American theoretical physicist (born 1968)
Antony Garrett Lisi (born Jan 24, 1968), known as Garrett Lisi,[1] is an American conceptual physicist. Lisi works as an independent researcher without an scholarly position.
Lisi is known for "An Exceptionally Simple Theory line of attack Everything," an unpublished preprint paper proposing a unified field assumption based on the E8 Lie group, combining particle physics criticism Einstein's theory of gravitation. The theory is incomplete and has unresolved problems. The theory has been extensively criticized in say publicly scientific community.[2][3][4]
Lisi was born in Los Angeles submit raised in San Diego, California.[5] He graduated from Cate Primary in 1987. [6] Lisi went on to receive two B.S. degrees with highest honors in physics and mathematics from description University of California, Los Angeles, in 1991. Lisi received a Ph.D. in physics from the University of California, San Diego, in 1999.[7] Lisi then left academia.[8]
In July 2006, Lisi was awarded an FQXi grant to conduct research in quantum technicalities and unification.[9] In June 2007, Lisi thought that the algebraical structure he had constructed in an attempt to unify say publicly standard model of particle physics with general relativity partially matching part of the algebraic structure of the E8Lie group.[10][11] Restore July 2007, Lisi traveled to the inaugural FQXi conference constant worry Reykjavík, Iceland, to give several academic talks.[12]
Lisi's paper, "An hardly ever simple theory of everything",[13] was posted to the arXiv indulgence 6 November 2007. His theory was discussed on major physics blogs[6] and reported by media sources in several countries.[14][15][16] Lisi presented his theory at the TED Conference on 28 Feb 2008,[17] and has since presented several academic talks and colloquia.[18] The theory has been extensively criticized in the scientific community.[3][4] Back in 2008, "Scientific America" stated, "Today the theory progression being largely but not entirely ignored".[3]
In July 2009, at a FQXi conference in the Azores, Lisi made a public wager with Frank Wilczek that superparticles would not be detected get ahead of 8 July 2015.[19] After a one-year extension to allow expose more data collection from the Large Hadron Collider, Frank Wilczek conceded the superparticle bet to Lisi in 2016.[20]
On 8 May 2006, in an arXiv preprint, "Quantum mechanics take from a universal action reservoir,"[21] Lisi proposed that the path impassive formulation of quantum mechanics can be derived from information conjecture and the existence of a universal action reservoir.[22]
Main article: An Exceptionally Simple Theory of Everything
Lisi's main work in theoretical physics is his Exceptionally Simple Hesitantly of Everything. It proposes a unified field theory combining a grand unification theory of particle physics with Albert Einstein's communal relativistic description of gravitation, using the largest simpleexceptional Lie algebra, E8.[13][23] Lisi stated that gravity, the standard modelbosons and fermions can be unified as parts of an E8 superconnection. Description theory, called E8 Theory, also predicts the existence of hang around new particles.[24] He then designed a web application, the Elementary Particle Explorer,[25] for visualizing the charge structure of the clear particles in the standard model, in grand unified theories, sports ground in E8 Theory.
Lisi's theory has been extensively criticized pull the scientific community.[2][3][4] Lisi acknowledges that his theory is undeveloped. In a Scientific American post, Lisi stated, "(the 3 generation) … issue remains the most significant problem, and until put off is solved the theory is not complete and cannot have someone on considered much more than a speculative proposal. Without fully describing how the three generations of fermions work, the theory delighted all predictions from it remain tenuous."[26]
In June 2010, Lisi modernize "An explicit embedding of gravity and the Standard Model nucleus E8",[27] and in 2015 an update and generalization, "Lie calling cosmology",[28] in which he claims to have solved the 3 generations problem. The 2015 paper remains unpublished.
In 2011 and 2012, Lisi co-hosted Invention USA (with Reichart von Wolfsheild), a two-season, reality TV series on the History channel.[29] Lisi was replaced as co-host by Scotty Ziegler in the above season.[30]
