I was wondering......is there an end to the data that we are processing or is this an on going search that wont stop till it's found or when the funding runs out?

I beleive that it is the latter.
That would be my take as well. There are plans for S4 (I'm using "plans" only because I'm not sure if the data collection for it has started), it should be even more sensitive than the data we are running from S3 now.
Being one of the last predictions of GR not to have been observed, it will be years before this project will out live it's usefullness. Finding the waves, or perhaps more signifigantly not finding them, would be the equivilant of SETI finding an alien signal. The implications would be huge. In five years, we will be talking about the "early days" here too.
My only question, is how can we use the ability to detect them after we can find them? What can they tell us about the universe out there?

i saw a response from a scientist, in an article, i cant recall from where, anwsering a similar question to the last one in your post...........i love his anwser to this!....."asking what you can do with Gravitational Ripples is akin to asking....what can you do with electricity?"
Gravity waves are the equivalent to sound waves in air. If a balloon pops in the far distance we can hear it due to the motion of the air rippling away from the point of burst. But only to a certain distance. Gravity waves work on the same principle. If a star goes supernova the dark energy within the surrounding space will carry the gravity ripply outwards. But to what distance? That is the question....

sorry bout the typo...... faster THAN light?
also i would guess that the source of the ripple would determine its speed?.........i guess what i would like is a link to the theories about ripples

Correct, The dark energy is the medium in which light travel (and gravity) travels. Just as the speed of sound varies in different atmospheric pressures so does gravity and light in different parts of the universe based on the densness of the dark energy in that region of space. IMHO.
> also i would guess that the source of the ripple would determine its speed?....
No, the speed of gravity waves (and light) is constant (relative to the density of dark energy in that region of space). Photons (and gravity ripples) will be a constant speed in both a small and large supernova.
Is there an end to this?

can gravity move/travel faster then light?
thanks

My understanding was that gravity waves move AT the speed of light.

Mr Gravity, I could be mistaken, but your description of dark energy sounds suspisiously close to the Fin-De-Siecle idea of the "ether."
