two people in a couple revolving, megacorporations with satellite business, suns and planets, planets and moons, gravity on every level and everything's an entity , grouped or not.

Well, gravity is there indeed.

I never thought about the waves like this though but it makes total sense, if a massive object causes a dent in the fabric of space(time) then motion creates ripples, but what does it consist of ?

Accelerating masses create ripples in fact. Not any motion.

is this what you call "gravitons"? and so gravitons are massless particles, pure energy, like fotons ? only fotons DO have mass when moving, right ? since that's why you can't go faster than light according to accepted theory, mass becomes infinite (thats why i keep saying all you need for FTL is infinite amounts of energy - on an abstract mathematical level lol)

Gravitons have not been observed yet. In fact, there is probably no way (at least today) to observe them by virtue of their tiny interaction strengths (assuming they exist). And what you said is correct: of gravitons exist, they are massless.

i see the waves though if i think about, two whales dancing around each other in the big steem-sea , attracting all those dolphin due to their massive size, in turns attracting all those minnows due to the combined mass of this mini galaxy
and all the plankton round it :p

interesting thoughts :)
