And probably an even bigger deal if they aren't found.

For one, gravity waves are a definite prediction of Einstein's General
Realativity. At some point, the sensitivity of gravity wave detectors
will be such that if they don't turn up, it will be a mjor
embarrassment for GR.
Then, if they do turn up, we can start to use it as another window on
the universe. For example, gravity wave detectors will be just the
pants to peer inside collisions of massive bodies such as neutron
stars and black holes. Also, it might give us good intelligence as to what's
going on in our galactic centre.
So yeah, if found, it'll be quite a big deal.

What difference does it make (to us) if something happens 50 or 650 million

Iwould be less benevolent and call those "rumors' rather fantasy (even if
supported by some human mathemaital considerations...)

On Thursday at 10.30 EST (15.30GMT) the Laser Interferometer
Gravitation-Wave Observatory will announce if they've found gravitational
waves or not after its recent upgrade. Before the upgrade LIGO could detect
binary neutron star mergers 50 million light years away, after the
upgrade it could detect them 650 light years away, a volume over 2000 times
larger. The physics world is full of rumors.
