Garrett Lisi

Garrett Lisi wrote an online scientific paper entitled "An Exceptionally Simple Theory of Everything" that has the physics community talking. It is an attempt at the universal theory of everything, to replace the Standard Model.

Lisi's theory is considerably more simple than the rival model of string theory.

His theory is based on the mathematical shape, known as E8.

Being poor sucks," Garrett Lisi says. "It's hard to figure out the secrets of the universe when you're trying to figure out where you and your girlfriend are going to sleep next month."

About the current "Standard Model" of particle physics

The Standard Model of particle physics is a theory that describes three of the four known fundamental interactions between the elementary particles that make up all matter. It is a quantum field theory developed between 1970 and 1973 which is consistent with both quantum mechanics and special relativity.

To date, almost all experimental tests of the three forces described by the Standard Model have agreed with its predictions. However, the Standard Model falls short of being a complete theory of fundamental interactions, primarily because of its lack of inclusion of gravity, the fourth known fundamental interaction, but also because of the large number of numerical parameters (such as masses and coupling constants) that must be put "by hand" into the theory (rather than being derived from first principles).

The four forces are:

Interaction	Current Theory	Mediators	Range(m)
Strong	Quantum chromodynamics	gluons	10^-15
Electromagnetic	Quantum electrodynamics	photons	infinite
Weak	Electroweak Theory	W and Z bosons	10^-18
Gravitation	General Relativity	gravitons	infinite
