Relativity can be described using space-time diagrams . ... Thus two observers moving with respect to each other can still agree on the time, and thus the distance between two objects, which is the difference in their positions measured at equal times, can be defined. ... If it did, then the rate of a "bouncing photon clock" moving with respect to the ether . ...

Next: Summary Up: The Epsilon Aurigae Previous: Eclipse Lightcurves for . In this section, we attempt to account for the observed asymmetry in absorption line profiles by using a crude model of the thermal expansion of the outer edge of the disk as it rotates into the radiation field of the primary. ... Hinkle and Simon (1987) proposed that the asymmetries in the pre- and post-central eclipse line profiles are a consequence of the vaporization of grains caused by heating from the primary. ...
