Why do some quasars have redshifts greater than 1?
 
  A) They are made of different elements than any other objects in the universe.
  B) They are very distant, with relativistic redshifts that take into account dilation of space-time, as Einstein predicted.
  C) They are made of tachyons and thus are able to move away from us faster than the speed of light.
  D) Einstein proved it is impossible to have a redshift greater than 1; these are all due to gravitational lensing tricking us.
  E) They are moving towards us, which throws off our spectrometers.

This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
