Relativistic Visualization - The State of the Art Don V Black April 16 th, 2004 Videos courtesy of Daniel Weiskopf's PhD Dissertation, Visualizing Four Dimensional Spacetimes Title Slide

Facts of Life in our Universe. 1)Four Dimensional Spacetime (3+1 Dimensionality) 2) Finite Speed of Causality (or 'c' - the speed of light) 3) Resolution of spacetime is the Planck length (~ m) 4) Physics: Standard Model vs. Exotic Models Facts of Life

Einsteins Two Theories of Relativity SR - Special Relativity Euclidean or Flat Space Lines are all straight A lightray shines in a straight line GR - General Relativity non-Euclidean or Curved Space Lines are all curved A lightray is curved

Exotic Physics Models Kaluza-Klein - (4+1)D = 5D String Theory (curled up) - 11 (10+1)D, 27 (26+1)D LXD (Large Extra Dimensions) - infinitely many Generic Dimensionality - x(m+n)D 4 (3+1)D, 5 (4+1)D, 10D, 26D, 6 (4+2)D Exotic Physics Models
