- Or perhaps you are a believer that c = infinity? ;-) The relativity of
- simultaneity doesn't really mean that we should think of events on our light
- cone as "happening now." It is reasonable to adopt the frame of reference of
- the earth, the galactic center, or even the rest frame such that the 2.7 deg K
- black body radiation is isotropic, and to think of time differences between
- events within that reference frame.
