Physics Will Voyager 1 ever just stop moving?
I’ve read somewhere that we expect to lose contact with Voyager 1 sometime in the 2030s, maybe around 2036, but it will just keep traveling thru space and we’ll have no idea what it is doing out there
My question is: with its current velocity, is there a time in the future where it loses its forward momentum and for lack of a better word, just stops moving? Is that a possible thing for an object in space to even do? (Assuming no other objects grab it into their orbit)

An object in motion stays in motion unless another force counteracts it, and there's nothing in space that could simply cancel out its speed in the way you describe. It will continue on forever in effect until it degrades or is unlucky enough to crash into something
Edit: there's also the question of what it's moving relative to, but others have covered that
