Scientists have spent decades and billions of dollars on this quest. They have built giant atom smashing machines to probe how the four fundamental forces actually work. They v found that down at the microscopic level billions of times smaller than atoms forces are actually caused by the movement of tiny particles. Electromagnetism is carried by photons. The strong force is carried by particles called gluons. The weak force by particles called the W and Z bosons. By they've never found the force carries for gravity. The illusive gravitons. And that's where the efforts to unify the math of the Universe stucked.

But wind gate physicist and compulsive surfer Garret Lisi could be on the cusp of succeeding.

"Right after people got the idea that there were these weak and strong forces which were put in the end of the 70-s, almost immediately people saw how they fit together to make a Grand Unified Theory unifying those 3 forces. Now, it is much trickier to try to bring the gravity into the picture because it is slightly different."

Trickier is not the statement. The greatest minds in physics of all had given up when unifying gravity and it's unseen gravitons with the other 3 forces. But then Garret had a vision. A vision of twisted circles.

"I was working on just how this whole algebraic structure fit together. A gravity and the other forces. And I started to wonder if this thing could be understood as a whole. This entire structure could be described as part of some larger Lie group. A Lie group is a mathematical shape that is a collection of circles twisted around each other in a specific pattern. Now the simplest Lie group is just a circle. Now if you take a second circle and you wrap it around the inner circle keeping it perpendicular you'll get what's called the torus which is like the surface of the donut. But if you take the third circle and keep that perpendicular to the other two and you twist it around the inner circle as you wrap it around, you will get all three of those circles twisted around each other to form a 3-dimensional shape."

But, this is only the beginning. Garret kept on twisting circles around one another until he has done it 248 times. The end result is a shape so complex that it can't even be fully appreciated in 3-dimensions. It's called the E8 Lie group. To us it is just a mind bumping pattern. But Garret Lisi realized the way the circles twisted around one another looked just like the way various fundamental particles interact.

"In physics each one of these circles can be associated with a different kind of elementary particle. One circle could correspond to electrons. The other circles could correspond to the force particles such as photons, or weak force particles, or strong force particles, the gluons."

For months Garret turned this kaleidoscope over and over in his mind. And then ...

He found a set of circles that seemed to act like a never yet seen graviton. And for the first time in the history of physics a mere mortal saw how gravity might fit in with all the other forces and particles.

"Yo seeing how gravity could be combined with these other Lie groups during this unification was one of the greatest moments in my life. "

Garret calls this dizzying geometrical relationship between all the particles and forces in the Universe an exceptionally simple Theory of Everything. It predicts several as yet undiscovered particles and scientists across the world are on the hunt for those right now.
