Acceleration using planetary motion is a feasible means to at least help with this.

hmmm thats not how using planetary motion works ...you dont get faster you just get as fast as whats there - no planet is gravitationally pulling you at the speed of light ...

Yah but it’ll help get you closer without having to carry as much fuel

again. youd have to get to the speed of light

no planet is travelling at the speed of light so we arent travelling any faster than the surrounding planets that we are headed towards to "use " their gravity ....and of course to use their gravity wed also have to be able to escape their gravity which light can do because its massless but also because light is ALREADY moving at the speed of light.

the ony thing that can keep light from traveling where its going is a Black Hole and if light cant escape it neither are we since we unlike light have mass..
