- Here is a related question , taken from a caller's question to Vig
- Teplitz (chrmn, Dept of Physics, SMU) during a Dallas public radio talk
- show :
-
- Does gravity bend different frequencies of light by different amounts,
- and if it does is it possible to form an "Einstein Rainbow" ? (In
- analogy to the recently seen Einstein Cross, which is formed by light
- from a distant quasar being bent around an intermediate galaxy.)
-
- I think I know the answer, but I would like to see the consensus
- of the group before I venture my guess...
