The Higgs is responsible for Mass, Gravity is different. The Graviton if it even exists would be nearly impossible to detect directly. Gravity is incredibley weak, the Detector would have to be huge. I'm talking the scale of Solar System and maybe even a entire Galaxy. I read somewhere that a Detector the Size of Jupiter close to Neutron star would collect 1 Graviton every 10 years. It would have to run for Millions of years to collect enough data. You have to think in Spacetime. Everything is really moving at C (Speed of Light) or all of Inertia is C in Spacetime. Neither Space or Time is absolute (Meaning the same for every point in the Universe) only Spacetime is absolute. This is why so much Energy is in Matter, It's Intertia is always C. Now consider a Masslass Particle ie a Photon all of its momentum is in the Spacial Dimensions (3D Space) but it has no momentum in time (Never Ages). All Particles with Mass have very little Momentum is Space in Respect to C and Most of the momentum is in time. On the most fundamental scales the Higgs field has something to do with this. Some Particles are just moving at different Angles in Time with Respect to Space. Its Same if your Traveling North at 60 MPH, then start to turn a few degrees West at a Constant speed. Most of your speed is North, but some of it goes West since your moving at different Angle in Space. Massive Particles Move faster in Time, Hence Decay faster. The Higgs field has something to do with that, just can't describe it words right now. Gravity might not be a force at all, just be a Lag or Warp in Spacetime. Meaning Space and Time is never the same, we just don't notice it in the Marco world, but on the smallest scales its very profound. Maybe enough so that its responsible everything we see today. If everything Moved at C in Space there would be no Time. Same is True if Everything Moved at C in Time there would be No space. If Photon moves entirely at C in space but not in Time and Particles with Mass Move at a Angles in SpaceTime, then what would a Particle that moves at C only Time look like. I would not exist in 3D Space and be Moving Faster in Time then everything. Could that be a Graviton or something else.
There is no reason why Stuff can't move backwards in Time.
Now what happens if Everything Moves at C in Time (No Space) and if Forward moving Stuff collides with Backward moving Stuff. Lets Call that Stuff Energy. That collision Slows or Stops its Inertia in time Since Energy is conserved it has to Go somewhere so why not 3D Space. The Forward Stuff becomes Matter and backward Stuff becomes Antimatter. Now what if its Almost a 50/50 mix with the just slightly more Forward Stuff. 3D Space would appear to erupt from a Singularity and be full of Matter and Antimatter (Everywhere). The Matter would annihilate all of the Antimatter, Leaving small percentage of Matter. Kinda sounds like the Big Bang/Inflation doesn't it.
This could be happening at all points in the Temporal Dimension each collision creating a whole Universe with Different Physics. Only Collision with Near equal amounts of Forward Stuff and Backward Stuff create a stable Universe. What we see as the Universe might be a illusion. Of course its much more complicated then this, I like this viewing this way in a Relative way :)
Paints a good picture of Spacetime. Could be why Both Einstein and Quantum Physics are both right. Its kinda Hard Picturing a Single Dimensinal Universe that is Infinite, with a Infinite number of Bubble 3D Universes all base on one Simple law that Nothing Can Be Created or Destroyed, Ultimate Law of Conservation.
Please excuse my poor Physics and Bad Grammar, I'm a Software Engineer.
