This research pertains only to the question of how we propel an object in a way that enables interstellar travel with a duration of fewer than ~100 years. There's a whole other question, which must be answered separately, about how to keep that object from being destroyed during its travels. The effectively 2D graphene material might be the right material from a propulsion perspective, but it may be totally unsuitable in terms of making sure the object gets to another star system in one piece.
