Physics of Time Travel
Transcript of Physics of Time Travel
-Predestination Paradox Rules of Time Travel Immutable Timelines
Alternate Histories Physics of Foward Time Travel Fast Speeds (Special Relativity)
Gravity (General Relativity)
Biological Velocity Based: Time Dilation Twin Paradox Gravity Based: Sitting in a hollow, high mass object
Sitting on the event horizon
Sitting in a black hole Biologically Based: Time Perception
Suspended Animation Physics of Backwards Time Travel: Retrocausality a measured or measurable period
a continuum that lacks spatial dimensions. Time is a sequence of moments in a linear order. Physics - Doctor Who - A big ball of wibbly wobbly, timey wimey...stuff. a collection of objects called “times” that ultimately reduce to relationships among events. Backwards Time Travel Problems and Physics of: Faster than light travel Wormholes Parallel Universes Works Cited http://en.wikipedia.org/wiki/Time_travel http://www.iep.utm.edu/time/ http://en.wikipedia.org/wiki/Time_in_physics Future/Present can affect the past Matter/Antimatter http://en.wikipedia.org/wiki/Retrocausality http://timetravelphilosophy.net/ The Self-Visitation Paradox Can one go back in time and visit oneself?
Could one person be in two places at the same time? Bootstrap Paradox Information has no origin Predestination Paradox aka: Causality loop Attempts to change the past actually cause the future Example: The play Oedipus Solutions to Paradoxes Property Compatibilism Solution Relativizer Solution Spatial Parts Solution Parallel Universes Not really "Time Travel" Experiments involving Time Travel Delayed choice quantum eraser
Enticing future humans to time travel
-'Time Travel Day' Theory of Compossibility Ideas from Fiction Gradual or instantaneous Time Travel Most fiction uses instantaneous
-Energy is expended
-Machines involved Some Fiction is Gradual HG Wells explains that we move through time at a constant pace
-Travel by accelerating through time Time travel and Spacetime Travel Time travel doesn't change position Spacetime travel is needed for traveling to the past on Earth, etc.
