Dimensionality

Perspectives on Dimensionality

• = 11D brane bulk
  • 6D micro
  • 4D macro
• ≤ 11D has consistent supergravity
• ≥ 11D symmetry maintained and compact space
• ≥ 7D manifold at each quantum point + 4D spacetime
• Kaluza-Klein 5D spacetime
• M-theory
  • branes hold energy as tension in embedded superstrings
• 10-d-vision
