I have a question and/or a thought on dark energy. I have just 2 years of college Physics so I apologize if my question seems stupid. However, I was thinking about dark energy and the weakness of gravity relative to the other forces and the idea of living in a finite universe. Then I read an artice on discovery news about the gravity wave detector. Is it plausible that gravity is weak compared to the other forces because gravity waves propigating out from a large enough source such as an entire galaxy, reach the edge of the universe and reflect back, like waves in a pool? There fore effectively cancelling some of the waves out and decreasing its strength as a whole? Or, if a star goes Super Nova, and the "dent" the star makes in space springs back like a trampoline effectively sending out a ripple through space that creates a similar effect(after further thought maybe this could include galactic centers with massive stars rapidly orbiting a super massive black hole moving a bunch of these"dents" around quickly causing waves)? Secondly, could dark energy simply be an effect of the relative weakness of gravity? Meaning that the energy in the universe left over from the big bang and rapid expansion is slightly above the maximum expansive energy gravity could overcome, and the larger the universe gets gravity gets "spread so thin" the expansion accelerates? Could Dark Energy possibly be detected or explained by studying its effect on gravity? Again I apologize if my question is alittle dumb.
