special relativity has to do with constant velocity motion, spacetime, and observers. it is a special case of general relativity (hence the name 'special'). it says that constant velocity motion contracts lenth, dilates time, and increases massenergy.
general relativity says the the effects of acceleration and gravity are indistinguishable. i know that gravity dilates time, but does it contract length?
