~ gravity travels at the speed of light; nothing can travel faster than light
~ lightning will cause a compass to go haywire
~ how do the strings of string theory compile electrons, etc?
~ gravity is weaker than electromagnetism (10^38 times stronger)
~ quantum mechanics is based on probability (?)
~ strong and weak nuclear forces (principles of atomic bomb)
~ radioactivity : weak nuclear force
~ the existance of black holes requires a unification theory of the theory of relativity and quantum mechanics
~ string theory : vibrations of energy
~ a black hole as the origin of the big bang (?)
~ if something is bumpy enough, it will appear smooth (I already knew this, but it is relevant)
~ Newton ranks higher than Einstein in physics circles
~ messenger particles create force
~ tachions travel faster than light
~ gravitons : massless particles
~ n = 496
~ resonance of strings responsible for physical properties
~ 11 dimensions, circular or as a line
~ extra dimensions "twisted and curled back on each other"
~ 20 fundamental constants of nature (caused by 6 dimensional shapes)
~ our universe as a slice of toast (brane), parallel universes compose loaf of bread ("the bulk")
~ wormhole : space bridge/tunnel; path of a string
~ Edward Witten
~ M = magic, mystery, or matrix (M theory)
~ dimensions : degrees of freedom
~ gravity may not be confined to our brane (closed strings)
~ theory  big bang as a result of two branes colliding
Yes, I am a geek. I watched this for fun.
