There's a lot of potential applications for mass manipulation, if it's possible. You'll be hard pressed to find specific examples, because a lot of them depend on how mass manipulation would be possible.
Potential applications could be in energy generation or the creation of ultra light materials, which could open the doors for affordable space travel (or just better more fuel efficient travel here on earth). Understanding how mass works is one of the final puzzle pieces in physics, and could lead to countless breakthroughs in a number of areas. It's not a trivial theoretical pursuit.
