Unformatted text preview: (c) Light waves move with respect to what? (d) Images dont arrive from an object traveling at v at speed v + c . 5. Cosmos Episode 8 Second clip Setup: What would the world look like if one were able to travel close to the speed of light? (a) Clearly not part of our everyday experience but all tests made to date agree with special relativity. Well see many examples over the next few weeks. (b) Length contraction: Back of the fast body catches up to front due to high speed (approaching speed of light) length contraction (c) Images in front are blue-shifted (shorter wavelengths of light), peripheral images (and behind) are receding at close to speed of light and thus red-shifted (longer wavelengths of light). (d) Time dilation twin paradox harder to see physically but will be a consequence of our math....
