This discovery is important and proves out a personal conjecture that I was hesitant to assert. I have submitted a paper describing a fundamental metric able to exactly map the impressed curvature produced by a hypothesed fundamental particle. It also makes possible a detailed mapping and description of photons. It was apparent that these could also interact with each other and was predicted by the mathematics. In fact I began describing photons as partially bounded curvature and the fundamental particle as a bounded curvature to emphasize the metaphor. This was a conjecture waiting for convincing experimental proof here at hand.
The interactivity was suspected but not clearly demonstrated.
More practically, we are now on the way to designing fully optical devices with no need to kick an electron around. This will essentially optimize computer technology to its possible final size limits for any given temperature regime. Maybe we finally will get to see the final culmination of Moore’s law.
The advent of a GUT for will leave open one remaining question in physics. It will be how to characterize photons and map their interactions. We are just nibbling at it now and it becomes seriously interesting when you contemplate the output of a quasar. I have made the conjecture that galactic jets are initially photonic in nature that escape their incubating event horizons at light speed and then reform as particles kicking out visible light and cosmic rays. This interactivity between photons was an obvious precondition for that curious conjecture. Now I have the necessary confirmation of both repulsive and attractive behavior.
Years of work remain here, but we have a good beginning.
Light's Repulsive Force Discovered

A newly discovered repulsive aspect to light could one day control telecommunications devices with greater speed and less power, researchers said today.
The discovery was made by splitting infrared light into two beams that each travel on a different length of silicon nanowire, called a waveguide. The two light beams became out of phase with one another, creating a push, or repulsive force, with an intensity that can be controlled; the more out of phase the two light beams, the stronger the force.
"We can control how the light beams interact," said Mo Li, a postdoctoral associate in electrical engineering at Yale University. "This is not possible in free space — it is only possible when light is confined in the nanoscale waveguides that are placed so close to each other on the chip."
Li and colleagues previously discovered an "attractive" force of light and showed how it could be manipulated to move components in semiconducting micro- and nano-electrical systems — tiny mechanical switches on a chip.
"This completes the picture," Tang said. "We've shown that this is indeed a bipolar light force with both an attractive and repulsive component."
The team, led by Yale assistant professor Hong Tang, details its findings today in the online version of the journal Nature Photonics.
The attractive and repulsive light forces are different than the force created by light's radiation pressure, which pushes against an object as light shines on it. An example of where this can have great effect is on an asteroid, which over millennia has its orbit around the sun altered by subtle but constant radiation pressure, or with solar sails, pitched as a way to ride the sun's pressure into the deep cosmos.
The newfound forces, however, push out or pull in sideways from the direction the light travels.
Previously, the engineers used the attractive force they discovered to move components on the silicon chip in one direction, such as pulling on a nanoscale switch to open it, but were unable to push it in the opposite direction. Using both forces means they can now have complete control and can manipulate components in both directions.
"We've demonstrated that these are tunable forces we can engineer," Tang said.
An added benefit of using light rather than electricity is that it can be routed through a circuit with almost no interference in signal, and it eliminates the need to lay down large numbers of electrical wires, the researchers said in a statement.
The work was funded by the U.S. Defense Advanced Research Projects Agency and the National Science Foundation.
