If you had a photon that was circulating around itself it could gravitationally orbit itself at very small scales because at planck scales the photon always appears to be in at least two places at once. You could in this case have a photon which appeared to be at rest by constantly travelling in a tiny circle. That's essentially the higgs boson - light crystalized into matter

The same goes for when the universe begins expanding too fast and all photons are ripped apart. Then all photons will be unto themselves and will appear unto themselves to be at rest. Our entire universe in fact is one photon that appears, unto itself, to be at rest, though it is moving and accelerating in a higher dimensional sense which is causing it to expand and that's why even a photon that appears to be at rest will have mass (the so-called higgs boson). The universe only has a finite lifespan dictated by how it is moving and accelerating in the higher dimensional reference in which it is like one photon. The photon is the most discrete unit of mass. It is a discrete unit of consciousness also.

As a photon the universe is a quantum tunnelling object caught in the dissallowed region - the time within time - between two higher dimensional parallel reference frames. Any object can exceed the speed of light by quantum tunnelling. Any time an object exceeds the speed of light it is mimetic of the creation of the universe. It sets up a time within time in the dissallowed region between where it leaves and where it arrives. This is the essence of teleportation or travelling massive distances in an instant. If you travel beyond the bounds of your visible sphere you will end up in an alternate universe which may resemble the past.

The time within time that any quantum tunnelling object sets up is the loop represented by our universe and it's discourse between creation - big bang - and destruction/reversal - big rip! The universe will rip when the inexorable expansion, which is said not to be in an inertial reference frame, exceeds lightspeed across a planck distance.

The universe is a causal time loop set up because it is possible for humans to send something faster than the speed of light and be masters of the universe like we already have 1/0 times before. In order to send something faster than TSOL an object must be accelerated from one speed, that is lower than TSOL, to another speed, that is greater, in less than one planck second. In this case the force required must be calculated from the initial speed, not the subsequent speed.

ps. please say what you mean by photons are anti gavitonic
