Einstein’s Cosmic Speed Limit: Relativity in Science Fiction https://www.youtube.com/w atch?v=Kj178APgdno 1900 – 1945: The Golden Age of Physics Two revolutions: Relativity and Quantum Mechanics 1. Special Relativity 2. General Relativity You cannot exceed the speed of light!!! 70 miles per hour 10 miles per hour 60 miles per hour Maxwell’s equations predicted a new kind of radiation travelling at 186,000 miles per second.... V U Before Einstein: total speed = U+V After Einstein: total speed = U+V 1 + UV/c2 How does SF deal with this cosmic speed limit? 1. Accept it (universe ship, time dilation, hibernation) 2. Ignore it (warp factor 8, captain!) 3. Evade it (wormholes...) Robert Heinlein Next Week Aliens.....
