1 00:00:04,430 --> 00:00:02,030 a recently published paper by David 2 00:00:06,050 --> 00:00:04,440 Chester Michael Rios and Alicia mareni 3 00:00:08,450 --> 00:00:06,060 classified ways to recover the standard 4 00:00:10,310 --> 00:00:08,460 model and gravity from a real form E8 5 00:00:12,169 --> 00:00:10,320 their paper discusses the representation 6 00:00:14,030 --> 00:00:12,179 theory for the most common Grand unified 7 00:00:15,709 --> 00:00:14,040 theories combined with conformal gravity 8 00:00:17,450 --> 00:00:15,719 one of the areas that Garrett lisi's 9 00:00:19,130 --> 00:00:17,460 previous work was seen as problematic 10 00:00:20,769 --> 00:00:19,140 was that matter particles such as the 11 00:00:23,689 --> 00:00:20,779 electron and quarks typically require 12 00:00:26,210 --> 00:00:23,699 192 degrees of freedom while E8 can only 13 00:00:28,250 --> 00:00:26,220 work with 128. this paper provides a 14 00:00:30,109 --> 00:00:28,260 chiral matter lagrangian that uses extra 15 00:00:32,450 --> 00:00:30,119 time Dimensions to efficiently encode 16 00:00:34,010 --> 00:00:32,460 Mass flavor oscillations with 128 17 00:00:35,870 --> 00:00:34,020 degrees of freedom which is related to 18 00:00:37,250 --> 00:00:35,880 the so-called split octo-octonianic 19 00:00:38,870 --> 00:00:37,260 projective plane the mathematics 20 00:00:40,430 --> 00:00:38,880 Explorer provides the foundation for a 21 00:00:44,810 --> 00:00:40,440 new class of physical models one model 22 00:00:47,030 --> 00:00:44,820 isolates su-32 cross su5 inside E8 -24 23 00:00:49,010 --> 00:00:47,040 which includes su5 gut for the standard 24 00:00:51,529 --> 00:00:49,020 model with a new gravitational symmetry 25 00:00:53,990 --> 00:00:51,539 this allows for a single 248 dimensional 26 00:00:56,150 --> 00:00:54,000 representation of E8 to minimally extend 27 00:00:57,950 --> 00:00:56,160 a conformal grand unified theory with a 28 00:00:59,510 --> 00:00:57,960 new gravitational Higgs sector which may
