as someone already pointed out, the problem with traveling through space without fuel is that eventually you will get pulled into something's (a star, planet, etc) gravity and crash into it
the brown dwarf theory i referred to earlier is a theory that our sun has a twin star that is a brown dwarf. it is very small and dense and has a very irregular and long orbit through the solar system. in the theory it is speculated that our asteroid belt was once a planet that got too close to the brown dwarf and was ripped apart by its gravity. another theory that goes along with this theory is that pluto was once a moon of neptune that got pulled away by the brown dwarf into its own weird orbit.
scientists speculate that the reason we havent been able to actually detect the star is that its currently out past pluto somewhere and i guess brown dwarfs are hard to detect since they are small and dont give off a whole lot of energy
i heard this theory about like 7 years ago, so it may have already been disproved. but nonetheless, i personally find it very interesting
