bitch, i'm fo sho wid it
Gravity travels through space with a speed, correct? And I presume it's safe to say that the speed in question is damn near close to c. In fact, I'm telling you--it is c. So I began to wonder... what else travels at the speed of light? Hmm.. nothing. Wait. Wait. I just find it remarkably interesting that two known things in our universe propagate at the same speed, and that same speed being one which matter in our universe is unable to reach (as of yet). So what exactly are photons and gravitons. Do they exist? Are they what we think they are? How do we know that gravity isn't light and that light isn't gravity? There are too many similarities for it not to be said. I mean, how can it not be said that gravity isn't just a different manifestation of light? What if gravity is just the motion of an electron in the 5th version of a 9th dimension--and the same for light? Hence; our inability to see the speed at which gravity moves.
Of course, on the surface, gravity and light have extremely different properties. I feel electromagnetic radiation every day, I see electromagnetic radiation every day. But I do not see gravity traveling. I see the effects of gravitational acceleration on objects, but not the gravitational communication between those objects. So, really, why can't gravity be light? Just because I don't feel the gravity's electromagnetic radiation (if it posseses such a thing). Because light isn't the attractive force between two masses? How do you know? Can it really be seen, can it? From a creature living in 3d space, can it?
Gravity = Light
Gravity-Light duality, you heard it first... here.
