive https://www.nextbigfuture.com/2018/...ss-space-propulsion-concept-dipole-drive.html
5.) Fusion rocket
6.) Halo drive https://arxiv.org/abs/1903.03423
7.) Solar sail
8.) EMdrive https://en.wikipedia.org/wiki/RF_resonant_cavity_thruster
9.) Photon rocket
10.) Magnetic sail
11.) Vacuum energy sail
12.) Nano electrokinetic thruster https://en.wikipedia.org/wiki/Nano_electrokinetic_thruster
13.) Quantum vacuum thruster https://en.wikipedia.org/wiki/Quantum_vacuum_thruster
14.) Plasma drive
15.) Beam powered propulsion https://en.wikipedia.org/wiki/Beam-powered_propulsion
16.) Nuclear photonic rocket https://en.wikipedia.org/wiki/Nuclear_photonic_rocket
17.) Pulse detonation engine https://en.wikipedia.org/wiki/Pulse_detonation_engine
18.) Mach Effect Drive https://en.wikipedia.org/wiki/Mach_effect
19.) Unruh radiation propulsion drive https://www.vice.com/en_us/article/...theory-of-physics-many-think-is-pseudoscience
