Well the best way I can explain it (as I see it) would be...
Take a ball of sand in a vacuum like space. Considering it is unlikely an explosion of any type is uniform, in the initial blast, some sand would travel faster then others. Having no friction the sand should travel forever, but faster sand collides with smaller sand changing course and speed. Soon you will end up with groups of sand and as a definite in the universe, 1 individual grain of sand will be attracted to 2 grains of sand in a group, and 2 to 3 and 3 to 4 and so on and so on. Eventually your spray of sand will form into clumps. Smaller clumps are attracted to bigger clumps and so on. Theatricality making its way back to the a single unit. If you believe that gravity acts in the same way as matter, in a blank vacuum with no obstetrical, that would be what you would expect.   See 6 other replies

Yes, we need faster than light imaging/sensors. For one, they would be less distorted because of gravity would have less of an effect then it will on light. But mostly because it will let us see events closer to real-time. As is, we are looking at events happening millions of years ago do to the travel time of light. If we could view images thousands, even hundreds of years old then we would have a much better understanding of the universes current condition.

As for measuring gravity waves, I'm guessing that if you can find the exact position and distance of a star then find a body in between or near the star or earth who's gravitational force distorts the light of the star to a point where it appears in the wrong location, you should have some idea of the gravity imitated. I would figure measuring gravity waves would be a good estimation based on factors such as time, distance, and distortion like that.   See 6 other replies

hmm if they find a better way too see then they could be like space ultra sound .... is tehy are fatser than light we may know of a black hole b4 the light disaper or a nova b4 it happens that would be a crazy big as ultra sound tho :P   See 6 other replies

one question tho ... i think they would meture new waves from resent event but how would they meture the big ban if is something really old and the way may have pass by .. do u think that thos gravity waves are eternal or they would eventualy stop like they do on water ... and if they stop how long would they travel b4 they and how fast ... could they be faster than light?   See 6 other replies

I think it's a bit more complicated than a twenty-minute educational video lets on.The answer, I believe (someone correct me if I'm wrong), is that despite the common expression that Relativity says "everything is relative", there are actually some constants which are not relative. The speed of light, for instance, is always constant, no matter how much space-time grows, shrinks, or curves.Mind you, it's true that there's a lot of noise. But there are ways to estimate the expected noise level in absence of gravitational waves. If LIGO measures nothing but noise, even when its sensitivity is increased over the next few years, that would be an extremely interesting result.   See 6 other replies
