Gravity waves have existed forever. Will their discovery feed the poor or alleviate human suffering?

Will they build an instrument tuned to gravity waves to "see" things?
Oz, advanced LIGO and Virgo took years in designing the sensitivity and couldn't see anything till recently. That would only mean the rate of astrophysical events is very low. We need to wait for some more time.
Surely the universe is full of such events? Some reports claim this latest discovery dates from the big bang
Yeah exactly Oz, it dates back to some 1.3 billion years. Amazing!
Doesn't that mean the waves should be seen everywhere?
No that particular phenomenon got over, based on that observation we will be able to explore further discoveries. In fact in the whole of universe explosion and unification of giant objects take place, we hope of getting the details in near future.
So do gravity waves cause gravity? I'm justt trying to keep up with the theory. Was gravity released during the big banv as another kind of wave?
Gravitational Waves cause gravitational radiations. As far Big Bang theory, this latest discovery is hope of knowing it even better. The present knowledge about the theory is that the solar system was a resultant of the big explosion.
Yes we all know about the big bang. I'm not sure why these are gravity waves and not just good old ripples in "time/space".
Yes, gravity waves are the ripples in the curvature of spacetime.
But haven't we known about those ripples for yonks? Aren't those ripples used as "lenses" to see further away already?
About a century ago we learnt of these ripples, but thought of them to be undetectable, however the advancement in the field and development of a highly sensitive instrument help detect the ripples.This discovery will help us see further.
