Thread: Can Gravitational waves be absorbed by matter?

Can gravitational waves be absorbed? Or do they just pass through everything and curve space time as it passes through?

Do you think the waves are composed of anything?
If so than it would seem possible. But what are they composed of.

And if they arent composed of anything, whats to absorb?

The meaningless response to this is to cast aside wave or particle stream mechanics.. or wave signature actions.

But instead focus on the science we know..

That the presence of mass does effect the space it is in.

It does not get blocked, absorbed or other wise dampened by anything other than distance..

From my understanding they are changes in the gravitational field ... or if you prefer changes in the warping of space time.

Thanks ... this is how I understand it also.

Can energy be gleaned from it?

We don't know whether gravity works by waves or particles or something else, so there is no reason to refer to "gravitational waves" as something real. But gravity clearly does affect things, so whatever its mechanism, its interaction with matter must reduce the original srength. This would lead to gravitational shadows, or reduction of gravitational strength behind objects. There is some evidence for this in the work of Allais, see Professor Maurice Allais - a genius before his time - as are they all and Allais effect - Wikipedia, the free encyclopedia and in the results of Wang and Wang [1003.4947] Precise Measurement of Gravity Variations During a Total Solar Eclipse

I would challenge that conclusion.. and argue thus...

At the local coastline I took particular notice of the tide hight.. Last Sunday morning...

It lags behind the actual moment by some hours but the effect is clear to me.. regardless.

As some cloud cover spoiled the viewing of that eclipse.

I found a alternate way to wast the hours waiting for clouds to break.. They did not.

I walked down the beach... at 3 am its very nice.

Now I know that a beach is not the best way or sight ( site ) to view tidal movement but I observed DIRECTLY..

That the tide came in in the usual manor.. It continued to rise unabated by the shadow it went through...( The Moon )

High tide came and went just as It always does...

The conclusion is that the light from the sun when blocked by the Earth does not effect gravity force...

Turn this event into a Solar eclipse and the same result would be expected..

The moon does NOT interrupt gravity force measured at all..

Where is the evidence of a contradiction.. I know of none.

Can Gravity Waves or Force be interrupted by mass.. NO.

I was under the impression that the gravity was increased by adding mass to the system regardless. That if a body of mass was introduced a common centre of gravity would be acheived and that the gravitational field would be increased in relation to the added mass?
Would this not mean that the gravitational wave would be ammplified rather than dampend?

As with light, gravitational waves can be lensed by gravity.

The term "wave" when used with respect to gravity is a misnomer, as it implies an oscillation. Using an analogy of electric current, gravity is DC, not AC, and can never be negative i.e. there's no area or region of space where objects are pushed away by negative gravity.

an unnamed alien from a place far far away communicates a couple of messages.. directly to this forum so that a particular genius-to-be will read it and change the world (for the better I hope):
1> our friend's advanced civilization has a device we should call "a healthtrometer". It has scanned all humans and watched for consistent patterns. Its found that a large assortment of people who ingest the pretty little diminutive gem-like items we call "pills", apparently because of a mysterious force not fully understood (by our friends) called "marketing", are very unhealthy, and apparently the more we consume them the more likely we will be unhealthy. They advise us to quit consuming these unhealthy products and quit watching all ads at once. We should then expect healthier lives.
2 > we've got it all wrong with this "gravity" thing, due to it's correlation with objects of immense mass. Turns out it's not the mass of objects that cause gravity. Our friend supplies but one hint: it's actually not the "mass" that counts, but it's sort of like what you do with it. Apparently our friend isn't too friendly; ..just likes supplying puzzles.

Sorry, I'm a creative writer! I just want to know how certain scientists are that "mass" causes gravity. I know its probably 99.(follow this with a trillion more 9s) certain... Or would that actually be just a few more 9s after the decimal of certainty? Is there a chance that the big stellar objects have gravity because of some other force that has a relationship with mass? Have Scientists actually measured gravity from small masses? Thanks
