The Higgs Field...
...pervades the universe, and is more or less just a way of saying spacetime.

At the Big Bang, there was not enough room for even photons to exist in the free state.
"[Higgs, et al] suggested that all particles had no mass just after the Big Bang. As the Universe cooled and the temperature fell below a critical value, an invisible force field called the ‘Higgs field’ was formed"
At the critical point, some photons escaped, and I postulate that photons created timespace.
Timespace is moving in every direction at once at C, the so called speed of light. Photons merely attach themselves to time, much like a rider on a streetcar. This is why we say that photons do not experience time. (And why time slows as you move through space.)
OK... if you are with me so far, let's jump back a bit, there is nothing in the Universe except photons. In the Big Firecracker, all the photons in the universe existed in what i call the "Packed" state, but immediately began to attempt to expand into normal photons. As the universe expanded, there was more freedom of movement, and the photons were able to interact with each other in patterns which were persistant. EVERYTHING is built from these dancing photons. In future lines of research, we should be able to determine these patterns. We might find, for example, that the difference between an up quark and a down quark is merely the polarization of one of it's constituant electrons.
But wait, there's more! Let's go back to our single photon, it attaches to time space and moves at C. But now let's consider a proton, it has many many photons, each attempting to attach to timespace, but unable to move with it because it is bound to all the other photons in its "matter dance." So instead, timespace flows into it.
So a very tiny portion of timespace is now attempting to attach to our proton and is slowed by it. Now scale this up a bit to the size of your hand. Now sufficient timespace is being attracted to be discernable. Move your hand to the left, and a portion of timespace moves left with it, wave it back and forth, and you can feel timespace resisting the changes. Now scale this up to planet Earth, and the amount of timespace flowing into to it becomes so great that your hand, along with the rest of your body, in attempting to attach to timespace is dragged toward the center.
Ordinary photons passing near the edge of your fingernail appear to be bent because the matter in your fingernail is warping spacetime. Go ahead, read this text with a fingernail, pencil, or whatever matter is at hand, look closely at the edge, and you will see this for yourself!
