JohnSSM Posted January 21, 2015 Share Posted January 21, 2015 (edited) It seems that all, somewhat massive objects, create gravity (curve space-time). But is this the same act of creating gravitational waves or radiation? It seems that gravitational waves exist when objects interact in each other's fields. But does this account for more gravitational force (curvature) or just ripples within it that effect time and length distortions?The question that i could not answer while reading was..."Does gravity exist beyond this radiation of waves or not?" There is gravity created by GR and then there are sometimes radiations of gravity which actually "shed a bit" of the gravitational force it had....and they "travel" out through the field...but will a gravity wave actually change the "weight" of objects as it passes through? The sun creates gravity on its own...or, it could...but with every object that shares an orbit with the sun, waves are created...so gravity doesnt exist as that radiation...gravity is what is being radiated through?There's some confusion here...

JohnSSM Posted January 21, 2015 Author Share Posted January 21, 2015 Gravitational waves are the ripples, not the underlying curvature http://en.wikipedia.org/wiki/Gravitational_wave I never knew wikipedia had such thorough info about this stuff...I was never sure how much to trust it though...seems like yall trust it...the section of gravity waves is filled with great info... It seems that most objects in the universe will radiate waves...it basically comes down to symmetrical events and/or objects and their acceleration... IS this process of radiating its own energy away at all likened to the weak force or entropy in general? it actually seems more a victim of angular momentum...then again, maybe the entire weak force is based on angular momentum and loss.. Its becoming very clear to me that spin and orbits are basically the same thing...an object having spin unto itself could be seen to be orbitting its own differences in symmetry...as if symmetry is what is being equalized or conserved by all the gravitational effects... One thing that hasnt been made clear to me is whether or not objects in orbits or spins have less gravity than they would if not orbitting or spinning...in the example of the binary star system, would those two objects create more gravitational effects if they were separated into open space away from each other? I basically need to figure the gravitational energy for both stars in a vacuum, then figure the gravitational energy of the stars in a quickly rotating binary system and compare the gravitational energy...they way I understand it, the sum of the 2 stars' gravitational forces measured in open space, would equal MORE than the gravitational force of those same 2 stars positioned into a binary system...I did read the entire entry and might have missed this point in the equations...

swansont Posted January 22, 2015 Share Posted January 22, 2015 Gravity is separate from the weak force. Rotation causes the Lense-Thirring effect, but this changes the precession and not AFAIK the actual strength of gravity. http://en.wikipedia.org/wiki/Frame-dragging http://en.wikipedia.org/wiki/Gravity_Probe_B Link to comment Share on other sites More sharing options...

And WOW... "The geodetic effect (also known as geodetic precession, de Sitter precession or de Sitter effect) represents the effect of the curvature of spacetime, predicted by general relativity, on a vector carried along with an orbiting body" Im so glad I have the name of the concepts that can verify how I have viewed it correctly and flat out wrong... The Lens Thirring stuff is also amazing...frame dragging is a tough one to view without "friction" between fields...I suppose when I get to the bottoms of every theory that describe different aspects of GR, Ill have to move onto field theory and all the particle stuff...

If you aren't sure on the veracity of a Wiki page, have a gander through the listed references at the bottom and the credentials of those who wrote them. Also, the reference list can be a useful place to start exploring a subject from, particularly if the page author is an expert.
